Solar panel wattage refers to the manufacturer’s solar panel rating that determines the maximum electrical power (direct current) the panel generated under standard test conditions (STC) in the lab. 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.
However, real-world applications require more sophisticated calculations accounting for environmental factors, system losses, and performance degradation. Most residential panels in 2025 have a solar panel wattage rating between 350 and 480 watts, with installers offering panels ranging from 390 to 460 watts on average.
Solar panel wattage is the lab fixed rating. Solar panel output, on the other hand, is the actual DC power the panel will generate in the real world. In general, the solar panel output is usually lower than the rated solar panel wattage. What factors affect the solar panel output? Heat, shade, dust, tilt/orientation, weather, and sunlight strength.
With residential panels reaching 480 watts and commercial systems demanding precise efficiency calculations, mastering these fundamentals directly impacts your installation success and client satisfaction. Solar panel wattage calculation represents the maximum electrical power a photovoltaic module can produce under Standard Test Conditions (STC).
