How many Watts Does a solar panel produce?

Solar panel power output can get confusing fast. Is 400 watts good? 420 watts? Should you opt for the 450-watt panel? Is it worth the extra cost? About 97% of home solar panels installed in 2025 produce between 400 and 460 watts, based on thousands of quotes from the EnergySage Marketplace.

What is solar wattage?

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.

How many Watts Does a solar panel produce in 2025?

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.

How much power does a home solar panel produce?

About 97% of home solar panels included in EnergySage quotes today have power output ratings between 400 and 460 watts. The most frequently quoted panels are around 450 watts, so we'll use this as an example.
