 Trustindex verifies that the original source of the review is Google. The OneGrid team was wonderful! They were all kind, professional, and super responsive to our questions. They gave us clear expectations and explanations throughout and left our house and yard in a neat state after they were done. We’re really excited about our new panels and appreciated the easy installation process!

 Trustindex verifies that the original source of the review is Google. The materials were delivered the night before. The crew showed up at the right time and started working right away. Seems like a very experienced team and hardly any conversations needed. They installed our panels on the main roof and on the side roof. Very efficient and they finished before time. Cables lined up as agreed. Battery in the middle of the wall and lined up as agreed. Cabling and electrical work was excellent as well. In our previous house we had solar as well; this crew from One-grid was significant better. Highly recommend them and a great experience.

 Trustindex verifies that the original source of the review is Google. Dexter sold me my panels before he started this venture and has been more responsive than anyone I do business with. Even after leaving the original installer of my system, he actually communicated better than they did when I had an electrical issue. Despite the fact he stood to gain nothing from me since the sale was completed years ago. Service means something, especially in the automated world we now live in.  If anyone asks me about solar, I recommend him every time.
