Photovoltaic Cable (Solar)

DC Solar cables are designed for connecting photovoltaic power supply systems. Essentially used for connecting the photovoltaic panels to the junction Box /Inverter. These flexible cables can be used both indoor and outdoor for flexible and fixed installations. Q-FLX DC SOLAR cables are also designed for a maximum permissible DC voltage of 1.8 Kv, Ambient temperature range of -40 °C to +90 °C and 120 °C on the conductor.
