# Energy Models Overview

Daly's energy model is a physics-based PV production pipeline built around pvlib and Daly-specific shading/loss logic.

## Model Characteristics

* Weather-driven simulation using timestamped irradiance and meteorology
* Array geometry support for fixed-tilt, tracker, and rotational floating layouts
* Near + far shading support, including 3D shading-scene integration
* DC and AC loss chain with explicit loss attribution in outputs
* Async execution through worker tasks for large model runs

## Versioning

Energy model inputs support `schemaVersion`, and outputs include `algorithmVersion` (for example `v3.1.0`) so integrations can track behavioral revisions.
