The tilt is included angle of horizon and solar panel.
Best azimuth for solar panels.
In solar terminology we d say the best compass azimuth or bearing is 180.
The compass angle shows 180 for south 90 for east and 270 for west.
If you live in the northern hemisphere face them south.
If you live in the southern hemisphere face them north.
This being the case the general best practice to date has always been to position solar panels facing south in order to capture the maximum amount of sunlight overall.
Positive 90 degrees is facing due west negative 90 degrees is facing due east.
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.
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.
The decision of azimuth.
Azimuth is the array s east west orientation in degrees.
For best results your solar panels should face toward the equator.
The azimuth has decided the incidence direction of sunlight decided the lighting conditions of solar from various different orientation hillsides or buildings.
Similarly you can calculate the angle for winter by adding 15.
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.
The tilt is 0 if solar panel parallel to horizon to design the tilt is 90 if the solar panel is vertical to design.
Optimal azimuth angle for solar panels.
Both of these angles require latitude degrees.
