Similarly you can calculate the angle for winter by adding 15.
Optimum tilt angle for solar panels sydney.
Generally speaking unless your roof is flat the pitch of your home s roof is going to be the angle your solar panels are mounted at.
Perth latitude 32º.
Both of these angles require latitude degrees.
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.
To optimize overall production year round tilt your panels at your latitude.
There are two methods for calculating the tilt angle for solar panels.
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.
However the panels can be installed anywhere between 10 to 35 deg with negligible efficiency loss.
In every capital except darwin output is maximized when the solar panel tilt is at least a few degrees less than the latitude.
Whatever your latitude is you can subtract 15 from it to calculate the angle for summer.
In australia common roof pitches are 15 or 22 5 so your modules will most likely be mounted at one of those angles.
To lean toward more production in the winter tilt your panels at your latitude plus 10 15.
The orientation of the panels and the angle they are tilted will have a greater effect on annual energy production.
