HIGH YIELDS DESPITE SHADE
People who have installed a PV system on the roof naturally want to collect as much sunshine as possible. However, what if a tree, chimney or even a neighboring house casts its shadow on the modules?
It’s not a problem because SMA has the right solution, no matter the size of the shadow on the PV system.
We will present our solutions to you and explain when which option makes sense.
1. OptiTrac Global Peak: shade management is part of the SMA inverter
The inverter’s MPP-tracker has a decisive influence on the energy yield of a partially shaded system. It continuously operates the PV modules assigned to it at their optimum power, also known as the maximum power point (MPP).
We have optimized the MPP tracking with the specially developed shade management function OptiTrac Global Peak for manageable PV system shading of 15 to 20 percent. It has been integrated into all SMA string inverters. In shading situations, OptiTrac Global Peak always automatically recognizes the global maximum performance of the affected module and can therefore almost completely use the available energy of a partially shaded string.
