The area experiences distinct seasonal solar production, with strong summer months (July GHI 6.34 kWh/m²/day) and lower winter output (December GHI 1.52 kWh/m²/day).

The flat terrain typical of Central Illinois and rural lot sizes are generally favorable for system placement, while seasonal weather patterns influence production.

Solar FAQ for Colfax
An average 6.5 kW system in Colfax costs approximately $17,875 before incentives. After the DG rebate and estimated Illinois Shines SREC (~$7,205 — starting June 2026, 50% paid as a lump sum, remaining 50% in quarterly payments over 6 years), the estimated net cost drops to around $8,720. Actual costs vary based on your home and system size.
Your savings depend on roof layout, usage, and whether you include battery backup. For Colfax, our model estimates a lease payment around $116/month against an average Ameren Illinois bill of $126/month. A custom quote compares lease, cash purchase, and Solar for All to find the best monthly and long-term outcome.
Installation can occur year-round. Spring and fall offer moderate weather conditions, which can facilitate work and minimize weather-related delays. While summer provides peak solar resource, winter installations are also feasible, though lower solar intensity means less immediate production.
The process typically involves site assessment, design, permitting, and utility interconnection. As a smaller community, local permitting processes may be streamlined compared to larger cities, but standard timelines for approvals and installation should still be anticipated.
Given the median home age of 1955 and 45.3% of homes built before 1980, ensuring roof structural integrity and condition is a primary consideration for residential systems. The prevalence of single-family homes simplifies system integration and design.
Solar production naturally varies with the seasons. Summers offer the highest GHI, while winter months see reduced output due to shorter days and lower sun angles. Snowfall, when present, can temporarily cover panels, affecting immediate production until clear.
RECs are measured per 1,000 kWh of solar production — more panels and more sunlight means a higher value. An average Colfax system (~6.5 kW) produces ~8,483 kWh/year = 8.5 RECs/year. Over the 15-year contract, the estimated customer value is ~$7,205 (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.
In a community with a median home value of 117,800 and high homeownership, adding well-integrated systems can enhance a property's appeal. Modernizing homes in this established market with new features may be viewed positively by prospective buyers.
With a 30-year minimum panel lifespan and a ~5.8-year breakeven in Colfax, that's approximately 24+ years of pure profit and inflation protection. After breakeven, your electricity cost drops to near-zero while utility rates keep climbing.
Pro Tips
1
Assess the condition of older roofs, especially for homes built before 1980, to ensure they can support a system and avoid future repairs.
2
Consider the potential for optimal system placement on properties, utilizing the typically larger lot sizes found in this rural setting for ideal sun exposure.
3
Account for significant seasonal variations in solar energy production, with peak output occurring during the longer, sunnier summer months.
