Features

Flat plate collector is the most popular in Europe and America for its excellent cost performance and long life cycle over 25 years. Because of its brilliant high efficiency in the low operating temperature range, they are widely used in the world. Sunda flat plate collector is a famous collector brand in China and from the raw material selection to the production processing its quality has been very strictly controlled. Comparing with other type of solar collectors, the flat plate collector has the best cost-effectiveness. It is suitable for the region, where solar resource is good and the freezing period is very short.

The core component of the solar collector is the absorber. Our absorber - “Sunstrip” is very famous type for decades of years throughout the world, which fin's metallurgically-bonded aluminum completely surrounds a copper tube waterway. The corrosion resistance of copper combined with the light weight and high thermal conductivity of aluminum produces the optimal finned tube. The metalurgical bond provides superior thermal contact resulting in superior heat absorption and conductivity, and long-term durability. Sunstrip fins and absorbers are high in efficiency, light in weight, technologically advanced, and offer attractive economics.
Selective coating on absorber will be the anodized Al or sputtering Al-N-O for your choice. Anodizing coating owns strongest weather resistance, which can work very well in any place. Sputtering coating is popular advanced selective coating technology, which has very high absorptance and lower emittance to improve overall performance of collector effectively.

Our another kind of full plate absorber adopts full plate laser welding technology, which ensures high efficiency and much better appearance.
Selective coating adopts international superior efficient absorber layer inside. Solar absorptance can reach 0.95 ± 0.02 and thermal emittance can fall to 0.04± 0.02.

Application


This flat plate collector has already a history of over 60 years. Its high efficiency in the low operating temperature range has advanced its worldwide dissemination. The strict quality control from the raw material selection to the production processing has established the Sunda flat plate collector as a famous collector brand in China. The collector has the highest cost-effectiveness compared with other types of solar collectors and is suitable for regions with high annual solar irradiation and short winter.


An important asset of flat plate solar collectors is their versatility. One of the application areas for flat plate solar collectors is domestic water heating. Therefore installation requires remarkably little space making it practically applicable at any domestic place. Despite their little size, the collectors still cover over 70% of the hot water needs of an average household. Their excellent efficiency makes them also suitable for the operation of larger systems for commercial or public use.
