PPA, in plain English
A Power Purchase Agreement is a long-term agreement to buy electricity generated by the solar system on your roof.
The panels generate electricity from sunlight. The PPA provider owns the system — you don’t buy the installation.
Your PPA payment is based on the system’s electricity production and the per-kWh rate in your agreement.
The PPA provider handles maintenance, service and warranty support as specified in your contract.

No guesswork
The key things to understand about solar PPA.
With a PPA, you buy the electricity generated on your roof, not the installation. The provider owns the system. You pay for the kWh it produces at the rate specified in your agreement.
Yes. Your home stays connected to the grid, and utility charges can remain. They depend on your tariff, usage and system production. Compare the combined cost of PPA electricity and utility charges with your previous electricity cost — not one bill in isolation. The figures on this page are modeled combined costs, not the amount of a single bill.
Start with your home’s usage, utility tariff, expected production, PPA rate and contractual rate-increase schedule. A year-by-year comparison helps you evaluate combined PPA and utility costs under different assumptions. The 0% and 2.99% scenarios here are illustrations, not confirmed offers. Future tariffs also affect the result. Savings are not guaranteed.
The PPA provider handles maintenance, service and warranty support as specified in the contract. Contact the provider about a system issue rather than trying to carry out technical repairs yourself. Your agreement defines the coverage and responsibilities.
A PPA may be transferable to a new homeowner, subject to the buyer’s acceptance and the provider’s transfer and qualification process. Transfer is not automatic. Your contract sets out any transfer costs and other options when selling.
We review roof condition and layout, shading and household electricity use. That helps identify installation options and any preparatory work. Eligibility also depends on your utility and the PPA provider’s requirements. Some homes will not qualify.
A standard grid-connected solar system shuts down during a grid outage to protect people working on the grid. The PPA discussed here is solar-only; backup power is not included.
Yes. We’ll walk through your bill, the proposed PPA rate, any annual rate increase and the responsibilities in the agreement in plain English. It’s a chance to ask questions and understand the cost comparison before deciding. Asking questions does not commit you to a PPA.
Your roof. An informed choice.

No upfront cost means no upfront payment for the solar system, its installation or any required preparatory work. You pay for the electricity the system produces at the per-kWh rate in your PPA, and utility charges can remain.
“Save up to 50%” compares the illustrative 16¢/kWh starting PPA rate with the average utility cost per kWh at a $250 monthly bill in our examples: about 37¢/kWh in Massachusetts (about 57% lower) and about 25¢/kWh in Connecticut (about 35% lower). In the same examples, the modeled first-year combined energy cost, including remaining utility charges, is about 49% lower in Massachusetts and about 18% lower in Connecticut. It is a per-kWh rate comparison, not a promise that your total electricity costs fall by 50%. Your proposed PPA rate and any annual increase, your utility tariff and your usage determine actual results. Savings are not guaranteed.
This is an illustration, not a personalized offer. A comparison for your home requires usage data, your utility tariff and the terms of a proposed agreement.
Monthly figures are first-year averages including PPA and modeled remaining utility costs, not the amount of one invoice.

Both scenarios assume utility prices rise 3% per year. That is an assumption, not a forecast. Annual PPA rate increases are shown separately.
Both scenarios start at an illustrative 16¢/kWh PPA rate. Neither scenario is a confirmed offer at that price. Your proposal may differ.
Positive values represent modeled savings; negative values represent a higher cost than without PPA. All amounts are nominal, without discounting — not present values, forecasts or guarantees.
The starting bill is $250/month, corresponding to approximately 12,221.68 kWh/year for CT. Usage stays constant.
The starting bill is $250/month, corresponding to approximately 8,009.34 kWh/year for MA. Usage stays constant.
First-year production is 120% of usage and falls by 0.25% annually. Assumed 3% annual growth applies to utility energy prices, surplus credit rates and fixed utility charges; the CT production-based charge does not grow. The PPA rate increases independently by 0% or 2.99% annually, starting in year 2.
The simplified annual energy balance ignores seasonality and the timing of usage and exports. Credits carry forward, with no cash payout. The model applies credits to energy shortfalls, fixed charges and then CT production charges. This reproduces the source model, not a certification of utility billing rules. Actual bills, taxes and non-offsettable charges may differ. Program and netting eligibility are not guaranteed for 25 years.
We sum unrounded annual cost differences, without discounting — not year-one savings multiplied by 25. No batteries, subsidies or tax credits are included. This model comes from SunPol calculator snapshots dated October 7, 2026 and the named Eversource references above. It is not an offer or savings guarantee.

The provider owns the system. You pay for the electricity it produces under a long-term PPA. Your agreement sets the per-kWh rate, any annual increase, maintenance and service coverage, and transfer terms. Utility charges can remain.
Final eligibility requires review; a conversation alone does not confirm qualification. Some homes need additional work or will not meet requirements. Service is limited to eligible Connecticut and Massachusetts homeowners, not every home or utility.
Transfer at a home sale is subject to the provider’s process, qualification requirements and the buyer’s acceptance. It is not automatic. Your contract defines any costs and alternative options.
Informational material only, not an offer or contract. The individual agreement controls. Savings are not guaranteed.
