Take Control of Your Electric, Hot Water, and Heating Bills
At CSI Sun Solar Store, we believe in harnessing the power of the sun to create a sustainable future for our customers in Southwest Wisconsin, Northeast Iowa, and Northwest Illinois. As a member of the North American Solar Stores retail network (NASS), we are dedicated to providing our clients with the best solar solutions tailored to their unique needs and preferences.
Our journey began as Chimney Specialists Inc. (CSI), a Wisconsin and Iowa corporation that has been working in the alternative and renewable energy fields since 1977. Over the years, we have built a reputation for excellence in providing expert advice and high-quality wood-burning, pellet, and gas fireplaces, stoves, and inserts to our clients. As we continue to evolve as a regional alternative energy provider, we have naturally expanded our offerings to include solar electric and thermal systems for residential, commercial, and agricultural clients.
