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.
