The Principal Solar Institute Manufacturer Ratings
The Principal Solar Institute’s scientifically designed and certified combination of tests and performance standards provide an unbiased, comprehensive rating system – the PSI PV module rating. PSI Ratings corresponds to the predicted 25-year Lifetime Energy Production (LEP) of each PV module. These ratings allow you to make comparisons when analyzing PV modules and help you select the optimal PV module. Learn more about the PSI Ratings and how to use them.
