Stateline Solar

Stateline Solar is a family-owned and operated solar energy company based in Lena, Illinois. Founded in 2017 by Ethan Fiene—making it Stephenson County’s first dedicated solar provider—the company serves Northern Illinois, Southern Wisconsin, and Eastern Iowa with comprehensive renewable energy solutions for residential homes, businesses/commercial properties, and agricultural operations. Stateline Solar distinguishes itself through its local roots; the team consists of community members who prioritize customer care beyond system lifespans.
The company offers turn-key services that include everything from initial consultation to design/engineering/permitting/installation as well as ongoing maintenance—ensuring customers have a seamless experience throughout their transition to clean energy. In addition to traditional grid-tied photovoltaic systems that customers own outright (not lease), Stateline Solar provides battery backup options for resilience during outages and EV charging stations for electric vehicles.
Their approach emphasizes transparency and education over high-pressure sales tactics; they tailor each solution to local needs while helping clients maximize incentives such as federal tax credits and state programs like SRECs or Focus on Energy rebates. With over 450 satisfied customers reported as of 2025—and more than $3.8 million awarded via SRECs—the firm has established itself as a trusted regional leader committed to long-term relationships with its clients.
