Purpose of use calculating soffit overhang to maximize passive solar house design bug report the time portion is confusing as when i enter 12.
Solar panel angle calculator australia.
The ideal angle for solar panels in australia is usually equal to the latitude angle of the location of the property.
Use one of these formulas to find the best angle from the horizontal at which the panel should be tilted.
Hsa horizontal shadow angle.
If your latitude is below 25 use the latitude times 0 87.
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.
The graphic below shows.
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.
This is really important because it will allow any rain to run off the modules.
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 between 25 and 50 use the latitude times 0 76 plus 3 1 degrees.
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.
We ve got your covered our calculator factors in all of these variables before displaying your solar results.
The calculator will then show the optimum angle for the solar panel.
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.
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.
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.
Vsa vertical shadow angle.
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.
On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
The calculator shows the degrees from vertical.
Optimum angle for solar panels.
If your roof is totally flat then i strongly recommend mounting the solar panels at an angle of at least 10.
Also the time zones are not explained and one would think could be automatically.
