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.The maximum power of photovoltaic panels, often referred to as peak power, is the highest electrical power output that a solar panel can produce under standard test conditions (STC), which include a solar irradiance of 1000 W/m² and a cell temperature of 25°C. This maximum power point (MPP) is calculated by multiplying the maximum voltage (V mp) by the maximum current (I mp) of the panel2. Typically, the nominal power of a photovoltaic system is expressed in watts peak (Wp)4.
