Celestial Solar Innovations installed a large solar array at my Chevy Chase MD home in 2016. I was very pleased with their attention to detail and the high quality of the installation. Jim Reilly provided excellent and professional advice from the design and selection of components through the completed installation and operation of the system. Mr. Reilly is an expert in solar installations. He was instrumental in identifying the most appropriate panels for my home. At his suggestion I used black on black LG panels which were a perfect solution for my home. I highly recommend Celestial Solar Innovations and Jim Reilly.
