Three kinds of electric utility in Hampden County

Most of the towns below are served by one of the two investor-owned utilities. Three (Chicopee, Holyoke and Westfield) have a municipal light plant that sets its own solar rules.

Eversource and National Grid customers can use net metering, and projects interconnected by either company can apply to the state's SMART incentive. With a PPA or the Prepaid Solar Program, the PPA provider or SunPol owns the system, and your agreement explains how SMART is handled. Town-owned light plants are outside both: the state's net-metering guide covers customers of "a regulated electric company (Eversource, National Grid, or Unitil)" and SMART projects must be interconnected by one of those same three companies.

The three municipal plants each handle rooftop solar differently:

  • Chicopee Electric Light credits residential systems of 15 kW or less at the full retail value, needs an approved interconnection agreement before installation, and does not allow third-party power purchase agreements.
  • Holyoke Gas & Electric says it does not offer net metering. It credits solar generation at a separate rate: $0.063/kWh in the example on its page (May 2026), against a $0.165/kWh residential rate in the same example.
  • Westfield Gas & Electric requires the solar system to be owned by the customer, with no lease or power purchase agreement, and wants an application approved before installation.

In these three towns SunPol offers a cash purchase or a loan only. PPAs and the Prepaid Solar Program are not offered there.

Permit details that differ by town

  • Palmer publishes a residential solar permit requirements sheet (10th edition, effective July 1, 2025).
  • Holyoke will not issue the electrical permit without an HG&E utility authorization number.
  • Ludlow and Wilbraham fire departments each have a photovoltaic plan review form.
  • Westfield does not accept permit applications by email. SunPol handles your building permit and utility paperwork for you.
  • Springfield's building division says permit review "shall not exceed 30 days" once the plans and documents are complete.

What is the same across Massachusetts

  • The state income tax credit is 15% of the net cost, capped at $1,000 in total for your principal residence, for systems you own.
  • Solar systems can be exempt from local property tax for 20 years (Massachusetts DLS).
  • The federal residential clean energy credit (25D) is not available for property placed in service after December 31, 2025 (IRS).
  • State zoning law (M.G.L. c.40A §3) says a town may not "prohibit or unreasonably regulate" solar energy systems, except where necessary to protect the public health, safety or welfare. Historic-district review can still apply.

Statewide detail is on the Massachusetts solar company page.

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 Eversource and 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. 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.

Hampden County solar questions

How do I know which utility serves my address?

Check your electric bill. The state's DPU has a "find my electric company" tool, and it warns that "multiple companies might serve one city or town." The table above shows what we found for each town. Where two companies are listed, the bill decides.

Can I get SMART or net metering if I live in Chicopee, Holyoke or Westfield?

SMART is limited to projects interconnected by Eversource, National Grid or Unitil, and the state net-metering guide covers customers of those three. In a municipal light plant town, ask your plant for its current policy. Chicopee, Holyoke and Westfield each publish one, summarized above.

Does SunPol offer the Prepaid Solar Program in every Hampden County town?

No. In Chicopee, Holyoke and Westfield, which have town-owned light plants, SunPol offers a cash purchase or a loan. In the other towns listed above a Solar PPA, Direct Ownership (cash or loan), Propel (where your project qualifies) or the Prepaid Solar Program can apply, depending on your address.

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.

Who handles the permits?

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. Each town's office is listed above.
