assigned quantity used for specification purposes indicating a specific characteristic of a PV system or component established for a specified set of operating conditions
NOTE 1 See also IEV 151-16-08
a) rated capacity
see "capacity/rated capacity", 3.4.10d)
b) rated condition
conditions under which a manufacturer states a specific operating characteristic of a product
c) rated current
(Symbol: IR ) (Unit: A)
electric current produced by a PV device at a rated voltage under specified operating conditions
d) rated efficiency
(Unit: dimensionless, usually expressed as a percentage, %)
efficiency of a component at specified operating conditions
e) rated load
electric load required to achieve the rated output power of a PV system or its PV devices, or components
f) rated power
(Symbol: PR) (Unit: W)
electric power produced by a PV device or other PV system component under specified operating conditions
g) rated power at STC
(Symbol: Pstc) (Unit: W)
electric power delivered by a PV device at its maximum power point at standard test conditions, STC
NOTE 2 Rated power at STC is colloquially, but incorrectly referred to as "peak power"
NOTE 3 See also "conditions/standard test conditions", 3.4.16e)
h) rated power at SOC
(Symbol: Psoc) (Unit: W)
electric power delivered by a PV device or system under standard operating conditions
i) rated sun-hours
(Unit: h)
amount of time that the solar irradiance is at reference levels
NOTE 4 Rated sun-hours is usually expressed on a daily basis
NOTE 5 If GI,ref = 1 kW ´ m–2 then "rated sun-hours" over any period of time is numerically equal to the irradiation over the same period as expressed in kWh ´ m–2
j) rated system power
Pertaining to stand-alone PV systems: system power generated when connected to a rated load
Pertaining to grid-connected PV systems: system power that can be generated under standard operating conditions, SOC
NOTE 6 See also "conditions/standard operating conditions", 3.4.16d)
k) rated voltage
(Symbol: VR) (Unit: V)
voltage at which a generator is designed to generate maximum electricity under specified operating conditions |
