Cables and connectors are vital parts of a PV array. The selection of cables is an important procedure, but how the cables are managed thereafter also influences how the entire PV system will function. Poor cable management can ultimately lead to problems.
Cables were the culprits in two fires that happened in PV arrays, one in Bakersfield, California in 2008 and one in Mount Holly, North Carolina in 2011. Bill Brooks from Brooks Solar prepared a paper for the Solar America Board for Codes and Standards explaining the causes of the fires. In both cases, cable insulation damage was identified as the root cause. A significant amount of work goes into the complex process of designing and planning a PV power plant, whether on the rooftop of a building or ground-mounted on the field. This then translates into an efficient, working PV power plant in situ. With the rapid uptake of PV, it is also common to see homeowners who design and implement their own small PV rooftop projects. With so much already invested, it would be vexing if careless cable management after installation lead to losses. And dangling, untidy cables are simply unaesthetic.

Zinc is naturally found in elements such as air, water, and soil as well as in plants, animals, and humans. It is the 27th most abundant element in the Earth’s crust and is infinitely recyclable without the loss of its properties, making it a true renewable resource.
Zinc’s ability to protect iron and steel products from corrosion has been known for centuries as the material has been used in construction since the second century. More than 13 million tons of zinc is produced annually worldwide—70 percent of which is from mined ores and the remaining is from recycled sources. More than half of this annual production is used in zinc coatings to protect steel from corrosion.
