We signed in…read moreJuly 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.

From the start the project engineer (I worked with Mark W.) and anyone I interacted with were…read morecourteous, informative, professional and efficient. The entire process to identify if the site qualified for a system (shade, sun aspect, roof strength, etc.) through to final hook up takes several months and I was satisfied with the entire process. The decision to install a PV system starts with an analysis of current electrical use to size the system appropriately. We added a complication by asking the project manager to calculate how many PV panels we'd need to add to charge an electric vehicle three times a week. That was added that into the calculations, projections and return on investment analysis. The ROI analysis was easy to understand and, from my perspective, reasonable and realistic. Throughout the process our project manager kept us informed, and walked us through paperwork to get utility rebates and group buy discounts. We further complicated the process by adding a "time of use" meter and upgrading the line to the street to 200 amp service and Full Spectrum helped coordinate that installation with our utility. They also worked well with the electrician we hired (Prana Electric, see review) to upgrade our house panel to 200 amp service and connect the solar system into the panel. I would hire Full Spectrum again, and highly recommend both the company and it's partner, MadiSun which helps educate and enroll people in solar installations.

We got four bids on our roof replacement and Sun Vault Roofing was not the lowest. I almost went…read morewith someone else, but thankfully I did not. Our house has a complicated driveway and parking situation which their crew was able to work around seamlessly. Our HOA had its own approval layer on top of the city permit, and Sun Vault Roofing helped us navigate a two-week back-and-forth over approved shingle colors (side salad: ridiculous that HOAs have this kind of bureaucracy). Despite the complications, Sun Vault Roofing kept us updated through every delay and milestone without us having to chase anyone down. That alone was worth the price difference. The crew showed up on time, worked two full days, and left the yard cleaner than they found it. The roof has now been through 2-3 major storms since installation, including the crazy hail in April and there is not a speck of damage. Everything looks sharp and clean. You can tell was done right all the way from the street. If you're getting multiple bids for a roof replacement in the Madison area, make sure Sun Vault Roofing is one of them. Just don't let the price be the reason you go somewhere else, if they are not the lowest. The quality they provide is worth it.

The second time he told me it'd cost me for them to send out a full crew to assess what I already have to give me an estimate for adding onto the existing system if I didn't send them an engineer's drawing of what's already there. The only "work" involved with getting specs for an estimate would be 10 minutes worth of measuring by one person, maybe a few minutes more of discussion. The job I was looking for is a small one, and I know it would cost more per unit than a larger one, but paying for ONE person to come out and gather specs for an estimate is totally unreasonable. If you want solar, find someone else who really appreciates the business and is willing to provide decent service.

In October of 2024 I had the most excellent good fortune to work with Greenlink Energy Solutions as…read morepart of an ComEd Home Energy Efficiency project that included replacement of the furnace/a.c. and water heater, as well as top to bottom weatherization of my house. Even before the project started both Olivia and Jarron took the time to answer any questions and address any concerns I had regarding the equipment being installed and the overall scope of the project. Day 1, first up was a couple of electrical guys, quickly followed by Jarron and his HVAC team, Ben & Ryan. All on time and ready to get to it. Professional, pleasant and remarkably tolerant of my nonstop questions about the systems, the guys went to work and, other than a quick lunch break, worked nonstop, not particularly concerned about the clock but more about getting to a reasonable stopping place for the day. By the time they were finished, everything was operational, square and plumb, all pipes, valves, duct work and conduit looking very slick, orderly and professional. (5 stars just on the sheet metal work alone). Next up was the weatherization team with Nick leading the charge. Again, on time and ready to go. These guys, Zarek, Steven and Danial, came in with a plan and went right two it, peeling off to address varying issues and again, once on the ground it was go time for these guys. Remarkably, all willing and ready to jump in to even the less desirable parts of the project (like who really wants to go into a hot attic and crawl around in the corners? But they did it and with no hesitation or whining). Over all there were several things that impressed me about the Greenlink teams. There is the obvious stuff, like the punctuality and, remarkably, the through cleanup at the end of each day, and also the obvious work ethic, mutual respect amongst the team members and easy and informative communication with me. I think what was the most reassuring though, you could see the obvious pride the Greenlink people take in their work and, just as importantly, the obvious pride they take in working as part of the Greenlink team. That says a lot. I would not hesitate to recommend Greenlink Energy Solutions to anyone. I suspect my neighbors are already tired of hearing about how good they are.
