by the incentive. Hence, people will opt for the safe and solid SRCC-rated heater, which qualifies for the tax credit. Since a 30 percent tax credit is quite substantial, the wider spread use of the solar heating technology will undoubtedly grow once the law has been amended to be more specific.

Considering solar heating systems from an efficiency viewpoint, it would fall between solar water heating and solar electricity - the former offers 60 percent efficiency while the latter offers 15 percent efficiency. While solar water heating is similar to solar heating, the latter which uses thermal technology, solar water heating is used only half as much as solar heating, hence, its energy payback is about 30 percent

Federal legislatures on the tax incentives are not the same as those made by state legislatures; even so, legislatures can differ markedly from state to state. A surer bet for making sure you will qualify for the tax credit on your solar system installation is to use radiant heating in your solar water heater. Do your diligent research, since even this is still subject to the tax attorney’s interpretation of the tax law.
