Tubular solar thermal collector
SUNERG SOLAR
surface collectors; the efficiency of these collectors is lower than flat surface systems in summer. Vacuum collectors are particularly suitable to integrated with low temperature room central heating like wall or floor systems or also for high temperature. The characteristic of vacuum collectors is that they are made of vacuum glass tubes with a high efficiency selective coating; the central part of these tubes’s is entirely of copper.
The basic characteristic of these panels is that they have a curved transparent absorbent surface that allows collectors that are not positioned perfectly towards south to offer the same results as if they were.
