Product Overview
The JA Solar bifacial panels generate power from both the front and rear surfaces, capturing reflected light from the ground to increase total yield. JA Solar uses PERC half-cut cell technology with multi-busbar construction for improved low-light performance and lower internal resistance, which suits the variable UK climate well.
The all-in-one inverter combines MPPT solar charging and pure sine wave AC output in a single compact unit. Pure sine wave output means the system runs all types of appliances and electronics cleanly, including motors, pumps and sensitive equipment. The battery is expandable: further modules can be connected in parallel as energy demand grows.
