Make sure that any solar panels you put up are actually cost effective. While the installation cost can be dented with government assistance, you need to know how long it will take for energy savings to return your investment. Also factor in that you are not likely to get the same amount of power every single month.
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.
