24 hours in the life of a Green Sun light
First light — lamp off
The panel senses the sky brightening and the controller switches the lamp off by itself. No timers, no switchboard, no electricity bill.
Illustrative cycle based on our street-light datasheets: dusk-to-dawn, 6 h at 100% + 6 h at 50%, 2-day autonomy.
