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.
Solar panel tilt angle australia.
If your latitude is between 25 and 50 then the best tilt angle for summer is the latitude times 0 93 minus 21 degrees.
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.
However the panels can be installed anywhere between 10 to 35 deg with negligible efficiency loss.
The graphic below shows.
If you are looking to install a typical solar power system on a normal sloped roof this information may not be much use to you.
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.
You have a couple options here.
The orientation of the panels and the angle they are tilted will have a greater effect on annual energy production.
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.
If you are going to adjust the tilt of your solar panels twice a year and you want to get the most energy over the whole year then this section is for you.
On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
Finding the optimal tilt for your solar panels.
The ideal angle for solar panels in australia is usually equal to the latitude angle of the location of the property.
Pick one angle and leave it alone or adjust the tilt a few times per year to optimize seasonal production.
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.
It s a common belief that panel tilt from horizontal should equal a location s latitude but this is not quite correct.
The following table gives the best dates on which to adjust.
In australia common roof pitches are 15 or 22 5 so your modules will most likely be mounted at one of those angles.
The tilt angle can be quite important in power production and generally we recommend that a solar panel array at 32 degrees latitude sydney be angled between 15 and 30 degrees facing north of course.
Optimum angle for solar panels.
The tilt involves primarily the angle that the panels are facing up into the sky.
The other half of the equation is finding the vertical angle or tilt of your solar panels.
In 7 of australia s 8 capitals the best angle is at least 3 degrees less than the latitude.
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.
Most australian homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation.
