Financing for a solar array is often difficult to obtain and buying outright is difficult for many homeowners, so why not community solar asks WREF2012.
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.
Students in the South Bronx are advancing research in the synergy between green roofs and PV arrays.
