Assumption, a small rural community, features a stable housing market with a high homeownership rate among its 1,024 residents. The median home value is 78,300, reflecting an older housing stock, with half of homes built before 1980. The local workforce primarily commutes, with a small percentage working remotely. The economy is typical of a modest agricultural service community.
Homeowners in Assumption are paying more for electricity than ever. Ameren Illinois rates have surged and are projected to keep climbing. The fastest path to savings?

Assumption benefits from a moderate annual solar resource, with peak sun hours averaging 4.2 daily. Seasonal production is strong during summer months (June-August), gradually decreasing through winter.

Solar FAQ for Assumption
An average 5.5 kW system in Assumption costs approximately $15,125 before incentives. After the DG rebate and estimated Illinois Shines SREC (~$6,283 — starting June 2026, 50% paid as a lump sum, remaining 50% in quarterly payments over 6 years), the estimated net cost drops to around $7,192. Actual costs vary based on your home and system size.
With a solar lease, the average Assumption homeowner could save about $53/month on their Ameren Illinois bill (solar only — optional battery backup adds ~$70/mo for outage protection). That's about 46% less than your current bill — and your rate is fixed for 15 years while utility rates keep climbing.
The 30% residential ITC expired December 31, 2025 for homeowner-owned systems. However, if you lease your solar system, the installer can still claim the business ITC through 2027 and pass savings to you through lower lease payments. Call us to learn how this works.
Modern solar panels are warranted for 25 years and typically last 30-35 years. They degrade slowly — losing only about 0.5% efficiency per year.
Yes. Assumption gets 4.2 peak sun hours per day on average. Solar panels actually perform better in cold temperatures. Snow typically slides off tilted panels quickly, and the system is designed for year-round production.
RECs are measured per 1,000 kWh of solar production — more panels and more sunlight means a higher value. An average Assumption system (~5.5 kW) produces ~7,398 kWh/year = 7.4 RECs/year. Over the 15-year contract, the estimated customer value is ~$6,283 (85% of gross). Starting June 2026, 50% is paid as a lump sum after installation, with the remaining 50% in quarterly payments over 6 years. Cash/finance buyers receive this directly. Lease customers benefit through lower payments. See our REC Calculator for a custom estimate.
Studies show solar adds $15,000-$25,000 to home value for a typical residential system. In Illinois, 100% of that added value is exempt from property taxes — so you get the equity without higher taxes.
With a 30-year minimum panel lifespan and a ~5.5-year breakeven in Assumption, that's approximately 25+ years of pure profit and inflation protection. After breakeven, your electricity cost drops to near-zero while utility rates keep climbing.
Pro Tips
1
Prioritize a professional roof inspection for homes built before 1980 to confirm structural integrity and address any necessary repairs before solar installation.
2
Evaluate potential shading sources on your property, like mature trees, to maximize sunlight exposure throughout the day for optimal energy capture.
3
Consider the long-term benefits of a solar energy system as a property enhancement in a community characterized by established single-family homes.
