Solar water heating (SWH) is the conversion of sunlight into heat for water heating using a solar thermal collector. A variety of configurations is available at varying cost to provide solutions in different climates and latitudes. SWHs are widely used for residential and some industrial applications. A sun-facing collector heats a working fluid that passes into a storage system for later use. SWH are active (pumped) and passive (convection-driven). They use water only, or both water and a working fluid. They are heated directly or via light- concentrating mirrors. They operate independently or as hybrids with electric or gas heaters. In large-scale installations, mirrors may concentrate sunlight into a smaller collector.

Key Features:

✅ Installed on the roof for maximum sunlight exposure.

✅ Collector & Insulated Tank: Stores hot water efficiently.

✅ Cold water gets heated in the collector and moves to the tank.

✅ Hot water remains hot for up to 24 hours due to insulation.

✅ Works independently or as a hybrid with electric/gas heaters.
