A solar panel generates its highest power output when the sun's rays are incident at a 90-degree angle to the module's surface. This condition, known as a normal angle of incidence, ensures that the maximum density of solar radiation flux is absorbed by the panel's active area.
The 30-degree rule is flexible: While 30 degrees is often cited as optimal, any roof pitch between 15-45 degrees will deliver excellent solar performance, typically within 5-10% of peak efficiency. Don't let imperfect pitch discourage you from going solar.
A thorough understanding of the orientation and tilt angles of the solar panel in relation to the sun radiation it receives is essential for optimizing the design of any PV system for best performance.
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.
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.
