 Flat Plate Solar Thermal Collectors

Technical data:

Working Principle:

Flat panel collectors working principle is different from evacuated tubes collector. A glazed flat-plate solar collector consists of a shallow rectangular box with a flat black plate behind a tempered glass cover. The plate is attached to a series of parallel tubes or one serpentine tube through which water or another liquid (such as an antifreeze solution) passes. Sunlight passes through the glazing and strikes the absorber plate, which heats up, changing sunshine into heat energy. The heat is transferred to liquid passing through pipes attached to the absorber plate. Bontel can supply you different kinds of high quality absorber plate with selective film.

BTE Advantages:

1.The high weather-proof selective absorbing film from full-automatic magnetron sputtering production line developed by Bontel;

2.With Bonding heat transferring technology and laser welding technology;

3.High quality low-iron tempered glass with surface treatment to get high transmittance and low emittance;

4.Circulation fluid in closed copper pipes, no glass tubes. So collectors without corrosion and circulation fluid leaking;

5.The solid built-in absorber plate can absorb all solar radiation improve working efficiency and integrated well with buildings.

Product Pictures

The whole plate has  less heat loss with laser welding, better heat collection efficiency and beautiful appearance.

The plate solar collector is composed of heat absorbing board core, shell, transparent cover plate, insulation material and related parts. After adding the circulating pipe, the heat preservation tank can absorb the radiant heat of the sun and raise the water temperature.
