Investigation of a building-integrated solar photovoltaic-wind-battery hybrid energy system: A case study

In this study, performance of an off-grid roof-mounted Photovoltaic (PV)-micro wind-battery hybrid system is experimentally investigated for the first time, under real varying outdoor climatic conditions for 1.5 years in the Indian Western Himalayan region. With good solar access but low to medium wind resources. The performance of the system during different seasons and weather types (cloudy, partially cloudy, and sunny) shows the maximum monthly generation of 91% by PV with 09% wind system share. The follow-up research areas are also identified for sustainable utilization of available resources, which can contribute significantly to achieve the sustainability goal.
