What is the difference between a) a PV (Solar) Module, and b) a solar thermal collector of a Solar Water Heater?

  • A PV (Solar) Module is made up of an array of photovoltaic (solar) cells, embedded between a multi-layer back sheet and a special high transparency glass. The PV cells form the basis of the technology that allows the conversion of radiation energy to electrical energy.
  • A solar thermal collector of a Solar Water Heater in its simplest form can be a black plastic pipe filled with water and exposed to the sun. Today sophisticated collectors however, consist of an efficient multiflow absorber containing the liquid. They are covered by special glass with a minimum radiation transmittance of 94% and are well insulated.
