Predetermined static configurations of a partially shaded photovoltaic module

Partial shading causes power loss in a photovoltaic module by inducing a power mismatch within the module. This power loss can be significant in building‐applied and building‐integrated photovoltaic installations. Given the often repetitive nature of shade profiles in such applications, we propose to employ non‐reconfigurable or static configurations. We use our simulation tool to precompute static configurations, apply shading scenarios, such as a chimney or tree shade, and make a comparison between the energy yields of different static configurations, which includes that of a conventional module. We then identify the configuration characteristics that consistently yield a higher energy. Copyright © 2016 John Wiley & Sons, Ltd. We propose a method to compute the energy yield of a photovoltaic module subject to partial shading. By applying constraints, we generate series‐parallel cell configurations that are practically feasible, and identify the configuration characteristics that consistently yield a higher energy. We show that by proper design of the PV module's configuration the energy yield can be significantly improved over that of the conventional configuration.
