When the photovoltaic system evolves from 600V to 1000V, it brings about a significant decrease in cost and an effective increase in power generation. Similarly, when 1000V evolves to 1500V, there will be a similar efficiency improvement.

High voltage photovoltaic systems have lower line losses and higher system efficiency; Additionally, due to the increased power density of inverters and transformers, their high power and small size make them easy to install and maintain, thereby reducing overall system costs. These advantages make 1500V high-voltage systems the development trend of large-scale photovoltaic projects.

1500V TUV PV1-F Solar photovoltaic cable

Photovoltaic cable is a special cable used in the field of solar power generation, such as solar power stations and rooftop photovoltaics. It connects solar photovoltaic panels and inverters to ensure the stable operation of the entire solar power generation system.

characteristics: Cable made of electron-beam cross-linked insulation and coating; high resistance against heat , cold, oil, abrasion, ozone, UV and weather; with improved reaction in case of fire . low smoke, halogen free , flame free , flame retardant.
