The optimal tilt angle is calculated by adding 15 degrees to your latitude in winter and subtracting 15 degrees from your latitude in summer. For example, if your latitude is 34°, the optimal tilt angle for
The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter, and subtracting 15 degrees from your latitude during summer. For instance, if your latitude is 34°, the optimum tilt
This tool estimates the optimal tilt (angle) for a fixed‐mount solar panel based on your latitude. Adjusting your panels to the right angle can increase yearly energy yield by up to 20 %.
The next question is, at what angle from horizontal should the panels be tilted? Books and articles on solar energy often give the advice that the tilt should be equal to your latitude, plus 15
Compared to flat panels, panels tilted at 35 degrees had 19% more energy output, so tilting had an even more positive effect than for Phoenix. Also the maximum point is further away
The side-view diagram shows your panel at different tilt angles, with summer and winter sun paths arcing overhead. Drag the slider to experiment with different angles and watch the efficiency
For a fixed system (95% of residential installs), the Golden Rule is to tilt your panels at an angle equal to your Latitude. This averages out the sun''s position over 365 days.
Discover the best angle for your solar panels with our Solar Panel Tilt Angle Calculator. Maximize energy efficiency and save money!
Comparisons between a shallow pitched roof at a 15° angle and a steep 45° angle result in little solar production difference. The amount of power generated evens itself out across the seasons.
Calculate optimal tilt angle for your solar panels based on latitude for year-round, summer, and winter performance. Formulas: Year-round tilt = latitude; Summer tilt = latitude - adjustment; Winter tilt =
