The Self-Cleaning Solar Light features an automatic wiper that cleans accumulated dust, bird droppings, and fallen debris from its solar panel 6 times a day. By keeping its solar panel clean, this light will maximise its own sunlight exposure, battery life, and longevity. This low maintenance light also features an adjustable angle bracket, a battery level indicator, and a builtin temperature control system that allows it to work in freezing temperatures. All Star 8 solar lights maximise battery life and charge life because they incorporate adaptive lighting, variable frequency and temperature control patented technologies.
