![]() ![]() I have drawn a picture - attached below of how I understand the question. BTW, there's a great formula for such a need. I think what you are after is called Insolation. ![]() Sunlight - Wikipedia, the free encyclopedia At any given moment, the amount of Solar radiation received at a location on the Earth's surface depends on the state of the atmosphere and the location's latitude. Hence the average incoming solar radiation (sometimes called the solar irradiance), taking into account the angle at which the rays strike and that at any one moment half the planet does not receive any solar radiation, is one-fourth the solar constant (approximately 342 W/m²). RE²), but as it rotates this energy is distributed across the entire surface area (4.The Earth receives a total amount of radiation determined by its cross section (π The approximate average value cited, 1366 W/m², is equivalent to 1.96 calories per minute per square centimeter, or 1.96 langleys (Ly) per minute. ![]() The solar constant does not remain constant over long periods of time (see Solar variation). Thus, for the whole Earth (which has a cross section of 127,400,000 km²), the power is 1.740×1017 W, plus or minus 3.5%. It is measured by satellite to be roughly 1366 watts per square meter (W/m²), though this fluctuates by about 6.9% during a year (from 1412 W/m² in early January to 1321 W/m² in early July) due to the earth's varying distance from the Sun, and typically by much less than one part per thousand from day to day. The solar constant includes all types of solar radiation, not just the visible light. The solar constant is the amount of incoming solar electromagnetic radiation per unit area, measured on the outer surface of Earth's atmosphere in a plane perpendicular to the rays. ![]()
