New PV Rating System Models Real-World Test Conditions
Compared to STC, which uses a constant light intensity at a fixed temperature, PSI models daily variations in light and temperature, as well as five other factors, to calculate total expected energy production over a module’s 25-year lifetime. Ratings for 500 modules are available on PSI’s website, with 10,000 more available upon request.
