EFS Energy installed a 12 kW system on our farm building. The team was experienced and completed the work on schedule. Production has matched the estimate almost exactly. Great company for agricultural solar projects.
We chose EFS Energy for our residential installation after comparing several quotes. They offered competitive pricing with quality equipment. The Enphase monitoring system makes it easy to track our production daily.
Professional team with deep knowledge of the solar industry. Our commercial installation went smoothly, though the permitting process took a few extra weeks. The system is performing well and the ongoing support has been responsive.
