Nameplate capacity, also known as the rated capacity, nominal capacity, installed capacity, maximum effect or gross capacity, [1] is the intended full-load sustained output of a facility such as a power station, [2] [3] electric generator, a chemical plant, [4] fuel plant, mine, [5] metal refinery, [6] and many others. Nameplate capacity is the ...
A rating plate on a machine carries information about its operational limits. The plate frequently contains the names of the machine and its manufacturer, so the rating plate is often called a name plate (hence the term "nameplate capacity" for a generator), although many devices carry separate nameplates and rating plates.

The capacity credit can be much lower than the capacity factor (CF): in a not very probable scenario, if the riskiest time for the power system is after sunset, the capacity credit for solar power without coupled energy storage is zero regardless of its CF [3] (under this scenario all existing conventional power plants would have to be retained after the solar installation is added).
At the low range of capacity factors is the photovoltaic power station, which supplies power to the electricity grid from a large-scale photovoltaic system (PV system). An inherent limit to its capacity factor comes from its requirement of daylight , preferably with a sun unobstructed by clouds, smoke or smog , shade from trees and building ...
The highest power thus measured is the 'nominal' power of the module in watts. This nominal power divided by the light power that falls on a given area of a photovoltaic device (area × 1000 W/m 2) defines its efficiency, the ratio of the device's electrical output to the incident energy.
Nominal power is the nameplate capacity of photovoltaic (PV) devices, such as solar cells, panels and systems, and is determined by measuring the electric current and voltage in a circuit, while varying the resistance under precisely defined conditions.
The curve represents a boundary of all operating points in the MW/MVAr plane; it is typically drawn with the real power on the horizontal axis, and, for the synchronous generator, resembles a letter D in shape, thus another name for the same curve, D-curve. In some sources the axes are switched, and the curve gets a dome-shaped appearance.
The maximum power measured is the nominal power of the module in Watts. Colloquially, this is also written as "W p"; this format is colloquial as it is outside the standard by adding suffixes to standardized units. The nominal power divided by the light power that falls on the module (area x 1000 W/m 2) is the efficiency.
