Best Angle To Tilt Solar Panel

The more exact way to count out the best tilt angle is done as follows.

Best angle to tilt solar panel. If you are able to adjust the angle of your solar panels a few times per year here is the adjustment schedule we recommend. For instance in the san francisco bay area the best solar panel tilt angle is between 22 23 degrees. For a latitude up to 25 take your latitude and multiply it by 0 87 for a latitude between 25 to 50 take your latitude multiply by 0 87 after that you will add 3 1 degrees for a latitude over 50 the most ideal angle will end up being approximately 45 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.

Tilt the panels to your latitude plus 15. Tilt the panels to your latitude minus 15. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49. Tilt the panels to your latitude.

Both the slope and the orientation is critical for best meeting your needs. Whatever your latitude is you can subtract 15 from it to calculate the angle for summer. Similarly you can calculate the angle for winter by adding 15. There are two methods for calculating the tilt angle for solar panels.

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. It s not a good idea to install your panels to face a suboptimal direction even if it means the best tilt possible. The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer.

Tilt the panels to your latitude. For los angeles a solar panel tilt of 19 degrees works the best. But the best roof angle for solar panels has less of an impact on all of this productivity than the direction orientation in which your solar energy system faces.
