Ways to go solar in Middlesex County
- Solar PPA: pay for the power from 16¢/kWh† for qualified customers, no upfront system cost, yearly increase 0% to 2.99%†. You will still get a utility bill.
- Direct ownership: cash purchase or loan, same price; you own the system, with SunPol's 10-year workmanship warranty.
- Propel: always loan-financed; SolSource owns the system first and a prefunded Early Buyout is applied after Contract Year 5 unless you opt out§. Project and lender approval required.
- Batteries: Tesla Powerwall 3 with a Solar PPA, direct ownership or Prepaid; FranklinWH aPower 2 with direct ownership; Enphase IQ Battery 10C with Propel. 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. Backup for your essential circuits; run time depends on your usage and battery size. You will still get a utility bill.

We found no town-owned electric utility serving any town on this page, so town-owned-utility limits don't apply here; your consultation confirms what your home qualifies for.

Middlesex County solar questions
Which electric company serves my Middlesex County address?
Eversource, for every Middlesex County town listed on this page. Your bill confirms it.
I live in Higganum, Moodus or Ivoryton. Which building office do I use?
Your town's. The state's list of building officials sends Higganum to Haddam, Moodus to East Haddam, Rockfall to Middlefield, and Centerbrook and Ivoryton to Essex.
Do historic districts block solar in Middlesex County?
Not by themselves. In a local historic district a commission reviews exterior changes, but under C.G.S. §7-147f it may not deny a solar energy system unless it finds the system cannot be installed without substantially impairing the district's historic character and appearance. It may attach stipulations on design and location.
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. The licensed electrician on your installation team files the electrical permit. Several Middlesex County towns have part-time offices that may keep limited hours; we confirm with each town.
