Understanding Solar Panel Efficiency: How Each New Panel Produces 341.6 W In today’s growing renewable energy landscape, solar power stands out as a leading solution for sustainable, clean electricity. One key metric that home and business owners look for is wattage output—specifically, how much power each solar panel produces. A frequently cited figure is 341.6 watts per panel, but what does this truly mean, and why is it important? ### What Does “Each New Panel Produces 341.6 W” Mean? The specification “341.6 W” refers to the standard electrical output of a solar panel under standard test conditions (STC). These conditions include sunlight intensity of 1,000 watts per square meter, a cell temperature of 25°C (77°F), and an air mass of 1.5 spectrum. At these idealized conditions, a standard residential solar panel typically generates around 340 watts, close to the 341.6 W figure commonly referenced in product datasheets.
