封面故事 太阳能逆变器是并网发电关键,合肥阳光冒尖 » 上接42页 小功率型号上使用,且大多为离线产 品;再例如大功率逆变器技术,目前 国内很少有企业能开发出百千瓦级以 上的产品;双向逆变器技术,国内企 业中仅有阳光电源有类似的产品;此 外,还有模块化设计技术,以及性能 稳定性等等关键性技术,本土供应商 都存在明显差距。 虽然目前国内还没有形成太阳能 发电市场规模,本土供应商起步较 晚,并且产品主要依靠出口欧美日 韩市场,但从长期发展来看,本土供 应商存在很大的市场机会。张明峰指 出,这主要取决于低廉的生产成本, 研发水平的提高,本地的技术支持和 维护,以及上下游产业链的整合等关 键因素。 如何提高光伏发电效率? 由于各国政府推出激励政策和传统电 力成本的不断攀升,越来越多的家庭 开始注意太阳能,并在屋顶安装光伏 SPV1020用一颗单芯片即可取代离散组件网络, 优化系统性能。 (PV)发电系统。光伏发电系统的投 资回报取决于该系统每年的发电量, 因此用户需要的光伏系统必须具备高 效、可靠和易于维护等特性,从而可 以获得最大限度的发电量。 “很多安装光伏发电系统的用 户已经意识到部分或间歇性的遮蔽 会影响到系统的发电量。” NSC的 Michele Sclocchi在关于SolarMagic 技术如何提高太阳能光伏系统的效率 的技术文章中表示,并进一步分析了 太阳能光伏系统由于部分电池板受到 遮蔽而产生发电量下降的问题。他认 为,当树木、烟囱或其他物体投射的 阴影遮挡住光伏系统时,就会导致系 下接48页 » HALF PAGE AD (horizontal) 215mm x 139mm 46 国际电子商情 | 2010年8月 | www.esmchina.com
