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 Power”, “Maximum Power”, or “Pmax”, and it’s measured in watts or kilowatts. .
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. .
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. For instance, the 100-watt solar panel from our example has an Imp rating of 5.62 Amps. This means that when this solar panel is producing 100 Watts of power under Standard Test Conditions, It will be generating 5.62 Amps of current. [pdf]
