Get answers to common questions about home solar services in Oswego, Illinois.
For a typical Oswego home, a 6-8 kW solar panel system costs between $18,000 and $28,000 before incentives. Crucially, Illinois homeowners benefit from the state's Solar Renewable Energy Credit (SREC) program through the Illinois Shines program, which provides an upfront payment that can reduce your net cost by 30-40%. Combined with the 30% federal tax credit, this makes solar significantly more affordable in our area.
Solar panels are efficient in cold, sunny weather and Oswego receives ample annual sunlight for a strong return. While winter snow can temporarily cover panels, their slick, angled design promotes quick shedding, and they still generate power on cloudy days. System sizing accounts for seasonal variation, ensuring you generate surplus credits in sunny months to offset usage during shorter, cloudier winter days through net metering with your utility.
Installation requires a building permit from the Village of Oswego Community Development Department. Your chosen, reputable installer will typically manage this entire process. They will ensure the system meets all local building and electrical codes, including specific requirements for roof load and structural integrity, which is important given our regional snow loads. They will also coordinate the interconnection agreement with your utility (e.g., ComEd).
Choose a provider with extensive local experience in Oswego and Kendall County, as they will be familiar with specific permit processes and utility requirements. Always get multiple quotes, verify they are licensed and insured in Illinois, and check for strong warranties. Major red flags include high-pressure sales tactics, refusing to provide detailed written proposals, or lack of verifiable local references and project portfolios.
Through Illinois net metering law, ComEd credits you for excess solar energy sent to the grid at the full retail rate, rolling over credits month-to-month. Your annual "true-up" settlement is in May. Importantly, standard grid-tied systems shut off during a power outage for safety unless paired with a dedicated battery backup system, which is an increasingly popular add-on in Oswego for energy resilience.
