Customized PAN file

In PVsyst, an industry standard modeling program for predicting PV project performance, PAN files model irradiance- and temperature-dependent behavior of PV modules.

Module datasheet specifications can be used to generate a functional PAN file but may not define all module performance parameters sufficiently for the full range of potential irradiance and temperature conditions. 

TDSI estimates these conditions using guidelines traceable to International Electro technical Commission (IEC)   to provide more accurate modeling inputs, similar like Lab results with negligible RMSE.

Measured vs. Modeled – Validating TDSI’s PAN Files

Results from one of the power plant outdoor facility at Bap, Rajasthan were used to assess the accuracy of TDSI’s PAN files. To validate these measurements, NREL-NSRDB parameters and weather data were entered into PVsyst and the modeled results were compared to the total measured energy generation for a 12-month period. In the example here, the expected power output generated by the model based on TDSI’s  PAN file was within 0.5% of the measured field results
