Sri Saravanas Agencies In a standard solar system with a single central inverter, panels are wired together in a 'string.' If even one panel in the string is shaded or underperforming, it acts as a bottleneck, reducing the output of all the other panels in that string. Power optimizers prevent this issue. They are a form of Module Level Power Electronics (MLPEs) and work by performing Maximum Power Point Tracking (MPPT) for each panel individually.
