A PV module is tested and rated based upon the following values which can be found printed on the module or in its specifications sheet:
Open circuit voltage (Voc) – The voltage that the module will produce under STC when it is in an open circuit (disconnected, no current flow).
Short circuit current (Isc) – The current that a module will produce under STC when it is short-circuited. (All available curent flowing with minimal resistance, for example when the positive output of a PV module is connected directly connected to its negative).
Maximum power voltage (Vmp) – The voltage that the module will produce when connected to a circuit under STC.
Maximum power current (Imp) – The current that the module will produce when connected to a circuit under STC.
Temperature coefficient of power (Tkpmp) - A coefficient that accounts for how module power responds to increases and decreases in temperature in %/°C or V/°C.
Temperature coefficient of open circuit voltage (Tkvoc) - A coefficient that accounts for how module voltage responds to increases and decreases in temperature in %/°C or V/°C.
