Flat Plate Collectors has been around for long time and it is most widely used type of solar thermal panel for domestic hot water supply.
Choice of material and design aspect can greatly affect not only solar thermal performance but also the reliability when operating in many varied environmental conditions. Our Flat Plate Collectors are made from only highest quality materials to ensure reliable, efficient operation and collector longevity
Toughened glass (glazing) protects the absorber from the outside environment while allowing through >90% of sunlight.
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.
A thin sheet of Aluminum/Copper is coated with a highly selective material (Blue Tech ETA Plus) that is extremely efficient at absorbing sunlight and converting it into usable heat. The aluminum sheet is ultrasonically welded to the copper riser pipes.
An aluminum alloy sheet seals the back of the panel and adds to the rigidity of the collector
Header & Riser Pipes
The copper 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
Extruded from high tensile 6063 aluminum alloy, the rails form the outer framework of the collector and are designed with wings for easy mounting frame attachment
Solar Key mark, SRCC, SABS certified EN 12975-1, 2 ISO9806-1 .
Domestic Model FPCC water heaters come in different sizes. Generally, for a Nepali family it starts with 250 liters to 500 liters system. These systems are integrated systems of collectors and storage tanks.
