There is a 30% federal tax credit for solar systems. Many states have incentives for
buying solar technologies. Check with your state or local energy office. Some electric utilities offer rebates to customers who install solar energy equipment because these installations help utilities reduce energy use during times of high demand.

You can also check the National Database of State Incentives for Renewable Energy (DSIRE). DSIRE s prepared by the North Carolina Solar Center. It provides information on financial and regulatory incentives to promote renewable energy technologies.
