SolarRating OnLine gives you the information needed to confirm solar technology at your home is a smart investment - one that protects the environment but also reduces YOUR long term energy costs. Green Power Labs' innovative site assessment tool, SolarRating OnLine determines a homes' suitability to solar technology used either to heat water or to generate electricity. Suitability refers to the amount of energy it is possible to produce at a home using solar technology to reduce a family's long term energy costs by replacing a part of the current energy source - oil, gas, propane or grid electricity - with energy taken from the sun. SolarRating OnLine gives each home a color-coded rating and is the first step in understanding how solar technology might be used to reduce your family's energy costs.
