As an electrical engineer and a solar homeowner, I’ll answer this question from both a technical and real-life point of view. Most solar panels you can find today are rated between 250 and 550 watts of power. The wattage (W) is what solar manufacturers and installers put first in the product description.
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.
Typically, a 250 watt solar panel running at its maximum efficiency for 7 hours a day can provide you with 1.75 kWh of output. Again, it will depend on the sunlight and the positioning of the panel. Dive into further reading on the pros and cons of solar energy to determine the average solar panel output that can meet your needs.
PV wattage refers to the overall power output that a solar panel can provide in a specific amount of time. It is determined by factors such as voltage, amperage, and number of cells.
