Proper Solar Panel Angle

Here two simple methods for calculating approximate solar panel angle according to your latitude.

Proper solar panel angle.

Both of these angles require latitude degrees. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north. There are two methods for calculating the tilt 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. 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. Whatever your latitude is you can subtract 15 from it to calculate the angle for summer. 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.
