Advanced Input Options: Key I-V Points

If the user has data from module performance testing conducted according to the IEC 61853-1 standard, or less comprehensive module performance data formatted similarly, the “Key IV Points” input option is recommended. The benefit of this option is that if the user provides performance data at multiple temperatures and irradiances, the temperature coefficients and relative efficiencies will be automatically calculated, respectively. The only required input is a row of performance data at 25⁰C, 1000 W/m2. However, if this is the only data available to the user, the “Basic Data” input option is recommended.


Click “Add New Module”, and then select “Enter Key I-V Points” when the modal appears.



In order to add data manually, click “Add Row” to add data at a new irradiance (within a temperature tab). Add data at a different temperature by adding a temperature tab to the data matrix.



Fill in all of the electrical characteristics in each row. When sufficient data is supplied at a given temperature, the relative efficiencies for each irradiance will calculate automatically. Similarly, when data is provided at 1000 W/m2 for multiple temperatures, the temperature coefficients will calculate automatically.



Alternatively, the user can download the .xlsx template and upload it to automatically populate the Key I-V Points grid.



Clicking “continue” will land the user on the main module file creation page documented in the guide for “Generating a Module File From Basic Data”. The “Electrical Characteristics at STC”, “Temperature Coefficients” and table of relative efficiencies in the “Advanced Tuning” section will be prepopulated with any data processed from the Key I-V Points page.
