By converting solar energy into electricity, the solar panel charges the battery during the day and the built-in sensor turns on the light automatically at dusk.
If no enough sufficient sunshine, you can just replace the rechargeable AA battery and it will work. Note, the replacement battery should also be rechargeable.
Note: The lights may get rusted outside, but that will not affect the look in the night

Installation:

Firstly put the stake onto the tube at the back as the picture shows, then find a place for the lights with clear and full exposure to the sun and insert the stake into the ground. If the ground is too hard, do not twist or hammer it with force, please try to soften the ground with water and then insert it into the ground;
Secondly, please expose the solar panel to direct sunshine and make sure the solar panel faces right to the noon sun. The volume of solar energy converted and stored everyday decides lighting performance. It varies with the intensity of sunlight, user's geography locations, weather conditions and shift of seasons
