About Current and voltage of photovoltaic panels

Solar panels receive their ratings under specific testing conditions known as "Standard Testing Conditions" or "STCs". These conditions serve as the industry standard for evaluating solar panels, making it easier to compare panels accurately.

The Wattage rating of a solar panel is the most fundamental rating, representing the maximum power output of the solar panel under ideal conditions. You’ll often see it referred to as “Rated.

Solar panels come with two Current (or Amperage) ratings that are measured in Amps: 1. The Maximum Power Current, or Imp for short. 2. And the Short Circuit Current, or Isc for short. The Maximum Power Current rating (Imp).

Solar panels are classified by their nominal voltages (e.g., 12 Volts or 24 Volts), but these voltages are only used as a reference for designing solar systems. For example, the following solar panel is classified as a 12 Volt.
