Available solar energy at your home is based on these primary factors:

• Location
  Solar energy is not evenly distributed over the surface of the earth, and your geographical location – specifically latitude - is an important factor.
• Orientation to South
  When roof or wall segments of your home face south, south-east or south-west, it is more likely your home is solar "friendly".
• Slope
  Ideal slope or angle for the area where the solar panels will be placed depends on location and local climate. Together these factors determine whether a steeper or gentler slope increases the potential for solar energy. In our SolarRating Online analysis we are only concerned about that portion of the roof or wall where solar panels will be placed. In a later step in SolarRating Online this information will be used to help determine your home's suitability for solar technology.
• Shading
  Shadows created on solar panels by surrounding buildings, trees, and hills reduce the amount of solar energy available.

Now, let's calculate how location, orientation, roof slope and shading impact your share of the sun. We will walk you through several simple steps to determine the impact of each of these factors at your home. And then SolarRating Online service will rate your home's suitability for solar energy technology.
