Highly Efficient DC–DC Boost Converter Achieved With Improved MPPT‐Based Raspberry Pi for Enhancing Photovoltaic System Generation

International Journal of Energy Research, Volume 2024, Issue 1, 2024.
The operation of photovoltaic (PV) panels in partial shade (PS) conditions (PSCs) lowers the quantity of energy generated due to the hot spots that increase the power loss. In this scenario, a maximum power point tracker (MPPT) is necessary to monitor the power–voltage curve, which features multiple local peaks in addition to one global peak (GP).
