Researchers at the Korea Institute of Science and Technology havedeveloped high-performance solar-powered streetlight – Sola LED. Thestreet lamp uses sun’s energy to power onboard LED light forillumination. The energy-efficient system features sun-tracking solarpanels that better the output of the entire system.
Energy generated by solar panels is stored in high-performance lithium batteries, which allows thelights to function even during cloudy days. Sola LED is being claimed to be easy to install and can operate for a longer period of time withoutmuch maintenance.
