If your roof pitch is not exactly 27 5 do not despair the panel angle is not typically a decisive factor.
Best angle for solar panels brisbane.
Blantyre is at 15 degrees south almost at the same latitude than darwin in australia.
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.
Why is the perfect solar panel angle simply your latitude.
In brisbane the perfect solar panel tilt angle is 27 4.
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.
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.
For brisbane this means that a solar panel angle of 27 5 is optimal.
There is no shading from either side.
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.
We are considering to install solar panels on the north and south facing side of the roof.
The ideal angle for solar panels in australia is usually equal to the latitude angle of the location of the property.
The slope of your roof is usually the best angle at which to install your solar panels.
The ideal angle for your solar panels to maximize the power produced over the whole year is simply the latitude of your location.
Solar panel tilt angle in brisbane.
A new university of queensland study has declared the perfect angle and orientation for solar panels in brisbane that will provide optimum power generation.
The roof is tilted at about 15 degrees.
On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
If you have a flat roof your chosen solar company will fit tilt frames to ensure that your solar panels are at the ideal angle for maximum energy production.
So for my house in adelaide the ideal solar panel angle is 35 from horizontal.
Luckily it is actually dead simple.
