Solar collector
The SOLARNOR collector is consisting of two twin-wall sheets of high temperature resistant plastics, fixed in an aluminium frame. The solar radiation is converted to heat in the absorber sheet. Pure water is trickling through a channel structure, absorbs the heat which is deposited in the absorber and carries the heat to a heat store.
The solar system is operating automatically by means of a pump controller. It is a drain-back system. In periods without possibility for solar harvesting, the controller stops the circulation and the liquid in the collectors is draining within few minutes.
Certification
The collector is certificated by the German Institute for "Normung" DIN with the DIN approval. A life cycle assessment study by PE Product Engineering GmbH reveals that the 100 % recyclable solar collector is significantly more environmentally friendly than conventional collectors.
