The catch on most of these credits is they need to be on existing principal residence property instead of a new home or rental units. The exception comes for large scale projects of small wind turbines, solar, and geothermal energy systems. These incentives can be used on new homes.  

If you're thinking solar and live in California, Colorado, Connecticut, New Jersey, or Vermont, then be sure to check out Real Good Solar content where one lucky homeowner will win a free solar electric system for their home (up to 4 kilowatts DC) valued at up to $25,000.  

You can enter this sweepstakes by visiting the following this link or by calling 888.56.SOLAR.  

John Schaeffer, Residential President of Real Goods, commented, "What better way to lower utility bills than with solar? Our customers frequently see a return on investment of over 20% for a purchased solar system, or a low money down and lower monthly bills on a power plan purchase. We're happy to offer this sweepstakes to highlight the importance of converting to a solar economy!"  

If you're like a large number of your neighbors who have chosen to stay put and remodel their homes during this down housing market then chances are you've put a substantial amount of money into your home. These tax credits add up quick so be sure to take all for which you qualify!
