Get answers to common questions about home solar services in Cortland, Illinois.
For a typical 6-8 kW system in Cortland, 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 strong local incentives, including 1:1 net metering from ComEd and the Illinois Shines program, which provides additional monetary credits for the renewable energy your system produces, significantly improving payback time.
Cortland experiences all four seasons, with sunny summers and cloudy, snowy winters. Solar panels are highly efficient in cold, sunny weather and will produce substantial energy year-round. While winter production is lower due to shorter days and potential snow cover, Illinois's net metering policy allows you to bank summer surplus credits to offset winter usage, ensuring a reliable annual benefit.
Yes, you will need a building permit from the DeKalb County Building Department. Most installations in Illinois are protected by the Solar Rights Act, which prohibits HOAs from outright banning solar panels but may have reasonable rules on placement. A reputable local installer will handle the entire permitting process and will be familiar with the specific requirements for Cortland and DeKalb County.
Prioritize providers with strong local experience, proper Illinois licensing (like a roofing or electrical license), and a physical presence in Northern Illinois. Ask for references from nearby installations and verify they handle all aspects, including permits, interconnection with ComEd, and Illinois Shines program paperwork. Local companies are best equipped to navigate regional weather patterns and utility requirements.
Standard grid-tied systems shut off during an outage for safety, unless paired with a dedicated battery backup. For snow, panels are installed at an angle, so snow usually slides off; their dark surface also helps melt it. Light snow dusting has minimal impact, and production on clear winter days can be excellent. Your installer will design the system with our specific latitude and climate in mind.
