As we mentioned in a previous announcement
, adding battery backup to an existing residential PV system of a battery, inverter, wiring and software is now subject to the 30% Investment Tax Credit (ITC) as long as it is only charged by the sun.
That makes this next year and a half an important time period for people interested in adding battery back up to their rooftop PV system! The ITC is scheduled to be reduced to 26% in 2020, 22% in 2021. After December 31st, 2021, the residential tax credit will officially end and the commercial and utility credit will drop to a permanent 10%.
