It’s no secret why Queensland is called the Sunshine State. With days that are commonly long and bright, locals can easily soak up the sun – while their solar panels do the same.
In QLD’s capital city, Brisbane, daylight peaked at 13h 52m last summer and only went as short as 10h 24m in winter. While that’s obviously good for everyone’s mood, it’s also really handy for solar panels.
Solar Power on Cloudy Days
When clouds cover solar panels, they’ll produce between 55% and 75% less than they would on a bright, cool day. While you should still be able to produce enough energy for your home – depending on your household consumption – less energy produced will mean less of a payout from feed-in tariffs.
The Sunshine State
So if sun is so vital for higher solar energy production, are Queensland’s golden beaches and Outback towns the best place for a solar setup? That really depends on where exactly you are. Just check out the data below showing the yearly averages of sunny days in Brisbane and Cairns.
- Brisbane – 126 sunny days; 134 partly sunny days.
- Cairns – 98 sunny days; 137 partly sunny days.
While Brisbane has a lot of luck with clear weather, clouds seem to linger on the Cairns coast, reducing the amount of prime solar production days. So with location being crucial to how much energy you can produce at home, how do the other states compare?
With data from the same study above, we can list the capital cities in order of their average hours of sunshine per year.
- Perth – 3212
- Darwin – 3103
- Brisbane – 2884
- Canberra – 2811
- Adelaide – 2774
- Sydney – 2592
- Hobart – 2263
Although more sunshine means more power, it can also mean more heat. Solar panels perform best in cooler temperatures, so finding a spot that’s sunny and cool will give you the most out of your setup.
