Celestial Solar Innovations, LLC review

Positive reviews:

“Celestial Solar Innovations installed a 57 panel system on our home. After speaking with 5 other vendors, we went with CSI because Jim provided a competitive price while respecting our focuses of maximizing the use of space and good aesthetics. Jim answered all of our questions thoroughly with low sales pressure. The installation crew members were polite and always on time. Jim responded to our questions promptly throughout the process and helped us get all our paperwork filed. The system was turned on relatively soon after the installation was complete. I strongly recommend working with CSI on any home solar system.” – mskluev ⭐⭐⭐⭐⭐ May 26, 2017

“Jim Reilly and Celestial Solar Innovations installed a 60 panel system on our home. From the initial discussion through the final hook-up and beyond, the service and professionalism were at the highest level. Calls or e-mails were promptly answered, alternative options presented, and sound advise built confidence. The quality of the work was outstanding, down to the level of aesthetic placement of wiring. All work was performed as scheduled without delays. Following the installation Jim then supervised the filing of all necessary applications. Since the system went live the energy production has been as anticipated. I can recommend this firm without hesitation.” – rbrookla ⭐⭐⭐⭐⭐ December 11, 2016

“We contacted Celestial Solar from a referral in June/July timeframe. Jim Reilly, the owner of the company, worked with us on the design and pricing during our due diligence stage. Jim was very professional and courteous. He told us that they were backed up and it would be around Oct./Nov for installation and activation. He set our expectations and his team delivered it slightly ahead of schedule. The team did a excellent job of installation, working with the county inspector and Pepco on approval and activation. I was so impressed with Jim that I even referred his company to a close friend/relative even before the actual installation.” – Veena and Ramesh ⭐⭐⭐⭐⭐ January 13, 2026

“I’m very happy with the installation and the overall process. They were very communicative and kept me in the loop at each step of the process. The actual install only took a day and we were up and running a couple weeks after that once everything was approved. Very pleased with everything.” – Nick Deimler ⭐⭐⭐⭐⭐ November 19, 2025

“Jim Reilly and the Celestial Solar Innovations team have been nothing but amazing in our solar journey from start to finish. We interviewed 4 different companies looking for the best fit for our goals and after the meeting with Jim it was clear that Celestial had earned our business. It didn’t hurt that Celestial had been recommended personally by two engineers at my firm. Jim was communicative and informative in a way that makes you feel respected as a customer. At no point during the project did I feel like we were left in the dark. Together with his team they designed our system to perfectly fit on our roof and at the lowest cost per kWh out of the 4. However, the customer experience, craftsmanship, and materials were a testament to the quality they bring to the table. Jim is an upstanding guy and we will be shouting Celestial’s name from our new rooftop.” – Jesse C. ⭐⭐⭐⭐⭐ December 5, 2025

“Overall great experience. I was referred from a neighbor, who is also very happy. They were competitive on price, were upfront/transparent with numbers, communication was always solid, even after installation. There were a couple of small issues, but nothing to complain about. They forgot to take final photos before they left, so I snapped a couple of shots for them. If that’s the worst of it, I’d use them again. So far so good on the system. Jim (owner) is a good guy and his wife put together a package of things to file for all of the rebates that made it easy for me.” – Kevin W. ⭐⭐⭐⭐⭐ October 15, 2024

“We had Celestial Solar complete the installation of our solar unit at the end of May 2025. The whole team did an amazing job from start to finish – design, county approvals, utility company, SRECS, installation, monitoring system, and even helped me with a state grant program. The owner was always available and the whole team was super helpful and communicative. We had ZERO issues – so smooth. Our system was designed for 100% offset and we have out produced usage every day since install. The panels look great. We couldn’t be happier with our choice. I received over ten different estimates from the leading solar companies and not only was Celestial competitive with the most competitive prices, but offered higher quality materials and completes all the work in house. Highly recommend.” – John M ⭐⭐⭐⭐⭐ July 7, 2025

“Celestial Solar did a great job with the installation. The entire process was straightforward – Jim made everything clear and there were no surprises. No high-pressure sales gimmicks like from some other companies I dealt with, and the end system is high quality and the price was quite reasonable. Highly recommended!” – John V ⭐⭐⭐⭐⭐ June 23, 2024

Positive reviews:

“I am not surprised they have so many good reviews. Celestial Solar is a very honest, straightforward company that is a breeze to work with. They installed solar panels for us about 8 years ago. Jim came up with a really efficient approach to locating the panels on our roof and the system has been flawless since then. We wanted to add batteries for the past couple of years and I could not find any installers willing to work with us (Celestial Solar just started installing batteries). When I found out Jim had just expanded his business to include batteries, I knew I could complete this project. It took a few months because of the backlog of work but I was happy to wait. They did the installation in 3 days including the installation of a subpanel. The installers were very neat and helped me make sure I had all the circuits I needed. The installers answered my questions and configured the system correctly. Jim was very communicative and it was a pleasure working with him. The battery system meets all my expectations.” – Dennis Timlin ⭐⭐⭐⭐⭐ January 2026
