Mathematical modelling of a Solar-Wind Hybrid system for a Residence

The equatorial regions of the Earth are swathed with sunlight and wind as enormous and renewable energy resources. India, being one of the most densely populated countries with high and increasing energy demand, will gain significantly from renewable energy solutions. This paper will propose a solar-wind hybrid system optimized for the residential energy demands with optimized use of rooftop space, supported by a battery backup for a reliable and uninterrupted power supply. In this system design, the mathematical model developed in HOMER Pro has simulated the combined power generation from solar panels and wind turbines for residential loads. The hybrid system uses VAWTs that have been chosen based on the minimum required maintenance, quiet operation and functionality under different wind directions, and relatively low speeds. They are ideal for installation in rooftops of areas found in urban regions. With reduced reliance on the grid, the hybrid system is improving energy resilience for home users while reducing its ecological impact by lowering greenhouse gases emitted. This integration of solar and wind energy hence comes with a sustainable self-sufficient energy solution making the hybrid systems an important element of the transition toward decentralized and cleaner energy resources to residential applications.
