There are two manufacturers of solar thermal equipment:
Norsk Solfangerproduksjon AS
Aventa AS has a long experience using polymer materials in solar thermal applications. Through a collaboration with Chevron Phillips Chemicals and Kaysersberg Plastics, Aventa has developed manufacturing technology for solar collectors crafted in advanced plastic materials. During 2012, Aventa AS completed it’s new facility for the production of solar collectors. The facility automatizes an important part of the solar collector production; namely joining end-caps and absorbers (the solar collector’s active core). This is done by using an infrared welding method, which creates a high and stabile quality. The Aventa facility has an annual design capacity of approximately 40 000 sqm solar collector area.
Norsk Solfangerproduksjon AS (ASV Solar) is producing solar collectors from aluminium. The solar collectors is not pressurised, and drains the water in the solar collector circuit every time the pump stops.
All in all, there are about 25 suppliers of solar thermal systems in Norway, and a large portion of the installations are imported.
