No, Wind Energy Asia is vital to the development of the supply chain in Taiwan PES brings you a review of Wind Energy Asia 2020, which took place from March 3rd -5th and a look at forward to the upcoming edition in 2021. In mid-February 2020, as the show approached, the coronavirus spread was heating up and headed straight to be declared a pandemic. Many European exhibitors were having difficulties imagining getting on a plane and flying to an island just 100 plus miles from China, where it all had started and was still far from under control. In Taiwan however, with no community spread to speak of, the virus situation was very much under control. And we knew that, despite the pandemic, renewables continued to need development and that a strong supply chain in Taiwan was critical for the continued development of the industry here. So, despite the many skeptics, we went ahead. And were rewarded grandly! All our numbers were up handsomely, yes, up, in 2020, imagine, compared to 2019: • 52.8% more companies exhibiting, 136 in total. About 10-15 others canceled days before due to the pandemic • 13 countries and 8 pavilions: up from 6 last year • Exhibition area grew 29.7%

The declaration of a climate emergency in Scotland, quickly followed by the rest of the UK, has been a boon for the renewable energy sector. After all, without clean power, heat and transport fuels, our ambitious net-zero targets are totally out of reach. But we know tackling the carbon emissions caused by our increasing demand for energy isn’t enough on its own. The world’s raw resources are limited. As demand for these resources increase, supplies deplete, driving up costs. It’s imperative that we change the way we use products and materials, and Scotland’s ambition for a circular economy shows we are committed to making that change. The circular economy represents an opportunity to move away from the linear approach of creating and delivering a product or service that is disposed of at the end of its life. This waste represents an enormous pool of resources that can be exploited with minimal impact on the environment. A circular economy focuses on responsible production: businesses which supply products and services get the maximum life and value from the resources used to make them, keeping these resources in a continuous loop of re-use. Doing that can take a number of forms: • from re-use and repair -where a product’s

Here is the second unmissable PES show preview. In a couple of weeks, the 14th edition of Offshore Energy Exhibition & Conference opens its virtual doors! Enough said about the challenges and limitations that Covid-19 poses to all of us and our industry. Much can be done, especially online, to connect with our peers, have experts inform us about the latest ideas and technologies and grab the attention of our customers without showing them our products and services in person. At OEEC’s first virtual edition, all this and more is possible. Have a look below at what to expect after logging in on 27th - 28th October. What to expect? OEEC creates the perfect opportunity for people working in the offshore energy industry to establish new business relationships and maintain existing ones. You can expect plenty of interaction, information, presentations and innovations, lots of which will be live-streamed. We built a studio in RAI Amsterdam from which talk shows and discussions will be recorded and broadcasted. In summary, OOEC 2020 offers: 1. Offshore Energy Talks (with experts) 2. Showcases and presentations from companies 3. Live Talk Shows (with industry panels) 4. Round table sessions (organise an exclusive session about a topic of your own choosing) 5. Offshore

By 2040, it is expected that around 4GW of the UK’s onshore wind capacity will be repowered projects. The next few years will see slow growth in this sector, around 100MW per year from 2020, but increasing to around 500MW per year by 2035. So as a significant number of wind turbines begin to reach the end of their original planned life service, our attention is focussed on the topic of life management strategies to support owners make smart business decisions about the next phase of their wind farms. The decision on life extension is complex and inevitably includes technical, economic and legal considerations as well as acknowledging uncertain future electricity market prices and revenue streams, which determine if life extension is economically feasible. Decommissioning, repowering or continued operation are the main options to be considered and although wind turbines are generally designed for a service life of 20 years, many can continue to operate past their original design life. As the size and capacity of turbines increase, and technology continues to improve, the economic case for life extension is likely to become clearer. In fact, the lifetime of a wind turbine can often be extended by minor and low-cost

It is not an understatement to say that 2020 has been one of the most turbulent years in recent history, with the Covid-19 pandemic leading to seismic shifts in industries the world-over. But despite significant supply chain disruption, the renewables industry has remained remarkably resilient compared to conventional power and wider infrastructure asset classes. A growing variety of investors have subsequently entered the space, expecting to grab a slice of the pie and reap the dual benefits of non-correlated returns and greener credentials. But the renewable energy market is not so black and white. Broader trends at play in the space are generating new investor needs, and renewables owners must adapt their offerings to meet these accordingly. Indeed, the renewables market has been undergoing a shift of its own amid the phase out of state-backed subsidies, with portfolios growing more diverse and owners adopting more merchant-led approaches. This has raised several new challenges in the industry as projects have become increasingly exposed to volatile power prices. Whilst the renewables sector has continued to perform strongly during the pandemic, the coronavirus has brought these new market risks to the fore, and developers and renewables project owners now need to provide investors with confidence around the

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。

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 (Sion) 工厂中开发、制造和测试,确保具有瑞士品质。这意味着,Studer 的每一个产品都能得到全面控制,无论是开发和制造过程的控制,还是发货前最终测试过程的控制。
