Distributed MPPT Configuration for Improving Solar Energy Production

Photovoltaic (PV) energy is becoming a more common way to produce clean, renewable energy. The PV modules with lengthy strings will be affected for the shading effects, resulting in a huge decrease in the final output power. To counter this, distributed maximum power point monitoring has been suggested, in which individual DC-DC converters are connected to a central DC-DC converter in which each PV module to get the most power out of it. To achieve the opti-mum power output, Distributed MPPT (DMPPT) is used and it compensates for shading effects and module mismatching issues.
