High Heat Efficient Flat Plate Solar Panel Collector With Black Chrome Coating Absorber

High Heat Efficient Flat Plate Solar Panel Collector With Black Chrome Coating Absorber

Description:

Flat plate solar collector is a device that absorbs solar energy from the sun and converts it into usable heat energy, the heat is normally absorbed by water in the loop, or a freeze-resistant water mixture, a kind of medium used to supplement hot water heating or house air heating.

Glass

Toughened glass (glazing) protects the absorber from the outside environment while allowing through >90% of sunlight.

Absorber

A thin sheet of Aluminium is coated with a highly selective material that is extremely efficient at absorbing sunlight and converting it into usable heat. The aluminium sheet is ultrasonically welded to the copper riser pipes.

Insulation

The insulation helps reduce heat loss from the sides and back of the collector. Made from ultra-light weight melamine foam this material is chosen to greatly reduce the weight of the collector.

Back Sheet

An aluminium alloy sheet seals the back of the panel and adds to the rigidity of the collector.

Riser & Header Pipe

The header and riser pipes are brazed together to form a harp shaped heat exchanger that the solar system heat transfer fluid circulates through. The absorber sheet is ultrasonically welded to the riser pipes, thus transfers heat to the heat transfer fluid.

Aluminium Rails

Extruded from high tensile 6063 aluminium alloy, the rails form the outer framework of the collector and are designed with wings for easy mounting frame attachment.

Working Principle

The selective coating on the inner cover of the evacuated tubes converts solar energy into heat energy and water in evacuated tubes the heat. When temperature rises along with density drops, and weight goes down, hot water will go up to exchange with cold water in tank. In this way, the temperature of the water in tank goes up.

Applications:

Domestic hot water for shower, washing. Solar Thermal, Project: such as School, Hospital, Hotel.

Competitive Advantage:

1. Suitable for domestic, dormitories, parks, hotels, schools, public showers, swimming pools, restaurants and other sites requiring for large hot water use

2. Flat plate solar collector presents a tube plate structure with a high efficiency, pressurized, insolation resistant, reliable quality with 15 years lifespan.

3. Suitable for open or closed Loop (glycol-water) active solar water heating system.

4. Flat plate is suggested to be used in non-frozen area, in frozen area, it is suggested to be used in active closed loop system with anti-freezing liquid for heat exchange.

5. Easy installation on slope or flat roof with little maintenance needed.

6. The high absorption: αs ≥ 92%, low emissivity: εh ≤ 10%, daily thermal efficiency ηd ≥ 55%
