The Principal Solar Institute (PSI), an online reference center and resource guide for the commercial and utility-scale solar market, has rolled out PSI PV Module Rating, a rating system designed to provide unbiased, comprehensive analysis and comparison of photovoltaic modules.
‘Until now, there was no accepted standard for comparing the critical characteristics of PV modules between different manufacturers, or even across a single product line,’ says Matthew A. Thompson, executive director of PSI.Â
The rating is a comparative number that can be used with pricing information, providing power plant designers and buyers with a consistent basis for choosing a particular PV module, the company explains.
