Cooler Planet, 21 September 2011, There is a lot of information circulating about the best location, climate and structure conditions for a solar panel system. Many people assume that a sunny location is all you need. If that’s true, why is Germany (with 9,785 MW of solar energy in 2010) the country with the most solar installations? And how come New Jersey (with 293 MW of solar energy in 2010) is one of the U.S. states with the highest number of solar arrays? Germany and New Jersey aren’t known for their sunny weather, showing that geographic location isn’t the most important factor when considering a solar system. What is important in determining the feasibility and efficiency of a system is the orientation of the roof, amount of sun exposure on the home, and amount of space available for the installation.
Even if you don’t live in sunny California, your home may be in a position that is perfect for PV panels. Listed below are the things you should consider when evaluating whether or not your home is a good candidate for a solar PV system.
Southern Facing Roof
The orientation of your roof is very important when considering the possibility of installing a solar PV system. A southern facing roof is ideal for a solar panel installation, however east and west facing roofs will also work. The southern facing portion will receive the most hours of direct sunlight throughout the day, making the system as efficient as possible. A pitched roof is optimal in order to receive southern facing exposure but a flat roof will also work. If the roof is flat, the installer will attach the panels to a frame that is tilted at the optimal angle. Read More
