Correct Angle For Solar Panels

For instance if your latitude.

Correct angle for solar panels.

The summer optimum tilt angle on the other hand will be 34 15 19. 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. Overall the angle of your rooftop has less impact on solar panel performance than the direction your roof faces. Whatever your latitude is you can subtract 15 from it to calculate the angle for summer.

There are two methods for calculating the tilt angle for solar panels. Both of these angles require latitude degrees. For the best results solar panels should be oriented towards the south. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.

Find the best angle for optimizing solar collection during winter when solar energy is most scarce by multiplying your latitude by 0 89 and then adding 24 degrees. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49. The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer. Orientation of the 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. Ideally a fixed roof mounted solar energy system should be at an angle that is equal to the latitude of the location where it is installed.
