Panou solar KTU 6R2
Parameters and specification
Vacuum insulation in glass tubes. Two concentric glass tubes are used, with vacuum between them. The ends of the tubes are sealed so the vacuum is guaranteed for a long time. Vacuum surrounding the absorber is a perfect insulation, minimizing heat losses in a similar way like a vacuum flask does. Thanks to that, nor the tiniest heat gain from cloudy skies gets lost and warms up the fluid in the solar collector.
