All seven towns are on National Grid's Massachusetts electric list, none appears on Eversource's Massachusetts electric list, and none is on the state's list of municipal light plants. Your bill is the final check.
What National Grid towns mean for the utility application
Eversource customers file through Eversource's PowerClerk portal. In these seven towns the interconnection application goes to National Grid under its Massachusetts interconnection tariff instead. The town permit is a separate step with a separate inspector. SunPol handles your building permit and utility paperwork for you. Both are needed before your system is switched on.
Solar rules each town publishes
- Charlton: "Effective June 1, 2025, the following information is required for all building permit applications for roof mounted solar projects." The sheet asks for stamped plans, roof photos, an engineer's letter and fire department review. It also states that no energy storage system will be allowed in basements.
- Oxford: solar electrical inspections are held Wednesdays between 2:00 and 4:00 pm, and requests must be received at least 24 hours in advance.
- Spencer: rooftop solar goes on the one- and two-family building permit; ground-mount solar arrays are listed under the commercial permit. That matters if you are thinking about a ground mount on a larger lot.
- Sturbridge, Dudley, Southbridge and Webster: online portals, no solar-only page found, so your electrical and building permits follow the standard process. SunPol handles your building permit and utility paperwork for you. The licensed electrician on your installation team files the electrical permit; SunPol prepares and coordinates the paperwork.
Renters and owners across the towns
SunPol designs for homeowners only. Census QuickFacts puts owner-occupancy near 86% in Sturbridge and 85% in Charlton, but at 43% in Southbridge and 60% in Webster. If you rent, we cannot design a system for your address.
Ways to go solar here
Where your utility allows it, you can go solar three ways. Solar PPA: our financing partner owns the system, you pay for the electricity it produces, and solar + Tesla Powerwall 3 is available. Direct Ownership (cash or loan): you buy the system with cash or a solar loan through our lending partners (subject to lender approval), with a Tesla Powerwall 3 or FranklinWH aPower 2 if you add a battery. Propel, where your project qualifies: always loan-financed; a potential, project-specific 25–35% lower program price than a cash purchase; requires Enphase equipment. You will still get a utility bill with any option.
A home battery on its own: a 10- or 12-year Tesla Powerwall 3 lease through our financing partner, or a cash or loan purchase of a Tesla Powerwall 3 or FranklinWH aPower 2.
With SunPol, the homeowner receives the battery incentives in Connecticut and Massachusetts, whether you buy with cash or a loan or use our financing partner's lease or PPA. In Connecticut, the Energy Storage Solutions enrollment incentive is deducted from the lease price. Incentive amounts are quote-specific. Battery incentives are not currently available for the Enphase battery in Propel. With the Prepaid Solar Program, your agreement explains how incentives are handled.
In these National Grid towns the Prepaid Solar Program is one price, paid upfront, for a 25-year term with maintenance and monitoring included and no monthly program payments. Your price is exactly 30% less than buying the same system, and your system must be in service by December 31, 2027 to qualify for this SunPol offer. Estimated breakeven is about 8–10 years, with an estimated $30,000–$60,000 in savings over 25 years. Your free design shows the numbers for your home. Savings are not guaranteed. You will still get a utility bill.

Questions from South Worcester County homeowners
Which electric utility serves Sturbridge, Charlton and the other towns here?
National Grid, according to National Grid's town list. Eversource's electric list and the state's municipal light plant list do not include these towns. National Grid's list is an older document, so confirm with your bill.
Can I put a battery in my Charlton basement?
Charlton's solar permit sheet says no energy storage system will be allowed in basements, and the fire department reviews roof-mount solar and storage plans. Tell us where you would like the battery and we will design around the rule.
Can I install a ground-mount array in Spencer?
Spencer lists ground-mount solar arrays under its commercial permit form. We confirm the route for your lot during the design.
Why does Oxford schedule solar inspections on Wednesdays?
The Building Department sets a Wednesday 2:00–4:00 pm window for solar electrical inspections. Requests need 24 hours' notice, and SunPol coordinates them with your installation team.

SMART is open to National Grid customers. With a PPA or the Prepaid Solar Program, the PPA provider or SunPol owns the system, and your agreement explains how SMART is handled.
