one-year dynamic study of the use of solar water heater for domestic consumption in egypt: an energy assessment

The use of fossil fuels leads to greenhouse gas emissions, global warming, and secondary consequences such as desertification and winds in the middle east and africa, including egypt. the use of renewable energy is the most appropriate solution to prevent the emission of polluting gases. egypt is one of the best places to use solar water heating systems, located in the solar belt. in this paper, for the first time, the best place to use solar water heater (swh) systems is examined using tsol 2018 r(1) software and climate data for residential apartments in 35 stations in egypt. the results showed that sharm el sheikh station with supplies 96.8% of its total heat needs is the most suitable station for using solar water heating systems. according to the studies performed, using solar water heaters in the studied stations generated good energy savings annually (production of 134.5 gwh of solar heat). also, greenhouse gas emissions were significantly reduced (preventing the emission of about 39.2 tons of co2 pollutants per year) and as a result, the government should turn to the use of clean and renewable energy.
