NEC solar cables are designed for connecting the photovoltaic panels generating DC i.e. direct current. These wires are suitable for a nominal DC voltage of 1.5kV. These cables can be used indoors & outdoors and have high mechanical strength to survive the extreme weather conditions which arise in any fixed, mobile, roof or architecturally integrated photovoltaic installation.
They are designed and tested to operate at a maximum conductor temperature of 90°C and for 20,000 hours up to 120°C therefore, the expected period of use is 30 years under normal usage conditions.
