NOI Solar · FAQ

Straight answers about home solar.

If your question is not here, call (203) 903-4091 or send it with your bill.

Can I still get the 30% federal tax credit?

Not for a system you own that is installed in 2026. The federal residential clean energy credit (Section 25D) ended for systems installed after December 31, 2025. We do not count it in your numbers. State and utility programs still apply, and in Connecticut they are significant. See incentives.

How much does home solar cost?

A typical 8 to 12 kW home system runs $25,000 to $40,000 before incentives. Your roof, shade, equipment and usage move that number, so your written review gives you a price for your home before anyone asks you to sign.

How long from signed contract to a working system?

47 days on average. About 7 to 10 days for the site visit and design, 20 to 30 days for permits and the utility application, one day on the roof for most systems, and 5 to 15 days for the utility's permission to operate.

Do you use subcontractors?

No. Every install is done by our own crews, employees on our payroll. The crew lead who walks your roof at the site visit is the crew lead who installs your system.

Which states do you serve?

All six New England states: Connecticut, Massachusetts, Rhode Island, New Hampshire, Maine and Vermont. License numbers are on every quote and contract.

How do I pay for it?

Pay cash, or we help you finance it through our financing partners or a lender you choose. Either way you own the system. We do not offer leases or power purchase agreements. Getting a quote never needs a credit check. See financing.

What equipment do you install?

Tier 1 only. Panels from REC Group, Q CELLS and Silfab; Enphase IQ8 or SolarEdge HD-Wave inverters; FranklinWH, Tesla Powerwall 3 or Enphase IQ Battery 5P batteries. The exact brand is named on your proposal, and there is no substitution clause in our contract.

I already have solar. Can you add a battery?

Yes, on systems we did not install too: any brand, any age, AC or DC coupled. See battery retrofit.

Do I need a new roof first?

We check your roof in the site visit. If it is within about 12 years of the end of its life, we recommend re-roofing first, and we can do roof and solar together: one crew, one contract. See solar + roofing.

Do you service systems someone else installed?

Yes. Production drops, inverter faults, monitoring outages and panel cleaning, on any system. We file manufacturer warranty claims for you even if the original installer is out of business. See service and repair.

Does solar work through a New England winter?

Yes, with less output in the short, snowy months and more in spring and summer. We model your system over a full year on your actual roof, so the savings in your review already account for winter.

Will solar keep my lights on in an outage?

Panels on their own shut off when the grid goes down, for the safety of utility line crews. A home battery keeps the circuits you choose running: fridge, furnace blower, well pump, lights, Wi-Fi.

In Connecticut, should I choose Buy-All or Netting?

It depends on how much power you use during the day and how big your system is. Buy-All pays a fixed rate for every kWh for 20 years. Netting offsets your own use first. We model both against your real bill and show you which pays more.

What does the free review include?

A written summary for your home: a proposed system, a price, expected savings, the incentives that apply, and what to do next. You get it within 2 business days of sending your bill.
