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.

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. North if you are on an old 44 52 cent feed in tariff and want to sell power back to the grid. 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.

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. There is no shading from either side. We are considering to install solar panels on the north and south facing side of the roof. Each situation is unique in terms of roof angle property layout and power consumption.

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. East west if you are on a low 6 12 cent feed in tariff and you want to maximise your morning and afternoon production. Therefore the best angle for your solar panels is the one that allows the panels to get the most direct perpendicular light. In the northern hemisphere the general rule for solar panel placement is solar panels should face true south and in the southern true north.

However there is a difference between magnetic south and true south that must be considered. 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. Usually this is the best direction because solar panels will receive direct light throughout the day. If your property is located in the northern hemisphere panels facing south will perform best.

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. The roof is tilted at about 15 degrees. Solar power rocks has been referenced by. Blantyre is at 15 degrees south almost at the same latitude than darwin in australia.

Anything more or less than this will reduce efficiency far too much. However there are many very good options available. 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.
