If don t have a north facing roof or your roof is flat then your solar installer may install brackets to help angle the panels correctly.
Best angle for solar panels adelaide.
However depending on when you use the most electricity you may want to consider optimising your installation for different times in the year.
The optimum angle varies throughout the year depending on the seasons and your location and this calculator shows the difference in sun height on a month by month.
This does however cost slightly more.
No tracking solar panels.
Optimum angle for solar panels.
This maximizes the amount of energy striking the panels and being produced.
If your roof is shaded by trees consider if it s worth having them pruned.
This solar angle calculator tells you the optimum angle to get the best out of your system.
If you face the panels east your panels will generate less energy over the course of the day than if they were facing north but if you use more electricity during the morning hours this might make sense for you.
If your latitude is outside this range see other situationsbelow.
Luckily it is actually dead simple.
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 following table gives the best dates on which to adjust.
Additionally solar panels should ideally be installed facing north to maximise solar output.
Why is the perfect solar panel angle simply your latitude.
If your latitude is between 25 and 50 then the best tilt angle for summer is the latitude times 0 93 minus 21 degrees.
The two factors that such an angle is controlled by are the orientation north south east west and the angle of the panels from the surface of the earth.
So for my house in adelaide the ideal solar panel angle is 35 from horizontal.
Essentially the closer a solar panel is located to the equator the more the panel should be pointing straight up.
Equator facing is usually the best orientation for fixed array i e.
A general rule for optimal annual energy production is to set the solar panel tilt angle equal to the geographical latitude.
This allows for the most total production throughout the year.
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.
The optimal panel angle in adelaide for year round solar production is 35 from the horizontal and facing due north 0 azimuth.
The best tilt angle for winter is the latitude times 0 875 plus 19 2 degrees.
The ideal situation is when the sun is hitting the panels at a perfectly perpendicular angle 90.
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.
The ideal angle for your solar panels to maximize the power produced over the whole year is simply the latitude of your location.
For example if the location of the solar array is at 50 o latitude the optimal tilt angle is also 50 o.
