Optimum Angle For Solar Panels In Australia

For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49.

Optimum angle for solar panels in australia.

There is no shading from either side. A minimum tilt of 10 is recommended to ensure self cleaning by rainfall. 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.

The optimum angle varies throughout the year depending on the seasons and your location and this calculator shows the difference in sun. Blantyre is at 15 degrees south almost at the same latitude than darwin in australia. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north. 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.

We are considering to install solar panels on the north and south facing side of the roof. Placing panels flush against these types of roofs will mean less electricity production which will lead to reduced solar savings over time. 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. 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.

To get the best out of your photovoltaic panels you need to angle them towards the sun. It turns out that you can do better than this about 4 better. So for my house in adelaide the ideal solar panel angle is 35 from horizontal. The ideal angle for your solar panels to maximize the power produced over the whole year is simply the latitude of your location.

The next question is at what angle from horizontal should the panels be tilted. The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer. Why is the perfect solar panel angle simply your latitude. 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.

This article is about the best angle to tilt solar panels for the maximum possible energy yield over a year. It s a common belief that panel tilt from horizontal should equal a location s latitude but this is not quite correct. In 7 of australia s 8 capitals the best angle is at least 3 degrees less than the latitude. The roof is tilted at about 15 degrees.
