6mm2 (6mm squared) solar cable is a high-performance, flexible, single-core DC cable designed for photovoltaic systems. It features tinned copper conductors for maximum conductivity, double-layer XLPE/XLPO insulation for UV, water, and heat resistance, and typically supports up to 1.8kV DC (1.5kV-1.8kV). Ideal for 12V-48V or high-voltage, long-distance solar panel, and inverter connections.
