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). Winter Solstice Sun Angle – Since the sun is at its lowest elevation, panels cast their longest shadows. Panel Orientation: To maximize solar radiation, the orientation of the panels is. . In our original article "Determining Module Inter-Row Spacing," we examined how optimal inter-row spacing in photovoltaic (PV) systems is critical for maximizing energy production, ensuring compliance with building codes, and optimizing economic returns. Correct spacing improves energy use and makes panels last. . If your system consists of two or more rows of PV panels, you must make sure that each row of panels does not shade the row behind it.
