"I originally found out about this company, SONERGY USA, as I had to have the inverters replaced for an existing solar panel setup I had. The folks I interacted with were amazing and extremely professional. They were able to take care of the repairs right away, but more importantly they fixed some items the original solar panel installer did not do properly. I was so impressed by the work SONERGY USA did with the repairs that I eventually moved forward to get additional panels installed and even a battery installed. Again SONERGY USA did not disappoint. Everything was professional and done properly. Most of all the communication with the team was amazing where I did not have to babysit them or waste time off from work in order to get the work completed. SONERGY USA stuck to the timeline as well. which I greatly appreciated."

"We are very pleased with the solar panels, battery and energy system installed by Lumina Solar. Their sales pitch was informative, more than pressure sales. We discussed options available for solar and we selected Lumina Solar after considering two other companies. All of their team members were professional and thorough. We even experienced a small problem with our installation and their CEO stepped in to make things right, without hesitation. We highly recommend Lumina Solar to anyone who is actively looking to install solar panels for their home."
