A detailed comparison between solar thermal and solar PV.
An Apricus ETC30 collector has 2kW peak output for 4.4m² collector, operating at 60% – 70% efficiency at domestic hot water temperatures. This compares to 2kWp photovoltaic (PV) solar system covering 13m² of roof and operating at up to 20% efficiency. The very high energy output to area of solar thermal system is important as […]
