Making solar safer for companies: the why, what and how
Improved economics, governmental incentives, and increased awareness of solar energy as a viable alternative to grid power are leading more companies to go solar. With the potential to benefit businesses large and small, smart energy solutions are cropping up on unused rooftops of shopping centres, manufacturing plants, airports, schools, and hospitals. Much of the attraction… Read more »
U.S. residential storage: a glimpse at the market
The U.S. is experiencing major growth in the energy storage market, and it’s only the beginning. According to Wood Mackenzie Power and Renewables’ U.S. Energy Storage Monitor Q2 2020, the market (residential, non-residential and front-of-the-meter) is expected to grow more than 13-fold from 523 MW in 2019 to nearly 7 GW by 2025, in spite… Read more »
Are we about to experience a DC boom with the growth of solar plus storage?
Reliability and speed of response are essential to effectively managing or preventing a crisis – especially when it comes to power supply and temperature control. This has been clearly demonstrated by the outbreak of COVID-19 with countries across the world needing to rapidly put in place the necessary infrastructure to combat the virus and subsequently… Read more »
LED引领太阳能行业发展
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。
