Nominal power (photovoltaic)

OverviewStandard test conditionsUnits Conversion from DC to ACPower output in real conditions

Nominal power (or peak power) is the nameplate capacity of photovoltaic (PV) devices, such as solar cells, modules and systems. It is determined by measuring the electric current and voltage in a circuit, while varying the resistance under precisely defined conditions. The nominal power is important for designing an installation in order to correctly dimension its cabling and converters. Nominal power is also called peak power because the test conditions at which it is determined are sim
