Our estimates are based on national average costs per watt ($2.50-$3.80) adjusted for your location, roof direction, and shading. Actual costs depend on your specific installer, equipment brand, and state/utility incentives. The federal residential solar tax credit expired 12/31/2025, so the calculator shows installed cost without any federal credit deduction.
Permit requirements in Stamford follow Connecticut state building code plus local amendments. No — not for owner-financed residential solar. The Section 25D Residential Clean Energy Credit expired December 31, 2025 under the One Big Beautiful Bill Act (P.L. 119-21). Systems placed in service on or after January 1, 2026 receive no federal credit. One exception: third-party-owned (TPO) or leased systems qualify for the commercial Section 48E ITC at 30% through 2027, because the tax credit flows to the system owner (the leasing company), not the homeowner. See our Connecticut permit guide for specifics.
Without the federal credit, payback periods in 2026 typically run 10-14 years for owner-financed residential solar, depending on your state. High-electricity-rate states with strong net metering (CA, HI, MA, NY) still pay back in under 10 years thanks to utility-bill savings. Cloudy, low-rate states (KY, WV, LA) can stretch past 15 years. Check DSIRE (dsireusa.org) for state incentives that shorten payback.
Yes, batteries can be retrofitted to an existing solar array. A typical residential battery system costs $10,000-$15,000 installed. Federal tax treatment of standalone battery storage changed under OBBB — verify the current year's eligibility with your installer and a tax professional before relying on any credit.
Yes. Zillow research shows solar panels increase home value by approximately 4.1%. On a $400,000 home, that is about $16,400 in added value.
