Recently, the A-share photovoltaic "leader" Oriental Risen Energy launched its 1500V series photovoltaic module products
.
This series of products came into being
in the context of "photovoltaic subsidies gradually decreasing, owners paying more and more attention to photovoltaic power plant LCOE (kWh cost), and seeking power station cost reduction".
It is understood that compared with conventional modules in the power station terminal, the number of modules per string can be increased from 22-25 under conventional 1000V voltage to 33-37 after the DC side voltage rises, which can reduce the overall number of strings in the power station, reduce cable usage, and reduce cable loss by more than 0.
25%; From the perspective of the system, the higher input and output voltage levels reduce the AC and DC side line loss and the low-voltage side winding loss of the transformer, and according to relevant calculations, the system efficiency PR value of the power station is expected to increase by 1.
5%-2%; At the same time, the power density of electrical equipment (combiner box, AC and DC distribution cabinet, inverter) is improved, the cost of single-watt electrical equipment is reduced, the workload of installation and maintenance is reduced, and the total initial investment cost of the power station is reduced by about 0.
2 yuan/W
.
In addition, the 1500V series photovoltaic module products designed by Risen Energy according to the latest safety requirements have safer clearances and creepage distances, and match the BOM of 1500V special materials, and the series of module products have passed the full set of tests in the TUV laboratory and meet the latest class A requirements
of IEC61730.
