Your Guide to Monthly Snow Loss Values from NREL

Snow on solar panels can decrease the amount of energy they produce throughout the year. Yet it can be difficult to know how to account for these snow losses because of variation across locations and system designs. Data from NREL can help solar contractors determine the appropriate snow loss factor.
