SUNEARTH Inc-SunEarth Empire EP-32 Collector

SunEarth Empire Flat Plate 4 x 8 Collector

Solar Collectors—or panels—gather energy radiated by the sun and convert it into useful heat in the form of hot water. Collectors work alongside your conventional water heater to ensure year round hot water. The Empire Collectors, manufactured by SunEarth, are flat plate type. SunEarth designs and builds solar components that survive the world's most challenging climates and environmental conditions. Empire collectors are manufactured for a thirty-year design life, they require little or no maintenance and are backed by a solid ten year warranty.

How It Works:
Flat plate collectors capture solar energy by employing the green house effect. The glass covering permits up to 90% of the visible sunlight to enter the collector. When the light passes through the glass its frequency is changed slightly to a lower energy level. When the light strikes the absorbing surface of the flat plate inside, the light is absorbed as heat. The combination of the glass frequency change and the solar absorbing surface of the plate capture the maximum amount of energy. As the absorber plate heats up it begins to radiate energy as infrared (IR) or heat radiation. Glass is essentially opaque to IR wavelengths so the heat is trapped increasing the temperature.
