6 Frequently Asked Questions about “Solar panel nominal power”

What is nominal power?

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.

What are the parameters associated with a solar panel?

There are several terms associated with a solar panel and their ratings such as nominal voltage, the voltage at open circuit (Voc), the voltage at maximum power point (Vmp), open circuit current (Isc), current at maximum power (Imp), etc. All these parameters are crucial to know before purchasing or installation of solar panels.

What are the specifications of a solar panel?

Solar panels or photovoltaic (PV) modules have different specifications. There are several terms associated with a solar panel and their ratings such as nominal voltage, the voltage at open circuit (Voc), the voltage at maximum power point (Vmp), open circuit current (Isc), current at maximum power (Imp), etc.

When does the power of a solar module exceed the nominal power?

The power a module generates in real conditions can exceed the nominal power when the intensity of sunlight exceeds 1000 W/m2 (which corresponds roughly to midday in summer in, for example, Germany), or when sun irradiation close to 1000 W/m2 happens at lower temperatures.

What is the efficiency of a solar panel?

Most solar cells available in the market offer an efficiency of 17-19% and the highest efficiency of a commercial solar panel is about 23%. The fill factor (FF) denotes the efficiency of a solar cell. It is denoted by the ratio of maximum power point (MPP) to the product of short circuit current (Isc) and open circuit voltage (Voc).

Why is nominal power called peak power?

Nominal power is also called peak power because the test conditions at which it is determined are similar to the maximum irradiation from the sun. Thus this quantity approximates the theoretical maximum production of the panel on a clear sunny day with the panel oriented perpendicular to the sun.
