Allied Wire and Cable's line of Solar Cables and Wind Turbine Cables consists of WTTC rated Wind Turbine Cables and Solar PV Wire. Designed as green energy cables, these solar cables and wind turbine cables are designed to perform to the highest standards in environmentally friendly cable applications.


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. PVC wire is also 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.

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 does not have the added construction strength of more specialized solar cables.

Wind Turbine Cables are green energy cables used in wind turbine cable applications. All of our wind farm cables are rated WTTC cables. Wind farm cables are designed to endure challenging wind farm cable environments and are flexible and easy to install. Wind farm cables are also resistant to oils, chemicals, fuels, solvents, and abrasion. They are also recyclable. Our wind farm cables are made in the U.S. From Megaflex Wind Farm Cables to Standard Flex Wind Farm Cables, WTTC VFD Wind Farm Cables, and everything in between.
