IRS Issues Ruling on the ITC Eligibility of Residential Energy Storage Retrofits
The Internal Revenue Service (IRS) has released a private letter ruling (PLR) related to tax credit eligibility when retrofitting an energy storage system onto a home with an existing solar PV system. The PLR determined that a retrofitted storage system would in fact qualify for a 30% federal investment tax credit (ITC), “under code 25D(d)(2) as a qualified solar electric property expenditure”, assuming that the battery charges entirely from the solar system.
