The optimal solar panel tilt angle equals your latitude, facing true south (Northern Hemisphere) or true north (Southern Hemisphere). At 40° latitude (New York), set panels to 40° tilt.
Low tilt prevents wind load, but may collect more dirt. Balanced year-round performance. Optimized for strong summer production. Seasonal adjustment is highly beneficial.
Find the best tilt angle for your solar panels by location for optimal year-round, summer, and winter performance. Includes interactive visualizer and advanced options.
Department of Energy (DOE), the best direction and angle for solar panels is south-facing with a 15 to 40° tilt. The sun's rays strike your panels at different angles throughout the day and year.
