Since there are no lights at the majority of typical bus stops, it is not easy to check bus schedules or routes after night falls. Bus stops can look more attractive with lights and even advertisings can be placed, as electricity is generated and supplied to turn lights on by installing several regular pieces of photovoltaic modules or flexible modules on the round roof of a bus stop.
Short circuits, which cause electric shocks, never occur in stand-alone photovoltaic power generation systems.
The system can be easily installed at places where it is difficult to supply electricity. A battery used by our stand-alone photovoltaic power generation system is a solar-gel battery manufactured especially for photovoltaic power systems, which does not require repairs. Power failures, therefore, will not occur.
