While clipping generally causes energy loss, it can help reduce additional losses during soiling by naturally limiting peak power. This study investigates the potential to optimize clipping to maximize operational profits by balancing soiling losses and clipping losses. Instead of directly minimizing clipping loss, a minimum cleaning interval is imposed as a constraint. An algorithm is proposed to determine the maximum allowable clipping, expressed as the Inverter Loading Ratio (ILR), for different soiling rates (SRT) while maintaining the minimum cleaning interval. The approach is validated using the specifications of a 10 MWp PV plant near Madurai, Tamil Nadu, India, with a daily SRT of 1 % and a minimum cleaning interval of 15 days. Results show that a higher ILR allows more soiling, while a lower ILR allows less. An optimum ILR of 1.39 delivers the highest benefit, yielding an annual net gain of €3600 by subtracting clipping related loss of revenue (LoR) from the combined cost of cleaning (CoC) and reduced LoR due to soiling loss.</div></div>","PeriodicalId":428,"journal":{"name":"Solar Energy","volume":"300 ","pages":"Article 113825"},"PeriodicalIF":6.0,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144711221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through comparative experiments simulating actual field shading conditions (single-cell shading, short-side row shading, and long-side row shading), we found that BC modules outperform TOPCon modules only when fewer than three cells in a substring are shaded. This is theoretically supported by the relationship between the breakdown voltage of BC cells (−5V) and the negative bias condition required for bypass diode activation in a substring (−15 V). In the case of short-side and long-side row shading commonly seen in large ground-mounted power stations, the output performance of the two tends to be consistent.
