Solar water heating (SWH) is the conversion of sunlight into renewable energy for water heating using a solar thermal collector.elow is a table that gives a rough indication of the specifications and energy that could be expected from a solar water heating system involving some 2 m 2 of absorber area of the collector, demonstrating two evacuated tube and three flat plate solar water heating systems.
