Is Daylight Savings Better for Solar?

Is Daylight Savings Better for Solar?

Blog Article

Whilst often confused, solar production is generally the same whether it is daylight savings or standard time, due to the sunlight time only being shifted one hour and not one hour longer. This means that solar daylight savings doesn’t directly affect your solar production.

During the year, Australia’s daytime duration varies depending on the occurring season, and this is what mostly affects overall solar production more than daylight savings times. Obviously, the panel conditions are another contributing factor to efficiency and production, but we’re mainly focused on seasonal changes and daylight savings.

Solar generation around summer vs. winter is much different, not just due to the difference in sun angles, but also the duration of daylight hours. Here is a chart that shows the amount of daylight hours during the year with times for sunrise and sunsets throughout Australia.

 



 

The Sun’s Angle & Orientation

During spring and summer, daylight hours are generally longer, and the sun shines higher in the sky (around 78°) with increased intensity. Comparatively, Autumn and Winter typically get a lower angle of around 31° which results in less sunlight exposure and generation.

Conclusion

Overall, no matter your system specifications or setup, your production will always vary throughout the year with different elements determining the output of your system.
