The power of the Sun at the Earth, per square metre is called the solar constant and is approximately 1370 watts per square metre (W/m 2). The solar constant actually varies by +/-3% because of the Earth's slightly elliptical orbit around the Sun. Divide the solar panel wattage (for 100W, 150W, 170W, 200W, 220W, 300W, 350W, 400W, 500W) by the solar panel area to get the solar panel output per square foot for a specific solar panel. Here is the equation:. . Solar irradiance is the power per unit area (surface power density) received from the Sun in the form of electromagnetic radiation in the wavelength range of the measuring instrument. Solar Irradiance and Solar IrradiationWhat is Solar Irradiance, and what does it mean when dealing with solar photovoltaic. . The luminosity of the Sun is about 3.
