Best Position For Solar Panels In Australia

While the general consensus in the solar power industry is that either west or south is the best direction for solar panels to face these two options don t necessarily address the needs of every individual solar user.

Best position for solar panels in australia.

Within the brisbane solar industry most people will tell you that the ideal location to place to put your panels is. If your property is located in the northern hemisphere panels facing south will perform best. There is no shading from either side. Solar panels work best when the light hitting them comes in at a 90º angle so the ideal tilt for australian sun is at 32º.

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. However there is a difference between magnetic south and true south that must be considered. Each situation is unique in terms of roof angle property layout and power consumption. Blantyre is at 15 degrees south almost at the same latitude than darwin in australia.

In the northern hemisphere the general rule for solar panel placement is solar panels should face true south and in the southern true north. Sunpower and lg manufacture the best solar panels available in australia both provide the best warranties the highest performance ratio and the most efficient modules. The best solar panels are more efficient perform better and will operate for 25 years. For australia solar power yields are higher when panels face north.

We are considering to install solar panels on the north and south facing side of the roof. 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. Variations in the tilt can make a big difference to efficiency though not as marked as with orientation so strive for somewhere between 20 40º. The roof is tilted at about 15 degrees.

Anything more or less than this will reduce efficiency far too much. 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. Solar power rocks has been referenced by. Usually this is the best direction because solar panels will receive direct light throughout the day.

In fact all southern hemisphere locations should ideally position panels in a northerly direction. However there are many very good options available. Therefore the best angle for your solar panels is the one that allows the panels to get the most direct perpendicular light.
