Solar panels convert sunlight into an electric current,Website:http://www.topololighting.com, they do not store power. Amorphous solar panels are created by spraying silicon onto glass in very thin layers, and are commonly known as thin film solar panels. This process allows them to be better at generating electricity in all lighting conditions, including cloudy or shady environments. Amorphous solar panels are best for smaller output needs, temporary set ups, and areas that do not receive predictable sun conditions. These solar panels ensure your lights will work anywhere, anytime!Using the power of the sun, light any dark area and add extra security with the 80 LED Solar Motion Light. It automatically turns on when motion is detected for optimal lighting coverage. Ideal for remote locations, garages, pathways, sheds, security and lighting dark areas.
