Tezpur Uni's 40kW Off-Grid PV Microgrid: PVsyst Design Study

This academic case study designs a 40 kW off-grid PV microgrid for the Department of Electronics and Communication Engineering at Tezpur University, India, using PVsyst software to meet a 37 kW daily peak load. The simulation optimizes PV panels and inverters based on site-specific solar potential, irradiation, temperature, wind velocity, and other factors, achieving 81.4% system efficiency while fully satisfying building demands. Key methods include load estimation, geographical solar resource calculation, and detailed loss analysis for annual energy generation. PVsyst enables precise sizing and performance modeling, providing data on electrical output, environmental impacts, and optimization. Practical details encompass array configuration, inverter matching, and microgrid architecture for standalone operation, offering actionable insights for institutional or homestead-scale off-grid PV deployments. The study validates the design's ability to handle variable conditions, serving as a replicable template with simulation-driven metrics for practitioners designing resilient, building-integrated renewable systems in diverse climates.
