Product Detailed
Different latest types of solar water heater (solar energy water heater) are available with high quality and competitive price


1- Aluminum profile securing the cover 2 Absorbent surface made of selective coated copper fins for maximum performance: 3- Absorber risers made of 10 mm diameter Copper tubes: 4- Special 4 mm thick glass, tempered highly permeable: 5- Back plane insulated by 40 mm rock wool:


 There are two main forms of solar panels on the market:  


Flat Plate collectors and Evacuated Tube collectors

The main component of each is the absorber, which absorbs solar radiation and converts it into heat: In a plate collector, the absorber is in the form of a flat, black plate in a shallow metal container covered with one or more layers of transparent glass or plastic; either air or a liquid is circulated through the cavity of the container: Heat is directly transferred from the absorber to the circulating liquid (air, water)

The absorber in an Evacuated tube collector consists  of a relatively narrow strip of copper with a selective black coating bonded to a single copper tube:

The tube contains a special fluid which evaporates when heated: This vapour rises and transfers heat to the water circulating in the systems primary circuit:

Evacuated tubes are the most efficient solar collector used for solar water heating systems: These units perform excellent in any location and the improvement is particularly noticeable in colder climates and on darker days:

Evacuated tubes are also more efficient than flat plate collectors; consequently they take up less space: They are, however, more expensive that flat plate: Generally speaking, to produce a given amount of hot water, whether using flat plate or evaporated tubes, the installation costs will be roughly the same.
