We usually measure or convert the watts into amps of solar panels to figure out how much current (amps) is being stored in the battery. Or we measure the amperage of the solar panel. To calculate the current when your solar panel is generating its maximum power, you need to divide the maximum rated power of the panel in watts by the maximum power voltage (Vmp) which is also in volts. You can find the wattage of your panel on the back of it, or in the installation manual. [pdf]

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. .
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. .
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. .
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. The rated operating voltage is 17.2V under full power, and the rated operating current (Imp) is 1.16A. Multiplying the volts by amps equals watts (17.2 x 1.16 = 19.95 or 20). Power and energy are terms that are often confused. [pdf]
