Optimum Tilt Angle For Solar Panels Sydney

In australia common roof pitches are 15 or 22 5 so your modules will most likely be mounted at one of those angles.

Optimum tilt angle for solar panels sydney.

Both of these angles require latitude degrees. 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. Whatever your latitude is you can subtract 15 from it to calculate the angle for summer.

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. Most australian homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation. There are two methods for calculating the tilt angle for solar panels.

Similarly you can calculate the angle for winter by adding 15. To optimize overall production year round tilt your panels at your latitude. Sydney latitude 34º. 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.

However the panels can be installed anywhere between 10 to 35 deg with negligible efficiency loss.
