If I get solar hot water will I still have hot water on cold cloudy days?

All solar hot water systems we install come with either an electric or gas booster to make sure you have hot water all year round, even when the sun doesn’t provide enough energy. Your booster will need to be used depending on a range of factors including, system type, family size, roof pitch and orientation, hot water usage patterns and climate conditions. It is normal for the booster to be required during periods of low solar gain (rainy / overcast weather) and during the winter months. The graph below shows the approximate solar gain throughout the year.
