Solar FAQ for South Pekin

An average 5.5 kW residential system in South Pekin costs approximately $15,950 before incentives. After the DG rebate ($300/kW) and the estimated Illinois Shines REC lump sum of ~$5,505 (received ~18 months after install), the estimated net cost is approximately $8,795. 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, the typical payback period in South Pekin is approximately 6.3 years. After payback, your electricity cost drops to near-zero for the remaining 18.7+ years of the system's life.

Based on current rates with 6% annual escalation, a 5.5 kW system in South Pekin could save approximately $38,422 over 25 years. That's an estimated 269% 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 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 South Pekin system: A ~5.5 kW system produces ~7,816 kWh/year, which equals 7.8 RECs/year. Over the 15-year contract (×14.2 multiplier), that's 111 total RECs. At $66.34/REC (Ameren IL 0–10 kW tier, 2025-2026 program year), the estimated customer lump sum is ~$6,258 (85% of gross — the remaining ~15% covers vendor fees and underproduction collateral). This is paid as a single lump sum within ~14-18 months of installation. Cash/finance buyers receive this directly. Lease customers benefit through lower payments.

The Distributed Generation rebate provides $300 per kW for solar installations. An average 5.5 kW system receives ~$1,650. 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. South Pekin gets 4.4 peak sun hours per day on average — more than enough for solar. Panels actually perform better in cold weather. A 5.5 kW system produces approximately 7,815.5 kWh per year, covering about 84% of the average household's usage.

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.

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.

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.

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.
