Research On The Application Of Solar PV In Buildings

In recent years, energy consumption has been a hot social issues are more andmore attention, especially in the huge building energy consumption has a heavy burdento society, and the development of clean renewable energy, to solve this The most directway a problem. Solar energy as a clean energy source, also has a long history ofapplication of solar photovoltaic applications, but it is only in recent years theprogressive development of solar photovoltaic technology in buildings, but also onlyrecently began to wide attention the. Governments have also introduced a lot of thepolicies for the promotion of solar photovoltaic applications, but because of itsapplication, the main material of solar photovoltaic cells have an inevitable problem ofenvironmental pollution and high cost, therefore, on its application prospects of thecurrent academic there are two different voices, this paper is aimed at this stage theapplication of solar PV in buildings analyzed in terms of environmental and economicanalysis can be extended and concluded.First of all, for the application of the principle and the status quo of the solarphotovoltaic summarizes and analyzes the current development of related industries athome and abroad, as well as China’s current development of the solar PV industry chain.Second, the focus select the most widely used polycrystalline silicon solar cells andtechnology is relatively new amorphous silicon thin film battery in-depth study andcomparison, calculate the energy payback period of the polycrystalline silicon cells, andsummed up the current energy principle-based life cycle assessment payback periodcalculation to demonstrate analysis, and amorphous silicon thin film battery productionprocess for environmental impact analysis; In addition, from the perspective of buildingeconomics, making use of static investment payback period and dynamic paybackperiod analysis of two cell The economic performance of the relevant data, to providereference data for the development of the industry of solar photovoltaic cells, and alsoprovides a theoretical basis for the inclination of the solar photovoltaic policy.Then, Analysis of our current solar photovoltaic building application form. Solarphotovoltaic building policy support from the policy level analysis, and to study theproblems of the existing mechanisms.Finally, China’s solar photovoltaic building development policies and measures should be vigorously developed on BIPV solar photovoltaic applications in theconstruction field of application, as well as building new direction of development ofsolar energy photovoltaic, and national policy to guide the direction of the industry.Methods and conclusions of this study provide a reference for the sustainabledevelopment of the construction industry of China’s solar photovoltaic, and solarphotovoltaic industry policy formulation.
