Frequently Asked Questions About Home Solar in Mount Vernon

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

1What is the average cost of a home solar system in Mount Vernon, IL, and are there any local incentives?

For a typical 6-8 kW system in Mount Vernon, the gross cost before incentives is usually between $18,000 and $28,000. Crucially, you can claim the 30% federal solar tax credit, which significantly reduces the net cost. While Illinois' state-wide Adjustable Block Program (solar renewable energy credits) is currently closed to new residential applications, Mount Vernon homeowners should check with Ameren Illinois for any local rebates or net metering policies that provide bill credits for excess energy sent back to the grid.

2How does Southern Illinois' climate, with its four distinct seasons, affect solar panel production?

Solar panels work efficiently in cold, clear weather and actually produce well in Mount Vernon's climate. Summer offers the most peak sun hours, but spring and fall are also very productive. Snow in winter can temporarily reduce output, but panels are installed at an angle to help shed snow, and the cold improves panel conductivity. The key metric is "peak sun hours," and Mount Vernon averages about 4.2 daily, which is very suitable for solar energy production.

3What should I look for when choosing a solar installer in the Mount Vernon area?

Prioritize installers who are licensed, insured, and have strong local experience in Jefferson County. They will understand specific permitting requirements with the City of Mount Vernon and interconnection processes with Ameren Illinois. Ask for references from nearby past customers, verify their certifications (like NABCEP), and ensure they provide a detailed production estimate specific to your home's roof orientation and local shading factors.

4How long does the entire process take from signing a contract to turning the system on in Mount Vernon?

The entire process typically takes 2 to 4 months. This timeline includes system design, securing permits from the City of Mount Vernon Building Department, ordering equipment, the physical installation (1-3 days), and the final inspection and interconnection approval from Ameren Illinois. Seasonal weather can cause minor delays, so starting the process in spring or fall can ensure a smoother timeline.

5My roof is older; should I replace it before going solar in Mount Vernon?

Yes, it is highly recommended to address any needed roof repairs or replacement before installation. Solar panels have a 25+ year lifespan, and removing them later for roof work is costly. A reputable local installer will assess your roof's condition and age during the initial consultation. Given the potential for severe weather in Southern Illinois, starting with a sound, durable roof is critical for protecting your long-term solar investment.
