- NEC : See National Electrical Code.
- NEMA : See National Electrical Manufacturers Association.
- Nickel Cadmium Battery : A battery containing nickel and cadmium plates and an alkaline electrolyte.
- Nominal Voltage : A reference voltage used to describe batteries, modules, or systems (i.e., a 12-volt or 24-volt battery, module, or system).
- Normal Operating Cell Temperature (NOCT) : The estimated temperature of a photovoltaic module when operating under 800 w/m2 irradiance, 20?C ambient temperature and wind speed of 1 meter per second. NOCT is used to estimate the nominal operating temperature of a module in its working environment.
- N-Type : Negative semiconductor material in which there are more electrons than holes; current is carried through it by the flow of electrons.
- N-Type Semiconductor : A semiconductor produced by doping an intrinsic semiconductor with an electron-donor impurity (e.g., phosphorus in silicon).
- N-Type Silicon : Silicon material that has been doped with a material that has more electrons in its atomic structure than does silicon.
