Why These Are the Top Home Solar Contractors in Great Lakes

** The home solar market in Great Lakes and the surrounding North Shore suburbs is mature and competitive. The average quality of providers is high, with several established local and national companies vying for business. Homeowners benefit from this competition, which drives innovation and customer service. Key market drivers include: * **State Incentives:** Illinois' adjustable block grant program, **Illinois Shines**, provides significant monetary incentives (in the form of Solar Renewable Energy Credits) that reduce the net cost of a system. * **Federal Tax Credit:** The 30% federal Investment Tax Credit (ITC) remains a powerful financial incentive. * **Pricing:** For a typical 6kW system, gross costs range from $18,000 to $25,000 before incentives. After the 30% federal tax credit and Illinois Shines incentive, the net cost can be reduced by 50% or more, making solar a financially attractive investment. * **Competition:** The market is split between large national companies (like Sunrun) that focus on financing and local/regional specialists (like CertaSolar Pros and Windfree Solar) that compete on custom design, craftsmanship, and high-performance equipment.

Frequently Asked Questions About Home Solar in Great Lakes

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

1How much does a home solar system cost in Great Lakes, Illinois, and what incentives are available?

For a typical 6-8 kW system in the Great Lakes area, the gross cost before incentives ranges from $18,000 to $28,000. Crucially, you can reduce this by 30% with the federal Investment Tax Credit (ITC). Illinois also offers a unique state incentive: the Solar Renewable Energy Credit (SREC) program through the Illinois Shines program, which provides an upfront "buy-down" payment that can significantly lower your initial cost, making net prices very competitive.

2How does the Great Lakes climate, with its snowy winters and variable sunshine, affect solar panel performance?

Solar panels are effective in cold, sunny weather and actually operate more efficiently in cooler temperatures. While winter days are shorter and snow cover can temporarily reduce output, panels are installed at an angle to help shed snow. Importantly, Illinois has strong net metering rules, so the excess power your system generates during long, sunny summer days credits your utility account to offset lower production in winter months, ensuring annual savings.

3What should I look for when choosing a solar installer in Lake County, Illinois?

Prioritize installers who are licensed, insured, and have strong local experience in Great Lakes and the broader North Shore area. They should be intimately familiar with the permitting processes of local utilities like ComEd and specific requirements of the Great Lakes Naval Station community if applicable. Always check for certifications (like NABCEP) and read verified local reviews to assess their reputation for quality and customer service.

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

For a home in Great Lakes, the entire process typically takes 3 to 5 months. This timeline includes system design, securing permits from local authorities and ComEd, the physical installation (which usually takes 1-3 days), and finally the utility interconnection approval and inspection ("Permission to Operate"). Seasonal weather can cause minor delays, so starting the process in spring or summer is often ideal.

5Will solar panels increase my property taxes in Illinois, and how do they handle hail or storm damage?

No, under the Illinois Property Tax Code, a home solar installation is considered a "renewable energy device" and is exempt from increasing your property's assessed value for tax purposes. For weather damage, solar panels are highly durable and rated for severe hail. Your homeowner's insurance typically covers them, but you must notify your insurer to add the system to your policy, which usually results in only a minimal premium increase.
