Solar water heating
Solar power can be harnessed and used in solar water heating systems. These systems use heat from sunlight to pre-heat water that enters your water tank. Your water heater will then need less energy to reach the desired temperature for all your household hot water needs.
Solar water heating systems can operate year round and typically raise water temperatures by 23 to 28 degrees Celsius, which means you could see savings of up to $175 a year on your energy bill.
