Get answers to common questions about home solar services in Allendale, Illinois.
For a typical 6-8 kW system in Allendale, the gross cost before incentives ranges from $18,000 to $28,000. Crucially, Illinois offers strong incentives including the state's Solar Renewable Energy Credit (SREC) program through the Illinois Shines program, which provides an upfront payment that significantly reduces net cost. You also benefit from the 30% federal tax credit and local net metering from your utility, making the final investment much more affordable.
Allendale experiences all four seasons, with sunny summers and colder, cloudier winters. Solar production will be highest from spring through fall, with potential snow cover in winter temporarily reducing output. However, modern panels are efficient in cold, clear weather, and Illinois's overall solar resource is comparable to parts of Florida, meaning your system will generate substantial annual energy, with summer overproduction offsetting lower winter months through net metering.
Prioritize installers who are licensed, insured, and have strong experience with local permitting and interconnection processes for utilities like Ameren Illinois. Look for companies with proven installations in Wayne County and ask for local references. Ensure they are an approved vendor for the Illinois Shines program to guarantee you receive your state SREC incentive, and compare detailed proposals that include system monitoring and long-term warranty support.
The full process typically takes 2 to 4 months. This timeline includes system design, securing permits from local Allendale and Wayne County authorities, approval from Ameren Illinois for interconnection, the physical installation (which takes 1-3 days), and the final inspection and utility permission to operate (PTO). Seasonal factors like high demand in spring can affect schedules, so starting in winter or early spring can ensure your system is ready for peak summer sun.
Most asphalt shingle roofs in good condition with southern, eastern, or western exposure are excellent candidates. A reputable installer will conduct a thorough site assessment to evaluate roof angle, shading, and structural integrity. Regarding hail, solar panels installed in Illinois must meet stringent UL testing standards for impact resistance, often rated to withstand hail up to 1 inch in diameter, which is comparable to the protection offered by a standard architectural shingle roof.
