    The Rise of Autonomous, Solar Street Lights for Cities

    Cities need street lights to function properly at night. The units provide guidance for local residents and offer security around parking lots and commercial locations.

    Street lighting systems are also costly to operate and maintain. Large cities can have thousands of lamp posts around sidewalks, roads, parking lots and public transport stations. A combination of solar and sensor technology, as well as connected networks offer an automated approach to street lighting operations and maintenance.

    Automating LED Street Lights

    In order to maximize energy consumption, solar LED street lights as well as work lights must be strategically operated to only turn on during specific times of the day or night. One option would be to install day/night sensors, which would allow the system to automatically detect the amount of ambient light available in the environment. Alternatively, cities may implement timers or specific time-based controls to prevent activation during day-time cloudy conditions.

    Robust monitoring requires autonomous street lights to be connected to a smart network. This allows an operator to manage a group of LED street lights from a remote location. With such protocols in place, human workers no longer need to physically inspect every street lamp in the area. Sensors around the solar LED street lamps monitor and notify remote operators about downtimes, damage and the real-time status of the units.

    Maximizing PV Panel Designs

    Solar-powered LED street lights must incorporate certain designs, in order to promote reliability. Panels are typically located at the top of the pole, with a defined angle for maximum exposure to sunlight. Some units may come with solar trackers for optimized and automated tilting.

    Sturdy enclosures are needed for durability against outdoor elements, such as rain, dirt and corrosion. An enclosure may also house essential components of the solar street light, including the battery, battery charger, LED driver, wiring and etc.…
