The thermal energy generated by a thermo-photovoltaic plant realized with FOTOTHERM® modules can be used to soddisfy different needs, such as a partial or complete integration of the heating system for:

  • Swimming pools
  • Underfloor heating (low temperature heating)
  • Hot water
  • Process indutrial systems

A system made with FOTOTHERM® modules provides at the same time the possibility to recover the heat by cooling the photovoltaic cells and to increase the efficiency of the electrical conversion.

system with boiler

Operating principle: during the day the recycling of the fluid provides the cooling of FOTOTHERM® modules to mantain an optimum working temperature; the heat absorbed will be used to heat the hot water tank of the heating system a or will be stored in a solar hot water tank.

system with radiant panels

Operating principle: during the day the recycling of the fluid provides the cooling of  FOTOTHERM® modules to mantain an optimum working temperature; the heat absorbed will be used to integrate a radiant panel system (or any kind of low temperature heating) or will be stored in a solar hot water tank.

Operating principle: this kind of plant represents the union of the two previous schemas. The heat obtained by cooling FOTOTHERM® modules will be used for the integration with an hot water tank and a radiant panel system.

A controller thorugh two heat exchangers and a pump, manages the heating of the water in the tank and of the water thorugh the return manifold of the radiant panel system. In case the temperatures reached by the system aren’t sufficient, the plant will be helped by the heat generator. The surplus of energy will be stored in the solar tank.

When the temperature of the FOTOTHERM® modules is lower than the temperature of the solar tank, the controller drives a three-way valve to exclude modules from the circuit and to exploit the stored thermal energy. The cold water will be pre-heat by the exchanger before go into the hot water tank to exploit the thermal energy even in case of low temperature.
