Techno-Economic Investigation of Using Solar Energy for Heating Swimming Pools in Buildings and Producing Hydrogen: A Case Study

Solar energy is a free and environmentally friendly supply of power that has negligible impact on the environment, it long been used by humans through different methods. However, solar technology would use for heating water buildings as an alternative resource, which help reduce CO 2 reduction safe environment. A data analysis was performed using RETScreen software, financial outcomes were calculated two Clearly, software operational with Both methods indicate this project economically feasible. The aim study to evaluate utilization household commercial purposes. first goal explore technical, economic, environmental aspects evacuated glass tube collectors heat in indoor pool building, having area 50 m , city Yazd, Iran. second amount hydrogen can be obtained from installation photovoltaic systems province. results also show will decrease greenhouse gas emissions 142 ton-CO over 20 years useful life collector, thereby indicating possible significant role such emissions. Furthermore, findings installing single X21-345 system performance rate 20% result production 2.1 kg annually.
