Solar FAQ for Kewanee

An average 5 kW residential system in Kewanee costs approximately $13,750 before incentives. After the DG rebate ($300/kW) and the estimated Illinois Shines REC of ~$5,309 (50% paid in the first year, remaining 50% quarterly over 6 years), the estimated net cost is approximately $6,941. Actual costs vary based on your home and system size.

We offer multiple pathways: lease or PPA with $0 down and immediate savings, solar loans (typically 6-7% APR, 15-25 year terms), or cash purchase for the best long-term ROI. We also help income-eligible homeowners access the Solar for All program (no solar payments). Call us and we'll find the best fit for your situation.

At current Ameren Illinois rates and with Illinois incentives, a typical system in Kewanee breaks even in approximately 5.6 years. That means 24+ years of pure profit and inflation protection on a system that lasts 30+ years.

Based on current rates with 6% annual escalation, a 5 kW system in Kewanee could save approximately $35,931 over 25 years. That's an estimated 293% return on your investment.

With a lease, you pay a fixed monthly amount for the solar equipment on your roof. With a PPA (Power Purchase Agreement), you pay a fixed price per kWh for the power the system generates. Both options are $0 down with no maintenance costs. The end result is similar — a lower, predictable electricity cost — but the billing structure differs slightly. We'll help you determine which option saves you more based on your usage.

At the end of your 15-year lease, you have three options: (1) Purchase the system at fair market value (often very affordable after 15 years) and enjoy $0/month electricity for the remaining 10-20 years of panel life. (2) Renew the lease on annual terms. (3) Have the panels removed at no cost — the installer removes all equipment and returns your roof to its original condition, including patching any penetration points. Most homeowners choose to purchase since the system still has decades of production life remaining.

Yes. With a solar lease, there is no upfront cost. Our trusted installer partners cover the equipment, installation, permitting, and maintenance. You simply pay a lower rate for electricity than what Ameren Illinois charges — and that rate is locked in for 15 years while utility rates keep climbing.

You'll still receive a bill from Ameren Illinois because your home stays connected to the grid. On months when your solar system doesn't cover 100% of your usage (like deep winter), you'll buy the difference from the utility. You'll also pay standard utility connection fees (~$14/mo). But your overall electricity cost should be significantly lower than before solar.

Battery backup on a 15-year lease typically covers essential circuits — your refrigerator, lights, Wi-Fi, phone chargers, and a garage door opener for approximately 8-12 hours, plus whatever the sun produces during the day. The battery automatically recharges when sunlight returns. Your installer will help you choose which circuits to back up during installation.

Your installer provides a monitoring app where you can check your system's production in real time — daily, monthly, or annually. The installer's operations team also monitors your system remotely and will proactively reach out if production drops below expected levels. On a lease, monitoring and any needed repairs are included for the full term.

No — the 30% residential ITC (Section 25D) expired December 31, 2025. Homeowner-owned systems installed in 2026 receive zero federal credit. However, lease/PPA systems can still benefit from the business ITC through 2027 — which means lower lease payments for you. Call us to learn how.

RECs (Renewable Energy Credits) are measured per 1,000 kWh of solar production — so more sunlight hours and more panels means a higher REC value. Here's how it works for an average Kewanee system: A ~5 kW system produces ~7,010 kWh/year, which equals 7 RECs/year. Over the 15-year contract (×14.2 multiplier), that's 99.5 total RECs. At $70.37/REC (Ameren IL 0–10 kW tier, 2026-2027 program year), the estimated total customer payment is ~$5,954 (85% of gross — the remaining ~15% covers vendor fees and underproduction collateral). 50% is paid in the first year after installation, with the remaining 50% in quarterly payments over 6 years. REC values went up for the new program year. Cash/finance buyers receive payments directly. Lease customers benefit through lower payments. Use our REC Calculator at /rec-calculator/ for a custom estimate.

The Distributed Generation rebate provides $300 per kW for solar installations. An average 5 kW system receives ~$1,500. Actual rebate depends on your system size. It's paid by your utility under the Clean and Reliable Grid Affordability Act.

No. Illinois provides a 100% property tax exemption for solar installations. Your home value increases, but your property taxes stay the same. File PTAX-330 with your county assessor after installation. There is no expiration date on this exemption.

Illinois Solar for All is an official state program designed to make solar energy accessible to income-eligible households. You may qualify if your household income is at or below 80% of your Area Median Income (AMI). Eligible participants enjoy no solar payments, no upfront costs, no credit check, and guaranteed savings on their electricity bill. Learn more at illinoissfa.com.

Yes. Kewanee gets 4.1 peak sun hours per day on average — more than enough for solar. Panels actually perform better in cold weather. A 5 kW system produces approximately 7,010 kWh per year, covering about 82% of the average household's usage. Kewanee experiences distinct seasonal weather. Winter brings shorter days and lower sun angles, reducing solar output compared to the high production months of summer. While snowfall can temporarily cover panels, systems are designed for snow shedding. The annual solar resource of 3.95 kWh/m²/day indicates robust year-round potential despite these seasonal fluctuations.

Modern solar panels are warranted for 25 years and typically produce power for 30-35 years. They degrade slowly — about 0.5% per year. After 25 years, panels still produce around 87% of their original output.

Standard grid-tied solar systems shut off during outages for safety (to protect utility workers). If you want backup power, add a battery system — the $300/kWh DG rebate helps with cost, and the upcoming Virtual Power Plant program adds revenue potential.

Very little. Rain handles most cleaning. Occasional inspection and inverter replacement (after 10-15 years, ~$1,500) are the main costs. No moving parts means minimal wear and tear.

Most roofs can. Solar panels add about 3-4 pounds per square foot. Your roof should be in good condition with at least 10 years of life remaining. South-facing is ideal, but east/west work well too. We assess your roof in the free consultation. Given Kewanee's housing characteristics, where the median home age is approximately 1955 and over half of homes pre-date 1980, a thorough roof inspection is essential. Single-family homes offer suitable surface area, but structural integrity and the remaining lifespan of the roofing material must be confirmed to ensure suitability for a long-term solar installation.

From signing to system activation, the typical timeline is 6-12 weeks. The actual installation takes 1-2 days. Most of the time is spent on permitting, utility interconnection, and Ameren Illinois approval. Installation timelines in Kewanee typically involve initial consultation, site assessment, system design, permitting, and physical installation. As a small town with a developing solar market, the local administrative processes for permits are generally straightforward, contributing to an efficient project flow from start to completion, often within a few months.

You should be available for the initial site survey and final walkthrough, but you don't need to be home during the full installation. The crew works on your roof and at your electrical panel.

Solar increases home value by $15,000-$25,000 on average (tax-exempt in IL). Owned systems transfer with the property. Leased systems may need the lease transferred to the new owner — most buyers see solar as a positive since it means lower bills. In Kewanee's real estate market, characterized by a median home value of 63,400, adding solar can be a significant property enhancement. Such upgrades are generally viewed positively, potentially increasing property appeal and marketability. This aligns with the community's high homeownership rate, where residents are invested in long-term property improvements.

New systems receive credits at the supply rate only (~6-8¢/kWh) for excess energy sent to the grid. Credits roll forward month to month and never expire. This is why we size systems to match your usage rather than overproduce.
