Born in Singapore with a vision to bring inexpensive, environment-friendly, energy saving Grandcell rechargeable batteries to the market.
We developed a new solar lighting system called Grandsolar, with it’s base of operation in Singapore, using Grandcell rechargeable batteries for gardens and homes. Grandsolar lamps and Grandcell batteries are available in South Africa, Malaysia, China, Greece, Brazil and Spain.
We are proud to announce the launch of our Grandsolar lamps in Indonesia in 2009.
Sunlight shines on the 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.
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.
