Homeowners in Granville benefit from the presence of several highly reputable, multi-state companies that service the area.

Get answers to common questions about home solar services in Granville, Illinois.
For a typical 6kW to 8kW system in Granville, homeowners can expect a gross cost between $18,000 and $28,000 before incentives. Crucially, Illinois offers strong incentives including a 30% federal tax credit, the Illinois Solar Renewable Energy Credit (SREC) program which provides ongoing payments for energy produced, and a state property tax exemption for the added home value from solar. These can reduce your net cost by 40-50%.
Granville's four-season climate is excellent for solar. While winter snow can temporarily reduce output, panels are installed at an angle to help snow slide off, and the cold actually improves panel efficiency. The abundant summer sun generates significant surplus energy, which you can bank via net metering with your utility (like Ameren Illinois) to offset winter usage, ensuring year-round savings.
Yes, you will need a building permit from the Village of Granville. A reputable local solar installer will typically manage this entire process for you, including submitting the electrical and structural plans. They will also handle the interconnection agreement with Ameren Illinois, which is required to connect your system to the grid and participate in net metering.
Prioritize providers with strong local experience in the Illinois Valley. They should be familiar with Granville's specific permitting, Ameren Illinois's interconnection rules, and optimal designs for our climate. Check for Illinois-licensed electricians, strong warranties, and ask for references from recent local installations. A trustworthy provider will offer a detailed production estimate specific to your roof's orientation and Granville's weather patterns.
Professional installers use a racking system mounted to your roof's rafters, not the shingles, with waterproof flashings to prevent leaks. The installation does not compromise your roof's integrity. For maintenance, Granville's rain typically keeps panels clean, and occasional heavy snow will slide off. You should simply ensure falling leaves or debris are cleared and schedule an annual inspection, which many local providers offer.
