Yes. The federal government has offered a long-standing Income Tax Credit (ITC) that returns 26% of your total investment in solar. State rebates/credits have largely been exhausted years ago, but there are some credits offered by specific utility companies for adding battery back-up to your solar system. They know this will further lighten your dependence on the grid, so they periodically offer rebates toward battery purchases. Speak to your local Solar Professional for more information.
