Most roof pitches (15-45°) work well for solar panels. While it may not be the absolute optimal angle, the difference is usually minimal (2-8% energy loss), and roof mounting is often more cost-effective than ground mounting at custom angles.

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.
The optimal solar panel tilt angle equals your latitude for year-round efficiency. This simple adjustment can increase solar output by 10 to 25 percent depending on your.
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.
