Application of a Solar Photovoltaic System for Ventilation of a Livestock Farm in Southern Perú

Despite high solar irradiance in southern Peru, the adoption of photovoltaic technology in rural areas remains limited. This study examines the application of an isolated solar photovoltaic system for the ventilation of a livestock farm in southern Peru. First, the analysis parameters were identified, including geographical location, local solar irradiance, and the ventilation equipment's operating time and energy requirements. A technical–economic analysis was conducted to size the photovoltaic system and assess its feasibility. As a result, the characteristics and specifications of the system components were defined. Additionally, three economic indicators were evaluated: net present value (NPV), levelized cost of energy (LCOE), and payback period. Over five years of operation, the proposed photovoltaic system shows potential for implementation, yielding favorable economic results, including a positive NPV, a moderately competitive LCOE, and a payback period of 3.8 years. The system also avoids approximately 0.165 metric tons of CO₂ emissions per year, demonstrating the environmental viability of using renewable energy for ventilation systems.
