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.
Best angle for solar panels sydney.
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.
This solar angle calculator tells you the optimum angle to get the best out of your system.
It s a common belief that panel tilt from horizontal should equal a location s latitude but this is not quite correct.
Therefore the best angle for your solar panels is the one that allows the panels to get the most direct perpendicular light.
This maximizes the amount of energy striking the panels and being produced.
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.
Ideally you want your solar system to be on the area of your roof that faces south specifically southwest.
What s the best angle for solar panels.
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.
That s because you ll get way more sunlight hitting the roof thereby converting into way more energy.
The best angle to install solar panels is the angle your roof is already at.
While it is possible to use frames that alter the tilt of the panels unless there are special circumstances these are not worth it these days as it is generally cheaper and easier to just install extra 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.
True south or the geographic south will yield the best results overall.
But in the far north the difference is not so great and in townsville south facing solar panels will only produce around 17 less electricity in total than north facing ones.
In 7 of australia s 8 capitals the best angle is at least 3 degrees less than the latitude.
The ideal angle for solar panels in australia is usually equal to the latitude angle of the location of the property.
In sydney south facing solar panels will typically produce around 28 less energy than north facing panels and the steeper the roof the less electricity they will produce.
Optimum angle for solar panels.
While the sun is in a higher position in the sky during the summer and lower position during the winter it has an average position right in between the two seasons.
To get the best out of your photovoltaic panels you need to angle them towards the sun.
On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
In australia common roof pitches are 15 or 22 5 so your modules will most likely be mounted at one of those angles.
The ideal situation is when the sun is hitting the panels at a perfectly perpendicular angle 90.
