Keep your solar panels out of the shade. It might seem obvious, but your solar panels do need sun. Make sure that you are not installing them in the shade. Trim back the branches on surrounding trees if you need to. Failing to do so could cost you more than half your energy output.
Track numbers when getting solar panels for the home. Solar panels might not be a good option if you cannot count on optimal exposure to sun rays in your area or if you use more power than a regular solar energy system can generate. You need to do all your homework, so you know if this type of energy is really going to save you money.
