Trusted Solar Installers Serving the Northeast

Everything was done professionally. From the initial consultation to the installation to the implementation. Top notch.

Awesome crew. They did a great job. Dan, Dave Darell, Rob & Jimmy all worked so hard and are all perfectionist. Tom Labbe and Rob Zappone are great business leaders and always do what’s best for their customers

Very happy with the installation the crew was very professional and the most important thing when they were done they clean up after themselves next step looking forward paying less electricity. Thank you Sissi

ISP Solar is THE place to add solar to your home. Nick guided us from start to finish. Oh, our last electric bill from Eversource. Zero dollars. Call Nick and get Solar !!!

The installers were very fast and efficient!

Chris and his team were a delight to work with. They guided me through the whole process and were entirely professional. I have never seen someone as responsive and attentive as Chris. All you need is a message and he replies right back. He never hesitates to clear up any question you have. If only every company has a person like Chris! Five stars!

Best of the best! Customer service was great kept me informed the whole time! Everything was super convenient

We just went solar with ISP (Ion Solar Pros). We began talking in February. We always wanted to get solar panels on our home but it never seemed to work out after previous discussions with various providers over the last two decades. Every discussion over the years with various companies ended up with it being “too” something. Too expensive, too many trees, roof too old, electric bill too low, etc. It was not a failure on the providers part but there were always obstacles. Working with Eli at ISP opened up options which proved positive. We signed a contract and everything moved forward without a hitch. ISP representatives kept me informed through all the steps. Appointments were made and appointments were kept. Layouts were presented and installation was on time and fast! Components were state of the art and the highest quality. No headaches at all and the system should be going live next week! I would recommend Ion Solar Pros without hesitation.

Installation was smooth and painless. The “Red Team” was polite and we’re sure to keep my home clean while they worked. Thanks ISP RED!

We had a outstanding working experience with Geo from isp (Geo) was professional extremely patient he took his time through the process explaining everything clearly even showed up at the the installation I also want to shout out (John) (Jaylyn) and both of the electricians Astro and Dara the whole crew were professional and extremely knowledgeable throughout the installation process and on time if your thinking about going Solar I highly recommend reaching out to Geo at isp he delivers excellent service.

Very professional and knowledgeable. Ion Solar Pros make the process of getting solar panels installed incredibly easy.

I recently hired isp to install solar on my house from day 1 thomas labbe was on site with all of his knowledge on the process and timeline of which he was very accurate then comes install. John Duffy of red team not only was he very adept of my situation he told me everything I was going to encounter going forward. I cannot say enough of the entire crew at isp. I would recommend isp without any hesitation

They were very nice, did a great job cleaning up & had the job finished earlier than promised.

Great expirience, everyone through the process was awesome. Very reasonable prices and plans that will be saving me money from Day 1. Mike Z made everything very simple, presented plans, options, answered all my questions, worked with my suggestions. Very responsive to any concerns that arose. The install team: liam, Cedric, Jeremy, and dave. Top notch and professional. Work for the company, not some subcontractors that dont care. Inspections, permits, even an issue with Eversource, all handled by ISP. Would definitely recommend.

Fast and efficient. Answered my questions quickly. Gave me detailed instructions on when they would be ready to work

The purple team did an excellent job showed up before their scheduled appointment did everything in a timely manner everything was neat and organized very friendly staff enjoyed having them at my house

Armando and iSP Solar did an amazing job with our solar project. We could not be happier! From start to finish communication was outstanding. The installation was seamless and they addressed any and all concerns we had throughout the process. I would recommend them to anyone looking to go solar!

ISP installed our solar system on time as promised. The panels look great and we were happy with the extra benefit of Solar Insure. Would recommend working with them on solar projects.

The Red Crew (Jon, Dan, Astro, Brendan & Mark) from ISP Solar is amazing, the crew was very professional and a bunch of nice guys. They were very courteous, they made sure everything was clean, especially when they had to enter the house. Awesome crew!

The installers were professional, neat, organized, courteous, and they kept me in the loop every step of the way.

Amazing experience. The Ion Solar team did an outstanding job. Effortless and Smooth. I would highly recommend if you are considering solar. They have incredible patience and on top of every detail. Big thank you!!
