Positive 90 degrees is facing due west negative 90 degrees is facing due east.
Optimal solar panel azimuth.
Therefore the best angle for your solar panels is the one that allows the panels to get the most direct perpendicular light.
The azimuth is the angle of easy west south and north.
There are two methods for calculating the tilt angle for solar panels.
In most of the solar pv energy calculator tools an azimuth value of zero is facing the equator in both northern and southern hemispheres.
If you live in the northern hemisphere face them south.
In terms of solar pv system the due south of azimuth is 0 it is minus angle from south to east to north it is positive angle from south to west to north.
On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
Solar panels should always face true south if you are in the northern hemisphere or true north if you are in the southern hemisphere.
True north is not the same as magnetic north.
If you live in the southern hemisphere face them north.
The compass angle shows 180 for south 90 for east and 270 for west.
Optimal azimuth angle for solar panels for best results your solar panels should face toward the equator.
For example the azimuth is 90 if solar is in the due east it is 90 if solar is in due west.
The optimum tilt angle for an azimuth tracking was 19 closer to vertical than for a fixed south facing panel.
Azimuth is in the angle relative to map north where 0 is north 90 is west 180 is south and 270 is east.
Similarly you can calculate the angle for winter by adding 15.
The azimuth and tilt confirmation of solar panel is the one of important factors in the design of solar pv system.
Whatever your latitude is you can subtract 15 from it to calculate the angle for summer.
In the northern hemisphere between the latitudes of 23 and 90 the sun is always in the south.
Tilt is the vertical angle where a 0 tilt means that the panel is laying flat and a 90 tilt means that it s vertical.
Solar panels produce electricity when sunlight hits their surface and they produce the most energy when that sunlight is exactly perpendicular to the panel face.
Both of these angles require latitude degrees.
