Get answers to common questions about home solar services in Janesville, Wisconsin.
A typical residential solar system in Janesville ranges from $15,000 to $25,000 before incentives, depending on system size and home energy needs. Crucially, you can reduce this cost by 30% with the federal Investment Tax Credit (ITC). Additionally, Wisconsin offers a state sales tax exemption on solar equipment, and while Focus on Energy rebates vary, they can provide further savings. Your local utility, Alliant Energy or Rock Energy Cooperative, also offers net metering, which credits you for excess power sent to the grid.
Solar panels are very effective year-round in Janesville. They generate electricity from light, not heat, and cold temperatures can actually improve panel efficiency. Snow typically melts quickly off the dark, angled panels, and any light reflected off the snow can even boost production. While winter days are shorter, your system is designed to produce more than enough in sunnier months to build credits through net metering, offsetting your lower winter production.
In Janesville, your chosen installer will typically handle all necessary permits. This includes a building permit from the City of Janesville Development Services and an electrical permit. They will also manage the interconnection agreement with your utility (Alliant Energy or Rock Energy Cooperative) to ensure your system is properly connected to the grid. Wisconsin has strong solar access rights, protecting your system from most restrictive covenants that would block sunlight.
Look for installers who are licensed, insured, and have North American Board of Certified Energy Practitioners (NABCEP) certification. Ask for local references and examples of past installations in Rock County. A reputable company will provide a detailed site assessment, explain production estimates specific to Janesville's climate, and offer warranties on both equipment and workmanship. Checking reviews and their standing with the Wisconsin Better Business Bureau is also recommended.
No, in Wisconsin, the added value from a solar energy system is exempt from property taxes for residential properties. This is a significant state benefit. Regarding insurance, you should notify your homeowner's insurance provider of the installation. Most policies will cover the system, but you may need a slight increase in your coverage limit to account for the new asset, which typically results in a minimal premium increase.
