How Does Solar Street Light Works?

How Solar Lighting Works
1.During the day, solar panels convert sunlight into electricity. This happens due to light photons striking a solar cell and knocking electrons free from the silicon atoms of the crystal structure of the cell.
2.The power generated from the solar is fed through our charge / load controller and charges the battery. 
3.The solar panel acts as a photocell turning the light on at night. The charge / load controller controls the discharge of the battery powering the light fixture to provide accurate lighting operation.
4.The solar panel will sense when it is daylight again and will tell the charge / load controller to turn the light back off in the morning and go back to charging mode.
