The graphic below shows.
Solar panel angle calculator australia.
The calculator shows the degrees from vertical.
Purpose of use calculating soffit overhang to maximize passive solar house design bug report the time portion is confusing as when i enter 12.
We ve got your covered our calculator factors in all of these variables before displaying your solar results.
Vsa vertical shadow angle.
What if you have a flat roof.
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.
The ideal angle for solar panels in australia is usually equal to the latitude angle of the location of the property.
Enter magnetic declination click here for chart i e.
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.
Optimum angle for solar panels.
In australia common roof pitches are 15 or 22 5 so your modules will most likely be mounted at one of those angles.
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 your latitude is below 25 use the latitude times 0 87.
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 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.
If your latitude is above 50 see other situationsbelow.
If your latitude is between 25 and 50 use the latitude times 0 76 plus 3 1 degrees.
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.
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.
Also the time zones are not explained and one would think could be automatically.
The calculator will then show the optimum angle for the solar panel.
Hsa horizontal shadow angle.
