This article is about the best angle to tilt solar panels for the maximum possible energy yield over a year.
Best angle for solar panels perth.
This maximizes the amount of energy striking the panels and being produced.
On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
It s a common belief that panel tilt from horizontal should equal a location s latitude but this is not quite correct.
For the best results solar panels should be oriented towards the south.
As we have mentioned before in the southern hemisphere due north is usually the best orientation for panels.
In 7 of australia s 8 capitals the best angle is at least 3 degrees less than the latitude.
Luckily it is actually dead simple.
Welcome to another entry in our ongoing solar 101 series.
Today we re going to explain how to mount your solar panels to get the most energy from them.
Optimum angle for solar panels.
The vertical tilt of your panels.
Let s start with two key terms.
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.
If you can position your solar panels on an angle of 32 you will maximise your system s potential to generate solar energy.
The ideal angle for solar panels in australia is usually equal to the latitude angle of the location of the property.
The ideal situation is when the sun is hitting the panels at a perfectly perpendicular angle 90.
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.
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.
Elevation angle and azimuth angle commonly shortened to angle and azimuth for brevity.
If your roof is flat you will need to mount your panels on at least 10 pitch so that they clean themselves.
Best angle for solar panels in perth.
Why is the perfect solar panel angle simply your latitude.
This solar angle calculator tells you the optimum angle to get the best out of your system.
To get the best out of your photovoltaic panels you need to angle them towards the sun.
While the angle of your solar panels is important a more important factor in your energy production is going to be the direction your panels face.
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.
So for my house in adelaide the ideal solar panel angle is 35 from horizontal.
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.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
