Solar Savings Calculator: How Much Can Solar Save You in 2026?
Our Solar Savings Calculator uses your ZIP code and monthly electricity bill to estimate solar panel installations in your area. It analyzes local sun exposure, electricity rates, and current state incentives to give personalized results in seconds — no email required.
The 30% federal residential solar tax credit (Section 25D) expired December 31, 2025 under the One Big Beautiful Bill Act. New 2026 installations no longer qualify for the federal credit, but many states still offer property-tax exemptions, sales-tax exemptions, state income-tax credits, and net metering. This Solar Savings Calculator automatically loads 2026 state incentive data for your location.
What to Enter & Why It Matters
ZIP Code: Your ZIP sets your local peak sun hours and electricity rate — the two biggest drivers of solar savings. Sunnier regions and higher electricity rates both shorten payback.
Monthly Electricity Bill: The calculator converts your bill into annual kWh at your local rate, then sizes a system to offset roughly 85% of your usage.
Roof Orientation: South-facing roofs are optimal; east-west roofs produce about 90% as much, and north-facing about 75%. The calculator adjusts system size accordingly.
Solar Installation Costs in 2026
The US average installed cost is about $3.75 per watt in 2026. Because the federal credit expired, your net cost now equals the gross system cost minus any state-level credits. A typical home solar system adds roughly $15,000–$25,000 in home value, according to Zillow/NREL research.
Over a 25-year horizon, electricity rates are projected to rise about 4% per year — which is why locking in solar today compounds your savings. See our solar incentives guide for what your state offers.
Financing changes the math too. A cash purchase has the shortest payback since there's no interest to offset, while solar loans spread the cost over 10–25 years — often keeping your total monthly payment (loan plus reduced utility bill) below what you paid before going solar. Leases and power purchase agreements require $0 down but forfeit the home-value increase and any state incentives, since the leasing company keeps them. Run the numbers for your specific bill and location with the Solar Savings Calculator before comparing financing offers, so you already know what a fair cash-purchase price looks like.
Frequently Asked Questions
Savings depend on your electricity bill, local sun hours, and state net-metering policy. Most homes offset 85% of their electricity use — enter your ZIP and bill above for a personalized first-year and 25-year savings estimate.
No. The 30% federal residential solar tax credit (Section 25D) expired December 31, 2025 under the OBBBA. Many states still offer meaningful incentives, which this calculator shows for your state.
About $3.75 per watt installed on average in 2026. The calculator estimates your exact system size and cost from your bill and location.
Payback depends on your rates and sun hours. The calculator computes your break-even year using a compounded 4%/year rate-escalation projection over 25 years.
It combines your ZIP code's average sun hours and electricity rate with current state incentive data to model system size, cost, and savings. It's a solid planning estimate — for an exact number, compare 3+ installer quotes using your actual roof and utility rate.
Property-tax exemptions, sales-tax exemptions, state income-tax credits, and net-metering policy for all 50 states plus D.C., updated for 2026. The federal 30% credit is not included since it expired December 31, 2025.
Yes, as a starting point. The Solar Savings Calculator combines your ZIP code's sun hours, your local electricity rate, and current state incentive rules to model system size and 25-year savings without needing an inspection. What it can't see is roof condition, shading from trees, unusual roof pitch, or your specific electrical panel — factors an installer checks on-site. Think of the Solar Savings Calculator as the number to walk into quote conversations with, not the final contract price. Most homeowners find installer quotes land within 10–15% of the calculator's estimate once shading and roof specifics are confirmed.
