Best Position For Solar Panels Perth

This is because the sun is always in the southern half of the sky in the northern hemisphere.

Best position for solar panels perth. 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. Once again referring to the graph above one can see that even northeasterly and northwesterly facing panels will be largely operating at around the 90 of their rated outputs. Perth receives a lot of sun throughout the year however the winter months and the shoulder seasons do see a considerable drop in sunshine. 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. This depends on both the direction of your roof and the pitch of the roof. If your property is located in the northern hemisphere panels facing south will perform best. True south or the geographic south will yield the best results overall.

While the angle of your solar panels is important a more important factor in your energy production is going to be the direction your panels face. The ideal angle for solar panels in australia is usually equal to the latitude angle of the location of the property. Panels that face north will produce the most electricity overall. North facing solar panels are often the best choice for people who are at home during the day.

There is of course deviance throughout the seasons but ideally solar panels should be facing as close to true north as possible to reduce the impact that the winter seasons have on energy yields. This means that for best results the roof pitch of your property should ideally be equal to the latitude angle with the panels mounted at the same angle as the roof. This data assumes an optimal 32 pitch for perth see next section for details on optimal panel angles. The direction solar panels face along with their angle or tilt at that orientation.

For the best results solar panels should be oriented towards the south. By solar choice staff on 24 june 2019 determining the orientation and tilt angle of your solar power generation system is one of the most important considerations in designing your solar power system. Are vital inputs in order to accurately calculate the solar power potential for a property. Solar panels installed on a roof facing southwest or southeast will generally produce about 8 less power than the same panels in the same climate on a south facing roof.

Australia being in the southern hemisphere experiences a sun that is predominantly coming at us from the north. 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. As we have mentioned before in the southern hemisphere due north is usually the best orientation for panels.
