This is because the sun is always in the southern half of the sky in the northern hemisphere.
Correct solar panel orientation.
True south can also be calculated at noon when shadows from vertical objects run north south.
Orientation of the panels.
Solar south or geographic south.
The vertical tilt of the solar panel is termed as a tilt angle.
To correct the compass reading your solar installer will calculate the magnetic declination of your site.
For the best results solar panels should be oriented towards the south.
On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
In the northern hemisphere the general rule for solar panel placement is solar panels should face true.
They need maximum exposure to the sun.
Regardless of the orientation experts note that it is more efficient to have a consecutive block of solar panels installed using the same orientation either vertical or horizontal.
The angle that a solar panel should be set.
Fixed tilt solar.
The reason behind that is pretty simple.
The sun moves throughout the day and its position angle also changes with the seasons.
The direction solar panels should face is true south a k a.
The angle or tilt of a solar panel is also an important consideration.
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.
