Solar can greatly reduce the energy portion of a bill, but most grid-connected homes still receive a utility statement with fixed charges. Your proposal should show expected production, remaining utility costs, and assumptions clearly.

Your home stays connected to the grid. When panels produce less than you need, the grid supplies the difference. When they produce more, your utility's current export-credit rules determine how that energy is credited.

Yes. Panels generate from light, not heat. Production is lower during shorter winter days, so a quality design models a full year of weather and usage rather than promising the same output every month.

It depends on cash flow, tax position, ownership goals, and how long you expect to stay in the home. We compare options side by side so you can see the tradeoffs before choosing.

The physical installation is often completed in a few days. The full process takes longer because design, permits, utility approval, inspection, and permission to operate happen before and after installation.

Owned systems typically transfer with the property. Loans, leases, and power-purchase agreements have different transfer terms, so those details should be reviewed before you sign.

No. South-facing roofs are often productive, but east- and west-facing planes can also work well. Pitch, shade, usable area, equipment, and your energy pattern all matter.

Illinois Shines supports qualifying projects through Renewable Energy Credit contracts. Utilities may also offer distributed-generation or storage rebates. Eligibility, values, and customer economics vary by project and can change.
