The suggested tilt angle for photovoltaic solar panels is generally equal to the latitude of the installation site. Adjusting the angle seasonally—steeper in winter and flatter in summer—can further optimize
Simple is the basic idea of controlling solar panel efficiency: panels generate the maximum power when sunlight strikes their surface perpendicularly, therefore forming a direct 90
Scroll to the top of this page to use our Solar Panel Tilt Angle Calculator. Simply enter your address and it will provide the optimal angles for each season, as well as a year-round average angle for your
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 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
Across the continental U.S., the optimal tilt can range from 30-45 degrees. However, the further north you live, the more orientation can affect solar panel efficiency. For example,
Tilting the modules to a certain degree according to the seasons can improve the solar array''s performance and generate more power.
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
