Meet Dave
Dave Sonner founded Solar Power Midwest to do something most solar companies don't: verify everything before recommending anything. He has more than two decades in solar, and his companies have served 30,000+ customers since 1993. Checking first is the difference between SPM and a company that just sells a big panel count.
SPM covers commercial and farm solar, commercial battery storage, heat pumps, and ComEd Energy Efficiency Programs, and our sister company, Renovate Right 365, handles windows and siding. Your savings are real and your plan is bankable.
Real customer, real bills
Jim's winter electric bill hit $598.73. After his ground-mount system came online, the next one was $12.17.

Commercial and farm solar pays off fastest when the federal credit, depreciation, Illinois Shines and ComEd programs are stacked correctly. See the Illinois solar incentives for businesses and farms, or the ComEd rebates for heat pumps and business equipment.

FAQ
Commercial solar, farm and agricultural solar, commercial battery storage, and heat pumps across Illinois. Windows, siding and doors are handled by our sister company, Renovate Right 365. SPM no longer sells new residential solar or home battery systems, but existing SPM solar customers still get service and monitoring support.
Yes. Modern solar panels generate electricity from daylight, not direct sunlight or heat. Illinois averages 4.5 peak sun hours per day annually, and net metering credits from summer production roll over to offset winter bills.
Commercial projects involve demand charges, which residential bills do not. A solar system that reduces kWh but not peak demand may save less than expected. SPM analyzes 15-minute interval data to understand your actual load profile before sizing any system.
The ITC allows businesses to deduct 30% of the solar system cost from federal taxes. For a $500,000 system, that is $150,000 off your tax bill (not just a deduction). The credit is still available: commercial projects generally need to be placed in service by December 31, 2027 to claim the full 30%, and starting construction sooner (safe harbor) helps lock in eligibility. SPM helps you document the project for ITC eligibility and coordinates with your CPA on depreciation and Section 179 treatment.
Yes. Illinois farms typically have high daytime electricity loads (grain drying, irrigation, livestock ventilation, refrigeration, lighting, and machinery charging) that align well with solar production hours. Agricultural rate structures (ComEd AG-1, AG-2) often have demand components where solar and battery storage can reduce peak charges.
Yes. The USDA Rural Energy for America Program (REAP) offers grants that can cover a meaningful share of eligible project costs for agricultural producers and rural small businesses, and REAP grants can typically be combined with the 30% commercial ITC and bonus depreciation. REAP has its own application windows and paperwork through your local USDA Rural Development office, so SPM recommends starting that process early and confirming current award percentages and deadlines with USDA directly, since program details are updated periodically.
Often yes. Batteries can reduce demand charges, protect critical loads during outages, and add flexibility if ComEd limits export. SPM evaluates battery storage for every commercial project, not just when the customer asks.
SPM looks at how your building actually uses power, including 15-minute interval data and demand charges, before sizing any solar system. Cutting your load first often makes the system smaller and less expensive. We also stay involved long after installation. Dave Sonner, the owner, is known for checking in with customers years later.
Yes. Heat pumps are installed for homes as well as businesses. ComEd offers rebates on qualifying heat pump systems, and SPM checks which ones you qualify for. See the ComEd rebates page for current amounts.
Yes. Existing SPM solar customers keep service and monitoring support. Call (844) 497-6527 or use the customer service page.
Solar Power Midwest serves Will, DuPage, Cook, Kane, Kendall, and Grundy Counties in Illinois, including Naperville, Joliet, Aurora, Bolingbrook, and 25+ surrounding communities.
All of them across Illinois: ComEd, Ameren Illinois, municipal utilities, and rural electric co-ops. SPM handles the interconnection application and rebate paperwork with your utility, so your system gets connected and every incentive you qualify for is claimed.
ComEd credits any solar power you export to the grid against your bill, so you draw on those credits at night or on cloudy days instead of buying full-price power. Under the Climate and Equitable Jobs Act, systems interconnected after December 31, 2024 earn export credits based on the supply portion of the rate rather than the full retail rate; systems interconnected earlier generally keep their prior terms. SPM confirms your exact interconnection status before you sign.
From the Blog
Commercial solar is a different calculation than residential. This guide walks small business owners through how commercial solar is sized, what the tax landscape looks like, and when it makes sense to move forward.
For businesses facing demand charges or outage risk, adding battery storage to commercial solar can improve the economics significantly. Here's how to evaluate the combination.
Replacing a gas furnace with a heat pump shifts your heating to electricity, which solar can then offset. Here's how to think about the heat pump + solar combination and what it means for sizing.
