Which PV array configuration performs better under shading patterns?

A detailed comparison is made on various PV array configurations under uneven and even row and column shadings. 14 The authors concluded that out of various configurations, TCT array configuration is performing better under considered shading patterns.

How a PV module is connected?

A connection of the number of PV cells in series can obtain the PV module and the connection of number of PV modules in series or in parallel to get required load voltage and currents referred to as PV array which is shown in Figure 1B. The relation between the PV module's output current and voltage is specified by Equation (2).

What are the effects of shading in a PV array?

It is also observed that, the increment of shaded PV modules in a PV array causes, multiple peaks in P-V curve, lower output power and higher mismatching power loss. It is noticed that, TT PV array configuration provides the highest GPP under center, right side, frame and diagonal shading patterns over SP, BL and HC PV configurations.

What are the performance parameters of PV array configurations?

The FF and efficiency of all configurations are nearly 73.99% and 14.1541% respectively. For all the configurations, the mismatch loss is almost zero and the voltages and currents generated at GPPs are almost same. TABLE 1. Variation in performance parameters of PV array configurations b. Under corner shading pattern c. Under center shading pattern

How does shading affect GPP in a PV array?

From the simulation study, it is observed that the generated GPP from the PV array depends on the kind of shading pattern and the shading level. It is also observed that, the increment of shaded PV modules in a PV array causes, multiple peaks in P-V curve, lower output power and higher mismatching power loss.

Why do PV modules have partial shading?

Partial shading is due to the shadows of passing clouds, chimneys, trees, bird droppings, various tall building structures etc. At the PSCs, the local hotspots are formed in the partially shaded PV modules due to increase in temperature of the shaded module during its operation in reverse bias condition.
