Solar Panel Angle Australia

The ideal angle for solar panels in australia is usually equal to the latitude angle of the location of the property.

Solar panel angle australia.

The graphic below shows. Blantyre is at 15 degrees south almost at the same latitude than darwin in australia. This solar angle calculator tells you the optimum angle to get the best out of your system. The roof is tilted at about 15 degrees.

The angle of your solar array is an important factor in maximizing your energy production. 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. 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. Most solar arrays are installed at a tilt.

However the panels can be installed anywhere between 10 to 35 deg with negligible efficiency loss. To get the best out of your photovoltaic panels you need to angle them towards the sun. To optimize overall production year round tilt your panels at your latitude. To lean toward more production in the summer tilt your panels at your latitude minus 10 15.

On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north. Solar panel angle by zip code. It s a common belief that panel tilt from horizontal should equal a location s latitude but this is not quite correct. This is because it s based on the average position of the sun over your property.

We are considering to install solar panels on the north and south facing side of the roof. The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer. The summer optimum tilt angle on the other hand will be 34 15 19. 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.

Most australian homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation. There is no shading from either side. Optimum angle for solar panels. In 7 of australia s 8 capitals the best angle is at least 3 degrees less than the latitude.

The orientation of the panels and the angle they are tilted will have a greater effect on annual energy production. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49. 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.
