This ground mounted solar system has 440 W Longi Bifacial solar panels and is also battery ready. The bifacial panel will give you about 8% more production due to reflection off of the snow during the winter. This energy strategy encompassed the customer’s desire to add a battery next year. Thus, we installed a SolArk 12kW inverter and have it ready to take a battery. Along with it is a 15.0 kW Fronius grid tied inverter. This was installed about 150′ from the customer’s home.
