# Solar Power Midwest > Solar Power Midwest (SPM) is an Illinois solar and home energy contractor serving the Chicagoland area and surrounding communities. SPM installs solar panels, home battery storage, heat pumps, geothermal systems, energy-efficient windows, and insulated siding. The company also handles commercial and agricultural solar projects. ## What Makes SPM Different SPM's positioning is efficiency-first: lower the building's energy load before installing the right-sized energy system. Most solar companies size systems around a customer's current, often inflated, energy consumption. SPM starts with a whole-home or whole-building energy assessment to identify efficiency improvements — window replacement, insulated siding, HVAC upgrades, air sealing — that reduce the load before the solar system is sized. This leads to a smaller, less expensive solar system with a better payback period. Brand phrase: "Lower the load first, then install the right-sized energy system." ## Services - **Solar Panels** — Residential and commercial photovoltaic systems, sized to match optimized energy loads - **Home Battery Storage** — Enphase IQ Battery and Tesla Powerwall systems for backup power and solar self-consumption - **Heat Pumps** — Air-source heat pumps (including cold-climate models for Illinois winters), replacing gas heating with efficient electric heating - **Geothermal** — Ground-source heat pump systems for heating and cooling using the earth's stable temperature - **Energy Windows** — ENERGY STAR certified replacement windows, Climate Zone 5 (U-factor ≤ 0.27), reducing building heat loss - **Insulated Siding** — Continuous insulation siding that reduces thermal bridging and building envelope heat loss - **Commercial Solar** — Flat-roof and pitched-roof commercial solar for small and medium businesses, with utility rate analysis and efficiency review - **Agricultural Solar** — Farm solar for Illinois agricultural operations ## Service Area Illinois, primarily the Chicagoland area: Joliet, Naperville, Aurora, Elgin, Bolingbrook, Romeoville, Plainfield, Lockport, Mokena, Tinley Park, Orland Park, Downers Grove, Wheaton, Glendale Heights, Oswego, Yorkville, Minooka, Channahon, Shorewood, Morris, Kankakee, Waukegan, North Chicago, Zion, and surrounding communities. ## Key Principles 1. **Efficiency before solar**: Reduce the load first, then size the solar system to match the reduced load — not the current waste. 2. **Right-sizing**: A correctly sized solar system matches actual optimized energy needs. Oversizing costs more and extends payback. Undersizing leaves savings on the table. 3. **Whole-home perspective**: Windows, siding, heat pumps, and solar interact. Decisions made in sequence produce better outcomes than treating each as an isolated project. 4. **Accuracy on incentives**: SPM does not make specific claims about tax credit amounts, rebate values, or utility program terms without verifying current availability. Programs change. Customers should verify with their utility and a qualified tax professional. ## Illinois Incentive Context (Verify Before Relying On) - **Federal Investment Tax Credit (ITC)** — The residential ITC (Section 25D) expired December 31, 2025. The commercial ITC (Section 48E) deadline for construction start is July 4, 2026 (verify current law). - **Illinois Shines (IL-SREC)** — Illinois solar renewable energy credit program administered by the Illinois Power Agency. Enrollment availability and payment rates change with program blocks. Verify current status with IPA or a participating installer. - **ComEd Energy Efficiency Program** — ComEd has offered rebates on heat pumps, insulation, windows, and battery storage. Program availability and amounts change frequently. Verify directly with ComEd. - **Net Metering** — Illinois net metering allows grid-tied solar customers to receive credit for excess generation. Policies and compensation rates should be verified with the specific utility. ## Blog Content Overview SPM's blog covers solar, home energy efficiency, and building performance for both residential homeowners and commercial business owners in Illinois.
