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). Start by entering your location in the search box. Winter Solstice Sun Angle – Since the sun is at its lowest elevation, panels cast their longest shadows. Tilt Angle – The more your panels tilt, the higher the. . For example, if you live in Denver at 40 degrees north latitude, set your panels at 40 degrees year-round, or adjust to 25 degrees in summer and 55 degrees in winter for maximum seasonal performance. The difference between optimal and poor tilt angles can mean losing hundreds of dollars in. . Most homeowners should choose the Year-Round angle. Choose Winter only if you are off-grid and need to maximize charging during short days. This table gives some examples for different latitudes.
