What would a solar estimate look like for a Godfrey home?
Estimates for Godfrey homes at four common bill sizes. Bigger bills need bigger systems that cost more up front, but payback stays about the same, because the Ameren rebate and Illinois Shines grow with system size too. Systems over 10 kW get somewhat different Illinois Shines prices, so treat the largest size as a rough guide. For prices by system size, see how much solar costs in Illinois.

|---|---|---|---|---|---|
| $100/mo | 4.8 kW | 12 | ~250 sq ft | $7,000 | 8.4 yrs |

How does solar work with Ameren in Godfrey?
Godfrey is a mostly owner-occupied Madison County village next to Alton, with its own solar permit application.
Most homes in Godfrey get their electricity from Ameren Illinois. That matters for solar, because your utility sets how you're credited for the power your panels send back to the grid and pays the state-required solar rebate.
For systems connected since 2025, Ameren credits exported power at the supply rate, so the best Godfrey systems are sized to cover what your home uses during the day. In exchange, Ameren pays about $300 per kW up front for systems with a smart inverter. See the full Ameren solar guide.
These estimates apply to homes with mailing addresses in Godfrey, including ZIP code 62035.

Is your Godfrey home a good fit?

- You own the home. Rooftop solar requires owning the roof.
- Your roof gets sun for most of the day on its south, west or east side, without heavy tree shade.
- Your roof has some life left. Replacing worn shingles before installing saves a removal fee later.
- Your Ameren bill is regularly over about $100 a month, or you're adding an EV or heat pump.

How do I choose a solar company in Godfrey?
Check these before you sign with any solar company serving Godfrey:
- Illinois Commerce Commission certification. Installers need the state's distributed generation installer certification for your system to be net metered.
- Illinois Shines Approved Vendor or Designee. Only registered companies can pass along the Illinois Shines incentive. Look them up on illinoisshines.com and make sure they aren't suspended.
- Local registration. Many Illinois towns require contractors to be licensed or registered locally, so ask whether the company is set up to pull permits with the Village of Godfrey.
- Two or three quotes compared on price per watt, equipment, warranties and how each handles the Ameren rebate. Our solar quote checker flags high prices, and what a quote should include walks through each line.
- No pressure. Walk away from same-day signing deadlines, "free solar" pitches and quotes that still subtract the expired federal tax credit. See spotting solar scams.
