The collector has the job of turning solar radiation into heat at all times of the year and not only in direct sunlight. There are two different types of solar thermal collector, flat plate collectors and evacuated tube.
Consolar offers industry leading versions of each type of collector, optimised not only for performance but also for appearance and to minimise environmental impact during production. Special consideration is given to dealing with possible summer overheating (idling).
PLANO 27 Flat Plate Solar Collectors
Flat plate collectors look like large windows. Behind the glass pane is what is known as a selective absorber. The highly selective lamination converts significantly more solar radiation to heat than would a simple lamination, resulting in higher energy savings especially in autumn, winter and spring.
TUBO 12 Evacuated Tube Solar Collectors
Evacuated tube collectors consist of glass tubes in which the solar radiation is converted into heat. Mirroring behind the tubes concentrates the suns rays. The vacuum in the tubes allows almost no heat to escape and, because of this, they deliver more heat in spring, autumn and winter than flat plates.
It is important with both types of collector that the components are protected from damage during idling periods in the summer, so that the antifreeze/solar fluid has a longer life. This is only possible with collectors which use the very latest developments in solar technology, like the Tubo and the Plano, in their pipework design enabling the collector to evacuate effectively durring idling, or stagnated, conditions.
