Traffic warning flashers are the perfect applications for off-grid solar power solutions. These safety devices are needed to warn drivers of upcoming obstacles and hazards of the roadway. However, the hazards or crossings 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 an electrical grid extension.
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 and can operate 24/7, rain or shine. The battery backup allows for plenty of storage for day and night operation without fail.
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 dusk to dawn controller. There are also flashers that use pedestrian push buttons that only activate when someone is in a crosswalk.
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. Radio or cellular transmitters/receivers can also be used for activation from a central location if that is what is required by the school district.
In the standard configuration, the solar module is mounted at the top of an aluminum pole with a breakaway base, or a wood pole has been used by some municipalities. The battery and control electronics 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, especially ones that need to be adjusted from time to time such as a school zone flasher system. The flasher fixtures and informational signs can be mounted anywhere on the pole.
Solar-powered traffic flashers also come in various colors, both red and amber, and come with single or double head setups for single flash or wigwag flash operation. This customization allows for specific systems to be used for specific projects.
Solar warning flashers provide convenient and functional safety for roadways virtually anywhere it is needed.
