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.

Glazed Flat Plate Solar Collector
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.

Empire & ThermoRay Solar Collectors

We at Sun Source are proud to carry the SunEarth Empire & ThermoRay series of flat plate collectors. These products provide 3 different levels of efficiency in a sleek, low profile black anodized aluminum frame. All collectors are glazed with low-e tempered glass, and insulated with both insulation board and fiberglass to provide the highest performance levels in the industry.

  • EP Series (Selective Paint) - The most cost effective collector. All copper absorber and copper riser tubes, coated with a low-e black paint. This collector is very popular in the south and mid-Atlantic, and it's low price point provides a great ROI to the customer.
  • EC Series (Black Chrome) - The most popular choice, and long time highest efficiency. All copper absorber and copper risers, coated with black chrome. This collector is very effective in Northern climates to provide winter performance, and is priced very aggressively.
  • TRB Series (Blue Sputter) - The "ThermoRay" is the highest efficiency collector on the market. Aluminum absorber plate and copper risers. This collector provides extremely high performance and is the goto choice for high demand systems in Northern climates.
