Best Orientation For Solar Panels In Australia

After finding the best place to install your solar panels your installer will select the ideal tilt.

Best orientation for solar panels in australia.

The direction solar panels should ideally face for optimum sun exposure varies depending on location. For example in brisbane if your panels are facing west 270 and are angled 20 from horizontal you will get 89 of the energy compared to the optimum orentation of north and 30. To get the best out of your photovoltaic panels you need to angle them towards the sun. The tilt of the panels is important because your panels will produce a maximum of energy when the sun is directly perpendicular to them.

This table shows you how much energy you can expect to get from almost any combination of solar panel direction and angle in the capital cities compared to the optimum orientation. For most people in australia the direction you want your solar panels to face is true north and with between 20 50 degrees of tilt depending on how southern or northern you are. The sun is in a different place in the sky and solar panels should face it as squarely as is reasonably possible throughout the day. The optimum angle varies throughout the year depending on the seasons and your location.

This is because the sun is always in the southern half of the sky in the northern hemisphere. This solar angle calculator tells you by location the optimum angle to get the best out of your system. But there are a number of variables in figuring out the best direction. The premise behind this is simple.

In this case for the solar panels to get their best performance a steep angle of 60 is best. While the angle of your solar panels is important a more important factor in your energy production is going to be the direction your panels face. Since most of the sun in the southern hemisphere comes at us from the north the ideal orientation for solar panels in australia is as close to true north as possible. The shed on which we are intending to put the solar panels can be orientated in any direction but we have been given conflicting advice in that one supplier advised us that the best orientation is to have the panels east west facing due to our power needs being more in the morning and late afternoon and others advising north would be best.

This page is designed to help you find the best placement for your solar panels in your situation. Which direction should solar panels face. More optimum orientation of solar panels to get the most from solar panels you need to point them in the direction that captures the most sun. Even small deviations from this direction can reduce a system s efficiency by as much as 15 so this is an important consideration.

Orientation of the panels. During the winter in the northern hemisphere for example the sun is low in relation to the horizon. The effect of orientation on solar output. For the best results solar panels should be oriented towards the south.
