The Triple Solar heat pump panel has been extensively tested at the prestigious University of Stuttgart, at the IGTE department. In summary, the panel was tested for yield, construction, wind load and snow load. The quality of the production process has also been inspected. Solar Keymark indicates that every product that leaves our factory always has the same quality.
In 2009, and again in 2016 and 2017, the Triple Solar heat pump panel was tested by TNO and certified as the panel that has the best properties to act as an energy source for the brine / water heat pump.
TNO is the leading independent knowledge Institute in the Netherlands
The Triple Solar® system has a declaration of equivalence, which shows that the Triple Solar heat pump panels, together with the heat pump (specifically from the NIBE brand) as a source, perform very well according to the existing standards in the Building Decree.
