The power output of a solar panel is measured in watts (W) or kilowatts (kW). The amount of power produced by a solar panel depends on various factors such as type of solar panel, size, efficiency rate, average lifespan, number of modules.
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-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.
For example, if you have a setup with 20 solar panels, each rated at 300 watts, the total power output would be 6,000 watts, which is equivalent to 6 kilowatts (kW). However, Commercial and utility-scale solar installations can produce significantly more power per day due to their larger size and advanced technology.
