探究太阳能光伏设备故障
撰稿人：Richard Gledhill，DNV 能源系统部澳大利亚项目工程和尽职调查部门主管 即使是小故障，也会对太阳能项目的持续运行产生严重广泛的影响。如果您能知晓故障起因，就可以采取措施，防止问题重复出现。但是，随着太阳能行业迅猛发展，新技术陆续引入，并且项目时常部署在严苛甚至极端的条件下，查明故障原因成了一大挑战。 多种多样的材料和部件共同构成了太阳能光伏电站：光伏组件、安装部件、太阳能跟踪支架、逆变器、电力电缆、变电站以及越来越多的储能电池。它们暴露在不同程度的太阳辐射、风雨、冰雹、霜雪、盐分、湿气乃至摩擦等机械因素下，这些因素均会诱发金属疲劳、腐蚀、开裂等问题，对系统完整性造成了隐患。 公用设施规模的太阳能资产通常资本投入大，运营成本低，这就要求电站运行寿命达到30年以上，才能收回初期投资和后续为减少性能衰减而产生的资本支出。因此，了解太阳能系统和太阳能发电厂的故障源头至关重要，弄清原因后才能稳定供应经济的可再生太阳能电力，助力全球能源系统脱碳。
薄膜产品的可持续性
自从去年与 DuPont Teijin Films 欧洲、中东和非洲光伏市场经理 Steve Davies 和在 Coveme 光伏太阳能和特种薄膜部门负责欧洲、中东和非洲市场的业务经理 Alessandro Anderlini 对话以来，产品可持续性和可靠性相关问题的解决情况如何，我们在 2022 年及以后还能期待什么？PES 与这二位进行了访谈以了解最新情况。 PES：感谢 Steve 和 Alessandro 抽出时间再次参与我们的访谈。在去年的采访中，二位都强调了无卤素背板所具备的可持续性优势。 二位能否详细介绍一下你们产品的良好使用记录，以及这与你们的可持续性策略的契合程度？ Steve Davies: 我认为在讨论可持续性时，我们必须关注产品的性能，因为如果不能在组件的整个生命周期内保护组件，就称不上是可持续背板。2008 年，我们与 Coveme 合作，首次将 Mylar® UVHPET™ 系列产品实现了商业化。从那以后，我们的产品已经保护了 2 亿多个组件，并且没有报告过任何现场故障。
高容性光伏组件电流-电压特性检测研究
撰稿人：王健全1，仇雷飞1，林福苗1 （1. 中检集团南方测试股份有限公司，518055） 摘 要：随着高容性光伏组件市场化进程不断提速，解决容性效应引起的检测结果失真问题变得越来越重要。根据容性作用机理可知，高容性光伏组件的正反扫描I-V特性参数的差异可以反映容性所引起的误差。本文采用宽脉冲测试法和动态I-V测量法对HJT和Topcon等高容性光伏组件进行检测，研究扫描方式、电压扫描速率对于不同类型组件容性误差的影响，为高容性光伏组件I-V特性检测提供参考。 关键词：高容性光伏组件；电压扫描速率；线性扫描；阶梯式扫描
