How It Works

Grandsolar garden lamps are solar lamps which operate without wiring and can be placed anywhere in your garden that has access to direct sunlight. They provide functional lighting for pathways or accent lighting for flowers and shrubbery. They are easy to install and come on automatically at night, while also turning off automatically when the sun rises.



Sunlight shines on the solar panel.


Solar Panel

The solar panel converts sunlight to electricity.



The electricity is used to charge the batteries inside the lamp for later use at night.


Lamp's Sensor

When the sun sets, the lamp’s sensor automatically detects this and the lamp turns on, with batteries providing power the the LED light bulbs.



The LED light bulbs provide illumination, drawing power from the batteries.



The process is repeated again the following day.
