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.
Solar panel angle melbourne australia.
We are considering to install solar panels on the north and south facing side of the roof.
For australia solar power yields are higher when panels face north.
We are looking at installing a 5kw system lg neon 2 panels and fornius inverter on a double storey house and had initially thought of splitting the panels between our north east and west facing roofs so that we got production over most of the day 8 panels north 4 east and 4 west.
Use one of these formulas to find the best angle from the horizontal at which the panel should be tilted.
The roof is tilted at about 15 degrees.
Ideally solar panels would be positioned at an angle of 38 in melbourne equal to the latitude angle of the city 37 81.
This is really important because it will allow any rain to run off the modules.
If your latitude is below 25 use the latitude times 0 87.
I would be grateful for any thoughts suggestions on the direction to face solar panels.
The geoscience australia website www ga gov au allows you to find the latitude of more than 250 000 place names in australia and calculate the sun angle at any time of the day on any day of the year.
As indicated in the above diagram an angle of approximately 32 is the best but anywhere between 20 and 40 is optimal for around a 90 efficiency.
Optimal tilt 31º in every capital except darwin output is maximized when the solar panel tilt is at least a few degrees less than the latitude.
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.
Melbourne latitude 38º.
If your latitude is between 25 and 50 use the latitude times 0 76 plus 3 1 degrees.
In australia common roof pitches are 15 or 22 5 so your modules will most likely be mounted at one of those angles.
If your latitude is above 50 see other situationsbelow.
Blantyre is at 15 degrees south almost at the same latitude than darwin in australia.
If your roof is totally flat then i strongly recommend mounting the solar panels at an angle of at least 10.
Perth latitude 32º.
What if you have a flat roof.
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.
The direction solar panels should ideally face for optimum sun exposure varies depending on location.
Sydney latitude 34º.
In fact all southern hemisphere locations should ideally position panels in a northerly direction.
Solar output losses when the panel angle is not ideal.
On a flat roof the tilt is 0 whereas if the angles were to be facing a wall it would be 90.
