Global solar water heating (SWH) capacity peaked at 542 gigawatts thermal in 2022, an increase of 3.6 percent compared to the previous year. China is the world's biggest solar water heating market. Between 2009 and 2022, the capacity of solar water heating (SWH) systems worldwide has increased steadily as new policies have helped improve sales. Solar collectors, typically found on a structures roof, are used to convert the suns energy into heat which is then used for heating water.
