A reconfigurable solar photovoltaic arrayunder shadow conditions

Do photovoltaic array reconfiguration methods reduce the impact of partial shading?

In order to solve this problem, the photovoltaic array reconfiguration methods are developed to mitigate the impact of partial shading and increase output power. This work aims to undertake a comprehensive review on state-of-the-art photovoltaic array reconfiguration methods through a thoroughly investigation of 125 recently published papers.

Can photovoltaic arrays be reconfigured?

The authors’ own research on PV array reconfiguration are provided. Several constructive recommendations are given for future development. An intractable but common problem in photovoltaic systems is that the power generated by photovoltaic will reduce seriously due to partial shading.

Why is partial shading a problem in photovoltaic arrays?

5. Conclusions Partial shading is one of the most important problems that make it difficult to extract maximum power from photovoltaic (PV) arrays. This issue has raised many challenges so far and various methods have been proposed to solve this problem.

What is adaptive photovoltaic array reconfiguration based on real cloud patterns?

Adaptive photovoltaic array reconfiguration based on real cloud patterns to mitigate effects of non-uniform spatial irradiance profiles Sol Energy, 155 ( 2017), pp. 506 - 516, 10.1016/j.solener.2017.06.052 Maximum power from PV arrays using a fixed configuration under different shading conditions

What is the purpose of PV array reconfiguration?

The immediate purpose of PV array reconfiguration is to evenly distribute the uneven shadows across the whole array , . The premise of reconfiguration is to obtain the key parameters and data of PV array.

Can gravity search algorithm-based photovoltaic array reconfiguration reduce partial shading losses?
