Best Tilt Angle For Solar Panels

The decision of azimuth.

Best tilt angle for solar panels.

For los angeles a solar panel tilt of 19 degrees works the best. Movable and adjustable solar panels. Both of these angles require latitude degrees. In boston a solar array at 30 degrees south is still going to produce more electricity than tilted at 42 degrees and facing north.

To lean toward more production in the winter tilt your panels at your latitude plus 10 15. The tilt is 0 if solar panel parallel to horizon to design the tilt is 90 if the solar panel is vertical to design. For instance in the san francisco bay area the best solar panel tilt angle is between 22 23 degrees. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49.

There are two methods for calculating the tilt angle for solar panels. If your latitude is between 25 and 50 then the best tilt angle for summer is the latitude times 0 93 minus 21 degrees. Similarly you can calculate the angle for winter by adding 15. To optimize overall production year round tilt your panels at your latitude.

If you are going to adjust the tilt of your solar panels twice a year and you want to get the most energy over the whole year then this section is for you. Whatever your latitude is you can subtract 15 from it to calculate the angle for summer. If you would like to get the absolute best performance from your solar panels you should put them up on movable scaffolding on the yard or on special movable panel holders or frames on your roof. To lean toward more production in the summer tilt your panels at your latitude minus 10 15.

The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer. This way you could adjust the tilt angle and direction of the solar panels to an optimal level. The best way to find a high quality solar installation is with energysage. Since solar panels are more productive when the sun s rays are perpendicular to their surfaces the certainly best orientation is the one directly true south azimuth angle 180.

For a precise method use the second formula on this page to calculate tilt angle. The tilt is included angle of horizon and solar panel. The following table gives the best dates on which to adjust.
