Abstract
This abstract provides a quick review of the points made about solar water heater parts. In order to effectively use solar energy for water heating, it is necessary to have a steel frame, collection box frame, insulation, heat exchanger pipes, absorber plate, and glass surfaces. While existing designs have been functional, there is room for improvement, particularly in the areas of material choice, insulation technology, and heat exchanger pipe design. Energy conversion efficiency and environmental effect have both benefited from improvements in these areas.
