Chicago solar company · Illinois Shines installer
Solar and a home battery on the house you already own. Buy the system and keep the Illinois incentives, or provide the roof and pay only for the power it produces. We handle design, permits, and installation.
Same house. Two ways to pay.
Either way, Cox designs it for your roof, pulls the permits, and installs it. You choose how you pay.
Option 1 · Buy
Option 2 · Power plan
Power plan is available on a qualifying agreement only. Credit and roof approval required. Rate, term, escalator, transfer, and buyout depend on the agreement you sign and on Illinois law. With a power plan, incentives go to the system owner. This is not free solar.
Residential Solar Experts
Cox Solar Solutions helps Illinois homeowners take control of rising electric bills with solar systems engineered for their roof, their usage, and today's Illinois incentive programs. You get one team from the first consultation through utility approval — no hand-offs, no surprises.
Built for the Midwest
Illinois solar has its own rules. Snow loads and freeze-thaw cycles shape how we rack and flash every array. Supply-only net metering for new ComEd and Ameren customers means the right system size matters more than ever. And Illinois Shines REC payments reward systems that are designed and documented correctly.
We design for all of it — so your system performs in January and July, and your incentive paperwork gets approved the first time.

FAQ
For many homeowners, yes. Illinois Shines pays for the renewable energy credits your system produces, ComEd and Ameren offer a one-time $300-per-kW rebate for smart-inverter systems, and Illinois law lets you keep solar from raising your property assessment. Your savings depend on your usage, roof, and utility — a free proposal shows your real numbers.
No. Cox offers two ways to pay. You can own the system (cash or a solar loan) and receive the incentives, or choose a Cox power plan: on a qualifying agreement you provide the roof and pay for the power the system produces. Credit and roof approval required. A power plan is not free solar — you still pay for power, at the rate written in your agreement.
Not for a home system installed in 2026. The residential clean energy credit (Section 25D) ended for systems completed after December 31, 2025. Businesses may still qualify for the commercial Section 48E credit under new deadlines. Consult a tax professional about your situation.
Customers interconnecting on or after January 1, 2025 receive supply-only net metering: excess solar sent to the grid earns credits against the supply portion of the bill, and those credits roll forward. Customers interconnected by December 31, 2024 keep full retail net metering for the life of their system.
Most projects take 6 to 12 weeks from signed agreement to permission to operate. The physical installation is usually one to three days; the rest is engineering, permits, incentive approvals, and utility interconnection.
Financing options such as solar loans can allow $0 down. Income-eligible households may qualify for Illinois Solar for All, which provides solar with no upfront cost. See our financing page for details.
