Formula for calculating the spacing between photovoltaic panels

Estimate the ideal spacing between rows of solar panels to minimize shading and maximize efficiency based on latitude, tilt, and panel height. Formula: Spacing = Height / tan (Solar Altitude). The. . When designing a PV system that is tilted or ground mounted, determining the appropriate spacing between each row can be troublesome or a downright migraine in the making. This can. . For this purpose, the distances of the rows from each other are determined using the calculations for the angle of incidence of solar radiation for December 23, when the sun is lowest above the horizon. Winter Solstice Sun Angle – Since the sun is at its lowest elevation, panels cast their longest shadows.
