Definitions
- the solar panel is made of a plate -bearing substrate embedded in the frame. There is an electrode, placed on the plate substrate, on which are formed photovoltaic cells made of semiconductor elements based on silicon.
- the semiconductor elements lie under a transparent covering layer, e.g. made of glass with an anti-reflective coating.
- the device for solar photovoltaic panels waste heat management includes at least one absorber, which is arranged on the back side of at least one photovoltaic panel, to absorb waste heat.
- the absorber is arranged under solar photovoltaic panel in order not to limit the solar radiation incident on photovoltaic elements.
- At least one heat exchanger is connected to the absorber. This exchanger is connected into the primary circuit of the heat pump for the active consumption of the waste heat from the absorber. Removal of waste heat positively affects the efficiency of the photovoltaic elements in the electricity production.
- the heat exchanger is connected into the primary circuit to a heat pump, which transports heat from the solar panel for further processing. It means that the waste heat is not radiated into surroundings without proper use.
- at least one Peltier cell is connected to the absorber. This cell produces electrical energy thanks to different temperatures while the Peltier cell is flat and has heating and cooling side.
- Fig. 3 shows airflow below the solar panels on a sloping roof.
- the capacity of the storage 12 is increased according to the number of solar panels 2 and with this related size of the device 1.
