Optimal Angle For Solar Panels In San Diego

For a latitude between 25 to 50 take your latitude multiply by 0 87 after that you will add 3 1 degrees.

Optimal angle for solar panels in san diego. Orientation of the panels. For example if the location of the solar array is at 50 o latitude the optimal tilt angle is also 50 o. Latitude in san diego. The next question is at what angle from horizontal should the panels be tilted.

The summer optimum tilt angle on the other hand will be 34 15 19. Latitude in los angeles. This is because the sun is always in the southern half of the sky in the northern hemisphere. 32 42 117 10.

It turns out that you can do better than this about 4 better. While the angle of your solar panels is important a more important factor in your energy production is going to be the direction your panels face. The question is at what angle from horizontal should the panels be tilted. For the best results solar panels should be oriented towards the south.

Books and articles on solar energy often give the advice that the tilt should be equal to your latitude plus 15 degrees in winter or minus 15 degrees in summer. As a general rule of thumb keep in mind that the panels need to be more vertical during winter to face the lower sun directly and more tilted towards the ground during summer to face the higher sun. However if the panels are turned at an angle greater than 45 compared to true south production begins to decrease significantly. The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer.

Essentially the closer a solar panel is located to the equator the more the panel should be pointing straight up. At 90 from true south therefore east and west production can drop to 30. Latitude in san francisco. For a latitude up to 25 take your latitude and multiply it by 0 87.

A general rule for optimal annual energy production is to set the solar panel tilt angle equal to the geographical latitude. In order to figure out what the best angle to tilt your solar panels you must first figure out your latitude. It just depends on where you live. Books and articles on solar energy often give the advice that the tilt should be equal to your latitude plus 15 degrees in winter or minus 15 degrees in summer.
