Solar panels in Fairview Heights, IL

Fairview Heights is a St. Clair County city on Ameren's grid, home to the St. Clair Square shopping mall since 1974.

Most homes in Fairview Heights 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 Fairview Heights 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 Fairview Heights, including ZIP code 62208.

Check these before you sign with any solar company serving Fairview Heights:

• 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 City of Fairview Heights.
• 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.
