Solar panels should face directly into the sun to optimize their output.
Azimuth angle of a solar panel efficiency.
Positive 90 degrees is facing due west negative 90 degrees is facing due east.
What angle should i tilt my solar panels.
The compass angle shows 180 for south 90 for east and 270 for west.
Whether you are installing a solar panel on a flat roof or a pitched roof the output of the solar pv system would be increased by optimizing the tilt angle.
In most of the solar pv energy calculator tools an azimuth value of zero is facing the equator in both northern and southern hemispheres.
The tilt angle or elevation angle describes the vertical angle of your solar panels.
It is probably close to 90º at sunrise and 90º at sunset depending on the season.
This is the angle between the line that points to the sun and south.
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.
If your latitude is between 25 and 50 then the best tilt angle for summer is the latitude times 0 93 minus 21 degrees.
Azimuth angle is their horizontal facing in relation to the equator.
The following table gives the best dates on which to adjust.
Angles to the east are negative.
Orientation of the panels.
Azimuth is the array s east west orientation in degrees.
For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49.
The azimuth is the angle of easy west south and north.
Angles to the west are positive.
On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
If you are going to adjust the tilt of your solar panels twice a year and you want to get the most energy over the whole year then this section is for you.
The summer optimum tilt angle on the other hand will be 34 15 19.
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 array s tilt is the angle in degrees from horizontal.
This angle is only measured in the horizontal.
Solar azimuth angle γ s.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
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.
This angle is 0º at solar noon.
The general rule of thumb is that panels angled at the latitude angle plus 15 is best to maximise winter sun exposure.
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.
Tilt azimuth angle.
The ideal angle for your solar panels can vary depending on your solar objectives.
For the best results solar panels should be oriented towards the south.
