Solar Panel System Installation - FAQs

You must have your solar (and/or battery) system installed and generating electricity by December 31, 2025 to claim the 30% federal tax credit. Skipping this deadline means losing one of the largest solar incentives in U.S. history.

With average system costs at about $28,000 (≈ $2.50 per watt), the 30% tax credit reduces the net cost to around $19,400—saving you roughly $9,000

It typically takes 60 to 90 days from contract signing through design, permitting, installation, and interconnection. Starting early—even allowing 4–5 months—is strongly advised to avoid missing the deadline.

The current law requires “expenditures made” by the deadline, which is less clear than the old “placed in service” language. The safest route? Ensure your system is installed and operating by December 31, 2025, even if interconnection is delayed.

Covered: Solar panels, equipment, installation labor, permitting, and necessary electrical work. Not covered: Roof repairs/replacement, financing fees, ongoing maintenance plans, or cosmetic upgrades.

Yes. The credit applies whether you pay in cash, loan, or HELOC—even if the loan isn’t paid off by year-end. However, if you lease or enter a PPA, the credit goes to the owner (not you), although those contracts remain eligible through later deadlines.

Yes—batteries installed with your solar system by December 31, 2025, are also eligible for the 30% credit. If you lease, the owner can claim a reduced battery credit through 2035 under a phased schedule.

The solar tax credit is non-refundable—it reduces your tax liability, not your tax refund. But any unused portion can likely be rolled over to future years, though IRS Form 5695 may be altered post-2025.

Protect yourself by choosing established installers, considering third-party protection plans (e.g., Solar Insure), and knowing that manufacturer equipment warranties typically remain valid regardless of installer status.

Yes—solar systems now cost less than ever (≈ $2.50/W), and electricity prices are expected to rise. Even without the credit, going solar can be a wise, long-term investment—especially when backed by personal values and energy independence goals.
