Solar Water Thermal Heating Systems for Village Compound in Egypt

A lot of people utilize renewable energy sources (RESs) for heating, particularly in solar water heaters (SWH). Despite the accessibility and affordability of SWH technologies in Egypt, no comprehensive study has been conducted to explain the potential of Egyptian compounds to provide hot water for village home usage. For this reason, the first dynamical simulation of a solar heating system to supply sanitary hot water (SHW) and the hot water needed to heat 756 villages in the Palm Hilis compound in New Cairo, Egypt, is attempted in this year-long project. The Metonym software, which is modeled in TSOLTM, is used to extract the climate data. In addition to using an auxiliary gas boiler, a one-year dynamic analysis that took into account all potential losses were carried out. Based on the results, the installed collector power of SWHS is 732 kW, and the solar energy contribution to DHW is 14.27 MWh. Solar energy powers 97% of the system. In terms of economics, COE and NPV are 0.00083 and 57072 $/kWh, respectively. In addition, the suggested system has a 4.4-year payback period and costs 0.223 dollars for 1 m3 of hot water.
