PV Generation Potential for May and June

The PV Power Map is a report of national solar resource availability as illustrated by the monthly energy output of a nominal 1-kilowatt (kW) photovoltaic (PV) system by location. The May and June maps illustrate the Great Lakes dampening effect commonly seen in warmer months. By dampening cloud formation, the Great Lakes’ cold water results in greater solar potential than other regions, such as the Eastern seaboard.
