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. Seven essential characteristics related to initial and long-term PV module performance are combined to create the PSI Rating:
These ratings allow you to make comparisons when analyzing PV modules and help you select the optimal PV module.
Before using the PSI Ratings, you should subscribe to our email list to receive important updates from the Principal Solar Institute.
Here are the PSI Ratings for modules from LS Industrial Systems, calculated based on initial performance test data. If you don’t see a solar module that you are considering, contact us and we will try to add it.
