In November.,2014, Ningbo Watson International Furniture Plaza, which is the largest home building materials market in Ningbo,successfullygrid production and become the largest single commercial rooftop PV projects in Ningbo area. Even more important, it is the new big exploration in large domestic commercial roof photovoltaic mode in China.
Introduced by EPC constructor that, this 800 KW capacity project accept 3200pcs 250WPanels and 49pcs Solis-15KW-2GPVInverter. Particularly worth mentioning, this PV system don’t take up any distribution field due to its string typedesign. Otherwise, the accurate MPPT tracking of “Solis” PV Inverter is very suitable forchangeable roof structure and direction.
According to conservative calculation with annual average 1050 hours effective illumination, which couldgenerate power around 840000KWH every year, allow the static return time within six years.
The projectcreated a successful case in the large commercial body application and play the competitive role in current distributed PV market.
