PV System Based On The LCA Energy Analysis Theory

BIPV has become one of the inevitable direction of "green building" development, compared with traditional fossil fuels, solar power generation system with energy conservation, zero pollution zero emissions, save space, easy installation features, has been widely The application, however, the application process to produce photovoltaic power generation system efficiency and production, installation, operation and removal of economic comparison of energy and photovoltaic system on indoor thermal environment and other issues affecting the situation. Therefore, this article by finding scientific theory and mathematical models to solve the problem by simulation analysis.This paper establishes the full life-cycle theory and the combination of BIPV and theoretical basis for the solar photovoltaic system into production, assembly, operation and dismantling of the four areas, covering the entire life cycle of photovoltaic systems. West Ham select airports Bonded hemispherical building as a model by model photovoltaic energy consumption as well as all aspects of statistics derived from the airport after the application of photovoltaic systems life cycle of 25 years to reach a total generating capacity of 5,750,700 kWh. Then the four directions buildings compared to the use of the West photovoltaic systems, yield up to 70.32% and South, only 14 years to recover the investment, while a decrease of about 291.80 t fossil energy consumption of standard coal. The north and east to the yield of-42.16% and-25.45%, easy to use photovoltaic systems. Finally, through numerical simulation to determine the impact of photovoltaic glass curtain wall on the indoor thermal environment can be compared in terms of earnings without consideration. To illustrate the application of PV systems is feasible.
