中国光伏发电平价上网为期不远 土地成困扰企业难题

2017-04-24 17:57:17   经济参考报

我国光伏发电平价上网为期不远

土地问题成困扰光伏企业最大难题之一

日前于上海召开的第十一届国际太阳能产业及光伏工程展览会(SNEC)传递的信息表明,我国光伏产业技术进步日新月异,新产品、新材料、新科技、新应用层出不穷,缔造着一个又一个传奇。随着光伏发电效率和品质正在不断提升,成本持续稳定下降,光伏平价上网的脚步也越来越近。光伏从业者表示,土地问题是当下困扰光伏企业最大的难题之一。

技术进步日新月异产业发展愈加成熟

当今世界,光伏发电的新材料、新工艺层出不穷,PERC(钝化发射极背面接触)、黑硅等光伏发电新技术正在迅速普及。在第十一届国际太阳能产业及光伏工程展览会上,PERC技术被多家光伏企业作为主打展品。

晶科能源multi-wire单晶60片320瓦组件首度亮相。该款是基于PERC技术的多主栅单晶组件,最高功率达到320瓦,组件效率可到达19.55%。同时,晶科能源还推出了310瓦输出功率的N型双面组件,正反面都能发电。根据不同的地面反射率,双面组件的背反光贡献实际发电可增加10%至30%。

隆基乐叶光伏科技有限公司在去年推出Hi-MO2产品的基础上,今年在SNEC展上又推出了升级版Hi-MO2。基于Hi-MO1的低衰减技术,结合双面技术诞生的Hi-MO2首年光衰率可低于2%,平均年衰减低于0.45%。

天合光能新推出的“PERC 双核组件”产品已经获得20兆瓦组件供应订单。天合光能全球销售市场副总裁印荣方说,今年是PERC双核的市场培育期,全球出货量保守预计在300兆瓦至500兆瓦之间,以后会大幅度提高。

技术变革日新月异,推动着光伏产业愈加成熟。当前我国已成为全球最大的光伏产品生产国和应用国,在国际光伏市场担当领军者。

国际可再生能源署最新发布报告显示,2016年全球太阳能发电新增装机容量71吉瓦,同比增长32%,是增长最快的一种可再生能源。其中,近一半贡献来自中国,新增装机34吉瓦。排在第二位的美国新增装机为11吉瓦。

除规模优势外,近年来,我国光伏产业已经站在了全球技术创新的前列,在全产业链上实现全面创新,不断刷新历史纪录,同时还积极参与国际标准制定。截至目前,天合光能主导和参与标准制定64项,其中已发布标准46项,包括主导国际标准四项、国家标准一项、行业标准两项。

4月17日,协鑫、天合光能等光伏企业共同发起并筹建“国际绿色能源(上海)创新中心”,意在为清洁能源的研发和应用搭建起全球运营网络,形成产、学、研联盟。创新中心将致力于光伏器件、材料及系统应用技术的创新和产业化服务工作,并将作为全球性的协同创新中心,集研发、工程、市场、孵化于一体。
