UI, Eversource and two Norwalk utilities
United Illuminating serves Bridgeport, Stratford and Trumbull, and also lists Easton, Fairfield and Shelton. Eversource's list names Easton, Fairfield and Shelton too, so for those three your bill decides. Every other town listed on this page is on Eversource.
Norwalk can mean three providers. Eversource lists Norwalk. South Norwalk Electric & Water serves about 7,700 customers in a 2.0-square-mile territory within the city, and the Third Taxing District serves about 4,100 customers in East Norwalk. Both are town-owned.
- South Norwalk Electric & Water's posted solar policy (effective June 20, 2018) says it does not currently permit net metering at full retail: systems must be sized to generate no more than 75% of the customer's anticipated peak demand, and net excess is bought at its wholesale cost. Confirm current terms with SNEW.
- The Third Taxing District's FAQ describes net metering as charging the customer only for the energy received minus the energy sent back; confirm current terms and meter rules with the district.
In either Norwalk district SunPol offers a cash purchase or a loan only. The Solar PPA, Propel and the Prepaid Solar Program are not offered there.

Ways to go solar in Fairfield 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.
- Prepaid Solar Program: 30% lower program price than buying the same system*, paid upfront, no monthly payments to SunPol*, 25 years of system coverage*, for systems in service by Dec 31, 2027*. You will still get a utility bill.
Homes served by a municipal electric utility can choose a cash purchase or a solar loan; the Solar PPA, Propel and the Prepaid Solar Program aren't offered there.
Prepaid Solar Program: how it compares with buying
- The Prepaid Solar Program is one price paid upfront for 25 years, with no monthly program payments: exactly 30% less than buying the same system, for systems in service by December 31, 2027.
- Estimated breakeven is about 8–10 years,
- with an estimated $30,000–$60,000 in savings over 25 years.
Savings are not guaranteed. You will still get a utility bill.
How it works
- Share your bill. About 2 minutes.
- Get your custom design. Payment options with real numbers, on a 30-minute call.
- We handle the rest. Permits, installation and utility paperwork, with UI, Eversource or a Norwalk town-owned utility depending on your address.
