A 400 W solar panel can produce around 1.2-3 kWh or 1,200-3,000 Wh of direct current (DC). The power produced by solar panels can vary depending on the size and number of your panels, their efficiency, and the climate in your area. How many solar panels are needed to run a house? On average, 15-20 solar panels of 400 W are needed to power a house.
Let’s demystify it. What Does Solar Panel Wattage Mean? 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.
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 300-watt solar panel will produce anywhere from 0.90 to 1.35 kWh per day (at 4-6 peak sun hours locations). A 400-watt solar panel will produce anywhere from 1.20 to 1.80 kWh per day (at 4-6 peak sun hours locations). The biggest 700-watt solar panel will produce anywhere from 2.10 to 3.15 kWh per day (at 4-6 peak sun hours locations).
