We had a great experience with Full Spectrum Solar! Ron took advantage of our house's design and recommended an array to fully cover our south-facing garage roof. It's been very productive so far, and we're looking forward to see how well it does throughout the year!The install process was a breeze since everyone communicated well, from the electricians to the install crew. The system's functionality was explained well and we feel confident that it'll provide maintenance-free energy for many years to come.Excited to work with them again in the future to add batteries (and another array, probably)!
We worked with Full Spectrum to install solar through the MadiSUN Group Buy program. We signed in July 2025 and, despite challenging winter weather, the project was completed by December 2025; an impressive feat given their busy season.Deiter, our Project Manager, was exceptional: thorough, patient with questions, and consistently responsive. He walked us through multiple design options and kept me informed about any scheduling changes.Eric and his electricians expertly handled our electrical service upgrade, dealt with our old house's electrical complexities, and seamlessly added an EV charger during the project.Their pricing was competitive with four other quotes (local and national), but Deiter's knowledge and the company's strong local reputation made the difference. My instinct that they'd do the job right proved correct: they delivered quality work with excellent communication throughout.
Full Spectrum rocks! They had my full system installed in just 2 days. They did a great job communicating through the very long process of planning and building our new home. This is my second solar install with Full Spectrum and I would highly recommend them to anyone considering solar.
I had a great experience working with Ron and the team. Quote to final approval was a seamless process and through every step along the way Ron was quick to answer any questions I might have had. My wife and I love our new solar system and will enjoy it for years to come! If interested in Solar I would highly reccomend Ron and the team at Full Spectrum.
We were very satisfied with the installation of our solar panels. All of the Spectrum employees at our home were knowledgable and friendly and the installation was done earlier than had been promised. The explanation of the system was through and easy to understand and the app makes it easy to see how much electrical power we're generating at any point in time. We will certainly recommend Full Spectrum Solar to anyone who asks about our system.
