The Institute for Solar Energy Research in Hameln (ISFH) has carried out an efficiency test and compared a CSW welded absorber strip to a lasered absorber.

This test highlights that a CSW absorber made using 0.3 mm thick sheet aluminum is just as efficient as a lasered absorber with 0.2 mm thick sheet copper. The aluminum absorbers currently on the market are made using 0.4 - 0.5 mm thick sheet metal in order to achieve the same efficiency as copper absorbers.

The use of the CSW process is also a plus in terms of the ecology, economics and aesthetics of absorber technology.

We deliver absorbers to our customers that have a completely smooth surface, consume less material and energy and are more efficient than other products that have been available until now.

 

Our absorbers are, of course, heat sealed within a protective film. This ensures that the absorber is protected from scratches during transport and installation in the collector, guaranteeing the best possible product quality on delivery to the customer.
