The efficiency of a solar energy system varies a lot depending on its exposure to the sun. If you live in a sunny area, your system should produce enough energy to cover all your needs but solar energy might not be such a good investment if you live in an area where the sky is usually filled with clouds.
Think about the money that you send to your power companies each month. How would you like to keep that money in your pocket? Changing to solar power will do that for you. After you pay off the initial investment, the money you used to pay to the power company will stay in your wallet.
