I am very pleased to have had Full Spectrum Solar install my residential solar system this Fall (2025). From the onset, I had a very good feeling about this local Wisconsin company when I phoned and spoke directly with one of the company’s project engineers (Brent). Rather than send a salesperson, Brent listened to my consumption needs and came out to appropriately size my home solar system with a battery backup solution. He provided me with a detailed and customized work proposal that gave me the option to choose between two solar panel models. I chose the model that offered a higher wind and snow load rating.The company's entire installation crew (Kyle, Rick, Bryan, Bernard, etc.) was very professional, highly skilled & neat. Battery storage was installed higher on my basement wall as requested to use space more efficiently. Full Spectrum Solar was very knowledgeable about local community codes & permits for successful commissioning. Permit applications with the city and WE Energies were diligently filed, and Brent maintained excellent communication with all parties throughout the project.Full Spectrum Solar has been successful in installing Enphase microinverters and backup battery solar solutions on their residential solar installations for many years. The real-time energy monitoring interface accessed through Enphase Enlighten app allows the homeowner to see and tweak their energy consumption in real-time to maximize utility savings.
Brent and the Waukesha team were timely and professional. They treated my home and property with great respect. The solar production has matched what Brent had estimated and the Enphase IQ8+ inverters deliver plenty of live information to satisfy anyone's data cravings.
We mulled getting solar for a few years and finally went forward with it. FSS and Brent were professional throughout the process and always responsive. The installation was totally professional and looks very nice. All the various people that came through from electricians to panel installers were friendly and knowledgeable.
Brent (the project manager I worked with) and the team at Full Spectrum Solar are absolutely fantastic. Communication was excellent with clear expectations about timeline and explantations of what next steps were going to be. The installers were always friendly and polite and left everything clean. Rick (the electrician) went above and beyond by painting an area that had accidentally gotten scuffed and he also put up a new outside light fixture for me. I have been so happy with the service received and with my decision to use Full Spectrum. I would not hesitate to recommend them or to use them again if I move. Kudos to the whole team.
