Abstract

This work presents a systematic annual performance evaluation of the phase change material (PCM) integrated in a photovoltaic (PV) module. A numerical model, validated against experimental data, was implemented with monthly-hourly average meteorological data, solar irradiance, ambient temperature, and wind speed, to conduct a comprehensive annual performance study. Strategic thermal management designs were developed to mitigate peak heat load during the hottest months and identify potential drawbacks in cooler months. Design criteria for PCM-based thermal management were articulated, encompassing PCM thermophysical property selection and geometries to ensure effective integration with the PV module. A temperature reduction of up to 11.3 °C emphasised the effectiveness of PCM integration in stabilising module temperature and increasing conversion efficiency. Results also indicated that increasing the PCM mass enhanced conversion efficiency for a fixed collector area, with the PCM-integrated PV module achieving an efficiency gain of 6.09 % relative to the simple PV module. A techno-economic analysis showed that integrating PCM raised capital costs (extending payback by factors of 4.8 to 231). However, it also produced annual energy-yield gains and reduced temperature-induced degradation, which supports the development of low-cost PCM composites and optimised thermal designs for scalable deployment.
基于pcm的光伏系统热管理的年度性能和技术经济评估
本研究对集成在光伏(PV)模块中的相变材料(PCM)进行了系统的年度性能评估。利用逐月平均气象数据、太阳辐照度、环境温度和风速,建立了一个与实验数据相匹配的数值模型,进行了全面的年度性能研究。开发了战略性热管理设计,以减轻最热月份的峰值热负荷,并确定较冷月份的潜在缺点。基于PCM的热管理设计标准,包括PCM热物理特性选择和几何形状,以确保与PV模块有效集成。温度降低高达11.3°C,强调了PCM集成在稳定模块温度和提高转换效率方面的有效性。结果还表明,增加PCM质量可以提高固定集热器区域的转换效率,与简单的光伏组件相比,集成PCM的光伏组件的效率提高了6.09%。一项技术经济分析表明,整合PCM提高了资本成本(将投资回报延长了4.8倍至231倍)。然而,它也产生了年能量产量的提高,减少了温度引起的降解,这支持了低成本PCM复合材料的发展,并优化了可扩展部署的热设计。
