SolarAnywhere PV Power Maps provide a unique view of national solar resource availability as illustrated by the monthly energy output of a nominal 1 kW 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.
Anyone interested in PV can quickly gauge the energy generation potential of a new PV system, or benchmark performance of an installed system based on location. Simply multiply the power output indicated on the PV Power Map by a project’s capacity, in kW, to calculate total estimated power output for the month.
The PV Power Maps are created using Clean Power Research simulation tools and SolarAnywhere irradiance data, with visualization and mapping provided by GeoModel Solar. You can also view the maps each month on page eight in the Solar Today magazine, or online at Solar Today.

* The PV Power Map is created with power output estimates generated by SolarAnywhere. The calculations are based on a PV system with a total 1-kW nameplate rating that is configured as five 200-watt PV panels with a 1.5-kW inverter; fixed, south-facing panels with 30 degree tilt; no shading; panel PVUSA Test Conditions rating of 178 watts; and inverter efficiency of 95.5 percent.
