چکیده

Solar energy as renewable and clean energy has a remarkable share in improving the water-energy-food nexus. However, due to occupying a vast area of land, the development of large-scale photovoltaic systems is a serious challenge, particularly in regions with land restrictions. As a solution, it is argued that the installation of the floating photovoltaic systems on the water reservoirs can save land as well as reduce the evaporation rate. The aim of this study is to economically and environmentally evaluate the feasibility of the installation of a ۱۰-megawatt floating photovoltaic power plant on a water reservoir. Results show that the payback period of investment and internal rate of return are achieved at ۵.۲ years and ۲۰.۴%, respectively. It is also found that if only ۰.۳% of the water reservoir surface is covered, evaporation volume will be decreased from ۴۴۱.۲ up to ۵۱۵.۲ thousand cubic meters. Moreover, environmental assessment demonstrates that ۸۴۷۰ to ۱۵۳۱۱ tons of CO۲ and ۲۷ to ۵۲.۳ tons of NOx are not released into the atmosphere. Ultimately, sensitivity analysis proves that if the capital cost is reduced by ۳۰%, the payback period will be shortened to ۳.۶ years. Furthermore, such a project in Chah-nimeh will be profitable as long as the electricity purchasing tariffs are more than US ۰.۰۹۶/kWh.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
