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.

PV Generation Potential for April

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. This issue highlights the difference in real-time production when compared to annual averages. The first map illustrates total estimated power output for the month of April 2012. The second shows the average monthly PV power output in 2011.

PV Generation Potential for March

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. This issue contains two maps: one generated using SolarAnywhere’s satellite time-series irradiance data, and the other using National Renewable Energy Laboratory Typical Meteorological Year (TMY3) data. Comparing these two maps highlights why TMY3 data are not recommended to predict short-term performance.

PV Generation Potential for January and February

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. Comparing monthly maps makes it possible to see how irradiance and associated PV system power output vary over time from region to region, often with unexpected results. For example, compare January and February solar resource availability on the eastern seaboard with the Gulf Coast.

PV Generation Potential for November and December

The PV Power Map is a monthly report of national irradiance levels as illustrated by solar power potential. Comparing November and December 2011, December shows slightly higher power production along the West Coast, reflecting the relatively mild, clear weather the region experienced that month.
