Product details

solar water heating system (SWH) uses sunlight to heat water for domestic or commercial use. It typically heats water to 60–80°C and can supply 70–80% of annual hot water needs, saving significant electricity. Core Components • Solar Collector: Absorbs sunlight to heat water or a working fluid (Flat Plate or Evacuated Tube). • Insulated Storage Tank: Stores heated water while minimizing heat loss overnight. • Supporting Structure & Pipes: Mounts the collector at the proper angle and connects the system to cold water supplies and hot water outlets. • Backup Heater: An electric immersion rod or boiler used during extended cloudy days or winter. Main Types of Collectors • Flat Plate Collector (FPC): A weather-resistant box with a dark absorber plate and a glass cover, ideal for general domestic use. • Evacuated Tube Collector (ETC): Made of double-layer borosilicate glass with a vacuum insulation layer, offering higher efficiency and better performance in cold or overcast weather.
