In a solar installation, a PV cable that is 100 meters long is typically used to connect the solar panels to the inverter or charge controller. The PV cable is designed to safely and efficiently transmit the direct current (DC) electricity generated by the solar panels to the rest of the system.

The PV cable used in solar installations is usually made of high-quality materials that can withstand outdoor conditions and resist UV radiation. It is also insulated to prevent any electrical hazards and ensure the smooth flow of electricity.

When installing a 100-meter PV cable in a solar system, proper care should be taken to minimize voltage drop over the long distance. This may involve using a thicker gauge cable or installing a voltage optimizer to maintain the efficiency of the system.

Overall, the PV cable plays a crucial role in the performance and safety of a solar installation, and choosing the right cable and installing it correctly are key factors in ensuring the system operates efficiently for years to come.
