SPF Institute for Solar Technology products

Solar thermal collectors and photovoltaic modules are normally covered by glass sheets as a protec- tion against weathering effects, as insulation or re- inforcing element. The efficiency of these products is significantly dependent on the quality of the glazing, because all solar radiation has to be trans- mitted through the glazing before its transformation to thermal or electrical energy.

The "Concise Cycle Test" method (CCT) is a special dynamic method developed at the SPF institute for the testing of solar combi-systems and heat storages.
