What if you have a flat roof.
Solar panel angle melbourne australia.
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.
I would be grateful for any thoughts suggestions on the direction to face solar panels.
If your latitude is above 50 see other situationsbelow.
If your roof is totally flat then i strongly recommend mounting the solar panels at an angle of at least 10.
This is really important because it will allow any rain to run off the modules.
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.
We are considering to install solar panels on the north and south facing side of the roof.
On a flat roof the tilt is 0 whereas if the angles were to be facing a wall it would be 90.
In australia common roof pitches are 15 or 22 5 so your modules will most likely be mounted at one of those angles.
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.
Use one of these formulas to find the best angle from the horizontal at which the panel should be tilted.
To get the best out of your photovoltaic panels you need to angle them towards the sun.
Sydney latitude 34º.
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.
For australia solar power yields are higher when panels face north.
The tilt involves primarily the angle that the panels are facing up into the sky.
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.
Melbourne latitude 38º.
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.
Perth latitude 32º.
As soon as a panel is tilted below 5.
If your latitude is between 25 and 50 use the latitude times 0 76 plus 3 1 degrees.
In fact all southern hemisphere locations should ideally position panels in a northerly direction.
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.
If your latitude is below 25 use the latitude times 0 87.
This solar angle calculator tells you the optimum angle to get the best out of your system.
Blantyre is at 15 degrees south almost at the same latitude than darwin in australia.
