Home / Home solar panels
Solar panels for Illinois homes, sized to your real bill
We design rooftop solar around your roof, your sunlight and your actual electricity use, then show you owning, leasing and $0-down options side by side, with the Illinois Shines incentive built in.
01How we size a system for your home
How we size a system for your home
Every home starts with three checks before anyone visits: your roof (its size, pitch and which way it faces), sunlight and shade through the whole year, and your electric bill. From those we size the system to cover as much of your real usage as your roof allows, not a one-size package.
- Roof: south, southwest, west and southeast faces work best; east can work too.
- Shade: trees and nearby buildings are modeled hour by hour.
- Usage: your most recent bill turns the estimate into an accurate number.
02What a system makes in Illinois
What a system makes in Illinois
A well-placed kilowatt of panels on a typical Illinois roof makes roughly 1,300 to 1,450 kilowatt-hours a year. Most of that comes from spring through early fall, and every estimate we give you is modeled month by month, so shorter winter days are already counted.
Panels make power from light, not heat, and run more efficiently in the cold. Snow on a tilted, dark panel usually slides off after a day or two of sun.
03From yes to power-on
From yes to power-on
- Assessment: roof, sun and bill, before we meet.
- Proposal: own, lease or $0-down PPA, side by side, with the Illinois Shines disclosure.
- Site survey and design: a specialist confirms your roof and electrical panel in person.
- Permits and install: handled by our approved partner; most installs take a day.
- Power-on: after the city inspection and your utility's approval.
See if your home qualifies.
We check your roof's sun and shade and your electric bill first, then show which plans fit, with no cost or obligation.
04Questions
Solar panels questions
How long do solar panels last?
Modern panels are typically warrantied for 25 years and keep producing well beyond that, slowly losing a small amount of output each year. That's why we check that your roof has plenty of life left before installing.
Do I need a new roof first?
Only if yours will need replacing in the next several years. Removing and reinstalling panels later adds cost, so it's usually better to do the roof first. A specialist checks this in person before anything is signed.
Will solar work with ComEd or Ameren?
Yes. You stay connected to your utility. Your panels cover much of your power and the utility covers the rest, such as at night. How you're credited for extra power depends on your utility and when your system is connected; we always show savings under the current rules.
Can I add a battery or an EV charger later?
Yes. Tell us what you're planning and we'll design the system so it's easy to add a battery or cover an electric car later.
