"Aduu Solar Energy was Easy and efficient company. Aduu Solar Energy was simple, informative and straightforward. Each person I dealt with knew status and what the next step was. Everyone was courteous and listened to and answered my many questions. Installers were great people and neat too. System is working very well, generating more than I thought. I'd highly recommend Aduu Solar Energy for solar panel installation."

"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."

"Quick turnaround, professional service, great rate."

"Fantastic. Very thorough, nice, communicated the process very well and did great work."

"I emailed Day and Night Plumber after my old water heater started shooting water out the front panel and within 10 minutes I got a phone call from them with an appointment for an estimate with Marin. The quote was very reasonable and after I supplied the Hybrid Water Heater, Marin was able to come install it on Sunday. He was extremely knowledgeable, efficient, and hard working. He finished everything, cleaned up the area, hauled away my old water heater, and showed me how everything worked. He even gave me a military discount and 12 month warranty on labor. If you need a plumber for anything, give Day and Night Plumber a call, they will give you top notch service for a reasonable price."
