“In the winter, during days when there was no sun at all, the water temperature was 40 degrees Celsius, while the thermometer is situated about 10 metres from the system, that is where the temperature is several degrees lower than the temperature in the water tank.

I have an acquaintance who is working on the maintenance of solar systems. When I told him that I do not need to touch anything in regard to the solar collector or the water tank, he cannot believe it that there is a system that does not require maintenance.

At home we also have an old water coil tank connected to a boiler on coal and wood. In our case, the water heating from the solar collector provides higher temperature and better efficiency levels than the water tank connected to the boiler.”

The systems COMPACT comprise a solar panel, a water tank and a stand in one whole unit. They are the result of long years of developments run by Advanced Solar Technology scientists in close cooperation with international research centres. The solar systems consist of a highly efficient solar collector and a corrosion resistant water tank. The absorber and the pipe connections are made of copper. The system is completely sealed. The heat-carrying agent is ethanol, which guarantees reliable protection from freezing, while at the same time there is no need of changing or refilling the ethanol fluid. The solar collector works via gravitational pressure - no circulation pump is needed, and thus the energy consumption is practically zero.
