A solar panel wattage calculator can help optimize your solar power system for maximum efficiency and cost-effectiveness. This calculator considers variables such as panel efficiency, sunlight intensity, and environmental conditions, allowing for a more accurate prediction of the electricity a solar panel can generate.
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.
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.
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.
