The federal solar incentive for residential building-integrated photovoltaic (PV) systems is known as the Residential Renewable Energy Tax Credit, also referred to as the federal Investment Tax Credit (ITC). This incentive allows homeowners to deduct a portion of the cost of their building-integrated PV system from their federal taxes.

Under the current guidelines, the ITC provides a 26% tax credit for residential solar installations, including building-integrated PV systems. This means that homeowners can deduct 26% of the total system costs (including installation) from their federal tax liability. For example, if a building-integrated PV system costs $20,000, the homeowner could receive a tax credit of $5,200 (26% of $20,000).

It’s important to note that the ITC is subject to change and may be phased out or reduced in the future. Therefore, homeowners considering a building-integrated PV system should consult with a tax professional or the Internal Revenue Service (IRS) for the most up-to-date information on incentives and eligibility requirements.
