Do your own research and find out if there are any rebates available for adding a solar system to your home. There are many local, state and federal programs that offer rebates for installing solar power in your home. Also check to see if you are eligible for tax incentives as well.
You might be able to get your solar energy equipment installed for a huge discount or perhaps even free. The government is trying to promote solar energy benefits and many wish to cover apart or all of the costs in return for its installation.
