Solar Panel Installation and Design – Things to Know

The first questions that come to mind when you decide to opt for solar panels are where to install them and the optimal way or design to install them. The best way to install your solar panels in Australia is to have them facing north. However, that does not mean that there is no other possible way to install panels if your north side is blocked or shaded.

There have been numerous studies that show that you can have your solar panels installed facing south, or a combination of east and west as well as on flat surfaces, and still have great savings on your power bills. Sometimes you can ensure that the amount you are losing in terms of power production can be offset by adding a few extra solar panels.

Another important element to consider is the output capacity of each panel. While traditionally most solar panel systems had a 1.5kW capacity, most standardised ones now have around 6kW capacity. This means that you can effectively generate more electricity as well.

North-facing solar panels

This is the ideal scenario for installation. It helps to optimise the generation of power during the daytime, thus allowing you to store the extra power in batteries and reduce your energy bills.

East-west-facing solar panels

East or west-facing solar panels help with power generation in the morning. Also, in Australia if you want to beat the summer heat, west-facing panels are better while east-facing helps to generate energy even during winter. However, the overall power generation effectiveness of east-west-facing panels is about 15% less than north-facing solar panels in Australia.

South-facing solar panels

You can generate sufficient power with south-facing panels as well. Their performance in summer is comparable to west-facing panels but their winter production can take a hit. However, over a year, you will still be able to save significantly on your energy bills.
