We have installed hundreds of residential projects throughout Rhode Island and SE Massachusetts ranging in size from a small 6 panel array (1.86 kW DC kW) to a 60-panel barn top (20 kW DC) installation.

We have also designed and installed many small-scale commercial projects for area farmers and business owners.

SunWatt installed a system on my home and I couldn't be happier. They were great to work with from beginning to end. We have had our system for one year now. It has been performing well. The team has continued to be supportive. In the end it comes down to would I recommend them to a friend or family member and SunWatt gets a yes!

After extensive research and many consultations we ultimately decided to go with Sunwatt solar. Dana, Aaron, Lars, Joseph, Steve and the rest of the team were outstanding. Throughout the whole process from sales to installation everything went incredibly smooth. They stuck to the timeline and everything was completed in a timely manner. I cannot recommend this company and team enough!

All the folks at Sunwatt from sales to installation to connection to the grid were so friendly and professional. Easy to get ahold of, honest, and I'm super happy with the panel installation. I never felt like any of my questions were dumb, and now we're making our own power! I've recommended Sunwatt to friends and neighbors and so random stranger, I recommend Sunwatt to you. I've got no regrets.
Working with Sunwatt was amazing! After one too many doorbell rings by other solar companies, we approached Sunwatt to quote out a system for us. They were extremely responsive, proactive, and on top of every detail. Not only was the pricing extremely competitive, they took the time to speak in depth with my husband and I about the nuances of our specific set-up. They handled all the components of the solar project, keeping my husband and I up to speed on everything, but allowing us to get on with our daily life. I’d work with them again in a heartbeat!
We had a great experience using Sunwatt Solar. The team in the office and the installers were very professional and pleasant to work with. They help you with all of the paperwork and every step along the way with excellent communication throughout the entire process from start to finish. We would highly recommend them to anyone.

Dana and the Sunwatt team were great to work with. They answered all of my many, many questions fully. The install went smoothly and was completed in a timely manner. I would recommend them to anyone who is looking to add solar to their home.

As PhD scientist and entrepreneur, I was fortunate that I selected SunWatt after a rigorous process of analyzing >12 potential installers by inspection of the formal contract offerings and based on reputation and value (Paid in full, no financing). I was advised by independent experts that Sunwatt and 2 other companies were trusted and were regularly applying for max $5000 RI incentive grants to contribute towards installation. The total cost was highly competitive and cost matched any other offer, with or without RI grant, which they successfully arranged on my behalf. I would not hesitate to recommend SunWatt and hope that they can expand in capacity vs other disreputable installers. I assessed that 8/12 other companies were fundamentally unacceptable: not applying for RI grant ($5k), misrepresenting contract actually being provided, providing grossly inflated projects or predatory loan/financing. I had one friend who paid the same price for a system with 50% the capacity and misleading/predatory loan terms that have significantly harmed her. Fortunately, such predatory companies tend not to escape the attention of the RI DOJ...

We chose Sunwatt for our solar installation for two reason. Frist their quote was very competitive compare to the other quotes we received. Second when working with them and asking question about options and the system they provided very technical answers compared to some of the other companies we contacted who provided more of a "sales pitch" answer. They were very honest about some of the con's of the options which helped us set realistic expectations of our system. As a result we have been very happy with our solar system as it meets our needs and there were no surprises. Additionally, the work they did was excellent. We didn't have any issues with any part of the install. I would like to thank both Dana and Aaron who were very helpful through the whole process.
