Predetermined static configurations of a partially shaded photovoltaic module
Abstract: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.
