Solar Panel Shading: Analysis and Solutions

The maximum or global power point is then found at the string level to optimise the output. However, with a SolarEdge installation the panel optimiser would maximise the performance of the shaded panel, by finding the maximum power point of the panel rather than the string. An alternative to DC-DC panel optimisation is Enphase micro-inverters.
