You may have heard, or read, about the solar tax credit (formally called the Federal Investment Tax Credit) in recent months, especially as 2019 wrapped up and we made way for a new decade. In short, this tax credit previously allowed homeowners that installed solar panels on their homes to deduct 30% of their total solar installation costs from their federal tax liability, but after the new year, that deduction amount has been reduced to 26%. 

This is still a substantial incentive for reducing the cost of your solar installation — but many homeowners interested in outfitting their homes with a self-sufficient renewable energy system want to know: Does a solar battery backup system also qualify for the savings of the Federal Investment Tax Credit?

Combining Solar and Battery Storage

Solar battery storage systems, like the Tesla home battery product called Tesla Powerwall, are connected to the inverters and solar panels of a residential solar PV (photovoltaic) system. This allows the system to bypass the safety mechanisms that require standard solar PV systems to connect the greater electric grid.

Solar battery storage systems save all of the excess electricity that solar panels can generate during the day, and use that electricity to power a home or business after the sun has gone down, during peak charging or even during a power outage. 

A solar-plus-storage system can help you maximize the renewable energy potential of your Denver, Colorado Springs, Pueblo, Aurora, Colorado or San Antonio, Austin, and Rio Grande Valley, Texas home. So how does this fit into the 2020 federal tax breaks for installing solar panels?

Reducing the Cost of Solar Plus Storage

The short answer to using the 2020 solar tax credit for battery storage? YES. 

But there is a caveat!

In order to qualify, the batteries you choose (including a Tesla solar battery) must “derive 100% of (its) power from an onsite solar array”.  This means you cannot be charging your batteries with grid-supplied power — which is not too hard if you are planning to use your battery storage solely with solar or to take your home completely off the grid!

However, the rules are a little different for commercial systems. Commercial solar PV systems are required to derive a minimum of 75% of their power from solar, on a sliding scale to be eligible. For example, a commercial solar PV system charged 100% by solar would be eligible for the full tax credit of 26%. However, if it is only charged 75% of the time by solar, it would be eligible for 75% of the tax credit, which pencils out to 19.5%.
