Solar Cables

DEP Power’s line of Solar Cables & Wind Farm Cables consists of WTTC rated Wind Farm Cables, Solar Cables, and Alpha’s EcoWire™, an environmentally friendly cable alternative to PVC hook-up wire. Designed as green energy cables, these solar cables, wind farm cables, and other environmentally friendly cable options are designed to perform to the highest standards in environmentally friendly cable applications.

Solar cables are part of our green energy cable inventory. Solar cables such as Photovoltaic Wire (PV Wire) and USE-2 Solar Cables are used as wiring for solar panels and photovoltaic arrays. Solar cables may also be used with underground service entrances and to connect solar cable service terminals. USE-2 solar cables are crush and impact resistant, but PV Wire has thicker insulation and jacketing, and is more sunlight, ozone, and UV resistant. PV Wire is also more flame resistant and more flexible at low temperatures than USE-2. PV Wire can be used in ungrounded or grounded photovoltaic arrays, but USE-2 Solar Cables may only be used in grounded solar cable arrays. USE-2 Solar Cables have been used for a long time, but PV wire is a relatively new addition to the world of solar cables. PV Wire first appeared in the 2008 NEC.


THHN wires are also sometimes used as solar cables in environmentally friendly cable applications. THHN is less expensive than other solar cables, but should never be used where USE-2 Solar Cables or Photovoltaic Wire are specified. Although it can be used in some of the same applications as solar cables, it doesn’t have the added construction strength of more specialized solar cables.
