Solar "A" Team!

Jim and Celestial Solar team were great to work with. They were responsive, professional, knowledgeable, and did great work. I wouldn't hesitate to recommend them. Their quote was accurate and no-nonsense; Jim worked out a couple different array options with us to look at different panel counts and mounting arrangements. He was patient in reviewing the options with us and working thru some permitting issues with the county. We have been live for a month now and love not paying for electricity anymore!

Great Solar Experience

My husband and I are very pleased with our solar panels, and even more so with our experience with Jim and Celestial Solar. After almost committing to Solar City, and hours of basically a sales speech, my neighbor told me about Jim and Celestial Solar and her great experience. Jim arranged a Zoom meeting with us after first getting an estimate of the project scope and cost. The installation was great. Jim really knows his business, and is quick to respond to questions and concerns. We have seen our electric bills basically vanish since our installation in July. Although of course, those are the sunnier, warmer months. We highly recommend Jim and his company.

I couldn't be happier with my decision to work with Celestial! I spent way too much time trying to familiarize myself with solar hardware so I could confirm which of the many quotes I got was the best value when I could have just trusted the reviews. Celestial has been extremely diligent in their work and helpful with all my questions. They made the process as quick and easy as I could have imagined while providing incredible value with their industry-leading hardware. Now that I can see the impact I'm making on my electric bill, I can say with certainty that they were the right choice!

Exceeded my expectations!

Amazing work by Jim & Celestial Solar...it only took two days to complete the project, got approval by the county in a couple of days, then we went live much faster than expected. Jim was very easy to work with and answered all of our questions thoroughly. Would recommend 100%!

Smooth installation, great service

Celestial Solar did a great job with my solar installation. Jim was helpful in my free consultation, answering all my questions and providing a couple great options for my array configuration. The installation team was fast and friendly. They knew I was scared that my dogs might get loose when they were coming and going, and they took great care to knock when entering and having me hold the dogs when leaving. The array has been running for a couple months now and is already making a huge difference in my electric bill. The team at Celestial has been so great with their follow-ups, between getting me set up to monitor production to setting me up to trade solar credits and everything else I've needed. They're knowledgeable, friendly, and professional - you can't go wrong with Celestial.

Choose Celestial - you will not regret it

When I started researching which solar company to use, I had 4 companies provide bids. 3 of those companies were big chains that were quoting me for systems significantly too big, didn't understand local ordinances, and promising me things they could just not deliver. Celestial Solar, however, came in and explained everything to me very clearly right from the start. They were not the least expensive, but they provided me the best financing options, sent me ALL of the details on their products before our first meeting, provided a dozen customer testimonials (which none of the others did), and went above and beyond communicating to me throughout the entire process. It was a no -brainer when it came for who to choose and I 100% recommend them for your solar install.

Easy Decision - Highly recommend

Celestial Solar did an excellent job installing solar panels on our house in August 2023. We did a lot of research into various companies and Celestial Solar was an easy selection. Jim Reilly was great to work with. He explained everything (cost, process, benefits), answered all of our questions quickly and thoroughly, which made the decision very easy. Absolutely recommend them.

Outstanding Company

We had Celestial Solar install panels on our house in August, 2023. After checking other companies, it looked like Celestial would be easy to work with, and that turned out to be very true. Jim was always clear about what would work best for our house. He presented detailed and articulate plans for the project. He was responsive and helpful. The work was done quickly and professionally. We were kept informed every step of the process. Our solar panels are producing more electricity than we use each month, just as Jim predicted. This was one of the best companies I have worked with in 50 years.

Great Company

Jim and Celestial Solar were responsive, professional, and did great work. I wouldn't hesitate to recommend them to anyone. Their quote was accurate and no-nonsense. Timelines were accurate. Months after the install, they resolved a warranty repair on my solar combiner and were just as responsive. One of the best companies I've ever hired to do work on my home.
