Solar Water Heater
Solar Water Heater – Smart Energy for a Sustainable Future
A solar water heater (SWH) is an eco-friendly system that uses sunlight to heat water for residential, commercial, or industrial purposes. It converts free solar energy into thermal energy, significantly reducing electricity or fuel costs and contributing to a cleaner environment.
Types of Solar Water Heaters
1. Flat Plate Collector (FPC) System
- Made of copper or aluminum plates.
- Highly durable and suitable for hard water areas.
- Ideal for households, apartments, and industries.
2. Evacuated Tube Collector (ETC) System
- Consists of glass tubes that efficiently absorb heat.
- Cost-effective and performs well even in cold climates.
- Commonly used for residential applications.
