6 FAQs about [Laying of DC lines for photovoltaic panels]

What is the laying of DC cables in photovoltaic power generation projects?

The laying of DC cables in photovoltaic power generation projects mainly includes laying through pipes, laying in troughs, laying in cable trenches, laying in tunnels, laying directly buried sand and laying bricks, etc. The laying of AC photovoltaic cables is similar to the laying of general power systems.

How to choose a photovoltaic cable laying method?

To The photovoltaic cable laying method should consider factors such as cable specifications, number, engineering conditions, and laying environment, and should be selected according to the principles of reliable operation, easy maintenance, and reasonable technology and economy.

Where are DC photovoltaic cables used?

DC photovoltaic cables are generally used between photovoltaic modules, between strings and DC combiner boxes, and between combiner boxes and inverters. Cables require a small cross-sectional area and a large number of cables. Generally, the cables are tied along with the component support or buried directly through the pipe.

How to choose a DC cable for a PV system?

Plant owners need to ensure that the size of the DC cable installed is carefully and correctly chosen for the current and voltage of the PV system. The cables used for wiring the DC section of a grid-connected system also need to withstand the extremes of the environmental, voltage and current conditions under which they operate.

What is the difference between AC and DC photovoltaic cables?

The laying of AC photovoltaic cables is similar to the laying of general power systems. DC photovoltaic cables are generally used between photovoltaic modules, between strings and DC combiner boxes, and between combiner boxes and inverters. Cables require a small cross-sectional area and a large number of cables.

Can a DC cable be used for a grid-connected PV system?

Cables used for wiring the DC section of a grid-connected PV system also need to withstand potential extremes of environmental, voltage, and current conditions. This includes the heating effects of both current and solar gain, especially if installed near the modules. Here are some crucial considerations.
