Using solar water heaters has become a popular method of hot water supply in the process of hot water production to be used in household and business sectors. These heaters make a huge impact on the environment by reducing the need for fossil fuel-powered systems, thereby decreasing the greenhouse effects on the planet.
One of the early and conventional types of solar water heaters is the flat-plate collector. This design usually consists of a embedded metal sheet with water circulation channels that allow water to flow past its walls and warm the temperature by absorbing solar radiation. These collectors can further be categorized into two subcategories: passive solar collectors and thermal solar panels.
Another type of solar water heater is the evacuated tube collector. These systems are more advanced and sophisticated and can provide better efficiency in comparison to their flat-plate counterparts.
