What resistance meter should be used for photovoltaic solar installation
What DC Wire Sizes to use for your Solar PV System?
Choosing the right wire sizes in your Solar PV system is essential for both performance and safety reasons. If the wires are undersized, there will be a significant voltage drop in the wires resulting in substantial power loss. Also, if the wires are undersized, there is a risk that the wires may heat up to the point in which a fire may result.
