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). . When installing solar panel systems, it is crucial not only to consider the spacing between panels and installation angles but also to comply with local government and regulatory requirements concerning the distance between solar panels and property boundaries. Winter Solstice Sun Angle – Since the sun is at its lowest elevation, panels cast their longest shadows. Shadows are bad; even small ones can lower energy production.
