Optimum Angle For Solar Panels In Australia

There is no shading from either side.

Optimum angle for solar panels in australia.

This solar angle calculator tells you the optimum angle to get the best out of your system. Why is the perfect solar panel angle simply your latitude. This article is about the best angle to tilt solar panels for the maximum possible energy yield over a year. It turns out that you can do better than this about 4 better.

In 7 of australia s 8 capitals the best angle is at least 3 degrees less than the latitude. Blantyre is at 15 degrees south almost at the same latitude than darwin in australia. The roof is tilted at about 15 degrees. We are considering to install solar panels on the north and south facing side of the roof.

The next question is at what angle from horizontal should the panels be tilted. To get the best out of your photovoltaic panels you need to angle them towards the sun. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north. The summer optimum tilt angle on the other hand will be 34 15 19.

A minimum tilt of 10 is recommended to ensure self cleaning by rainfall. Most australian homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation. It s a common belief that panel tilt from horizontal should equal a location s latitude but this is not quite correct. Books and articles on solar energy often give the advice that the tilt should be equal to your latitude plus 15 degrees in winter or minus 15 degrees in summer.

However the panels can be installed anywhere between 10 to 35 deg with negligible efficiency loss. 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. So for my house in adelaide the ideal solar panel angle is 35 from horizontal. The ideal angle for solar panels in australia is usually equal to the latitude angle of the location of the property.

For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49. Low angle roofs will also face obstacles when it comes to solar panel installation and may require specialized racking if you re looking to tilt them at the optimal angle. The optimum angle varies throughout the year depending on the seasons and your location and this calculator shows the difference in sun. Placing panels flush against these types of roofs will mean less electricity production which will lead to reduced solar savings over time.
