Solar panels in Sherman, IL

Sherman is a Sangamon County village just north of Springfield where most homes are on Ameren Illinois and some are on Menard Electric Cooperative.

Most homes in Sherman 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 Sherman 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 Sherman, including ZIP code 62684.

• 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.

Illinois Shines, the state's solar incentive program, had approved 92 home-sized solar systems (25 kW or smaller) in ZIP code 62684 as of September 2026, including 18 in the past 12 months.

About 64% of them are owned by the homeowner, paid in cash or with a loan, and the rest are leases or power purchase agreements, compared with 44% owned statewide. The typical system is 10.0 kW, larger than the 7.6 kW typical across Illinois. To compare the two ways to pay, see solar lease vs. buy in Illinois.

Check these before you sign with any solar company serving Sherman:

• 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 Sherman.
• 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.

Yes. A battery stores your solar power and keeps chosen circuits running when the Ameren grid goes down, which standard solar alone can't do. Ameren pays about $300 per kWh of battery capacity, around $4,050 for one 13.5 kWh battery, if you enroll it in the utility's virtual power plant program.

• Essentials: one battery usually covers the refrigerator, lights, internet, sump pump and furnace fan.
• Whole home: running central air, an electric range or a well pump usually takes two or more batteries.
• Adding later: many batteries can be added to an existing solar system, so ask installers about it even if you start with panels only.
• On a private well: an outage also stops your well pump, so make sure the battery can start it. See battery backup for homes on well water.

• The village lists both Ameren Illinois and Menard Electric Cooperative as electric providers for the Sherman area, so check your bill: Ameren's solar and battery rebates apply only to Ameren customers.
• Sherman's village code limits rooftop solar in its residential districts so panels don't extend above the roof's ridge line.
• In Sherman the Village Administrator serves as Zoning Enforcement Officer and reviews all building permit applications; the village office is at 401 St. John's Drive (217-496-2621).
• Homeowners who need an exception to Sherman's zoning rules, such as a setback variance, go through a hearing before the village Zoning Board of Appeals.

4. 4

   Property tax form

   File form PTAX-330 with the Sangamon County assessment office (the chief county assessment officer) so the system doesn't raise your assessment. See how Illinois taxes homes with solar.
