What is the difference between solar thermal energy and photovoltaics ?

Category: Solar energy
  • In solar thermal energy, collectors convert solar radiation into heat, which is transferred through a water-glycol circuit to a hot water or buffer tank.
  • In photovoltaic modules, solar radiation is converted into electrical voltage, which is fed into the building’s power grid through an inverter.
  • Photovoltaic power can be converted into heat by Power to heat modules like the tubra®-eTherm. It can also be stored in buffer tanks and used for heat applications.
