Frequently Asked Questions About Home Solar in Joliet

Get answers to common questions about home solar services in Joliet, Illinois.

1How much does a home solar system typically cost in Joliet, and are there any local incentives to help with the price?

For a typical 6-8 kW system in Joliet, the gross cost before incentives is usually between $18,000 and $28,000. Crucially, Illinois offers strong state incentives, including the Illinois Shines program which provides a fixed payment per kilowatt-hour generated over 15 years, significantly reducing your net cost. Combined with the 30% federal tax credit, the final out-of-pocket expense can be nearly cut in half, making solar very affordable for Joliet homeowners.

2How does Joliet's climate, with its snowy winters and variable cloud cover, affect solar panel production?

Solar panels are effective in cold, sunny weather and Joliet receives ample sunlight for efficient production year-round. While shorter winter days and occasional snow cover will reduce output for a period, your system is designed to account for seasonal variations. Importantly, panels are installed at an angle, so snow usually slides off, and they often generate electricity on bright, overcast days. The high production in spring, summer, and fall will offset the lower winter months, leading to substantial annual savings.

3What is the process and timeline for getting solar panels installed on my Joliet home?

From signing a contract to system activation, the process typically takes 2 to 4 months. After design and permitting with the City of Joliet and ComEd, the physical installation usually takes 1-3 days. The longest phase is often waiting for ComEd to approve interconnection and install a new net meter, which can take several weeks. A reputable local installer will manage all permits, inspections, and utility paperwork for you, streamlining the entire timeline.

4What should I look for when choosing a solar installer in the Joliet area?

Prioritize installers who are locally licensed, insured, and have extensive experience with Joliet's specific building codes and ComEd's interconnection requirements. Look for established companies with strong reviews on local platforms and ask for references from recent installations in your neighborhood. Ensure they are an approved vendor for the Illinois Shines program and provide clear explanations of warranties, production guarantees, and how net metering with ComEd works for your bill.

5As a Joliet homeowner, how does net metering with ComEd work, and what happens to my power during an outage?

ComEd's net metering policy credits you for excess solar energy sent to the grid at the full retail rate, rolling over credits month-to-month with an annual "true-up" settlement. This greatly offsets your bill for power drawn at night or on cloudy days. Standard grid-tied systems will shut off during a power outage for safety reasons, unless you invest in a paired battery storage system. Adding a battery, like a Tesla Powerwall, can provide backup power to keep essential circuits running during outages, which can be valuable during Joliet's occasional severe storms.
