This type of solar collector uses a series of evacuated tubes to heat water for use. These tubes utilize a vacuum, or evacuated space, to capture the suns energy while minimizing the loss of heat to the surroundings. They have an inner metal tube which acts as the absorber plate, which is connected to a heat pipe to carry the heat collected from the Sun to the …

Get PriceSunplate® Solar Collectors | Opaque Cover Technology
But unlike current medium temperature solar collectors, the interior surface of the cover plate is designed to be hotter than the absorber during normal operation. This increases energy transfer from the opaque cover to the absorber because infrared energy emittance increases to the fourth power of the temperature of the emitting surface.
