    We chose Ace through Energy Sage. They were well rated and came in with a low price. The delivery and installation went without incident. Communication of what was going to happen was good. The design met our usage needs, we have generated a few percent more electricity that we used in the summer. Post installation communication has been good in answering lingering questions about the MA SMART program.

    We are satisfied customers and hence gave the 5 star rating.

  • "Truly an ACE"

    Reviewed Oct 03, 2019

    What an outstanding job Ace did in installing and co-ordinating the entire system. After 4 months I can truly say that we are very pleased with the performance and pay back thus far. We are also very pleased that we can help in reducing our carbon footprint and global warming. We hope that state governments will help develop individual rooftop solar vs clearing fields! An certainly company like Ace can offer a smooth implementation.

  • "Excellent performance at 1yr+"

    Reviewed Oct 03, 2019

    I selected ACE Solar after speaking to them and they answered all my questions. Based on my selection criteria, they had the perfect solution. One aspect that I wasn't sure of was production estimate. Their estimate was higher than all the competitors who bid on the project. Now after a year, I can say that they were on the mark with their production estimate. Since I added a few extra panels, I made a request to upgrade the solaredge inverter to avoid excessive clipping and they made that change promptly.

    I can't speak enough about the professionalism of the installation crew. They are prompt, courteous and even took the antenna and replaced a few items on the roof at my request. Thank you so much ACE Solar.

    We had a great experience with ACE Solar in our solar installation on Nantucket. There were many logistical hurdles and a lengthy process with the Historic District Commission, but they handled it all with professionalism and competence. Price was fair and we’re delighted with the system’s appearance and performance. Strongly recommend ACE. They were a pleasure to work with.

  • "Shrewsbury, MA Install"

    Reviewed Apr 18, 2018

    It's been 3 months since my solar array installation and I couldn't be happier. My utility bill is almost nothing except for the fees for net meter service fee and it's not even summer. I signed the agreement in late Oct'17 and my panels were installed before Christmas. The project manager, installers and sales person were very honest and helpful through the process. I highly recommend ACE solar.

    "Could Not Ask for More"

    Reviewed Apr 08, 2018

    Without a doubt this was the easiest home improvement I have ever experienced. Josh Mailloux (Sales&Support) and Shirley Mapes (Project Manager) both get 5 Stars. They were available and straight forward with answers to any question posed to them AND they responded in a timely manner!

    The installers were all great, the electricians were informative and listened to my needs prior to moving forward. Any problem was addressed more then adequately.

    The system system was up and running within reason given this winter weather of 2018. I also began seeing savings within only two weeks of turning the system on with a 48% drop in use from the previous year. More than I expected!

    Highly recommended.

    "Happy customer in Lincoln, MA"

    Reviewed Mar 24, 2018

    Josh and the ACE Solar team did a tremendous job helping us navigate the processes for our solar installation. The communication was always responsive. All of our emails were answered in less than a day. The site visit and installation on time and conducted professionally.

    When we decided to add more panels to increase production, Josh's team worked quickly to redesign the layout and help us with the change order form. They also deal directly with the utility and SREC companies to get us set up. All documents were signed electronically.

    In the end, Josh gave us a folder with all the tax forms, receipts, design documents, and warranty information. We are extremely happy with our decision to go solar. ACE Solar made it as painless as I could hope for.

    Josh and the team for ACE Solar did a great job. Josh really knew his product, and was able to answer all our solar questions. They provided great follow through. I would highly recommend.

    "Good communication and service"

    Reviewed Jun 28, 2017

    I had a very good experience. Josh and Shirley responded quickly to my questions and helped me navigate all the paperwork I had to complete. When my local Historic District Commission required a hearing for my permit—it turns out that I am the first homeowner in any of my city's many historic districts to go solar—Josh came all the way down to attend the meeting and kept me updated on the progress. There were some delays in completing the job due to that permitting process, but Josh kept me in the loop and helped ensure that the rescheduled installation date would be as convenient as possible with my work schedule.

    My system has been up-and-running about a month, so it's early to comment on the long-term durability of the system, but I am very pleased so far!

    There are a lot of options for solar. More than I even knew. I met with a few and found several to be pushy, gimmicky and overpriced. Josh Mailloux and his team were professional, informative, patient and thorough. The communication was great, the install was great and the result was great!!

  • "Cant be beat!!"

    Reviewed Mar 01, 2017

    Going solar with ACE was fast, easy, and professional. Their pricing was very competitive and actually lower than some of those big name companies. They took care of all the paperwork for the project. I purchased my panels, and they even set me up with a local bank that could get me the best rate. Communication was fast and easy as they respond to email, calls, and even texts. Any question I had they answered quickly. Their install team came out and installed all 27 panels on 3 different roofs in a single day. They worked quickly to get the inspectors out and my meter swapped. I had my panels up and running within two weeks of install. That was 4-6 weeks faster than quotes I had received from other companies. They also have a great website for monitoring your production as well as a cell phone app so u can check it on the go!! Great company and great team with Josh and Chris leading the way. Thanks again guys! Great work!

  • "Incredible Experience"

    Reviewed Feb 28, 2017

    Choosing ACE Solar was an incredible experience. From start to finish, they nailed it!

    They completed a complicated 34 panel installation within two days, and did everything "just right".

    ACE Solar came ready to the job site - they already had all the permits, approvals and plans.

    The team was ready to face the installation challenges and was able to bring the wires from the roof to the attic, and through the flue to the basement. Then, concealed within the ceiling of the finished basement, the power was sent back to the main breaker panel.

    Once the installation was completed, they ensured that my system would be registered with an aggregator so that I could get the SREC credits.

  • "would strongly recommend"

    Reviewed Feb 03, 2017

    We were very pleased with our experience with Ace Solar. They responded to our questions right away, but were not high pressure. They installed our system very promptly, finishing earlier than they had predicted. (We were hoping to meet the January 8th deadline for a better compensation rate for the SREC program, and they got it installed before the deadline). Our roof was a little tricky, due to a dormer, but the panels were put up nicely around the dormer. We have recommended ACE Solar to our friends.

Done in 1 day, all cleaned up. Inspected 2 days later, waiting for the State ok and National Grid. Very smooth and fast project, the only hitch was a slow Weymouth saving bank for the Ma. solar loan.

    I selected American Capital Energy (ACE) to install a solar system on my home. Eric McLean and Bob Kiley were very professional and responsive and answered all my questions in a timely manner. Eric and Bob were available through the whole process. Their installation team did a great job, all the permits were pulled and there were no issues with the install during the town inspections and everything passed first time out. If you want a hassle free installation and a company that will stand by their work, go no further than Eric and Bob from ACE
