Best Solar Panel Angle All Around

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.

Best solar panel angle all around.

There are two methods for calculating the tilt 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. For the best results solar panels should be oriented towards the south. Latitude x 0 9 23 5 degrees.

At some places as much as a vertical tilt of the panels is needed to get the maximum output during wintertime. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49. True south or the geographic south will yield the best results overall. Latitude 2 5 degrees.

For houses situated at 25 30 add 5 to local latitude for 30 35 add 10 to local latitude for 35 40 add 15 to local latitude and for houses situated at more than 40 add 20 to local latitude 1. In general a steeper slope is preferable during the summer as the sun will be higher in the sky. Similarly you can calculate the angle for winter by adding 15. Ideally you want your solar system to be on the area of your roof that faces south specifically southwest.

The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer. The answers you end up with are the best angles for each particular season. During winter the sun is lower and to catch more of its light the best solar panel angle would be more tilted. Latitude x 0 9 29 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. Both of these angles require latitude degrees. This is because the sun is always in the southern half of the sky in the northern hemisphere. What s the best angle for solar panels.

The summer optimum tilt angle on the other hand will be 34 15 19. Whatever your latitude is you can subtract 15 from it to calculate the angle for summer. Once you have figured this out you can use one of the formulas below to calculate the best angle for your solar panels for each season.
