Product Description

2m2 and 3m2 flat plate solar 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 Frame

high tensile 6063 aluminium alloy


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

Back Sheet

A galvanized sheet seals the back of the panel and adds to the rigidity of the collector.  


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


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.

1. Certified with European Solar Keymark

2. high annual energy yield up to 1002kwh for 2m2 flat plate solar collector, guarantee for high government subdidy. 

3. 95mm thickness for less heat loss. 

4. blue-titanium selective-coating absorber, ensuring the high sunshine absorption rate. 

5. annual production capacity of 300,000 sets. 

6. high efficiency of 80.5% for 2 sqm flat plate collector.
