Wattage refers to the amount of electrical power a solar panel can produce under standard test conditions (STC), which simulate a bright sunny day with optimal solar irradiance (1,000 W/m²), a cell temperature of 25°C, and clean panels. In simpler terms, a panel’s wattage rating tells you its maximum power output under ideal conditions.
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 peak (kWp).
Under STC, the tested panel produced the rated wattage under 1,000 watts per square meter of sunlight, 25°C cell temperature, and 1.5 air mass. Simply put, the solar panel wattage directly determines how much electricity a rooftop solar system can produce.
The size of solar panels varies, with no definite answer. Their wattages also differ as each system operates on different power levels. To learn more about solar panel sizes and wattage, keep reading.
