One of the nice features of using solar energy is that it not only saves you money, but it is also totally renewable, soundless and produces no pollution. This is why it is such a great option for both private residences, and large businesses to be more environmentally friendly.
Check with your local power company as to whether they have a program to buy excess electricity collected by your solar panels. Some utility companies will give homeowners credits to apply to any energy provided to them. These programs are becoming more available as more and more people install solar panels on their home.
