Combined collector

From left to right: solar collector, photovoltaic and both in one. The combined colletor has a so good thermal efficiency, that hot water can be produced without heat pump.

Other photovoltaic heat combinations produce only warmth at a low temperature level, where a heat pump brings it up to 50 degree Celsius.
Photovoltaic - Electric power direct from light Photovoltaic - Electric power direct from light
Even a far north situated industrial nation like Germany could produce a big part of the needed energy by the roofs of the houses. Photovoltaic has much potential.


Photovoltaic and heat combined Photovoltaic and heat combined
Cogeneration of electric power and heat from one modul. Optimal utilization of roofs by combined production of electric power and heat on the same area.
