How do solar hot water systems work?

Harnessing the sun’s energy

The Department of Industry and Science explains the simple process of how solar hot water systems work, as follows:

Solar hot water systems use solar collectors (either flat panels or evacuated tubes), which absorb energy from the sun to heat water for your home. The heated water is then stored in an insulated tank for when you need it. The solar collectors are usually located on the roof of your home, and they are best positioned facing north.

On cloudy days, or when hot water usage is higher than usual, your hot water system may need a boost. The booster will come on when the temperature of water in the storage tank falls below the thermostat setting and turn off automatically when the water reaches the required temperature. For more control over the system, a manual booster switch and a timer may be installed to ensure you make the most of the amount of energy coming from the sun to heat the water.  A gas booster generally produces less greenhouse gas emissions than an electric booster.

…and here’s how our little in-house graphic designer explains the process….
