Evacuated Tube technology delivers significantly better performance than traditional absorbers in the market today. Their advanced design incorporates tubes that consist of 3 layer of borosilicate glass with a vacuum layer between them. This vacuum acts like a thermos flask, retaining up to 97% of the thermal energy, resulting in increased efficiency. The sun thermal energy then transferred to the manifold via the heat pipe located inside each tube.

Solar water heating system(SWH) in Nepal is the conversion of sunlight into heat for water heating using a solar thermal collector. A variety of configurations are available at varying cost to provide solutions in different climates and latitudes. SWHs are widely used for residential and some industrial applications.
