Optimum Tilt Angle For Solar Panels Sydney

To lean toward more production in the summer tilt your panels at your latitude minus 10 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. The orientation of the panels and the angle they are tilted will have a greater effect on annual energy production. However the panels can be installed anywhere between 10 to 35 deg with negligible efficiency loss. Both of these angles require latitude degrees.

Most australian homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation. In australia common roof pitches are 15 or 22 5 so your modules will most likely be mounted at one of those angles. Similarly you can calculate the angle for winter by adding 15. To lean toward more production in the winter tilt your panels at your latitude plus 10 15.

Sydney latitude 34º. Perth latitude 32º. In every capital except darwin output is maximized when the solar panel tilt is at least a few degrees less than the latitude. 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.

There are two methods for calculating the tilt angle for solar panels.
