应用案例 Application Case:NL15F-PV700

NL15F-PV700是在荷兰政府和本地电力公司的支持下,为荷兰农场光伏发电开发的高压分布式直流光伏储能系统。该系统能够实施智能电价交易,大幅缩短光伏系统的投资回收期,并已于2015年在荷兰农场应用。

Sinowatt has developed HVDC distributed PV ESS for photovoltaic power generation on Dutch farms with the support of the European Agent of Sinowatt ATEPS Nederland BV. The project is further supported by the Dutch government and local electric power company. The systems support smart electricity trading which greatly shortens clients' investment payback period and have been applied on a number of Dutch and other European farms.
