          應用案例 Application Case:NL15F-PV700

          NL15F-PV700是在荷蘭政府和本地電力公司的支持下,為荷蘭農場光伏發電開發的高壓分布式直流光伏儲能系統。該系統能夠實施智能電價交易,大幅縮短光伏系統的投資回收期,并已于2015年在荷蘭農場應用。

          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.
