PG series flat plate Solar Collector
PG-F/G
PG-F/L
Features

Sunda flat plate collectors are manufactured with reference to international standards. The heart of the solar collector is the Sunstrip aluminium fin absorber. The absorber is integrated with a copper tube water offering excellent pressure endurance and high efficiency. The anodized surface with its selective effects is providing for even greater perfection. The framework of the collector is made of thick aluminium profile in an elegant and practical shape. The back cover is made of a galvanized steel plate with 0.5 mm thickness. The absorber is made of Sun strip and coated with selective coating to maximize the absorption of solar irradiation and to minimize heat losses. The collector also features thermal insulation made of glass wool (32kg/m3 and 30 mm thick), tempered glass gaskets for high endurance to the sun and offers highest cost-effectiveness.

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.
