The Direction Solar Panels Face
The direction solar panels face for optimum sun exposure varies depending on location. In Australia, solar panel yields are higher when solar panels face north. All Southern Hemisphere locations should ideally position panels in a northerly direction.
The direction solar panels face, along with their angle, or tilt, at that orientation, are all vital inputs to accurately calculate the solar power for the property. These inputs and the property’s location are needed to calculate the solar energy at a given site.
For Australian conditions, the best orientation for your panels is NORTH. Although, if your commissions do not face north, you can still generate good solar yields.
What if your panels aren’t facing north?
If you live in Perth, and your panels don’t face north, your property may still be suitable for generating solar energy. Conferences can still generate good yields if your property faces east or west. Depending on your roof pitch and location, you will lose somewhere between 10-20% efficiency due to not having panels facing north. It is recommended that you can place the panels in more of a northeast or even northwest direction. This will increase sun exposure to the meetings and improve the system’s ability to generate solar power.
Suppose your property is constructed so that you can only face solar panels in a southern direction. In that case, you will also lose capacity compared to a north-facing solar system.
The table below shows the panels’ efficiency in Perth at different orientations; this is based on a roof pitch of 25°. Read More
