They absorb solar energy converting it into heat for use in water heating. Evacuated tubes have been invented in China by Professor Yin Zhiqiang and have already been used for years in Germany, Canada, China and the UK. There are several types of evacuated tubes in use in the solar industry. Skylight uses the most common "twin-glass tube". This type of tube is chosen for its reliability, performance and low manufacturing cost.
