Empirical SCADA Telemetry and Simulation Dataset for 35 kW Rooftop Solar PV System in Pune, India

This open-access dataset contains 12 months (35,040 intervals at 15-minute temporal resolution) of empirical operational telemetry and physics-based simulation benchmarking for an institutional 35 kW rooftop solar photovoltaic (PV) installation located at DES Pune University, Pune, India (18.5319° N, 73.8498° E). The dataset supports research in renewable energy forecasting, smart building energy management, and Edge-AI microgrid deployment. It incorporates localized climate dynamics including seasonal monsoon cloud intermittency, high summer ambient temperatures, and thermal inertia derating.
