Correct Angle For Solar Panels

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.

Correct angle for solar panels.

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. This is because the sun is always in the southern half of the sky in the northern hemisphere. For instance if your latitude. Both of these angles require latitude degrees.

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. The summer optimum tilt angle on the other hand will be 34 15 19. Similarly you can calculate the angle for winter by adding 15. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49.

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. Overall the angle of your rooftop has less impact on solar panel performance than the direction your roof faces. The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer. There are two methods for calculating the tilt angle for solar panels.

Orientation of the panels. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
