This paper presents the design and performance analysis of a hybrid wind and solar energy generation system integrated with a battery bank for a building. Argentina has the world's third-largest wind reserve, which exceeds Spain's and Denmark's, and the planet's second-largest solar reserve. Its wind potential exceeds 2,000 GW, a hundred times the current total installed capacity. An Argentine flag flies over Plaza de Mayo in Buenos Aires, Argentina. Despite endless financial difficulties, Argentina has seen a remarkable. The Southwest of Buenos Aires continues to be a key player in wind energy, hosting 18 out of the 69 wind farms across the country. In October 2024, these projects injected 330 GWh of electricity, equivalent to 23. 1% of the total renewable energy nationwide. The generated electricity can be used immediately or stored in batteries for later use, providing a reliable and consistent energy source even on cloudy days.
