Heat and electricity from one module

Photovoltaic and solar thermal energy Strom und Warmea us einemM odul Producing warm water with collectors is an ecologically sensible and viable measure in order to spare resources of fossil fuel and your wallet. So far the house owner had to decide for a photovoltaic system and a separate solar thermal system for the warm water production, which meant that always a portion of the roof area could not produce electricity. It always had to be pondered between the area for electric power production and the area for warm water production. Now the only thing to be calculated is which portion of the...

Higher returns due to cooling A welcome side effect: The heat transfer to the solar liquid automatically cools the modules as the heat is deducted to the warm water reservoir. This lets the temperature of the photovoltaic cells decline. Due to this process the electric energy output increases because cool modules do have a higher efficiency factor than warm modules. Cooling the modules therefore pays off in two ways: The production of sun heated water simultaneously increases the electric efficiency factor of the solar plant. How much it rises due to the cooling effect depends on how much of...

Optically the 2Power modules do not look different than conventional photovoltaic systems. They are same as flat and have the same dimensions and surface. But they achieve much more: They deliver electricity and heat. The roof area becomes tidier as only one type of collector needs to be installed. Therefore untidy roof areas with different types of collectors for heat and electricity production are a matter of the past. 2Power modules can be applied anywhere where an inclined area is available. As a basic principle: The higher the warm water requirements of a building in the summer the larger...
