Abstract

Abstract The article describes an experimental investigation of the impact of soiling on the photovoltaic modules in northeastern, Iraq. Over five months, the voltage, current power and energy curves of two identical modules with varying cleaning strategies (one was naturally dusty while the other was cleaned regularly) were measured. The impact of soiling on the daily energy produced as well as rain accumulation and particulate matter concentrations are discussed. The results indicated that no losses occurred during wet seasons, but a considerable decline in performance was found during dry periods owing to soiling. Additionally, it was discovered that soiling has a bigger effect on the maximum power than the short-circuit current. After two dry summer months, the greatest power loss of up to 22% was seen. The daily energy loss due to soiling was determined to be 16% on average. Furthermore, there are four polynomial models that have been drowned in prediction photovoltaic module (voltage, current, power, and energy) degradation due to the accumulation of dust.

污染对光伏组件发电影响的实验研究

摘要本文介绍了在伊拉克东北部进行的一项关于污染对光伏组件影响的实验研究。在五个月的时间里，测量了两个相同模块的电压，电流功率和能量曲线，并采用不同的清洁策略(一个自然积尘，而另一个定期清洁)。讨论了污染对日发电量、雨水积累和颗粒物浓度的影响。结果表明，在丰水期没有发生损失，但在干旱期由于污染，性能明显下降。此外，还发现污垢对最大功率的影响比短路电流更大。经过两个干燥的夏季，最大的电力损失高达22%。由于污染造成的日能量损失平均为16%。此外，有四个多项式模型被淹没在预测光伏组件(电压、电流、功率和能量)由于粉尘积累而退化。
