WebDec 19, 2024 · The POWERsolar values are the downward solar radiation reaching the earth's surface for all-sky conditions. The influence of clouds has been taken into account in computing the solar values. The POWERdata does not provide the net radiation defined as difference between the incoming and outgoing radiation. WebThe direct insolation from the sun map sector ( Dirθ,α) with a centroid at zenith angle ( θ) and azimuth angle ( α) is calculated using the following equation: Dir θ,α = S Const * β m (θ) * SunDur θ,α * SunGap θ,α * cos (AngIn θ,α) ( 2 ) where: SConst — The solar flux outside the atmosphere at the mean earth-sun distance, known ...
