The researcher's activities were performed to classify PV panel cooling systems. The review illustrated the effect of the cooling system on the PV panel's thermal management, PV panel efficiency, and PV panel output power. The study focuses on the review of active, passive, and hybrid cooling system applications. The effects of different PCM materials and PCM containers on the PV panel passive cooling system are investigated experimentally and numerically. PCM material simulation is difficult, so the study analyses the available simulation methods and their advantages and disadvantages. The PV panels' active cooling system is very sufficient in both thermal management and energy efficiency. The review also summarizes each cooling technique's advantages and disadvantages for optimum model design and material selection. The study discovered that combining two or more cooling systems increases system efficiency by transferring energy from one to the other.","PeriodicalId":282260,"journal":{"name":"Advances in Structural Mechanics","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128779124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study focuses on the selection of the PCM, which is integrated as a heat source for the active device. PCM melting temperatures and latent heat control the amount of heat transferred from PV panels, which affect the PV panels' output. So, the selection of a suitable PCM with suitable characteristics will increase the cooling system's efficiency. The analysis of simulation results to optimize the best PCM characteristics found that the RT25 PCM presents maximum PV output power and minimizes PV panel temperature. Otherwise, the best PV panel performance is achieved when the PCM melting temperature is close to the ambient air temperature and the PCM solidification temperature is close to the water flow temperature.","PeriodicalId":282260,"journal":{"name":"Advances in Structural Mechanics","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133782108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
