Correct Angle For Solar Panels

The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer.

Correct angle for solar panels. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north. The summer optimum tilt angle on the other hand will be 34 15 19. 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. There are two methods for calculating the tilt angle for solar panels.

However pitch angles between 30 and 45 degrees will work well in most situations. Orientation of the panels. This is because the sun is always in the southern half of the sky in the northern hemisphere. Whatever your latitude is you can subtract 15 from it to calculate the angle for summer.

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. Both of these angles require latitude degrees. Similarly you can calculate the angle for winter by adding 15.

For instance if your latitude. 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.
