Solahart also has an optional gas-boosted model available where boosting only occurs when hot water is being used.
When a hot water tap is opened, solar hot water flows from the solar water heater through a solar-compatible continuous flow gas water heater. Temperature sensors within this gas heater measure the incoming water temperature, and if the water temperature is less than a pre-set minimum, the gas heater ignites and immediately brings it up to the set level.
The choice of which booster is right for you will ultimately depend on key factors such as your solar hot water system, the climate where you live and your roof inclination.
Will my solar power panels work on cloudy or rainy days?
Like solar hot water collectors, solar power panels still work on cloudy days. According to The Environment and Energy Study Institute in the USA3, even in partly cloudy weather, solar cells could still operate at 80% of their maximum output. Because solar panels can use direct and indirect sunlight to generate power they will still work when the light is reflected or partially blocked by clouds.
Meanwhile, rainy weather can also help to keep your panels operating efficiently by washing away any dust or dirt4. However, if it’s consistently cloudy for several days, the efficiency of the solar panels may be reduced as there are less particles of light available to create a high flow of electricity.
Many Australians are also choosing to add a home battery to their solar power and store the energy they’ve generated throughout the day, for use later on. It’s a smart way to offset your electricity costs and maximise your solar energy usage.
