Solar Panel Angle Australia

To optimize overall production year round tilt your panels at your latitude.

Solar panel angle australia.

Most australian homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation. This solar angle calculator tells you the optimum angle to get the best out of your system. However the panels can be installed anywhere between 10 to 35 deg with negligible efficiency loss. Optimum angle for solar panels.

On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north. In 7 of australia s 8 capitals the best angle is at least 3 degrees less than the latitude. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49. It s a common belief that panel tilt from horizontal should equal a location s latitude but this is not quite correct.

To lean toward more production in the summer tilt your panels at your latitude minus 10 15. We are considering to install solar panels on the north and south facing side of the roof. There is no shading from either side. This article is about the best angle to tilt solar panels for the maximum possible energy yield over a year.

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. The summer optimum tilt angle on the other hand will be 34 15 19. To get the best out of your photovoltaic panels you need to angle them towards the sun. 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.

Most solar arrays are installed at a tilt. 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. The ideal angle for solar panels in australia is usually equal to the latitude angle of the location of the property.

Solar panel angle by zip code. The orientation of the panels and the angle they are tilted will have a greater effect on annual energy production. The roof is tilted at about 15 degrees. 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 angle of your solar array is an important factor in maximizing your energy production. To lean toward more production in the winter tilt your panels at your latitude plus 10 15. The graphic below shows.
