Performance analysis of roof-mounted photovoltaic systems on the office building in Hanoi

Abstract : Building is responsible for more than 40 percent of energy consumption and one third of greenhouse gas emissions. Europe has established the pathway towards nearly zero-energy buildings (nZEB), soon required in every new construction and large renovation in existing buildings by 2020. Achieving nZEB required the use of photovoltaic modules for generating electricity. The rooftops of residential, commercial and office building are ideal places for the installation of PV systems. Recently, in Vietnam, the nZEB becomes an important part of sustainable development and attracts the attention of scientists on the term of " green building " or " smart building " , while photovoltaic systems are in most cases not used in building today. From this framework, we aim to implement the platform that will be dedicated to prototyping and tools to support research and training in the reference building. The first work presented in this paper aims at parametric analysis of 15 kWp PV system applied to a rooftop of a University building in Cau Giay-Hanoi. The study shows the effect of PV module types, and installation tilt angle on the electrical energy yield. The Photovoltaic simulation tool takes an important role in calculating the energy production from the solar panels. PVSyst software as a simulation tool was used to simulate several operating conditions as well as components. The research investigated a complete on-grid PV system by taking into account orientation of PV array under meteorological condition in Hanoi, solar cell technologies and inverter connections. Meteorological data was accessed by MeteoNorm and PVGIS. According to simulation results, the configurations of PV system for reference office building of the University of Science and Technology of Hanoi (USTH), was optimized to facilitate the next phase of smart building research in Vietnam.
