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. The wattage ratings of solar panels indicate the maximum energy they can produce when exposed to direct sunlight5. [pdf]
