Solar power set ups usually come at a high cost. They can range from a thousand dollars to thousands more depending on where you live. There are two different types of tax incentives, one is a tax credit and the other is a tax deduction. Tax credits make a bigger difference than a tax deduction, and the government currently offers them for installing a solar heating system!
Solar heating is efficient, and the government is taking notice. Because of this, if you purchase a solar lighting or heating set up you can become eligible for a tax credit. The credit available for you varies, but they are usually at least $500. This means that instead of owing say, $8000 you can owe only $7500. These credits make a huge difference when it comes to paying your taxes!
