Use this tool to plan your solar layout precisely and enjoy the benefits of well-optimized panel spacing, including higher energy yields, better system longevity, and improved return on investment for your solar project. . Contours refer to the lines that connect points of equal elevation on a topographic map. These lines illustrate the shape and slope of the land, providing critical information about how water will flow and how sunlight will reach different areas throughout the day. Tilt Angle – The more your panels tilt, the higher the. . A solar design layout defines how panels are positioned on a roof or ground system to maximize energy production and long-term performance. Formula: Spacing = Height / tan (Solar Altitude). The red line shows how much you would get by adjusting the tilt four times a year as described below.
