对于太阳能行业来说,2020年将是值得铭记的一年。在实现2019年的强劲扩张后,由于新冠疫情的持续蔓延,太阳能行业在2020年出现了一些不确定因素。 若干趋势会一直延续到2020年及2020年以后,其中之一便是业界对基于LED的模拟器能够满足其计量需求越来越有信心。LED闪光器在2019年轰动一时,许多公司都对这项技术充满信心,许多项目的生产线末端安装了基于LED的模拟器。WAVELABS是一家总部位于德国萨克森州的制造企业,主要生产Sinus-220 LED IV型电池测试器等产品。据该公司报告,与2018年相比,其销售额增长了7倍。 LED太阳光模拟器在近几年才被市场广泛接受。此前,自工业太阳能电池制造伊始,脉冲(AC)和连续(DC)氙灯便一直是效率测定的标准光源。由于固态照明技术的突破式发展,基于LED的光源已被证明是一种更好的测量方法。主要原因在于LED能够将各种颜色结合在一起,从而更加准确、可靠地匹配太阳光谱。本文旨在揭示氙灯模拟器和LED模拟器的优缺点,以及在选择模拟器光源时需要考虑的因素。另外,本文还将阐述一些表明基于LED的技术在太阳能计量领域具有强劲趋势的其他因素。 氙光的优缺点 氙灯最突出的缺点是其与标准光谱之间存在较大偏差(如图1所示),这主要是由波长大于750nm(纳米)的氙光波峰造成的。氙光谱的偏差远远超出A级设备的允许公差,从而导致了效率测定的不准确。

于瑞士深耕动力电子设备制造 30 余年

Studer 自创立之初便一直走在储能逆变器制造的最前沿。尽管在该行业不断演变的过程中,新的竞争对手层出不穷,但 Studer 始终保持着自身的领先地位。Studer 的所有制造活动均按照最高质量标准在瑞士进行。以下,Studer 销售主管 Serge Remy 带领 PES 回顾了 Studer 30 多年的历史,并向 PES 讲述了 Studer 的现状。 开创期 以下故事的主角是一家于瑞士萌芽并逐步发展壮大的公司。 1987 年,该公司创始人 Roland Studer 萌生出一个伟大的想法:将高价值能量调节设备推向一个崭新的市场,一个当时尚处在发展初期的市场,并将该等设备销往瑞士以外的其他国家。这个崭新的市场当然就是太阳能光伏市场。 首款具有模拟显示功能的 200Wp 太阳能充电控制器问世 仅一年之后,该首款设备便经过改进而达到了高达 300Wp 的峰值功率,并集成了数字显示功能。 发展壮大期 90 年代,Studer 销售额呈现出指数增长,并开发出其首款正弦波逆变器。 Studer 的创新成果之所以能脱颖而出,是因为他们并未单纯停留于发明本身,而是积极地将发明转化为新产品、解决方案和服务,从而使自身在市场上占有一席之地。 1998 年,Studer 发明了首款内置太阳能 充电的逆变器。在接下来的十年里,其业务在全球范围内扩展至可再生能源领域的其他应用,如移动、备用和通讯系统。 2000 年前夕,地方性企业 Studer Innotec 完美转身,成为一家全球性企业。 潜心创新 Studer 自创立之初便一直以创新来定义自身。事实上,正是创新这一品质造就了 Studer。 在接下来的十年里,Studer推出业界最先进对的Xtender系列模块式逆变器,该系统开启了一系列旨在优化可用能源之利用的产品。这些产品既可用作离网逆变器、电池充电器、并网馈电设备,也可为输入电网提供能量协助。Xtender 既是一种高科技设备,又是能源系统管理的关键参与者。 瑞士制造的力量 Studer 的所有产品均在位于阿尔卑斯山中部的锡永… Read more »


1996年以来,史陶比尔光伏连接器已成功连接全球超300GW光伏系统,这一数字十分惊人。PES采访了史陶比尔电连接器股份公司管理委员会成员和全球替代能源总监Matthias Mack,谈及关于企业价值观、行业发展和未来方向等话题。 PES:很高兴能再次采访您!我们和贵司有过几次愉快的采访经历,对贵司的发展也非常感兴趣。我们一直都有许多新读者,能否请简要介绍下史陶比尔? Matthias Mack:作为一家瑞士家族企业,史陶比尔集团成立于1892年,是工业连接器(流体连接器和电连接器)、工业机器人和纺织机械这三大领域机电一体化解决方案的全球专业供应商。史陶比尔电连接器股份公司(前身为Multi-Contact)隶属于史陶比尔集团,是光伏连接器领域的资深专家和市场领导者。史陶比尔致力于提供可靠且高质量的产品与服务,以便帮助业主降低运维成本。从屋顶安装到优化器和储能,我们安全且高效的产品广泛应用在光伏系统中,不仅可以保障项目可靠性,同时能够提升其盈利能力。 PES:您认为太阳能光伏行业是否仍在高速增长?为什么? MM:从全球范围来看,分布式光伏装机和销量的增长,推动技术成本持续下降,进而加快平价上网进程。光伏从绿色奢侈品逐渐转变为具有市场竞争力的消费品。全球大型企业正在进入光伏行业,而高质量的产品必将在ROI和可融资能力驱动的市场中,赢得胜利。 今年,我们预计全球光伏新增装机105~120GW,GW级市场将超过17个。市场仍在持续增长,这一点从我们第一季度销售数据和客户需求中可以明确地感受到。疫情短期内会对市场需求有所影响,不过达到预期的安装量应该没有问题。对于2021年的市场预估还不明晰,但是我们仍然持乐观态度。 PES:今明两年,除了新冠危机,史陶比尔还会面临什么挑战?目前形势如何,未来如何发展? MM:我们拥有超过58年电连接专业经验,为不同行业提供可靠的电连接解决方案。1996年,史陶比尔发布全球第一款光伏连接器MC3。2002年,史陶比尔MC4面市,迅速得到市场认可,逐渐成为行业标准。迄今,史陶比尔MC4系列光伏连接器已成功连接超300GW光伏系统,接近全球光伏装机量的一半。史陶比尔能够快速响应多样化的市场需求,提供适合现场实际应用的解决方案。凭着出色和丰富的专业知识,我们能够妥善处理新冠危机带来的挑战。


异质结技术(HJT)是目前太阳能行业中提升太阳能电池效率和太阳能电池组件输出功率的一种最佳选择。HJT结合了掺氮晶体硅片的高质量与非晶硅薄膜层的最佳钝化效果和电荷选择特性,以及高度透明的TCO接触层,用于生产一种高性能太阳能电池,其性能超过了具有扩散发射极的传统太阳能电池,例如PERC。异质结太阳能电池由硅晶片制成,两极均使用钝化接触。由于这些非常薄的非晶硅层堆的有益能量水平、电荷载体选择性和极好的钝化特性,可能实现特别高的效率。除此之外,HJT太阳能电池非常适合双面模块应用。 与PERC或TOPCON电池相比,HJT太阳能电池的生产工艺更为简单,所需的生产步骤明显更少。而且,其组件的功率年退化率为0.45%,与PERC组件0.7%的年退化率相比要好得多。由于较高的电池效率和较低的温度系数,与传统的硅太阳能电池相比,HJT模块可提供更高的平均能量生产性能。 2019年《光伏杂志》(PV Magazine)报道了全尺寸(244cm²)双面接触异质结太阳能电池的最高效率记录,达25.11%。背面接触异质结电池26.7%效率保持了单晶体硅太阳能电池的最高记录。如今额定容量400瓦的带HJT太阳能电池的太阳能组件已经面市。 预计未来异质结电池市场会有很高的增长率。2019年的《国际光伏技术路线图》报告预计,HJT电池将在2026年占到市场份额的12%,到2029年将占至15%——十年前,只有松下一家公司生产使用该技术的产品,这种增速十分稳定。 如今,全球许多地区都已经在生产HJT太阳能电池,比如日本、新加坡、台湾、中国大陆、美国和欧洲。
