About SPM
We Don't Quote Panels.
We Build Energy Plans.
Solar Power Midwest has been helping Illinois homeowners and businesses cut energy costs since the early 1990s. We do it differently — by verifying every number, claiming every incentive, and giving you a plan your lender can rely on.

How We Work
What Makes SPM Different
Verify Everything
We read your actual electric bill. We check your roof, your shading, your HVAC. Competitors skip this — we built our reputation on it.
Every Incentive, Claimed
Federal tax credit, Illinois SREC program, ComEd Energy Efficiency rebates — we make sure you get every dollar you're entitled to.
Built for the Long Haul
We coordinate with your CPA and lender, produce bankable documentation, and give you a 30-year plan — not just a panel count.
Full Energy Stack
Solar, batteries, heat pumps, energy windows, and siding — all under one contractor. One relationship. One accountability.
