Slate roof installation

I used EnergySage to help me find and evaluate an installer to work on my slate roof. They were very helpful in every step of the process, and I was glad to have them as a technical resource when deciding who to use, and how the installation would be done. I was very satisfied with the whole process, and as someone who works in the energy field, I am happy to recommend EnergySage to anyone considering adding solar panels.

Great Team

Overall, using SGE was a great experience. The sales contact, Dave Simmer, was extremely thorough and walked me through the whole process. I never felt too rushed, except for securing the loan from UMASSFive, but that's unrelated to SGE. Things happened quickly once National Grid approved everything, and SGE was ready to go within a week! The electrician/installer was phenomenal too. He worked with me on layout of equipment and even helped improve my electric panel to make sure everything was safe. Definitely recommend Pat for anything! As mentioned, communication about the loan was not as great, but that seemed to be independent of SGE. After everything was installed, I did lose a little bit of contact with them. There was an issue with the app (not the panels), and it took a bit to get corrected, but in the end it was fixed and I have had no issues since! They were always honest about pricing too and adjusted the quote when it turned out an extra panel wasn't needed.

An excellent option

We did not opt to go with SGE in the, but that had nothing to do with the excellent interactions we had with Dave Simmer. He shared a lot of insights and helped make our overall solar process better.

Benefits of the sun

I decided on SGE after reviewing comparisons on energysage. What I most liked about them was their follow up after providing an estimate for my home. They were very conservative with the production of the system as a few promised me incredible results. After being contacted by Doug Wahl, a tremendous asset to SGE, we set up a site visit. He did all the calculations on site and went back to the office to run them thru the system. Much to my delight we doubled the productivity that they originally estimated. With limited roof space I’m confident that a few other proposals would not have come close to what they stated as possible benefits from the sun. The installation process was also seamless. It was done professionally and not a typical one day in and out without the necessary inspections along the way which the larger companies tend to operate in that fashion. A great install team led by Craig made sure we taken care of most professionally. Doug was with us from start to finish which is a tremendous plus seeing that most salespeople disappear after closing the deal. In the end with the system up and running and near zero cost monthly to Eversource we were provided with a system designed with some of the most efficient panels and equipment on the market. Well worth every dollar spent. If you don’t feel they’re providing you with enough solar benefits compared to other bids on energysage do yourself the favor of setting up a site visit. They’re honest, reliable and do not disappoint!!

SGE proved to be a good choice for our solar project

We installed a 12kw system on our home back in Feb 2023. SGE/Steve was upfront about the general timeline and potential delays (from the utility company, inspector, etc.) that could pop up along the way. I would say expectations were set realistically, and they delivered within the timeframe they gave us. Steve was our rep and he is SUPER knowledgeable on all things Solar. Compared to the many other companies we vetted, he was responsive and went through things at a good pace. The installers they contracted with were fantastic (Craig & Skizz). They left the job site clean each day. Like most home projects, there were some hiccups, but unlike most home projects it was easy to work through them with SGE. I’ve recommended them many times over and would use them again if I had to go back and do it all over again.

My Super Solar System

We chose to go with SGE after reviewing all the options on EnergySage. They had the panels and inverters that I wanted and also spoke to me about other options and configurations. Dave was very knowledgeable and didn't push me in any specific direction as they are manufacturer agnostic and truly want to give the best option to the customer. Our system has been active for just over a month and we have produced just under a megawatt. The install process was very easy and looks super clean. I can only see my panels when I look out the second floor windows at the garage. I am excited to see what this system will do during peak solar exposure!
