| Abstract |
Recently, due to rapid economic development, the renewable energy industry has been attracting attention as a measure against the primary energy depletion such as rising energy demand and fossil fuels around the world. Solar energy utilization technology, one of the most common eco-friendly facilities introduced in Korea, includes photovoltaic module technology, which converts electricity using a photoelectric conversion device, and solar thermal solar power, Technology and PVT system equipment that combines these. The PVT system refers to a system with a heat exchanger installed on the back of the module to prevent degradation of PV module performance due to excessive solar radiation in summer. As the surface temperature of the module increases, the efficiency decreases and it becomes the main cause of shortening the module life. Therefore, it is possible to improve the power generation by reducing the temperature rise of the module surface by securing the above disadvantages and to reuse the recovered heat for hot water supply and heating,these are advantages.It is also possible to improve the performance by efficiently utilizing energy per unit area. In this study, the performance analysis of the solar thermal (PVT) system was carried out considering the heat storage tank and the hot water supply load. As a result, the initial investment cost is expected to be 11 years, which is more economical than the existing hot water supply facility. |
