Some Feedback
What Our Clients Say
EXCELLENT Based on 192 reviews Posted on Google Sarah Fiske Full Spectrum Solar has done an AMAZING job of keeping their many customers informed and up to date following the major hail storm in April 2026. Ron answered all of my questions promptly, and the workers who came to the house were professional, polite and efficient in their work. I assumed my system would be down for many weeks with all the repairs it needed, but the full down time was only 10 days to accommodate for the roofing and siding work that had to happen before the re-install.Posted on Google Alan R Came out to fix wireless communication with solar system after installing new router. Very satisfied.Posted on Google DEMS PROGRESSIVES Great service. Very thorough and timely and great follow through on complicated repair project. Totally satisfied with all aspects!!Posted on Google Sandy Ennis Highly recommend! My only complaint is that my roof is too small for all the panels I wanted 😁 Ron was great from the first call and the install crew was clean, fast and respectful even when it was super hot on my roof. Looking forward to many years of solar for my family!Posted on Google Derek Binkley Full Spectrum repaired our solar panels that were damaged in a hail storm. They were able to find an innovative solution that saved us a lot of money. The installation was quick and everything is working wonderfully now.Posted on Google Prairie President Full Spectrum Solar provided exceptional service at every step in providing a 9.2 kWh solar panel system for our church. They always kept us fully informed on plans and always responded promptly to any questions.Posted on Google Kristopher Herbrand Working with Ron and the team at Full Spectrum Solar was a great experience from start to finish. From the initial quote, to the site assessment, to installation day, communication was clear and easy throughout the entire process. The team was professional, responsive, and made everything feel straightforward. Would definitely recommend them to anyone considering solar.Posted on Google Mary Ann Phalen Our solar electric installation was beautifully designed and placed by skilled employees of Full Spectrum. We were told the install would be delayed at least a month due to recent hailstorm damage and the need to remove systems to repair or replace roofs. Their existing customers clearly were serviced. When they had a cancellation they were able to do our install. Nice men to work with throughout the process.Posted on Google Elizabeth McLain Excellent work!! We were impressed with the high level of electrical knowledge allowing Full Spectrum to trouble shoot and correct a defect left by a prior vendor. R and R was completed seamlessly. We were VERY impressed with the final results. Great Crew!!
