Solar panels are rated in watts, which tells us their maximum power output under perfect conditions. Most residential panels today range between 350 and 450 watts, with efficiency reaching up to 22%. A high-efficiency, 400-watt panel will produce more electricity than a 350-watt one, even if they’re exposed to the same amount of sunlight.
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.
Multiply daily output by 30 to estimate how much kWh a solar panel produces monthly: A 350-watt panel generating 1.75 kWh daily will produce approximately 52 kWh per month. Yearly output builds on monthly numbers and reflects seasonal variations: A 350-watt panel produces between 350 and 730 kWh annually.
