What if you have a flat roof.
Solar panel angle calculator australia.
If you cannot change the angle of your panel throughout the year angle your panel according to the time of year that you need to get the best performance out of your system.
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.
We ve got your covered our calculator factors in all of these variables before displaying your solar results.
If your latitude is between 25 and 50 use the latitude times 0 76 plus 3 1 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.
If your latitude is below 25 use the latitude times 0 87.
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.
The calculator will then show the optimum angle for the solar panel.
Use one of these formulas to find the best angle from the horizontal at which the panel should be tilted.
Melbourne 11 e adelaide 8 e perth 4 w in the report generated the altitude is the angular measurement of the sun and the azimuth angle is its angle taken from true north clockwise.
This is really important because it will allow any rain to run off the modules.
On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
Vsa vertical shadow angle.
Also the time zones are not explained and one would think could be automatically.
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.
Enter magnetic declination click here for chart i e.
The ideal angle for solar panels in australia is usually equal to the latitude angle of the location of the property.
These include the australian government solar rebate any state rebates your feed in tariff the cost of your solar panels and the rate that you pay for your electricity.
The calculator shows the degrees from vertical.
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.
The graphic below shows.
Hsa horizontal shadow angle.
Which should be noon if you are using a 24 hour time the sun angle is shown as negative and i have to go to around 10 pm 2200 hours to get the highest elevation angle.
