Determination of the optimal configuration for a photovoltaic array depending on the shading condition

Impact of Partial Shading on the P-V Characteristics and the Maximum Power of a Photovoltaic String

“…S. Silvestre et al discovered that a partially shaded photovoltaic system is not necessarily susceptible to the shading heaviness. They discovered that the maximum power of a partially shaded photovoltaic system decreases as the shading heaviness increases, as presented by the researchers in [26][27][28][29][30][31][32][33][34][35][36][37][38]. However, when the shading heaviness reaches a certain critical point, the maximum power remains unchanged even if the shading heaviness is getting heavier and heavier from that critical point, as illustrated in Figure 4b.…”

“…This finding is inspiring because a partially shaded photovoltaic system is commonly believed to always be susceptible to the shading heaviness. Apparently, a photovoltaic system is highly susceptible to partial shading [26][27][28][29][30][31][32][33][34][35][36][37][38][39]. During partial shading, the maximum power of a photovoltaic system can drop drastically, which significantly reduces the energy yield of the photovoltaic system.…”

“…However, the susceptibility of partial shading to a photovoltaic system is not constant. The susceptibility of partial shading to a photovoltaic system can be varied due to the partial shading pattern and the connection employed to connect the photovoltaic modules in the photovoltaic system [26][27][28][29][32][33][34][35][36][37][38].…”

“…It is obvious that lots of research has been conducted on the impact of partial shading on the photovoltaic system throughout the years [26][27][28][29][30][31][32][33][34][35][36][37][38]. However, none of it has precisely presented the finding proposed in [39], which stated that the maximum power of a partially shaded photovoltaic system can become insusceptible to shading heaviness when the shading heaviness reaches a certain critical point.…”

Evaluation of the impact of partial shading and its transmittance on the performance of crystalline silicon photovoltaic modules

“…It will be important to investigate the type of shadow (transmittance) and the relative surface area of the shadow (Reinoso et al, 2013). The influence of partial shading on PV modules has been studied by several authors (Wang and Hsu, 2011;Gluchy et al, 2014;Tian et al, 2013). Some have focused on the angle of optimal system configuration under partial shading (Topic et al, 2017).…”
