Best Azimuth For Solar Panels

Both of these angles require latitude degrees.

Best azimuth for solar panels.

But that of course isn t always possible and further with today s improved panels a roof facing east southeast southwest or west also work very well. 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 tilt is included angle of horizon and solar panel. If you live in the southern hemisphere face them north.

In most of the solar pv energy calculator tools an azimuth value of zero is facing the equator in both northern and southern hemispheres. For best results your solar panels should face toward the equator. 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.

In solar terminology we d say the best compass azimuth or bearing is 180. The tilt is 0 if solar panel parallel to horizon to design the tilt is 90 if the solar panel is vertical to design. Positive 90 degrees is facing due west negative 90 degrees is facing due east. Optimal azimuth angle for solar panels.

Azimuth is the array s east west orientation in degrees. The compass angle shows 180 for south 90 for east and 270 for west. The decision of azimuth. For example the azimuth is 90 if solar is in the due east it is 90 if solar is in due west.

Whatever your latitude is you can subtract 15 from it to calculate the angle for summer. If you live in the northern hemisphere face them south. Similarly you can calculate the angle for winter by adding 15.
