The solar garden light is an interesting project that uses sustainable energy to illuminate a white LED. During the day the solar panel charges an AA battery, then when it goes dark the board automatically switches from charging the battery to illuminating the LED.
The solar panel is resin encapsulated and therefore waterproof. You will need to make a waterproof enclosure for the rest of the parts. Alternatively the board has been shaped so that it will fit into an old jar.
