For example: A 100-watt panel can produce 100 watts per hour in direct sunlight. A 400-watt panel can generate 400 watts per hour under the same conditions. This doesn’t mean they’ll produce that amount all day, output varies with weather, shade, and panel orientation.
A 400-watt panel can generate roughly 1.6–2.5 kWh of energy per day, depending on local sunlight. To cover the average U.S. household’s 900 kWh/month consumption, you typically need 12–18 panels. Output depends on sun hours, roof direction, panel technology, shading, temperature and age.
The daily energy production of a 100-watt solar panel is influenced by the amount of sunlight it receives. On average, you can expect: Assuming 5 peak sun hours: 100W × 5 hours = 500 watt-hours (0.5 kWh) per day. In optimal conditions: The panel may produce up to 600-700 watt-hours (0.6-0.7 kWh) daily.
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.
