PVTwin, unique solar system

A ZEN PV Twin system is the unique combination of photovoltaic cells with a solar thermal absorber, forming one device that converts solar radiation into electricity and heat simultaneously. Medio 2008 the PWTwin system was integrated in the total ZEN Renewabels portfolio.  The first projects are allready under construction.

The excess heat generated in the PV cells is removed and converted into useful thermal energy. As a result, PVT absorbers generate 43%  more solar energy per square meter than a combination of separate photovoltaic panels and solar thermal collectors In addition, the integration of the two functions in one device leads to large potential savings in material use and in production, balance-of-system and installation costs. This also gives PVT an aesthetic advantage: only one building element is required to produce both forms of solar energy.
