Concert Stage Power Microgrid (2D)

A festival stage is its own small power grid: a lighting truss and a PA rig that swing hard with the show, a solar array and battery buffer that only give back what the sun banked earlier, and a generator or grid tie standing by for whatever is left over. This 2D schematic runs the exact same full simulated day/night cycle as its 3D sibling — drag the diagram to pan across the rig, scroll to zoom, push the lighting and PA levels up for the headline set, and watch the battery's state of charge drain as the free daytime solar energy runs out, forcing the generator to pick up the slack. It is the exact power-budget trade-off that festival production and sustainability teams size their solar-plus-storage rigs against.
