Soiling is the major cause of power loss of photovoltaics (PV) and concentrated solar power (CSP) in desert areas. Electrodynamic cleaning system (EDS) is an automatic and water‐free integrated cleaning system for mirrors or solar panels, which uses pulsed electric fields to remove dust off their surface. The first EDS field test over a long period on PV modules is reported here and shows a clear effect on soiling reduction in real conditions in Saudi Arabia. A total of 458 days of measurements is analyzed, and depending on the considered periods, performance losses due to soiling (soiling rate) can vary from −0.06%/day to −0.41%/day for a reference module, while the relative soiling rate reduction using an EDS can be up to 95.7% with an average of 32.1%. Cost calculations demonstrate an added value of the modules equipped with the EDS between 2.6 and 5.2 ¢/Wp compared with usual cleaning system, which is nearly between 10% and 20% of the module price.

太阳能电池板电动清洁系统的现场测试和电极优化

污染是沙漠地区光伏(PV)和聚光太阳能(CSP)功率损耗的主要原因。电动清洁系统(EDS)是用于镜子或太阳能电池板的自动无水集成清洁系统,该系统使用脉冲电场清除表面灰尘。本文报道了长期以来对光伏组件进行的首次EDS现场测试,结果表明,在实际条件下,沙特阿拉伯对减少污垢具有明显的影响。总共分析了458天的测量时间,根据所考虑的时间段,由于污染(性能下降)造成的性能损失对于参考模块而言可能从-0.06%/天到-0.41%/天不等,而相对污染率使用EDS最多可减少95.7%,平均减少32.1%。成本计算表明,配备EDS的模块的附加价值在2之间。
