  "raw_analysis": "PVWatts v6 is NREL's (National Renewable Energy Laboratory) photovoltaic performance modeling platform, providing energy production estimates for grid-connected PV systems. This is a mature, government-backed service widely used in the solar industry for feasibility studies, system design, and performance prediction. The platform integrates weather data, system specifications (panel type, inverter efficiency, tilt, azimuth), and geographic location to calculate expected energy output. Target users include solar installers, energy consultants, researchers, and property owners evaluating solar installations. The service provides both simple estimates and detailed hourly/monthly breakdowns. As a government API, it's free to use with API key registration, making it accessible for both commercial and research applications. The v6 designation suggests ongoing development and refinement of the underlying models and data sources."
