This repository is a design portfolio and technical showcase for a solar photovoltaic GIS prospecting and forecasting platform. It does not contain a runnable application; instead, it provides architectural documentation (docs/ARCHITECTURE.md, docs/MODULES.md, docs/AI_FORECASTING.md) and three well-crafted code snippets that demonstrate the engineering patterns behind map-based lead identification, AI roof detection service, and PV generation forecasting. The snippets illustrate professional-level software design: input validation, security boundaries, model routing, fallback strategies, and business logic normalization. The repository serves as a reference for architects and engineers evaluating similar systems, but it is explicitly non-reusable for commercial purposes due to the license restrictions.
