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.
Orient panels towards the sun: south in the Northern Hemisphere, north in the Southern Hemisphere, with east and west also viable. Some companies use solar trackers to boost efficiency by.
Optimal Tilt Strategy: The most effective approach is setting tilt angles to latitude minus 15° in summer and latitude plus 15° in winter, with quarterly adjustments providing the best balance between performance gains and maintenance effort.
Low tilt prevents wind load, but may collect more dirt. Balanced year-round performance. Optimized for strong summer production. Seasonal adjustment is highly beneficial.

Ideally, your solar panels will be installed on a south-facing roof at an angle of about 30°. These are the optimal conditions for solar panel production.
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.
