A solar garden light device has at least one lamp, a rechargeable device and a solar array. Each one of the at least one lamp has a casing, a through hole and a light assembly. The casing has a top end. The through hole is defined in the casing adjacent to the top end. The light assembly is mounted in the casing and lights. The rechargeable device has a control circuit and a rechargeable battery. The rechargeable battery is connected electrically to the control circuit and the light assembly. The solar array is connected electrically to the control circuit, converts sunlight to direct current (DC) electricity and recharges the rechargeable battery. Therefore, the solar array can absorb solar energy and transfer solar energy to electric energy to store electricity in the rechargeable battery. Then the rechargeable battery supplies power to the light.
