How winter affects solar panel performance
Cold temperatures don’t affect solar panel performance; the short winter days are what affect solar energy output. June is the worst month for solar energy output because of the winter solstice. The winter solstice is the shortest day of the year, and it typically takes place on the 22nd of June in Australia. Because the sun rises so late and sets so early, your solar panels will receive less sunlight which is why solar panels produce less energy.
Winter, however, are some of the best months for solar panel performance because solar panels perform better in cooler temperatures.
1. Install more solar panels
The simplest way to combat the lower energy production is to install more solar panels. A 6.6kW system in Brisbane will output 20.2kWh during winter, whereas in wither it will generate about 26.4kWh during summer. This output can be increased by converting to a 10kW system. The viability of this tip relies on the amount of space you have on your roof.
