Are you planning to invest in buying a good quality solar panel system of a suitable size for your home?
The amount of energy it can generate will depend on the roof facing. The tilt angle, direction, shading, and size directly impact the amount of energy generated by a solar panel. Before going for solar panel installation in Sydney, you need to carefully understand how your roof direction will impact solar energy generation.
Solar Panel Direction is Crucial
The solar panel direction is vital because solar panels that face the worst direction (south) generate almost 28% less energy than those facing the best direction (north). Since Australia is a country located in the Southern hemisphere, the sun’s direction moves towards the north. Hence, solar panel orientation towards the north will give maximum solar output. The solar panel direction towards the east or west will also generate solar power, but at an efficiency which would be 10-20% less compared to a north-oriented solar panel.
Solar Panel Orientation with a South Facing Roof in Australia?
Most people consider solar panel orientation towards the south direction to be a big mistake. Is it really so?
If the solar panel direction is towards the south, it will produce the least amount of energy compared to other directions. If other orientation options are not available due to the roof direction, south-facing solar panels will definitely be a viable option for those looking to reduce their monthly electricity bills.
Have a south-facing roof in Australia? Don’t worry.
South-facing roof with a steep tilt is not an ideal place for solar panel installation. However, south-facing solar panels, which were once supposed to be the worst option, are no longer a major issue for Australians having south-facing roofs.
What is the reason behind this change?
The Lower Price of Solar Panels
The solar industry in Australia has grown by leaps and bounds over the years. A solar cell that cost 5 AUD in 2010, now costs only about 0.93 AUD. With the increasing demand for solar panel installation in Sydney, this cost is expected to come down even more in the future.
What does this mean for you and all other Australians having a south-facing roof?
If you are looking for solar panel installation in Sydney, there is no need for a north solar panel direction. If the solar panel orientation is towards the south, power will still be generated. However, it will be less compared to the other directions. Solar panel installation on south-facing roofs will help save money on the power bill.
If any other solar panel orientation is not available, investing in south-facing solar panels makes sense. At the end of the day, if you don’t have a north-facing roof does not mean that solar panel installation is impossible.
