Optimal PV array configurations for partial shading conditions
Indonesian Journal of Electrical Engineering and Computer Science, 2023 Increasing the effectiveness of photovoltaic (PV) power generation systems is a major barrier to their widespread use. Partial shading conditions (PSCs), which are caused by nearby objects like trees, buildings, and clouds, reduce the energy produced by PV systems and may be mitigated by the reconfiguration of PV arrays.

A Review of MPPT Algorithms for Partial Shading Conditions
Acta Physica Polonica A, 2017 Maximum power point tracker in a photovoltaic system allows to maximize the energy drawn from the connected photovoltaic modules. In the partial shade conditions there can be more than one maximum point in photovoltaic output power curve. The solution for this situation is a maximum power point tracker algorithm, which finds the global maximum.
