The Principal Solar Institute Module 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. Seven essential characteristics related to initial and long-term PV module performance are combined to create the PSI Rating:

Actual Tested Maximum Power vs. Advertised
Temperature Coefficient at Maximum Power
Power at Low Irradiance to Power at High Irradiance Ratio
Normal Operating Cell Temperature (NOCT)
Total Area Efficiency
Negative Power Tolerance
Annual Power Reduction

These ratings allow you to make comparisons when analyzing PV modules and help you select the optimal PV module.
