Illinois solar installer marketing built on the Shines handbook, not the old tax credit

Illinois Shines pays for the renewable energy credits a home system makes, and it writes its own marketing rules. A vendor that breaks them can be disciplined by the program, so the wording on your ads matters as much as the offer.

The Illinois Shines consumer protection handbook for the 2026-27 program year names the problem phrases. The program is never a "rebate" or a "tax credit". Under the Shines rules, an offer is "free", "no cost" or "$0" only when the homeowner owes nothing at all, with no lease payment, fee or tax bill later. A free consultation is fine. Free solar is not.

• Bill claims. "Eliminate your electric bill", "Fire your utility" and "No more utility bills" are listed as unacceptable. The buyer stays a utility customer, and any ad that talks about the utility has to say so.
• Savings numbers. A line like "You will save X% of your bill" needs a binding savings guarantee in the contract that matches it. "Lower your electric bills" needs only a good-faith basis.
• Who you are. Every website, mailer and email names the company making the offer, and the Approved Vendor if that is someone else. It also says the offer is not part of a utility program.

We read each live ad, landing page and sales sheet against that list before writing anything new. Lines that already pass stay as they are.

A homeowner who signs today does not get the bill credits a neighbor got in 2023. Any savings figure in an ad or a proposal has to use today's rules, or it oversells the deal.

Illinois's net metering law splits customers at January 1, 2025. Systems registered before that date keep full net metering for as long as the system runs. Newer ones earn credit for the supply part of the bill: energy, capacity and transmission. Delivery charges are not credited.

The handbook ties that rule to marketing. Savings claims and estimates must match how net metering works in the utility territory where the offer is made. So each proposal uses the rates of the utility on that homeowner's bill, and an ad that still promises one-for-one credit on the whole bill is out of bounds.

Batteries change the pitch. Illinois's distributed generation rebate law sets a utility rebate per kilowatt of a system's DC rating and a separate one per kilowatt-hour of storage. The base amounts step down after December 31, 2029. A battery that takes the storage rebate must join a summer program that dispatches it on weekdays from 4 to 6 p.m., June through September. Tell buyers that before they sign, not after the first July dispatch.

Summer bills set the stakes. The EIA's Short-Term Energy Outlook forecast the average June to August home bill at $176 for 2026 in the East North Central region, which includes Illinois, up 4.5% on 2025.

Illinois buyers can look a vendor up, so the proof on your site should be what the state and the program actually issue. Customer stories follow program rules too.

Every company that installs solar in the state needs certification from the Illinois Commerce Commission, under the ICC's installer certification rule. Owners installing on their own homes are the only exception. Put the certification in the footer, on the proposal cover and in the Business Profile description, so a buyer comparing quotes can confirm it without calling.

The field is crowded. The Illinois Shines data report counts 1,003 registered Approved Vendors over the program's life, and 136 of them joined in the program year that began June 1, 2026. Pages that show where your crews work, town by town, set you apart from a vendor three counties away.

Testimonials carry four conditions in the handbook. The story has to come from a real customer of the company that runs it, and it needs a line saying individual experience may differ. Paid or rewarded? Say so. A story from outside Illinois names where that customer lives, and a customer saying they eliminated their electric bill is not allowed at all, whatever the bill shows.

Before a name, face or voice goes into an ad, get it in writing. Illinois's Right of Publicity Act requires written consent for any commercial use of a living person's identity. Our reviews service asks for that release with the review.
