Vacuum solar collectors

Vacuum solar collectors have a higher efficiency level in autumn and winter compared to standard flat surface collectors; these collectors efficiency is lower in summertime. Vacuum collectors are particularly suitable for heating integration of low temperature systems such as floor and wall heating systems or for high temperatures. Vacuum collectors feature is that they are made of vacuum glass tubes with a high efficiency selective coating; the central part of these tubes is entirely copper. The basic characteristic of these panels is that they have a curved transparent absorbent surface allowing collectors which are not perfectly positioned southwards to have a good output.
SUNERG Vacuum collectors are also tested by qualified institutes.
