The Smart India Hackathon (SIH26200) problem statement from AICTE / MIC requests student innovation in software to manage and generate renewable and sustainable energy sources more efficiently [PS]. Renewable generation (primarily solar PV and wind) in India suffers from temporal intermittency, spatial variability, grid integration bottlenecks, and inefficient localized load-battery coordination [KNOWN]. To address these challenges, this dossier presents GridPulse, an Intelligent Decentralized Renewable Energy Management & Generation Efficiency Platform. GridPulse combines high-resolution satellite meteorological ingestion (NASA POWER / Open-Meteo), physics-informed PV generation modeling (pvlib), XGBoost/LSTM short-term irradiance forecasting, and Mixed-Integer Linear Programming (MILP / PyPSA) optimal power flow dispatch [RESEARCHED]. The system provides field-ready offline synchronization, real-time battery energy storage system (BESS) degradation-aware dispatch, demand response scheduling, and an automated diagnostic engine for solar array degradation and fouling detection [INFERENCE].

Forecast Service queries Open-Meteo API [4.2] for 15-minute resolution Global Horizontal Irradiance (GHI), Cloud Cover, and Temperature for the site's latitude/longitude.Dispatch Service passes $P_{solar}(t)$, forecasted load demand $P_{load}(t)$, BESS capacity ($E_{cap}$), and DISCOM ToU rates into a PyPSA linear optimal power flow solver [2.3]. The solver outputs hourly target commands: $P_{charge}(t)$, $P_{discharge}(t)$, $P_{grid_import}(t)$, and $P_{grid_export}(t)$.pvlib calculates the expected theoretical yield $P_{theoretical}(t)$ under clear-sky conditions [1.2]. The Diagnostic Service calculates $Ratio = \frac{P_{actual}}{P_{theoretical}}$. If $Ratio < 0.75$ during clear sky periods for >2 consecutive hours, a "Soiling / String Fault Alert" is published to Redis and pushed to the technician's PWA via WebSocket.| Layer | Selected Technology | Why Chosen | Alternative Considered | Why Alternative Rejected |
