Flat-plate solar collector TS

Thermosolar TS 300 solar collector technical data (hungarian):
High efficiency, flat plate collector with a long lifespan. The high efficiency is due to the nickel-pigmented aluminum-oxide selective coating on the absorbing plate which is applied by galvanization, the long life is achieved by corrosion resistant structural materials and the perfectly sealed, deep drawn housing. The internals are made with coil tubing, therefore the collector should only be used in a pump system.
~800-1100 kWh
