What is the difference between solar thermal and PV systems?
As previously mentioned, Solar Panel PV systems use energy from the sun to generate electricity with roof mounted modules. Solar Thermal employs roof mounted collectors to absorb energy from the sun. These collectors are usually connected to the lower coil of a twin-coil cylinder via a sealed circuit containing a special glycol/water solution. The pump in the system circulates the heated fluid from the collector to the cylinder, where the stored water is heated for use in the home.
