What home solar costs in Portsmouth - and the 2026 rules that changed the math
Every solar decision in Portsmouth now comes down to three things: the real installed price (about $2.58 a watt at the U.S. marketplace average), what your utility pays for exported power under Virginia rules, and whatever state-level incentives survive in 2026.
Installed home solar for Portsmouth homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Portsmouth systems completed in 2026 get $0 from it.
Under Virginia's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Portsmouth plus 9 surrounding towns within 40 km form one installer market of about 1,485,955 people - quotes should not vary much by town.
A fair 2026 solar decision in Portsmouth needs three numbers side by side: the installed price (compare against $2.58 a watt), your utility's export rate under Virginia rules, and your actual daytime usage. Miss any one and the payback estimate on a sales slide is fiction.
Portsmouth has about 96,482 residents, and every solar quote here is built from the same inputs: system size, roof complexity, and what your utility pays for exported power under Virginia rules. The marketplace average runs about $2.58 a watt installed - quotes far above that deserve an explanation, not a signature.

The 30% federal tax credit is gone for 2026 installations
The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, the credit is not available for any property placed in service after December 31, 2025 - and the IRS counts the installation completion date, not the contract date.
Virginia rules that decide your payback
| Rule | Virginia status |
|---|---|
| Export compensation (net metering) | Net energy metering with kilowatt-hour credits: "Any billing period credits shall be accumulated, carried forward, and applied at the first opportunity to any billing periods having positive net consumptions," with residential systems capped at 25 kW for investor-owned utilities and 20 kW for electric cooperatives, and the program remaining open until net-metered capacity reaches six percent of each utility's adjusted Virginia peak-load forecast (five percent general, one percent reserved for low-income customers). |
| State incentive | Virginia's SREC market, created by the Virginia Clean Economy Act RPS — Va. Code § 56-585.5 requires a Phase II Utility (Dominion) to meet "4.5 percent for the 2026 through 2030 compliance years" of its RPS obligation with solar, wind or anaerobic digestion resources of one megawatt or less located in the Commonwealth, and "65 percent of such generation capacity procured shall be from the purchase of energy, capacity, and environmental attributes from solar facilities owned by persons other than a utility" — which is what creates demand for rooftop SRECs. There is no statewide rebate; the other state-level benefit is the local-option property tax exemption under Va. Code § 58.1-3661. |
| Sales tax on the system | Not exempt - taxed like any purchase |
| Property tax on added home value | Excluded |
Virginia has a real solar-rights law: under Va. Code § 55.1-1820.1, "No association shall prohibit an owner from installing a solar energy collection device on that owner's property unless the recorded declaration for the association establishes such a prohibition," and an HOA restriction is deemed unreasonable if it "increases the cost of installation ... by five percent" or "reduces the energy production ... by 10 percent." Offsetting that, Dominion residential customers whose systems exceed 20 kW AC pay a monthly standby charge, and unused kWh credits left at the end of the 12-month net metering period are forfeited unless the customer has a power purchase agreement to sell the excess.

Why only these platforms
In solar, the expensive mistake is rarely the price per watt - it is the wrong contract: a 20-25 year lease with an escalator clause, financing with a buried dealer fee, or an oversized system in a state that pays pennies for exports. A slightly higher bid from an installer with a decade of local history is usually the cheap option.
Solar lead generation is where most industry abuse lives, so this guide only links platforms that show you multiple named installers and let you walk away - never single-installer funnels or phone-blast forms. If a platform falls below that bar it gets removed from every page on this site.
| Platform | What you get | Background |
|---|---|---|
| EnergySage | Side-by-side bids from multiple installers | The largest U.S. solar marketplace; publishes its pricing data publicly |
| Modernize | Matched with vetted local installers | Established home-services network (QuinStreet); installers are screened |
Getting quotes in Portsmouth
Before requesting quotes, have your last 12 months of electricity bills handy - system sizing should follow your real usage, not a salesperson's template. A bid sized far above your usage is a margin play, especially now that surplus export pays less in most states.
- Your last 12 months of electricity bills - sizing should follow real usage
- Roof age and type - reroofing after panels go up is expensive
- Your utility's export rate under Virginia rules - it decides the payback
- Whether you want backup power - that is a battery decision, priced separately
- Written itemization: hardware, labor, permits, and any financing dealer fee
Reading a Portsmouth roof honestly
Same-day contracts are a red flag in this industry. Legitimate VA installers expect you to compare bids, check licenses, and read the interconnection terms. Anyone pressuring you to sign at the kitchen table is pricing in your haste.

Common questions
Does solar raise my property taxes?
It depends on the state - many exempt solar's added home value from property tax, others do not, and some exemptions have expiration dates. This guide's state page lists the verified rule and source for your state.
Is solar still worth it without the federal credit?
It depends mostly on your state's export rules and your daytime usage. Paybacks lengthened by roughly a third when the credit ended, but rising electricity rates and record-cheap hardware keep the math workable in states with decent export compensation - and marginal where exports pay avoided cost only.
Is my roof even suitable for solar?
Three things decide it: orientation (south-facing is best in the U.S., east-west workable), shade (trees or taller buildings across midday hours can sink the math), and roof age (if the shingles have under 10 years left, reroof first - removing and reinstalling panels later costs thousands). Any honest installer assesses all three before quoting a number.
How do I check if a solar quote is fair?
Divide the total price by the system's wattage. The U.S. marketplace average is about $2.58 per watt installed; $2.30-3.00 covers most fair quotes depending on roof complexity. Above that, ask exactly what you are paying extra for - in writing.
What happens if my installer goes out of business?
Panel and inverter warranties come from the manufacturers and survive, but the workmanship warranty usually dies with the company. That is a real risk in the post-credit shakeout - prefer installers with years of local history, and get manufacturer-backed workmanship coverage where offered.
Should I lease, get a PPA, or buy?
Buying keeps all savings and any incentives with you. Leases and PPAs put a company's equipment on your roof for 20-25 years, complicate a home sale, and in 2026 any tax benefits they advertise belong to the company under commercial rules - not to you. Read escalator clauses carefully.
