Keep in mind that purchasing a solar power system often enables you to receive tax credits from the government. You may find that you get back as much as 30 percent of the total cost of your system. So, if you look into a system and think that it costs too much, investigate whether or not you will get credit back to determine how affordable it actually is.
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.
