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.
