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.
Is it better to have a single cable trench or a double cable trench in a PV plant?
The length is estimated based on the actual site requirements. You're talking about length. cable thickness, which is usually calculated per square meter. The cable should not carry more than 5 amps of current. The size of the currentnt should be determined based on the parameters marked on the back of the photovoltaic panels you are using. When photovoltaic panels are connected in series, the size of the current remains unchanged, and when photovoltaic panels are connected in parallel, the currents are. added. Generally, just use the wires that came with the components between the components. The combiner box components are all connected in series, just use 4mm? Since the combiner box to the inverter is connected in parallel, it depends on how many groups you have. actually connected.
Double bars are better. Compared to a single cable trench, double cable trenches can provide better safety and reliability, while better protecting cables and reducing the risk of breakdowns. In addition, double cable trenches can better support the weight of cables, reduce the pressureion on the foundations and reduce the risk of foundation settlement. Therefore, the use of double cable trenches is a more common and reliable choice when constructing photovoltaic power plants.
