How to choose cables in photovoltaic energy production systems
DC cables are mainly laid outdoors and must be resistant to humidity, sunlight, cold, UV , etc. Therefore, DC cables in distributed photovoltaic systems usually choose photovoltaic certification. Special cables, taking into account the output current of DC connectors and photovoltaic modules,
How much cable should be used for 30 kilowatt photovoltaic power generation over 600 meters
< p>1. Understand the resistivity and current load of the cable. These two parameters will determine the size of the cable length.2. Determine the number, size, and current charge of the components of the solar system. Calculate the required cable length.
3. Calculate the wire resistance based on the current load, wire specifications and wire length. Afterwards, divide this result by the length of the wire to find the resistance per meter of wire.
30 kilowatt photovoltaic power generation uses 10 square meters of copper cable over 600 meters. According to the request for relevant public information, 30 kilowatt photovoltaic power generation uses 10 to 16 square meters of copper wires and cables per 600 meters. Line voltage drop must also be considered. This is a dry start and run. the load is not heavy. Choose a line of 35 square meters. If it is a heavy load startup, the operating load is heavy, you should choose 50 square meters.
