Short answer: for the right roof in the right state, yes — but the right roof in 2026 is more specific than it used to be. The federal residential solar tax credit (§25D) ended December 31, 2025, and that change tightened the math. A larger share of homeowners than before now fall outside the cases where solar pencils. We'll tell you honestly which case you're in. We'd rather you skip than be sold.

Solar still pays back for owner-occupied single-family homes with monthly bills above approximately $250, south- or west-facing unshaded roofs, and addresses in states with strong incentive stacks — particularly New Jersey, Massachusetts, and California (with battery). For mid-bill households ($150–250/mo), a lease or PPA through 2027 may produce better economics than cash purchase, because the §48E commercial credit still flows to the leasing company and the better operators pass some through. For homeowners with bills under ~$150/mo, with cash-only intent at mid bills, with old roofs not due for replacement, with severe shading, or in rental units, the answer in 2026 is honestly: skip, wait, or look at community solar instead.
What changed, in 30 seconds
The Inflation Reduction Act of 2022 set the residential Investment Tax Credit at 30% through 2032. The One Big Beautiful Bill Act, signed July 4, 2025, accelerated that timeline by approximately seven years and terminated §25D entirely for systems placed in service after December 31, 2025 (IRS OBBBA FAQ). There is no transitional rule. Cash and loan buyers in 2026 receive zero federal credit on the system. The §48E commercial credit that lease and PPA providers capture remains available through 2027 (SEIA OBBBA explainer). For a deeper read on what the legislation did and the state-by-state numbers, see our flagship explainer Solar economics in 2026 — what changed and what it means for your roof.
The practical effect is simple: a typical 8 kW system that previously netted approximately $16,800 after the 30% federal credit on a $24,000 list price now costs the homeowner the full $24,000 net. Cash payback periods stretched from approximately 7–11 years pre-§25D to approximately 11–15 years in 2026 — state-dependent. State incentives (SuSI in NJ, SMART in MA, SGIP for batteries in CA, the AZ residential credit, local utility rebates) didn't change. They now do most of the math.
Three buckets — which one are you in?
Solar still works
- Bill $250+/mo ($200+ in NJ/MA)
- South or west exposure, unshaded roof
- Roof in good shape (5+ years of useful life)
- Owner-occupied single-family
- State with strong incentive stack: NJ, MA, CA (battery), AZ
- Open to cash or loan
Look at lease or PPA
- Bill $150–250/mo, any state
- Owner-flexible (don't insist on owning the equipment)
- Want zero upfront cost
- OK with a 20–25 year contract on the home
- In a market with active TPO competition (CA, AZ, NV, FL, parts of TX)
- Comfortable shopping multiple lease quotes
Skip, wait, or community solar
- Renters and condo owners
- Bill under ~$150/mo
- Bill $150–250/mo + cash-only intent
- Roof 20+ yrs old, no replacement plan
- Severe shading or fully north-facing
- Multifamily without HOA buy-in
If you're in the first bucket, the rest of this article walks through what to do next. If you're in the second, the lease pivot is the genuinely useful path through 2027 — and we walk through how to get a meaningful lease quote (not a marketing one) below. If you're in the third, the honest answer in 2026 is one of: wait until you're in the first bucket (renovation, longer ownership horizon, electrification of more loads), look at community solar where available, or invest the cash in weatherization (insulation, air sealing, smart thermostat) instead. Solar is not the right answer for everyone, and 2026 made that more true than 2024 did.
Three modeled scenarios
To make the buckets concrete, here are three modeled scenarios. None of these are real customers — they're representative profiles built from NREL PVWatts production modeling, EIA Electric Power Monthly retail rates, and EnergySage Q1 2026 Marketplace pricing. Real outcomes will differ based on the specific install.
A homeowner in the East Bay with a $340/month average electric bill, 1,900 sq ft single-family home with a south-facing composite-shingle roof in good condition. Owner-minded; planning to stay in the home 15+ years.
System: 8.5 kW panels + 13.5 kWh battery (NEM 3.0 essentially requires battery). List price: ~$36,000. State levers: SGIP rebate on battery (~$2,000–4,000 declining-tier value), no federal credit. Cash net cost: ~$32,000–34,000. Annual production: ~12,500 kWh, displacing ~$4,200/yr at PG&E rates with battery self-consumption. Cash payback: ~13–14 years.
Lease alternative: Per-kWh rate ~$0.20 (vs $0.40 PG&E retail). Annual savings ~$2,500/yr; effective payback via lease ~7–9 years through 2027 §48E passthrough.
Modeled on NREL PVWatts Q4 2025 production figures + PG&E E-ELEC rates as of May 2026. Not a real customer.
A homeowner in suburban Austin with a $190/month average bill (Oncor service area), 2,200 sq ft single-family with a south-southwest roof, 8 years old. Wants the lowest monthly cost; flexible on ownership.
System: 8 kW panels-only. List price: ~$23,000. State levers: Oncor rebate ~$1,500, no state income tax credit, no federal credit. Cash net cost: ~$21,500. Annual savings: ~$1,650/yr at typical Oncor REP buyback rates. Cash payback: ~13–15 years.
Lease alternative: Per-kWh rate ~$0.10 (vs ~$0.13 average TX retail). Annual savings ~$700–900/yr; effective payback via lease ~10–12 years. Lease wins on lifetime cost at this bill level.
Modeled on NREL PVWatts Q4 2025 + Oncor rebate program 2026 data + Austin Energy buyback program rates. Not a real customer.
A homeowner in suburban Worcester with a $130/month average bill (National Grid), 1,400 sq ft single-family, 22-year-old asphalt-shingle roof with no replacement plans, partial afternoon shading from mature oaks.
System would need: 5 kW panels-only (smaller because of bill size and shading). List price: ~$16,000. State levers: SMART per-kWh payments + state income tax credit (up to $1,000), no federal credit. Cash net cost: ~$14,500–15,000. Annual savings: ~$1,200/yr including SMART. Cash payback: ~12–14 years — but the roof has only 5 useful years left, meaning panel removal + reinstall ($5,000–10,000) before payback completes.
Lease alternative: Most TPO providers won't underwrite a 25-year lease on a roof with this remaining life.
Modeled on NREL PVWatts Q4 2025 + MA SMART program 2026 rates + National Grid R-1 residential tariff. Not a real customer.
The 2027 calendar fact
The §48E commercial credit, which makes the lease path work for mid-bill households, also has a sunset. Construction must begin by July 4, 2026 OR the system must be placed in service by December 31, 2027 (26 U.S.C. §48E as amended by OBBBA; Arnold & Porter analysis). After that window closes, even the lease and PPA federal lever disappears unless extended. As of May 2026 there is no active extension effort.
For the second bucket (the lease candidates), this is not abstract. The honest read is: the lease pricing that pencils today has roughly an 18-month window before it disappears. If a lease or PPA is the right move for your household, it's the right move now or in the next 18 months — not in 2028. Expect aggressive marketing from TPO providers in late 2026 and early 2027; some will be honest, some will be pressure-driven, some will be both. Get three lease quotes when you go, ask each one to walk through how much §48E value is being passed through to your per-kWh rate, and decide on the math, not the salesperson.
Why we don't quote lifetime savings
Most installer marketing leads with "lifetime savings" — total dollars saved over 25 years. Those numbers always look big and are almost always overstated. They depend on retail electricity rate inflation (typically assumed at 3–5% annually, often optimistically), system production degradation (about 0.5% per year), what the homeowner actually does with the bill credits, and whether the system reaches its full useful life without major component replacement. Small changes in any of those assumptions move the lifetime number by tens of thousands.
We deliberately don't quote specific lifetime savings figures in our analysis. Too many compounding assumptions stack up over 25 years for the resulting number to be useful in any given homeowner's decision. The number we trust is cash payback period in years — how many years until the system has paid for itself in displaced electricity at today's rates, with no rate-inflation assumption baked in. After that point, all production is upside, but how much upside depends on factors no one can predict 20 years out. If an installer's pitch leads with "$67,000 over 25 years," ask them to walk through the assumptions. They'll usually concede the number assumes rate inflation we can't verify.
The decision in three questions
If you've read this far, the decision usually comes down to three questions:
- What's your average monthly electric bill across the year? Below $150 → skip; $150–250 → look at lease/PPA; $250+ → cash or loan is in play.
- Are you set on owning the system, or open to a lease/PPA arrangement? Owner-only at $250+ in a strong-stack state is a cash candidate; owner-flexible at $150+ is a lease candidate; owner-only at $150–250 is a wait-or-skip case.
- What state are you in, and how old is your roof? NJ/MA/CA-with-battery favor cash; TX/NV/AZ favor lease through 2027. Roof 20+ years old without replacement plans is a defer-everything signal regardless of bill or state.
Marcus walks through these three questions in roughly five minutes and gives you a specific read for your specific roof. The answer is sometimes "yes, here's the configuration that pencils for you" and sometimes "honestly, not in 2026 — here's what to consider instead." Both answers are useful.
Five minutes with Marcus, our AI solar advisor, will tell you which of the three buckets you're in for your specific roof, your specific bill, and your specific state — including whether a lease through 2027 might pencil better than waiting. Free, no follow-up calls you didn't ask for.
