Yes. If you purchase a solar system, the federal government will give you a 30% tax credit on the total you paid which may be used in a single year or spread out over five years. The current federal solar tax (ITC) credit is set to decrease to 26% in 2033, so the time to go solar and save the most is now! Also, the state of California offers a $1,000 tax credit for a new solar system. Leased solar systems are not eligible for tax credits.
