Let’s demystify it. What Does Solar Panel Wattage Mean? 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.
About 97% of home solar panels installed in 2025 produce between 400 and 460 watts, based on thousands of quotes from the EnergySage Marketplace. But wattage alone doesn''t tell the whole story. In fact, efficiency matters more than wattage when comparing solar panels—a higher wattage can simply mean that a panel is larger.
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.
The fundamental formula for calculating solar panel wattage is: Wattage = Voltage × Current When applied to solar panels, this can be expressed as: Solar Panel Wattage = Vmp × Imp Where: Vmp represents the voltage at maximum power point, indicating the optimal voltage level at which the panel operates most efficiently.
