Specs (STC)

Standard Test Conditions (STC) are standard test conditions that reflect the operation of a solar panel under ideal conditions. As part of the tests, the weather of a clear sunny day with an air temperature of +25 °C, no wind, solar intensity of 1000 W/m² and an emission spectrum relative to air mass of 1.5 is simulated. The surface of the solar cell must be placed strictly perpendicular to the rays from the celestial body. Note that in real operation of the solar panel, such conditions are extremely rare. However, in general, the characteristics of the STC allow us to evaluate the "passport" parameters of the energy storage device.

Power (Pmax)

The amount of electricity in watts that a solar panel produces in one hour in tests using the STC method. The panel must provide the declared number of watts during normal operation.

Nominal voltage (Vmp)

The value on the voltmeter when testing the solar panel at the nominal power level according to the STC method. The Vmp parameter is measured in volts. It stands for Voltage at Maximum Power. Allows you to determine for which type of batteries the panel is provided - for 12 V or for 24 V.

Nominal power (Imp)

Ammeter reading during solar panel testing under STC conditions. The value of the rated current Imp (Current at Maximum Power) is measured in amperes.

Open-circuit voltage (Voc)

The voltage generated by the solar battery in idle mode, that is, without connecting the load. Behind the abbreviation Voc stands for Voltage Open Circuit.

Short circuit current (Isc)

The current value under the condition of zero voltage (Short Circuit Current).

Efficiency

Percentage of the maximum solar panel power to the incident radiation power produced. The efficiency parameter allows you to determine how efficiently the panel PV module converts solar energy into direct electric current.

Operating temperature

The temperature range in which the solar module functions normally. Exceeding the specified norms in any of the directions leads to a decrease in the productivity of energy generation, accelerated degradation of the panel, and the appearance of microcracks on its surface. For most solar panels, the operating temperature range is -40°C to +85°C.

Dimensions

Dimensions of the solar panel in unfolded form.
