Modeling Construction and Multidimensional Performance Study of Urban Rooftop Solar Photovoltaic Agriculture

With the growing global energy demand and the gradual improvement of public awareness of environmental protection, the development and utilization of renewable energy has become an important way to solve the energy crisis and environmental problems. Solar photovoltaic (PV) technology, as a promising clean energy technology, has been widely used in the field of energy supply. As an underutilized urban space, urban rooftops contain great potential for development. By utilizing solar photovoltaic as a clean energy source, it can not only reduce the dependence on traditional energy sources, but also combine it with agricultural cultivation organically, providing an effective solution to deal with the problems of food security, resource shortage, and environmental pollution that arise in the process of urbanization. This study takes rooftop photovoltaic power generation system as the research object, and with the goal of maximizing the use of limited roof space, the performance of photovoltaic panels is tested and its layout is optimized. At the same time, the power generation is simulated by professional simulation software and modeled by Matlab, and the power generation model is built by Simulink to provide data and theoretical support for the efficient operation of rooftop PV power generation system. In addition, this study deeply analyzes the impact of PV panels on the microenvironment of crops growing under the panels, optimizes the agriculture-photovoltaic complementary system, achieves water saving of more than 20%, and increases the dry weight of crops by 24.32%, and lays a foundation for the synergistic development of rooftop electricity and agriculture in the city.
