What home solar costs in Haverhill - and the 2026 rules that changed the math
Solar quotes in Haverhill look very different in 2026: the federal 30% credit expired at the end of 2025, so the math now runs on real prices and Massachusetts's own rules. This guide lays out both, town by town.
Installed home solar for Haverhill 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 - Haverhill systems completed in 2026 get $0 from it.
Under Massachusetts's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Haverhill plus 12 surrounding towns within 40 km form one installer market of about 782,584 people - quotes should not vary much by town.
A fair 2026 solar decision in Haverhill needs three numbers side by side: the installed price (compare against $2.58 a watt), your utility's export rate under Massachusetts rules, and your actual daytime usage. Miss any one and the payback estimate on a sales slide is fiction.
Haverhill has about 68,291 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 Massachusetts 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The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025.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.
Massachusetts rules that decide your payback
| Rule | Massachusetts status |
|---|---|
| Export compensation (net metering) | Full-value net metering: a residential solar facility of 25 kW or less is a 'nameplate cap exempt' Class I facility that earns standard net metering credits on 100% of net excess generation valued at the utility's per-kWh basic service, distribution, transmission and transition charges (about 27 cents/kWh in a published Eversource R-1 example), and credits never expire and roll over to the next billing period. |
| State incentive | SMART 3.0 (Solar Massachusetts Renewable Target, 225 CMR 28.00) - Program Year 2026 opened January 1, 2026 with 600 MW AC of capacity and pays systems 25 kW AC or smaller a flat $0.03/kWh ($0.06/kWh for Low-Income) for a 20-year term; plus the state Residential Energy Credit (Solar and Wind Energy Credit) worth 15% of net expenditure up to $1,000 against personal income tax |
| Sales tax on the system | Exempt |
| Property tax on added home value | Excluded |
Massachusetts caps how much net metering each utility may host, but residential systems of 25 kW or less are 'nameplate cap exempt' and can net meter even when the utility's cap is full - a meaningful advantage over larger systems; separately, solar above 25 kW gets only 'market' net metering credits worth 60% of net excess generation.

Why only these platforms
The cheapest bid per watt is not the best bid. Panel warranties run 25 years, but the workmanship warranty dies with the installer - and the post-credit shakeout is closing solar companies every month in 2026. The best quote comes from the company that will still answer the phone in year five.
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 Haverhill
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 Massachusetts 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

Common questions
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.
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.
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.
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.
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.
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.
