How it makes an impact: With PlantPredict, you can efficiently conduct site capacity assessments and identify locations that meet clients’ requirements.

Below is a list of things you can do in PlantPredict:

  • Create site boundaries by either drawing them on a map, selecting parcels, or uploading a KMZ file.
  • Add wetland buffers and FEMA flood zones to identify unusable areas.
  • Check the proximity of transmission lines and substations to the project site.
  • Check for major utility crossings on site.
  • Evaluate areas that may be too steep for installing solar panels.

This rapid capacity assessment in PlantPredict can dramatically save engineering hours and boost portfolio ROI.

PV Energy Simulation Report

What is it?: After completing an energy prediction in Plant Predict, you can download the Plant Summary as a PDF and the 8760 report (which details energy generation over the 8760 hours of a year) as an Excel file.

How it makes an impact: The Summary Report and the 8760 Report provide stakeholders with detailed assessments of both inputs and results. The extensive information included will aid in enhancing bankability efforts. Additionally, these reports are beneficial as they validate design choices and reduce risks early in the project.

Design Pro: Layout Optimization

What is it?: Design Pro is the PlantPredict Pro module used to efficiently optimize large scale PV power plants using financial metrics. With DesignPro you can create site layout scenarios, predict energy yields, generate a Bill of Quantities, estimate EPC cost, and conduct LCOE analysis through multi-year cash flows—all within a collaborative environment.

How it makes an impact: Design Pro delivers more in depth cost and financial analysis  for utility-scale site designs across multiple design scenarios, thus facilitating design optimization using financial metrics. You should utilize Design Pro after you screen sites in PlantPredict. In Design Pro, you can collaborate with other team members and also download KML file once the design is established. 

Advanced Financial Estimates

What is it?: Levelized Cost of Energy (LCOE) estimates the total cost per unit of electricity generated by a solar project over the course of its lifetime. Once you finalize your model Design Pro, you can generate LCOE and other financial estimates assicated with your Utility-Scale Solar Project. 

How it makes an impact?: These advanced financial estimates offer a clear picture of a project’s financial outlook, giving developers and stakeholders the insights they need before moving ahead with execution. By using Design Pro, a variety of important financial reports and outputs are produced:

  • Bill of Quantity (BoQ)
  • Engineering, Procurement, and Construction (EPC) Costs
  • Financial Reports
  • Internal Rate of Return (IRR)
  • Levelized Cost of Energy (LCOE)
  • Net Present Value (NPV)

Among these, metrics like LCOE, IRR, and NPV play a central role. These figures help investors and lenders evaluate a project’s financial health, its potential for profitability, and the risks involved. With reliable data in hand, it’s easier to compare different options and make confident decisions when it comes to securing financing.

Batch Processing & Scenario Analysis using Performance API

What is it?: PlantPredict provides efficient large batch simulation processing through both its user interface and its powerful Performance API (Application Programming Interface). While batch predictions can be created directly in the UI, the API takes this further by allowing users to programmatically perform nearly everything that can be done manually. PlantPredict also provides an open-source Python SDK, making it easy for developers to build solutions and automate processes at scale. This approach is perfect for portfolio-sized projects and for site selection opportunities.

How it makes an impact: While batch predictions can be created directly in the UI, API unlocks a much broader capability of automating tasks in PlantPredict. This enables engineers to run multiple configurations, compare results, and integrate modeling into custom analytics dashboards in minutes, rather than days.

Terrain Pro: Earthwork Analysis

What is it?: Terrain Pro is a powerful earthwork modeling tool for solar projects that calculates bank cut and fill volumes by taking into consideration existing contours and mounting specifications. 

How it makes an impact: Earthwork is a significant task in a utility-scale solar project, and Terrain Pro provides realistic cut-fill estimates early in the process. This leads to cost savings and prevents construction surprises later on. Terrain Pro features built-in configuration for terrain-following trackers, including Horizon, OmniTrack, and DuraTrack.

In addition to earthwork calculations, Terrain Pro offers the following features:

  • Earthwork Heatmap
  • Cut/Fill Map
  • Existing Surface Heatmap
  • Proposed Surface Heatmap
  • Pile Visualization
  • Rack Profiles  

Voltage Pro: String Length Maximization

What is it?: Voltage Pro is designed to maximize string lengths in utility-scale solar projects by providing simulation-based string sizing calculations through advanced modeling techniques instead of simple linear calculations using module datasheet information.

How it makes an impact: Voltage Pro addresses a significant gap in the solar industry by providing precise string sizing, incorporating appropriate safety factors, and utilizing over 20 years of weather data. This methodology helps to move away from the overly cautious strategies that often lead to lost revenue.

3D Shade Modeling and 3D Terrain Visualizer

What is it?: The 3D shade modeling tool is an interactive visualization tool that simulates shading impact and terrain features in realistic 3D environments within PlantPredict. It replicates shading from terrain and array configurations to help make correct design decisions.

How it makes an impact: 3D shade modeling plays a crucial role in improving yield accuracy for modeling and layout planning. This approach considers real-world factors, such as obstructions, slope geometry, and solar variations over time, which helps bridge the divide between flat 2D assumptions and the actual site conditions. The result? A more precise outcome that can significantly affect project economics by preventing expensive errors throughout a project’s duration.

Soiling Analysis

What is it?: Soiling analysis is a modeling component of PlantPredict that simulates loss of efficiency due to dust, pollen, sand, and pollution based on environmental data, wind speed, and regional cleaning cycles. PlantPredict integrates with industry-leading soiling models of PVRADAR and Fracsun CLEO to import site-specific soiling factors.

How it makes an impact: Traditionally, soiling loss is calculated at 2% of total yield each month, based on an average derived over a specific period. However, this 2% figure does not provide an accurate basis for strategizing cleaning efforts or maximizing their benefits. 

Therefore, conducting a precise soiling analysis can enhance yield predictions by taking into account real-world soiling data, which can, in turn, help optimize cleaning schedules.

Top Benefits of PlantPredict
