For brisbane this means that a solar panel angle of 27 5 is optimal.
Best angle for solar panels brisbane.
Solar panel tilt angle in brisbane.
For example if you reside in sydney a roof pitch of 34 would be considered ideal as this is equal to the latitude angle 33 86 of the nsw capital.
It is best to position your panels at the same angle as the latitude of the location to maximise year round solar production.
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.
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.
In brisbane the perfect solar panel tilt angle is 27 4.
Optimum angle for solar panels.
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.
This means that for best results the roof pitch of your property should ideally be equal to the latitude angle with the panels mounted at the same angle as the roof.
The roof is tilted at about 15 degrees.
Blantyre is at 15 degrees south almost at the same latitude than darwin in australia.
We are considering to install solar panels on the north and south facing side of the roof.
If your roof pitch is not exactly 27 5 do not despair the panel angle is not typically a decisive factor.
Luckily it is actually dead simple.
The ideal angle for solar panels in australia is usually equal to the latitude angle of the location of the property.
On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
Why is the perfect solar panel angle simply your latitude.
So for my house in adelaide the ideal solar panel angle is 35 from horizontal.
We have found brisbane panels should be angled at 26 degrees facing true north says uq global change institute researcher professor tapan kumar saha.
The slope of your roof is usually the best angle at which to install your solar panels.
There is no shading from either side.
