Best Position For Solar Panels In Australia
The best solar panels are more efficient perform better and will operate for 25 years.
Best position for solar panels in australia. For australia solar power yields are higher when panels face north. However there are many very good options available. We are considering to install solar panels on the north and south facing side of the roof. 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.
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. Therefore the best angle for your solar panels is the one that allows the panels to get the most direct perpendicular light. If your property is located in the northern hemisphere panels facing south will perform best. East west if you are on a low 6 12 cent feed in tariff and you want to maximise your morning and afternoon production.
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. Usually this is the best direction because solar panels will receive direct light throughout the day. However there is a difference between magnetic south and true south that must be considered. 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.
There is no shading from either side. Each situation is unique in terms of roof angle property layout and power consumption. Within the brisbane solar industry most people will tell you that the ideal location to place to put your panels is. 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. 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. North if you are on an old 44 52 cent feed in tariff and want to sell power back to the grid. While the sun is in a higher position in the sky during the summer and lower position during the winter it has an average position right in between the two seasons.
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. In fact all southern hemisphere locations should ideally position panels in a northerly direction. Anything more or less than this will reduce efficiency far too much.
