When you have clear and unobstructed access to sunlight, a roof or area large enough to accommodate it, if its worth the investments and you have local permitts and covenants than our home solar electric system will work for you. Before selcting system components and size a PV system for an existing home, you should evaluate your energy consumption patterns and try to reduce your home's electricity use. If you'll understand the "energy habits" and become more energy efficient, you can reduce the size of the PV system. You should lower your both capital and operating costs. If you decide to put our solar PV panels on your roof you will save thousands of dollars. Solar power's main benefit is energy independence. We cann't buy "fuel" for solar panel as its free for all of us to use. When you have your own solar panels on your roof, you have an essentially independent source of electricity that is all yours.
