Solar Photovoltaic (PV)
Solar cells, also called photovoltaic (PV) cells by scientists, convert sunlight directly into electricity. PV gets its name from the process of converting light (photons) to electricity (voltage), which is called the PV effect. Learn more from the National Renewable Energy Laboratory (NREL).
Solar PV can be installed on rooftops or on ground mounted/free standing structures. Typically for rooftops, the panels can be installed flush with the roof surface, reducing the visible profile of the panels.
Solar Thermal
Solar thermal systems use the sun to heat either water or a heat-transfer fluid in the collector, which is then used to provide hot water for a home or building. Learn more from the U.S. Department of Energy.
