Optimal Tilt Angle For Solar Panels

A tilt of approximately 25 to 35 will work best for locations in the us.

Optimal tilt angle for solar panels.

It s not a good idea to install your panels to face a suboptimal direction even if it means the best tilt possible. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49. For instance in the san francisco bay area the best solar panel tilt angle is between 22 23 degrees. There are two methods for calculating the tilt angle for 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. For best results your solar panels should face toward the equator. The other half of the equation is finding the vertical.

Tilt azimuth angle. So what is the best tilt angle for solar panels in the united states. Similarly you can calculate the angle for winter by adding 15. Finding the optimal angle to mount your solar panels optimal azimuth angle for solar panels.

For fall or spring you can just subtract 2 5 from the latitude. 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 a precise method use the second formula on this page to calculate tilt angle. The summer optimum tilt angle on the other hand will be 34 15 19.

Lower tilts closer to 25 will be better for southern states while those in the north will want to be closer to 35.
