Placing Reflectors for Reducing Payback Period of Solar PV for Smart Buildings

the trend of "Smart" concept may have begun with smart vehicles and smart buildings, but as technology advances, the "smart" trend is compelling over entire cities. Around the world, cities with different capacities are converting their infrastructure, systems, and operations to capitalize on new technologies. But these new smart cities are not just forward thinking when it comes to the best ways to serve the public. Many of them are also revolutionary exertions to integrate sustainability and energy efficiency into developing smart city solutions. Integration of solar power rapidly becoming a symbol of smart city planning. But yet the higher payback period of the solar panels and the low power output has caused low implementation of solar energy technologies in smart buildings. In this research, the main aim is to propose a low capital investment with lower payback period solution for solar panels to be used in smart building as an energy solution. In this research, a mathematical model is presented to find out the best reflector arrangement for a specific location to enhance the solar insolation on a silicon based solar module throughout the day, thereby optimizing the power output of the solar panel. Furthermore, a temperature analysis and the cost benefit analysis with payback period is done to show the financial superiority of the proposed scheme.
