Product Release History

The PlantPredict application experiences a new release every two weeks. Major feature additions constitute a leading digit version increase (e.g. v3.12.0 to v4.0.0). Release notes are posted on this page when the release is live on production.

  • Release 10.14.0 Latest Release

    01 December 2022

    Single Sign On (SSO) and better integration between PlantPredict and the Terabase Development Platform

    As we prepare for the official launch of PlantPredict Pro coming up on January 1st, we had to implement single sign on so that navigation between PlantPredict and the Terabase Development Platform (a.k.a. Dev Platform) is smooth (no secondary login).  Beginning today, there will be a link in the navigation pane of PlantPredict that will allow PlantPredict users to smoothly launch the Dev Platform with the click of a button.  The Dev Platform will open without the need for a second login.

    Dev Platform Link

    Dev Platform is Free for everyone in December

    For the entire month of December the Terabase Development Platform (Dev Platform) will be FREE to all PlantPredict users.  Go ahead and click on the link and check it out.  If you need some instructions on how to setup a project, contact support@plantpredict.com and we will arrange a demo to help you.  Beginning on January 1st, 2023 only PlantPredict Pro and Enterprise subscribers will be able to use the Dev Platform for detailed design and optimization of their power plants.  So, use the month of December to decide if this product is right for you!

    We are also offering Early Bird Pricing through the month of December, so you can get 25% off the List Price which goes into effect on January 1st, 2023.  Click here to see details about the pricing of PlantPredict Pro and Enterprise:  https://plantpredict.com/pricing/

    Inverter Description has been added

    Inside a Block Builder Prediction, we have added an Inverter Description field so that users can now place a description/name of the inverter into their power plant design.  This is especially useful for our O&M customers and users who are using PlantPredict for their Digital Twin model and they want to call out the specific inverter in their as-built model

    Inverter Description

    BUG FIXES

    • Updated the Subscription Tiers backend logic so that when subscribing for a Business Package, the proper subscription gets applied

    • Import Project was failing to parse the KMZ files having xsi:schemsLocation attribution in the document tag…this has been fixed
    • The Tooltips on the DC Field and Array objects of Block Builder did not properly correspond to the field…we have updated this.
  • Release 10.13.0

    10 November 2022

    Slope Grade and Direction is now displayed on Array Details

    PlantPredict Premium subscribers can now easily see the slope grade and direction of all your Arrays by turning on the Advanced Plant Layout within the Slope Design tab of a Map Builder Prediction.  You must zoom into the arrays so that the Array Details are visible.  Please note that this is the prevailing grade of the array as determined by looking at the elevation of the 4 corners of the array.
    Slope Grade and Direction

    Ability to Hide or Display Constraint Labels on your PLP-1000

    We have added a check box control to the PLP-1000 Layers menu to give our PlantPredict Premium users control over whether or not they want to have constraint layers appear on their PLP-1000 PDF downloadable report.

    PLP-1000 Constraint Labels

    Here is a listing of some of the other improvements and enhancements

    • Global Module File Cleanup – We have removed some obsolete module files as we continue to maintain our listing of Global Modules and Inverters
    • Nodal Data File Changes – Within the DC Field Nodal Data Files, we have added 2 additional columns of data:  Cell Temperature at Open Circuit (°C) and Open Circuit DC Voltage at Open Circuit Cell Temperature (V) and we have renamed 2 similar columns for clarity:  Cell Temperature at MPP (°C) – Column AY and Open Circuit DC Voltage at MPP Cell Temperature (V) – Column BA

    • The Prediction Summary 8760 Downloadable report was missing the Plant Net Aux Losses for P75, P90 and P99 results.  This has been fixed

    • When Uploading .KMZ files into Map Builder Predictions, the KMZ Files with xsi:schemaLocation were failing to parse.  We have also fixed this bug
  • Release 10.11.0

    13 October 2022

    More Weather Download improvements

    Clean Power Research Version 3.6 weather files are now available for download using the 1-Click Weather Download feature in PlantPredict (You must have a SolarAnywhere API key and PlantPredict Premium to use this feature).  We also updated our 1-Click Weather Download so that PlantPredict Premium users can download Clean Power Research Version 3.5 weather files in Canada.

    CPR V3.6

    We also fixed some issues with our new NSRDB 1-Click Weather Download functionality that was part of the last release.

        • The Time-Shift on the Quality Check page was not being properly applied when importing a Custom NSRDB weather file
        • Custom NSRDB files will now be imported as Draft-Private weather files, so that you can update the name and use them within your company only.  We do not want these custom weather files listed as part of our Global Database.

    Block Builder Usability Improvements

    Cloning

    When Cloning a Block, Array or Inverter you will now be placed into the newly cloned object after the operation completes.  Previously, you would remain in the object that you had cloned, which did not seem very intuitive.  This would require you to navigate out of the current object and into the newly cloned object to make any changes, which is extra clicks that seemed unnecessary.

    Deleting

    When deleting a Block, Array, Inverter or DC Field you will be taken to the object directly above the object that was deleted.  Previously, you would be taken to the first object, which also did not seem intuitive.  The only exception to this is when deleting the first object, you will then be taken to the object that is now the first object.

    SMA Global Inverter Files for the Sunny Central UP Family have been released in PlantPredict’s Inverter Library

    In collaboration with SMA, we have released the latest SMA Inverter files with OEM review and certification.  These inverter files contain 4 efficiency curves which will lead to more accurate predictions that other what can be achieved in other industry standard yield simulation software.

    SMA Inverters

    BUG FIXES

    • Backside Irradiance and Backside Mismatch were not displayed correctly on the Plant Summary 8760 report – This now has been fixed

    • Fixed the new String Size Project Status so that it is usable now
    • Fixed a bug with the DXF file download functionality in Map Builder so that it is now possible to download very large layouts as DXF files
  • Release 10.10.0

    29 September 2022

    Sub-hourly weather files are now available for download from NSRDB

    Sub-hourly modeling is a very important capability within PlantPredict, and we want our PlantPredict Premium users to be able to do sub-hourly modeling even if they don’t have a SolarAnywhere or SolarGIS subscription.  So, we have updated our NSRDB API integration in order to allow our PlantPredict Premium users to download sub-hourly weather files from the NSRDB.  Simply add a new weather file for your location and click the download button for the NSRDB file format.  This will present you with a choice to download the Standard TMY (60 minute) files or to choose from a Customized Format that includes sub-hourly data

    Sub-Hourly NSRDB Data

    Specify your download options

    Download Options

    Download your sub-hourly data

    Subhourly Data

    Search Libraries by Object ID

    As a minor usability enhancement, you can now search for Modules, Inverters, Weather Files, etc… using the Object ID that you want to use.  If you know the ID, just enter it into the search box to quickly get to the Object you want.

    Search by ID

    BUG FIXES

    • ResultDetails endpoint should return results down to the granularity of the weather file interval – This has been fixed

  • Release 10.9.0

    15 September 2022

    Near Shading Loss Comparison

    As we continue to work on modeling the impacts terrain has on a prediction, one of the loss factors we want to pay special attention to is Near Shading Loss.  For our PlantPredict Premium subscribers, we have added the ability to see Near Shading Loss comparison between predictions in our Prediction Comparison Charting screen.  This will make understanding the impact of Near Shading Loss on your project easier than ever.

    Near Shading Loss Comparison

     

    Company Admin – Available Licenses

    For all our Company Admins out there (Only Available with PlantPredict Premium Business or Enterprise Subscriptions), we appreciate the work you to do administer your company’s users and default values.  We have updated the Company Admin Screen so that you can easily see how many Active Users you have and how many Available Licenses you have remaining.

    Available Licenses

     

    BUG FIXES

    • We fixed the auto formatting of SolarAnywhere TMY3 file formats, so the import process should go smoother now when importing TMY3 files
    • In certain situations, when you opened the Project Library it would appear like all your projects were gone.  A quick refresh would bring them back.  We think that we fixed the issue that was causing your projects from disappearing in the first place.
    • We changed our 3D shading scene processor so that the server is turned off by default.  When you run a 3D shading scene prediction it might take a little longer because the server will need to be started up.
    • Company Level Defaults were being reset when you added a Weather Vendor API Key.  We fixed this so that it does not happen anymore.
  • Release 10.8.0

    01 September 2022

    Quality of Life Improvements!

    Every once in awhile, we have a sprint dedicated to improvements that we call “Quality of Life Improvements”.  These are simple changes that make the user interface work more smoothly and make certain tasks easier in the application.  Here are some of the ways we are making life better for our PlantPredict Users.

    • Library Filters and Sorting stay consistent across the application during a session – When you go into the Weather, Inverter or Module Library and define a filter (i.e. My Weather) or a Sorting (i.e. Rated power highest to lowest), these selections will stay for the duration of your session.  They will even appear for you as you are in a prediction and selecting your weather, inverter or module.  This will reduce the number of clicks when creating multiple predictions and should make the application just work a little better

     

    Filter and Sort

     

    • Multi-Selection Prediction Deleting – Sometimes it is nice to keep your projects clean, and one way to do that is to delete the predictions that you no longer need within your project.  Traditionally, you could do this by deleting them one-by-one.  Now, you will be able to select multiple and delete all of them with the single click of a button.

    Multiple Delete

     

    • Added a Close (“X”) on the Prediction Results screen – When viewing the prediction results, it was not obvious how to return to the actual prediction.  You had to either use the bread crumb trail at the top of the screen, the browser back button, or go all the way back the the Project Library and navigate into your Project and Prediction.  We thought an intuitive Close button (Labeled with a simple “X”) would be helpful.
    • Constraint Setbacks when using Metric UoM are now defaulted to 15.24 Meters instead of 50.  50 Meter setbacks were a little extreme for a default value, so we reduced the default to 15.24, which equals 50 feet when converted to Imperial Measurement.

     

    BUG FIXES

    • We fixed the SolarGIS Timeout Error, which was not happening properly.
  • Release 10.7.0

    18 August 2022

    Roadways are now available in MapBuilder

    We have added a Roadways (Census) layer to our MapBuilder Map Overlays menu.  Now users can turn on this layer and have the software automatically draw constraints around the roadway easement with the click of a button.

    Roadways

     

    We also made the “Handles” a little easier to see when you want to modify a site boundary.

    Handles

    Some other improvements were made to the MapBuilder interface:

      • The snapping feature has been added to the site boundary, so drawing a site boundary is easier now
      • When Calculating DC Capacity on a site with multiple site boundaries, the system will consider each site boundary as an island and maximize the DC accordingly
      • We also refactored our wetland layer to comply with the changes made by the US Fish and Wildlife API

    Promotion Codes

    On the Subscription Page, we added a “Promotion Code” functionality, which can be used to give out Free Trials of PlantPredict Premium.  We plan to try this out at the PVPMC conference coming up next week when we will be giving out Promo Code Cards to Performance Engineers who want to give PlantPredict Premium a try.  Hope to see you there!

    BUG FIXES

    • Loss factor tree – adjusted the chart so that small values (i.e. 1%) look different than 0%
    • Updated Error Codes for when Predictions Fail to make it easier to troubleshoot the reason why a prediction failed.
  • Release 10.6.0

    04 August 2022

    Meet David and Thang at the PVPMC 2022 Conference

    Over the last sprint we have been preparing for the PVPMC conference which is scheduled for August 23rd and 24th in Salt Lake City, Utah.  If you are planning on attending, please seek us out.  The Product Director of PlantPredict (David Spieldenner) and VP of Development Technologies for Terabase Energy (Thang Le) will be there.  If you are not currently a PlantPredict Premium subscriber, we will be handing out Promo Code card that will get you a 30 Day Free Trial.

    PVPMC 2022

     

     

    BUG FIXES

    • When Creating a Module File in PlantPredict an error would occur if you were on the IAM tab of the Module regarding the Sandia Coefficients.  This has been fixed
    • SolarGIS made a change to the TGY API, which was causing the 1-click weather download to error out.  We have corrected this.
  • Release 10.5.0

    21 July 2022

    Batch Prediction Improvements

     

    We returned our attention to our Batch Prediction functionality with this latest release.  Our PlantPredict Premium subscribers will notice that we have added a Secondary Sort to go along with the Primary Sort that was already there.  This is especially useful if you want to organize your results by DC/AC Ratio and GCR%.  Furthermore, the order in which your results are sorted will also be used in the Results Export, so you can simplify your analysis by sorting your results and then exporting them.

    Secondary Sort

    We have also added the ability to export only the prediction summaries for your Batch Prediction result export.  This drastically reduces the size of the file that you are exporting and speeds up the processing of the report generation.  Very large batch predictions would sometimes time out because the results took too long to generate.  Exporting the Summaries should resolve that issue, and in most cases our users are mostly interested in only the summary data.

    Summary Export

     

    DC Field Short Circuit Current now available in Nodal Data Results

    A relatively minor (but very handy) enhancement is that we have added Short Circuit Current to our Nodal Data results.  Nodal Data is a very powerful way to see the details behind the energy prediction results, and now with the Short Circuit Current at each time series interval, you have a little more visibility into your prediction results.

    Turn on or turn off Constraint Labels in Map Builder

    A very common request (especially for those users importing an Anderson Optimization KMZ file) is to hide the constraint labels on the Map builder screen.  Those labels can be helpful, but they can also make your design appear cluttered.  So, we have added an option in the Map Overlays section to turn on or turn off Constraint Labels.

    Constraint Labels

    BUG FIXES

    • SolarGIS PvPlanner one-click weather download was throwing an error at the end of the download.  We have fixed this.
    • SolarGIS default download dataset was not working and this has been fixed.
  • Release 10.4.0

    07 July 2022

    Slope Aware Backtracking

    Coming Soon

    Soon has finally arrived

    For the past several years, in the DC Field section of a Block Builder prediction, we have indicated that modeling your DC Field with trackers that follow the ground slope would be “Coming Soon”….

    Soon has finally arrived!

     

     

    When modeling a DC Field on a sloped terrain, the transposition model will now recognize the North-South Slope (Trackers) and East-West Slope (Fixed Tilt) and adjust the POAI accordingly.  Furthermore, the backtracking algorithm has been updated to recognize the ground slope and adjust accordingly to avoid direct beam shading in the early morning and late evenings when the sun is low on the horizon.  As a result, you can now utilize PlantPredict to understand the impact that ground slope has on the production of your PV Power Plant.

    For our PlantPredict Premium subscribers, we have also updated our Advanced Plant Layout functionality within the Map Builder Slope Design tab so that you can specify if you want to use the traditional Flat Table Orientation or the new Sloped Table Orientation (with Slope aware Backtracking).  You can also specify if you want to use the 2D (fast and accurate) or the 3D (a little slower and slightly more accurate) shading algorithm.Advanced Slope Design

    Ashrae Station Database has been updated

    Ashrae 2021

    We have also purchased and rolled out an updated data set of Ashrae weather station data.  When PlantPredict pulls the nearest Ashrae station, you will be pulling from a 2021 data set.

     

     

    SolarGIS API Integration has been updated

    SolarGISFor Plant Predict Premium customers who are also Solargis API Customers, you can now take advantage of a new and improved site-specific (high spatial resolution) Solargis API, which serves TMY60 (Typical Meteorological Year at 60-minute intervals) or TMY15 (15-minute intervals) using our 1 click weather file download feature.

    Solargis TMY files are calculated using long-term historical time series data (from 1994/1999/2007 to the end of 2021, depending on the regions). The data is also site-specific at upto 250m resolution levels. The TMY data is generated using the latest Solargis model each time the API request is placed (not pre-calculated).

     

    BUG FIXES

    • User Management screen would throw errors when trying to add new users – most (if not all) of the known issues here have been fixed
    • We broke out 3D and 2D predictions into their own queues so that 2D predictions would not be log jammed if a long running 3D prediction was blocking the queue.
    • Maximum slope has been updated to support up to 30 degrees of slope (up from 10 degrees).

  • Release 10.3.0

    09 June 2022

    Short Sprint = Minor Release

    We had a very short sprint this release cycle and only released some back end improvements and a minor bug fix.  Our development team is working on a major release that is planned for the end of this month, which will include Slope Aware Backtracking!  This is a major step forward in PlantPredict’s ability to model terrain and the shading impacts of the terrain.  Stay Tuned!

    BUG FIXES

    • Added a new Project Type for the String Sizing Calculator tool that is currently under development
    • Addressed loophole issue regarding PlantPredict Premium Licensing and API Access
    • Fixed an issue with the Slope Constraints logic where we would get inverse constraint creation when a site was completely surrounded by high slope areas.

  • Release 10.2.0

    20 MAY 2022

    Batch Prediction Improvements!

    We are rolling out a new user interface for our Batch Predictions today, which allows the Batch Prediction functionality to work better and look nicer for our PlantPredict Premium customers.

    Batch Screen Improvements

    Model Choices in Batch

    • Utilize the Uncertainty Analysis to do a P90, P99, P50 or even a P10 analysis for your batch predictions
    • Specify your models (decomposition, transposition, module temperature, etc…) that will be applied to your batch prediction putting you more in control of the results
    • Now you can run multi-year predictions in batch mode.  This makes it easier to see how energy results are impacted by long term degradation when you vary any of our batch variables with your prediction.

    Multi-Year Batch Results

    Analyze North and South Slope separately in 3D Site View

    PlantPredict Premium subscribers can now analyze both North facing and South facing slope separately

    North and South Facing Slope

    New KMZ Layer Upload mode

    There is now a KML/KMZ backdrop mode in the Upload KMZ pop-up window.  This allows a PlantPredict Premium user to be able to upload a KMZ file and create an overlay with the objects in the KMZ.  Clicking on the objects allows the user to define if the object is a site boundary or a site constraint.

    BUG FIXES

    • One-click weather download was not working properly with the CPR API key.  It is now working just fine.
    • Fixed Tilt batch predictions were not computing correctly
    • When popup displays on Mapbuilder, a ‘selection dead zone’ occurs on TOP and RIGHT of popup

    • When setbacks for both Site Boundary and Constraints are ‘0’, building DC islands is compromised

  • Release 10.1.0

    03 MAY 2022

    New Password Policy has been implemented

    With today’s release, we have increased the data security protection of all PlantPredict users by strengthening our password requirements.  All users will need to reset their password as part of this change, so an email is being mailed out to all PlantPredict users with a temporary password that will allow the user to reset their password.

    If you have any trouble logging in please contact PlantPredict support at support@plantpredict.com.

     

    Post Height has been added as a Batch Prediction Variable to Iterate on

    We are going to be expanding the Batch Prediction capabilities of PlantPredict over the next few sprints.  One of the first changes is that we have added post height as a new parameter that can be iterated on.  This allows users to quickly identify the optimal post height for their project

     

    Batch Results

    Specific Yield added to Batch Results Chart and Sort By Parameter

    Users can now choose if they want to see their Batch Prediction results charted by Specific Yield or Plant Net Energy.  Sometimes, users want to prioritize Specific Yield, and that was difficult to do when the only parameter to chart on was Plant Net Energy.

    Measurements appear when drawing Constraints in the Map Builder tool

    When drawing Constraints (Both Area and Linear), the measurements will appear as you draw.  This will allow you to make sure your constraints align with the dimensions of the object that you are trying to model as a constraint.

    Constraint Measurements

     

    BUG FIXES

    • Nighttime Inverter Losses has been removed from the Block Builder Array screen as it was not actually impacting Yield.
    • Backside Irradiance was appearing as negative in the Loss Tree in some situations
  • Release 10.0.0

    21 APR 2022

    Version 10

    Improvements to our Bifacial Model

    With Version 10 we are making your Bifacial Predictions more accurate and making the results easier to understand by adjusting how the Backside Mismatch is affecting Module Irradiance Loss.  In version 9 the Backside Mismatch of a Bifacial module would have an impact on the Module Irradiance Loss.  This was not aligned with how other software such as PVSyst or SolarFarmer works and so it was a source of confusion for our users who were comparing PlantPredict Results with these software.  We also noticed that the impact on Module Irradiance loss was overstated on predictions with very high Backside Mismatch losses (i.e. greater than 20%).

    Furthermore, we are replacing Backside Effective Irradiance in our Loss Factors with Backside Irradiance and Structure Shading Loss.  In Version 9, Backside Irradiance and Structure Shading Loss were bundled together into Backside Effective Irradiance, and we felt that this was not transparent enough.  So, now you can see the Backside Irradiance Gain along with Structure Shading Loss to understand the impact that the structure shading is having on the energy results of your prediction.  More details can be found in our Models and Algorithms section of our website:  https://plantpredict.com/algorithm/irradiance-radiation/#679-2

    Backside Loss Factors

     

    Updates to our GTI DIRINT Model

    With Version 10 we are also making an adjustment to our GTI DIRINT decomposition model to better handle diffuse light at sunrise and at sunset.  For predictions that were using subhourly weather data with Plane of Array Irradiance, we were noticing a spike in production around sunrise and also at sunset.  The changes we made to the GTI DIRINT model will smooth these effects out.  More information can be found in the Models and Algorithms section of our website here:  https://plantpredict.com/algorithm/irradiance-radiation/#disc-model

    3D Shading Model processing time improvement

    Lastly, with Version 10 we are making a change to our 3D Shading algorithm model that will speed up the processing of predictions that use the 3D Shading engine.  We are basically reducing the resolution that the model is using, which has a significant impact on the processing time of the engine, and is not having a significant impact on prediction results.  You may notice a change to your shading loss when running a prediction with 3D shading in version 10 compared to version 9.  You will also notice that the predictions take about 75% less time to run in version 10 over version 9.

    A fresh Meteonorm weather file is now automatically downloaded for your Project Location when you create a Project in PlantPredict or the Terabase Dev Platform

    In order to ensure that there is always at least one weather file available for your Predictions, we are automatically downloading a new Meteonorm weather file in the background when you create a new project in PlantPredict.  Some of our Meteonorm weather files are a little dated, so this will also ensure that you have the latest Meteonorm data ready and available to use for your predictions.

     

    Make sure to look for the Meteonorm weather file with the current date to use the fresh weather file for your Project.

    Updated Integration with Clean Power Research’s SolarAnywhere TGY Unlimited API

    Clean Power Research has updated their API integration to a single API Key, which simplifies setup.  Furthermore, Clean Power Research now offers their SolarAnywhere TGY Unlimited subscribers the ability to automatically generate an API key, and then use that API key in PlantPredict.  When an API key is setup for CPR, you can use the 1-Click Weather Download feature to automatically download up to 200 weather files per year for your company.  This capability is only available PlantPredict Premium subscribers, and you must be a Company Admin in order to update your CPR API Key.  If you would like more information on how to Subscribe to PlantPredict Premium, or how to setup your SolarAnywhere API Key, please contact support@plantpredict and we will gladly help you!

    Prediction Comparison Charting

    When doing a Prediction Comparison, you can now compare multiple predictions using the chart interface.  Simply initiate the Prediction Comparison, and then you will see a tab that is labeled Charts and when you go to this tab you can compare the key performance indicators of those predictions.

    Comparison Chart

     

    Inverter Limitation Loss Charting

    We are planning to add Loss Factors to our charts (for PlantPredict Premium Subscribers ONLY)and we are starting with Inverter Limitation Loss as our first Loss factor.  So, you can see when your inverters are working sub optimally and also visualize the clipping that is occurring in your power plant.

    Inverter Limitation Loss

     

    Other Minor Enhancements

      • Downloaded Weather Files automatically appear as the Selected Weather File when imitating the weather file download from inside a prediction.  This is a minor change that will save you time each time you want to download a new weather file for your prediction.
      • Latitude and Longitude Values now appear as decimal values on the Project Screen.  We have received feedback that the minute level format for Lat/Lon was not helpful, so we changed to Decimal format only when displaying Lat/Lon.
      • You can now initiate a Prediction Clone from within the Prediction Screen.  You used to need to navigate to the Project Screen and then clone the Prediction that you wanted to clone.  That was a couple extra mouse clicks, so we added a Clone link to the top of the Prediction to make this process a little easier.
      • You can now create a Constraint Shape from a Parcel with a click of a mouse button.  Historically, you could only create a Site Boundary, but now the option exists to also create a constraint.  This is handy if you are evaluating multiple parcels in an area and you want an easy way to turn on/off certain parcels.
      • Terrain Slope constraint analysis now supports support values up to 30%.  We used to limit this to 20%, but we received feedback that users would like to evaluate slopes even greater than 20%.

     

    BUG FIXES

    • Users without Company Level Default Road Widths were not able to create Block Builder Predictions because of an error.  We have resolved this.
    • Project/Prediction File imports (.PPP Files) that included Non-Global modules or inverters were failing.  This has also been resolved.
  • Release 9.4.0

    24 FEB 2022

    Multi-Variate Charting

    On the Prediction Results Screen, you are now able to view Chart Data for two Variables at the same time on the same chart.  This increases your analytical ability when reviewing your Prediction Results.  Place a checkmark in 2 of the available Variables to Display and those variables will appear in the chart window.  This works for all time increments

    Multi-Variate Charting

     

     

    BUG FIXES

    Slope Aware Map Builder Predictions

    Our first version of Slope Aware capabilities is being rolled out as part of this release for PlantPredict Premium Subscribers ONLY.  When working with a Map Builder Prediction, you can turn ON the Advanced Slope Aware mode and PlantPredict will determine the prevailing grade of your arrays and utilize that to adjust your shading losses accordingly.

    Slope Aware Predictions

    Update Inverters and/or Modules when Cloning a Project

    When cloning a Project, the wizard will now stop and ask you to review the Inverters and Modules that are used within the Predictions associated with the Project.  You are then given the option to change the Inverters and/or the Modules which will automatically update the DC Field records associated with all the Predictions in the Project.  This will make it easier and quicker than ever to understand how a wholesale change of either Inverter or Module will effect all the predictions in a Project.

    Anderson Optimization KMZ can be imported directly into a Mapbuilder Prediction

    PlantPredict Premium users who are also Anderson Optimization subscribers can take Boundary and Exclusion KMZ files from Anderson Optimization and import them directly into PlantPredict.  This will streamline the integration between these two industry leading cloud based software.

    Anderson Optimization Import

    BUG FIXES

    • Updated many of the references to First Solar and replaced them with PlantPredict by Terabase
    • Updated the Locality Bug that users were facing where PlantPredict could not determine a country for a location
    • We did a Module and Inverter Refresh and Cleanup.  Several newer Modules have been promoted to Global Status and several Older Module and Inverter files have been set to Global Retired.
    • Enabled 2D Shading for Version 8 and Version 9 Predictions when your DC Field has a slope.  There was formerly a validation that prevented this from being possible.  The 2D Slope Shading logic is the same as PlantPredict V7.
  • Release 9.2.0

    27 JAN 2021

    Release 9.2.0 is a relatively minor release for PlantPredict.  The team has some big ticket items we are working on and are not ready to be released yet, so look forward to these features that are in development:  Terabase Dev Platform integration and Slope Aware Predictions.

    For this release we did some cleanup on the Company Administration screen.  We removed the buttons that were needed for the Consent process that we used when we were transitioning to Terabase.  We also worked on our payment processing functionality to address some issues that PlantPredict Premium subscribers had encountered when renewing their subscriptions, so the payment process will work a little smoother as a result of this release.

    Thank you for your continued use of PlantPredict and if you have any trouble or suggestions for improvements, we are happy to hear from you at support@plantpredict.com!

    PlantPredict Premium Subscribers can now download their MapBuilder Layouts as a CAD compatible file (Drawing Exchange Format -DXF File)

     

    Opening your MapBuilder Layout in AutoCAD is as easy as a few button clicks now!  We have updated the Download Data feature in the MapBuilder screen, so that it now opens a modal window where you can choose to download your Layout as a .KMZ or .DXF file.  The .KMZ functionality still works as before; however, when you choose the .DXF format (and desired Output Coordinate System), you will get a .DXF file that can be opened in AutoCAD, Civil 3D or other .DXF compatible applications.
    DXF Download

     

    PlantPredict Premium Business and Enterprise Company Admins ONLY – New Company Level Defaults are available

     

    For our PlantPredict Premium Business and Enterprise customers, standardizing predictions across your company will now be easier than ever!  Company Admins are now able to establish a default: Inverter, Module, Desired DC:AC Ratio, Design Derate, Mounting Type, Setback, N-S and E-W Road Widths, GCR and Azimuth.  Once the Company Defaults are established, all new predictions (both MapBuilder and BlockBuilder) will start with these default values.  This will save your Engineers time on every prediction they create and also enforce design standards at your company.

    Company Defaults

     

    Mark your Favorite Predictions as “Favorites” for easy Navigation

    There is now the ability to indicate up to 5 Favorite Predictions to make them easily accessible from the left navigation pane of PlantPredict.  Click the star near the top of the Prediction to Mark it as your Favorite and then it will be listed under your Favorites on the left hand side

    BUG FIXES

    • Copy and Paste did not work on the Spectral Loss column in the Environmental Conditions Screen.  Now it does.
    • Recent Predictions listing did not work properly for those with multiple accounts on the same computer.
    • Companies with a CPR API key were not able to use it, now they are.
  • Release 9.0.0

    16 DEC 2021

    As we finish out 2021, we will be starting 2022 with a major version release of PlantPredict.  PlantPredict Version 9 is our first major release in over a year, so we are very excited to be making this upgrade, which also coincides with our transition to Terabase Energy.  Below is a summary of the changes that are being released as part of Version 9.0.0.  Please be aware that all new predictions will be run using V9 logic.  You can still run predictions using V8 logic, by setting the Version to 8 in the Prediction Screen prior to running the prediction.  This will allow you to compare the differences between results of V8 prediction logic compared toV9.

    Diffuse IAM

    A new calculation method for the calculation of the Diffuse IAM losses has been implemented. The model has been proposed and validated by Marion from NREL and been extended for the use of the tabular IAM values that are part of the module file. More background can be found in our algorithm section under Diffuse IAM Losses.

    Diffuse IAM Loss Calculation

    Expect IAM losses to be slightly reduced when running a prediction using V9 logic as compared to V8 (up to 0.6% for fixed tilt in areas of a high diffuse fraction) as the former logic was using the ASHRAE parametrization for the diffuse IAM losses.

    .PPP Prediction File import into an existing Project

    An Import Predictions button has been added to the Project screen that allows you to upload a .PPP file and have the predictions contained within that .PPP file added directly to the project that is open.  Historically, when uploading a .PPP file, PlantPredict would create a new project, resulting is potentially duplicated project folders.  That behavior still exists if you upload a .PPP file from the Project Library Screen, if needed.

    Import Prediction

    Weather File names are now editable

    Users can now update the name of the weather files that they create and own.  The name will still default based upon the provider and Lat/Lon; however, if you want to provide a special name to a weather file that you own, you are able to easily over-ride the default name.

    Degradation Rate on muti-year predictions will default from the degradation rate as defined on the Module File

    The module defined degradation rate will be the default value when setting up a multi-year prediction.  The user is still able to over-ride this default if they so choose.  We also allow company administrators to change the default behavior, in the Company Defaults section, if they want to continue using a company wide fixed default degradation rate.

    Most CleanPowerResearch Weather Files will no longer be available as Global Weather files

    Due to a change in licensing terms, PlantPredict will no longer make certain CPR weather files available  as Global weather files to all users.  We are currently working with CPR to enhance our integration benefits for our PlantPredict Premium Subscribers who also have a SolarAnywhere subscription.  More to come on that in future release notes.  There will still be around 30 CPR weather files that are already considered SolarAnywhere Public weather files, which will still remain as Global Weather Files in PlantPredict.

    BUG FIXES

    • Fixed holes in the mesh of the 3D Site view where elevation points were missing.
  • Release 8.27.0

    18 NOV 2021

    With this release we carried forward the Sort By logic (that we implemented in the Libraries last release) into the Inverter and Module selection screens within the prediction.  This makes it easier to find the exact Inverter or Module file that you are looking for

    Sort By

    We also changed the source of elevation points in our 3D Site View to use ESRI ArcGIS data instead of Google Earth.  We hope that you will find that the data provided by ESRI is faster to render and follows the terrain better than what Google Earth was providing.

    Powered by Esri

    BUG FIXES

    • Performance Improvement for Super Admins – Caching Company Values
    • Multi-Year predictions used to throw an error when using Locked Weather Files.  We fixed this.
    • Fixed a small typo in the DC Field loss section in the Map Builder screen.  Light Induced Deg. is spelled correctly now.
  • Release 8.26.0

    04 NOV 2021

    PlantPredict Premium Users can now automatically import monthly Albedo values for their specific project location (from NSRDB) with the click of a button!

    Import NSRDB Albedo

    These location specific Albedo Values help you get more accurate results when modeling Bifacial modules, which can help you better understand the value of your solar assets.  The Monthly Parameters table is located inside the Environmental Conditions screen inside your Prediction.  Simply click on the Import NSRDB Albedo button and PlantPredict will pull in the monthly Albedo values from the NSRDB API.

    We also introduced a new Sort By function inside our Module and Inverter Library screens.  This will make finding the Module or Inverter File, that you are looking for, easier.

    Today begins a new beginning for PlantPredict as we transition to Terabase Energy 

     

    As part of the transition, we have been seeking consent from all PlantPredict users to transfer your data to Terabase Energy.  If you provided that consent, then your account and data will remain unaffected throughout this transition.  If you declined consent, or did not provide any response at all, your user account and private data will be removed from the system.  First Solar is maintaining a backup of the non-consenting users and PlantPredict support can work with First Solar to get exported versions of your Projects, Predictions, Weather Files, Module Files and Inverter Files if you did not consent and still want your data.

    Any questions or inquiries, send an email to support@plantpredict.com

    There is a new Terms of Use

    All Users logging in after the transition to Terabase has happened will be prompted with the new Terabase/PlantPredict Terms of Use.  You must accept these Terms of Use to continue using PlantPredict.  A full .PDF Version of the Terms of Use is available at all times from within the Resources page in PlantPredict.

    Terms of Use

    We are very excited about this transition and look forward to serving you better from within our new Terabase home.  Terabase offers a large suite of digital products and services, which we plan to integrate with and create more value than ever before for our customers and subscribers.

    Quality Check is now available when doing a one-click weather download

     

    We have been focusing on improving our Weather Import features for PlantPredict Premium subscribers.  Last release we introduced Solcast as a new weather data provider.  This release we incorporated the Quality Check feature when using the 1-click weather import.  Certain places around the world have time zones that don’t always align with our weather providers.  You now have a chance to review the weather data and apply a time shift to ensure that the weather data you are importing aligns with the solar time zone at the location you are modeling.  This quality check has been a part of the weather file upload for a long time, so we just implemented it in the 1-click weather download process, since it is proven to work very well.

    After the weather data has downloaded, you are taken to a Quality Check screen to review and shift data if needed.

    Quality Check

     

    We also added Map Data to the .PPP Project and Predict Export and Import process.  This makes .PPP Files more complete.

    BUG FIXES

    • Fixed header row styling when importing weather. Previously, the header was shown incorrectly and over the top of data
    • Within MapBuilder, saving the prediction would fail if a constraint was selected that had no label.
  • Release 8.22.0

    Today we launched our Downloadable Layout Document, the PLP-1000, to our Map Builder tool.  This will allow PlantPredict Premium users to generate an engineering grade document that they can share with their project stakeholders and colleagues.

    We also greatly enhanced our layout capabilities with the introduction of our Advanced Layout DC Design functionality, which now allows you to select arrays so that you can delete, duplicate or move the DC field around on your map.  Fill in tight areas of your boundary, or remove the arrays from the portion of the boundary that will not have solar.  Find these functions on the toolbar in the Map Builder.

    Following up on our 3D Site View release last month, we also implemented a Cut/Fill Capability into the Map Builder Tool.  Flatten a portion of your site and find out how much dirt will need to be moved to do so.

    9 MARCH 2018

    • Fixed bug causing sun icon on loading screen to not work properly
    • Fixed bug with Map Builder causing energy predictions to be incorrect*
    • Cloud service operating system upgraded

     

    *On February 22, 2018, an issue was identified with the PlantPredict Map Builder that caused shading losses to be understated and predicted energy to be overstated. The issue was rectified with Release 6.0.0 on 3/9/2018. The issue is confined to Map Builder predictions created and run prior to Release 6.0.0. Because shading losses are generally higher for horizontal trackers, especially when true-tracking, such predictions will be most significantly affected.

    Users with affected predictions can remedy their predictions in a couple ways. First, rerunning Map Builder predictions using version logic 6.0.0 will resolve the issue. Alternatively, users can convert Map Builder predictions into a Block Builder predictions while maintaining version logic 5 or earlier. Either method is equally valid and will successfully resolve the issue. Upon rerunning, users should expect to see an increase in shading losses and decrease in energy.
