Traffic warning flashers are the perfect applications for off-grid solar power solutions as these flashers use very little power and can easily operate 24/7 or a set schedule depending on the installation requirements. These safety devices are needed to warn drivers of upcoming obstacles and hazards on the roadway, school zones or pedestrian crossing areas, and vehicle overheight detection systems.
The flashers are often located in areas where the electrical grid is not available. Solar powered traffic flashers can be used at these locations without the need for the electrical grid. Solar panels produce their own electrical energy that is stored in batteries which are used to power the flashers. As an added benefit, the flashers will still function during power outages.
Numerous different operational profiles are available for solar warning flashers. One of the most popular options is 24/7 operation, which is the standard configuration. Other applications require only nighttime operation using a dusk to dawn controller. School zone flashers usually require the flashers to operate only for a few hours a day Monday through Friday. This can be accomplished using a time clock that can be set for a weekly program or a more customizable 365 day computer. Push button and remote activation are also available and are most commong for pedestrian crossings.
In the standard configuration, the solar module is mounted at the top of an aluminum pole with a breakaway base. The battery and control electronic enclosure can either be mounted with the solar at the top to deter vandalism, or can be mounted lower on the pole for easy access, and is especially useful for school zone flashers.
The flasher fixtures and informational signs can be mounted anywhere on the pole. The flasher balls are either in a single setup that flashes or double flasher ball setup which wig wag flashes. This means that when one light is on, the other is off, and back and forth. Standard flasher balls are yellow; however, they are available in red and green as well, depending on the needs of the installation. Solar warning flashers provide convenient and functional safety for roadways virtually anywhere it is needed.
