Solar electric systems qualify for a 26% federal tax credit in 2020. This applies to both residential and commercial solar PV systems. This credit is a dollar-for-dollar tax credit and will reduce the amount of tax owed by the system owner before any deductions are applied.

EV CHARGING: In 2019, the US Congress extended a residential tax credit for up to 30% rebate ($1,000) on the installation of EV charging stations, applied retroactively, as well as through the end of 2020.


Owners of new residential and commercial solar can deduct 22 percent of the cost of the system from their taxes.
