Components of a typical flat plate solar collector:

Transparent Cover

Super white 3.2mm thickness toughened glass makes over 92% solar energy can go through. 

Absorber

It is made of 0.4mm thickness thin aluminum sheet that is coated with a highly selective blue titanium material features extremely efficient at absorbing sunlight and transforming it into usable heat. Furthermore the aluminum sheet is laser welded to the cooper riser tubes.

Insulation sheathing

The insulation sheathing do a great job on preventing the heat loss from the sides and back of collector, it is made of light weight fiber glass in 35-50mm thickness and 50-60Kg/m³.

Back Sheet

The 0.4-0.8mm thickness aluminum or galvanized back sheet adds to the rigidity of the collector.

Riser & Header Pipe

TP2 Cooper laser welding header and riser tubes form a harp shaped heat exchanger together so that the solar heat transfer fluid circulates in heat exchanger.

Aluminum Frame

The 1.5mm thickness 6063-T5 oxidation treatment aluminum frame is widely used for anti-corrosion, anti-rusting, etc.

EPDM Sealing

Special integral EPDM material can avoid leakage perfectly, otherwise, its service life is over 25 years.
