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.
