Which direction should my roof face for solar panels.
Which way should solar panels face in uk.
It is at this location that your panels will receive the maximum sunlight throughout the day.
Solar south or geographic south.
During the early stages of your solar project these details are looked at and used to determine the way in which your solar panel system should be oriented and the direction that they should face.
In northern hemisphere most solar panels point south.
For the best results solar panels should be oriented towards the south.
If your roof does not face the right direction then surface mounted panels or pole mounted panels may be your best bet.
Five or six years ago the question of which direction solar panels should face was easy.
If even one panel is shaded it will reduce the output of all your panels unless you invest in micro inverters or other optimizing devices.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
Because high feed in tariffs were available they simply had to have an orientation facing north in order to maximise the amount of electricity they produced and so earn the most feed in.
Most solar panels are facing the wrong direction say scientists.
To correct the compass reading your solar installer will calculate the magnetic declination of your site.
The following is a guest post by dr.
Solar panel orientation and elevation.
South facing roof panels see the sun when it is at its most intense for the longest period of time which is why they generate the most energy.
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.
The direction solar panels should face is true south a k a.
The direction your panels face is certainly a factor in how much they will generate and closer to south is better but it is only one factor.
Which way should my solar panels be facing.
The most optimum direction to face your solar panels is somewhere between south and west.
Joshua rhodes a postdoctoral research fellow in the webber energy group and the energy institute at the university.
If your roof faces slightly off south or even straight east west it is still very likely that solar pv could generate savings and income for you.
But west facing panels are able to generate more even flow of electricity.
So what direction should solar panels face.
So we ve established that there s a sweet spot for your solar panel orientation which is directly south and a sweet spot for elevation which is between 30º and 40º.
