Partial shading is widely considered to be a limiting factor in the performance of photovoltaic (PV) systems applied in urban environments. Modern system architectures combined with per module deployment of power electronics have been used to improve performance especially at heterogeneous irradiance conditions. In this work another approach is used to combine modern system architecture with alternate module designs. The granularity of cell groups in PV modules is investigated together with the so-called Tessera concept, in which single cells are cut in 16 parts. Typical meteorological year yield calculations show that these alternate module designs in combination with modern system architectures can retrieve up to half the shading losses compared to standard modules and string inverters under identical shading conditions.

太阳能电池组粒度和现代系统架构对晶体硅组件和系统局部遮光响应的影响

部分遮阳被广泛认为是影响城市环境中光伏 (PV) 系统性能的一个限制因素。现代系统架构与功率电子器件的每个模块部署相结合，已被用于提高性能，尤其是在不同辐照度条件下。在这项工作中，另一种方法用于将现代系统架构与替代模块设计相结合。光伏组件中电池组的粒度与所谓的 Tessera 概念一起研究，其中单个电池被切成 16 个部分。典型的气象年产量计算表明，在相同的遮光条件下，与标准模块和组串逆变器相比，这些替代模块设计与现代系统架构相结合，最多可恢复一半的遮光损失。
