About 97% of solar panels quoted on the EnergySage Marketplace in 2025 are 400 to 460 watts—expect to see panel outputs in this range in your quotes. Your panels' actual output will depend on your roof's shading, orientation, and hours of sun exposure. 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. . Due to these factors, you can expect a solar panel to operate at about 60% to 75% of its rated capacity under real-world conditions. For instance, a 100W panel may produce 60W-75W in direct sunlight on a typical day. In this guide, we'll walk you through realistic production numbers, show you how to calculate output yourself, and explain what actually affects performance in the real world. It is the secret to determining your system size, savings and ROI. The market has steadily moved toward higher efficiency models, with 450W panels. .
