How much irradiation from the sun is required to generate solar power?

Solar Irradiance. The amount of energy striking the earth from the sun is about 1,370W/m 2 (watts per square meter), as measured at the top of the atmosphere. This is the solar irradiance.The value at the earth''s surface varies around the globe, but the maximum measured at sea level on a clear day is around 1,000W/m 2.The loss is due to the fact that some of the
