I’m thinking of adding solar panels to my home. Can I still get a tax break?

Yes, you can claim a credit for 30% of the total cost. For solar energy systems installed in a residence, the full credit applies through 2019 and then phases out… 26% for 2020 and 22% for 2021…until it ends after 2021. Ditto for the breaks for geothermal heat pumps, residential wind turbines and fuel cell property. What if I put in energy-efficient windows or doors? You’re out of luck, for now. The limited tax credit for these residential energy-saving items lapsed after 2017.
