Rear shading factor

Webb2.1 Shading Factor The Shading Factor (F S) due to the presence of external shading devices as overhangs or side fins, can be defined as the ratio of the global solar radiation (direct, diffuse, reflected) received on the window in presence of shading devices to the global solar radiation which would be received on the window without them. WebbNear shadings: shading factor "Near shadings" definition: the obstacles draw visible shades on the array Definition of the Shading Factor : Ratio of the Shaded area to the total sensitive area (for a given sun's position) Acts on the beam component PVsyst creates a Table of shading factors for any direction of the space
