National Grid towns: how the utility side works
National Grid's Massachusetts interconnection tariff describes three paths for a customer's system: Simplified, Expedited and Standard. The path that applies depends on the system and your service, and the application goes through National Grid's online customer application portal, separately from the town permit. SunPol handles your building permit and utility paperwork for you.
For a home battery, National Grid's ConnectedSolutions program says customers with a qualifying battery can earn an average of $1,200 each year by letting National Grid discharge it at peak times, and Mass Save's HEAT Loan can finance a battery enrolled in ConnectedSolutions. The program runs June 1 to September 30. Check National Grid's page for the current per-kW rate. 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.
SMART, the state production incentive, 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.
Shrewsbury: SELCO's rules
SELCO has a residential net metering policy and credits the customer at the designated retail rate. It also says "You cannot enter into panel leasing arrangements or third-party power purchase agreements within the SELCO service territory." The system has to be customer-owned. SELCO's interconnection policy 3.19 (revised September 2024) has an online application with a $250 fee and a separate net-and-production meter installation fee, and covers solar with or without a battery. The building and electrical permits come from the Town of Shrewsbury. SunPol handles your building permit and utility paperwork for you.
SMART is limited to Eversource, National Grid and Unitil interconnections, and National Grid's ConnectedSolutions is for National Grid customers, so neither applies to a SELCO customer. SunPol offers a cash purchase or a loan in Shrewsbury. PPAs and the Prepaid Solar Program are not offered there.
Millbury publishes its solar inspection order
Millbury's building department has a dedicated solar section. Its rules, in short:
- All solar projects need a final electrical inspection before the final building inspection can be completed.
- In place of a rough inspection for a PV system, the installer uploads photos (rails and bonding, attic where applicable) and notifies the office.
- Trench inspections for solar still need a physical visit.
- Snow must be cleared off the roof before a building or electrical inspection.
- Inspections are requested through the office; electrical inspections run Monday, Wednesday and Friday afternoons.
SunPol coordinates these with your installation team.

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 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 Worcester-area homeowners
Is Worcester on National Grid or Eversource?
National Grid. The City of Worcester says National Grid is Worcester's only electric utility. Eversource's electric list does not include Worcester, Auburn, Grafton, Millbury or Shrewsbury.
Does the SMART incentive work in Shrewsbury?
No. SMART needs interconnection by Eversource, National Grid or Unitil. Shrewsbury's electricity is delivered by SELCO.
Can I offer my home battery to ConnectedSolutions if I am a SELCO customer?
National Grid's program is for National Grid customers. Ask SELCO about its own battery options.
Is the utility application the same as the town permit?
No. The town permit and inspections come from your building department. The utility interconnection is a separate application. SunPol handles your building permit and utility paperwork for you.
How much less does the Prepaid Solar Program cost than buying?
Your price is 30% less than buying the same system. Your free design shows your exact price and the estimated breakeven. Savings are not guaranteed. You will still get a utility bill.
Does SunPol work in Worcester-area towns not listed?
SunPol serves homeowners across Massachusetts. The consultation confirms your utility and permit office for any address.
