[pdf] Free solar panel spacing calculator to determine optimal row distance based on latitude, tilt, panel height, and season. Reduce shading losses and maximize rooftop or ground-mounted solar efficiency. Winter Solstice Sun Angle – Since the sun is at its lowest elevation, panels cast their longest shadows. Uses your device location (permission prompt). Auto-estimated from longitude (no DST). Typical “worst case” is winter solstice (~Dec 21). Uses trigonometric analysis of sun elevation angles on winter solstice (December 21st) to determine shadow length based on panel dimensions, tilt angle, and location. . 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.
