The most optimum direction to face your solar panels is somewhere between south and west.
Which direction should fixed solar panels face in australia.
For example in brisbane if your panels are facing west 270 and are angled 20 from horizontal you will get 89 of the energy compared to the optimum orentation of north and 30.
So to help people decide what is the best direction to face their panels for all the australian capitals i ll describe.
Solar panels however need to face solar or geographic south which is the direction towards the south pole.
The direction solar panels should face is true south a k a.
Which direction should solar panels face.
Solar south or geographic south.
To correct the compass reading your solar installer will calculate the magnetic declination of your site.
It s determined by the shape of their roof.
In fact all southern hemisphere locations should ideally position panels in a northerly direction.
The direction solar panels should ideally face for optimum sun exposure varies depending on location.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
By the same reasoning if the solar panel is located in the southern hemisphere the panel should instead face in the direction of true north.
Of course most people don t get to decide which direction they face their solar panels.
True south can also be calculated at noon when shadows from vertical objects run north south.
It is at this location that your panels will receive the maximum sunlight throughout the day.
The direction that your solar panels face is ultimately dependent on whether or not your system is connected through net energy metering nem and under a time of use tou payment structure.
If your property is located in the northern hemisphere panels facing.
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.
This table shows you how much energy you can expect to get from almost any combination of solar panel direction and angle in the capital cities compared to the optimum orientation.
The direction in which panels will generate over 99 9 of maximum possible output.
Once again referring to the graph.
Since the majority of solar panel owners keep their system on the grid we can split this grouping into simply those who pay for energy based on a tou payment.
Australia being in the southern hemisphere experiences a sun that is predominantly coming at us from the north.
There is of course deviance throughout the seasons but ideally solar panels should be facing as close to true north as possible to reduce the impact that the winter seasons have on energy yields.
Net energy metering and time of use.
For australia solar power yields are higher when panels face north.
