What home solar costs in St. Paul - and the 2026 rules that changed the math
Think of this as the pre-quote homework for St. Paul, VA: 2026 prices by system size, the federal credit's expiration and what it means, Virginia net metering in plain words, and the sales tactics to walk away from.
Installed home solar for St. Paul 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 - St. Paul 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.
St. Paul plus 11 surrounding towns within 40 km form one installer market of about 70,090 people - quotes should not vary much by town.
St. Paul has about 835 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.
Solar pricing is unusually transparent if you know where to look: marketplace data puts the U.S. average at about $2.58 per watt installed. What varies in St. Paul is not the hardware - panels are commodities - but installer overhead, sales commissions, and Virginia's export rules. That is where quotes win or lose.

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The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025.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
A quote that beats everyone by 30% is not a bargain - it is a company pricing for survival, and in the 2026 shakeout that bet usually loses. Fair pricing sits near $2.58 a watt; what separates good money from wasted money is who is left standing to honor the warranty.
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 |

Common questions
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.
How much does home solar cost in 2026?
The U.S. marketplace average is about $2.58 per watt installed - roughly $15,500 for a 6 kW system and $31,000 for 12 kW, before any state incentives. Quotes meaningfully above that level deserve a written explanation of what justifies the premium.
Do I need a battery with my solar?
Not necessarily. Under full retail net metering, the grid effectively stores your surplus for free. Batteries earn their $12,000-16,000 price where export rates are low, outages are common, or time-of-use rates make evening self-consumption valuable.
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.
What is net metering and why does it decide everything?
It is the rule for how your utility credits electricity you export. Full retail net metering credits exports at the same rate you pay - the grid works like a free battery. Net billing or avoided-cost rules pay far less per exported kWh, which lengthens payback and strengthens the case for a home battery.
How long do solar panels actually last?
Panels are typically warrantied for 25 years of production and commonly outlive it, losing about 0.5% output per year. Inverters are the component that usually needs replacement - typically once, around year 12-15, at a few thousand dollars.
