Solar water heating systems typically cost more than traditional water heating systems to buy and build. In the long run, however, a solar water heater will typically save money. For a thorough study of a solar flat plate collector, multiple variables are involved (FPC). Solar collectors, fluid transport and distribution systems, hot-water storage containers and their control systems are important subsystems. The Solar Water Heating (SWH) Device has the ability to eliminate more than 50 percent of household energy consumption. SWH uses readily available solar energy to preheat water until it reaches traditional water heaters (electric or gas), thus greatly reducing energy use and expenditure. Current research has made several attempts to incorporate a variety of the most significant variables (Solar Energy Factor, Solar Fraction and Energy Factor) into a single energy (thermal) efficiency calculation equation and also to evaluate the cost of different systems relative to traditional systems. The approach used is to score the performance of solar water heating through the use of energy factors, the same efficiency rating that is used for electric and gas heaters. Not only is the EF the factor for determining the water heater model, it is also equally important to take into account the system’s size and first hour ranking, fuel type and overall cost. Depending on fuel prices and electricity tariffs, the cost forecasts are diverse.
