We've been real happy with our solar install from Full Spectrum. Our system, with 20 panels, was installed in mid 2017. They predicted a payback period of 9-10 yrs, but we expect the payback period to be 13-14 years (or a little less if rates keep going up). In their analysis they greatly overestimated production for Oct-Feb, but underestimated for the remainder of the year Unfortunately the low angle of our roof and trees to the south reduces our power output from Nov-Feb. We had 2 faulty optimizers early in - these were promptly replaced by FS.

After researching a while and getting a number of quotes, we decided to go with Full Spectrum Solar in 2017 for our 26 panel install. Burke was great to work with and very knowledgeable regarding MGE's time of use rates. He was very helpful in explaining the benefits of changing over to time of use and doing the paperwork to get our rate plan changed with MGE. The installers did a great job as well. Coming up on year 8 with no issues whatsoever. Very happy with Full Spectrum Solar and will almost certainly have them back if we decide to expand our solar array or install a battery backup system.

Burke was able to coordinate with the roofers and finish the job on time. He recommended that I replace a tall tree with a shorter one to eliminate shade on the panels. In the end, I was happy with the look of my roof and garden

Full Spectrum Solar was one of the first of its kind in Dane County. In the early days they installed solar hot water systems. Since the early 2000's they moved more aggressively into PV. When installing our PV system they designed it for maximum return given local utility restrictions and maximum return given surrounding vegetation, trees, and roof orientation

Full Spectrum noticed there was a disruption in my solar service and proactively came out to fix it. It wasn’t even their fault, my siders accidentally disconnected the solar when putting on new siding. I’m very thankful that Full Spectrum caught the problem and fixed it!

Full Spectrum has now done two projects for me. The first was seven years ago, and the second project was last year. Both systems function perfectly. His team are great.

Full Spectrum has taken such good care of us and our solar panel system since the summer of 2017! Not only did Burke and his team do a great job with installation, they also have responded promptly whenever we have questions. Finally, the team reviewed our system to ensure it was functioning properly even when we didn’t reach out. If we ever move, we will certainly use Full Spectrum again!!
