The light is on- from dusk till dawn. That is the goal of the SPIRIT control unit. And that is what the column is designed for. Depending on many factors, it will try to regulate the energy balance to commit to that promise.
Here comes the sun. The SPIRIT control unit has calculated based on the GPS location and astronomical data at what time sun rises. The battery is emptied up to 50% for perseverance (DoD 25-50%, depending on battery technology, location, availability and type) and ready to be charged.

The battery is quite full and will start charging in absorption. Later on in the afternoon, to complete the full charging it will charge the battery in float to get the most out of the sun's power.
Before sunset, the battery status will be determined just as the length of the night. The perfect lighting setting will be selected in order to keep the light on all night long.
The special-designed Alexia- or Anne-luminaire (DC) will be on for the rest of the night till sunrise. During the night a dimming profile may be active, depending on the desired dimming profile and/or the generated energy during the day to keep his main promise: keeping the light on.
