Solar traffic
control systems are widely used
around the world in developed
municipal areas, highways, and rural
and remote areas where a full-blown
traffic signal is too costly yet
some level of control is needed.
Traffic solar control systems can be
used in solar-powered crosswalk
systems; flashing beacons for school
zones; continuous-duty flashers;
radio-activated systems; and
sensor-activated flashers, and many
other applications on the road, in
airports, industrial areas, coastal
areas, and many others.
The common components
of a solar traffic system include a
solar array comprising a solar
module, mounting structure, system
controls panel, battery, an
enclosure which holds the electronic
controls and batteries, and the LED
lamp assemblies.
A
well-designed system will operate
unattended and requires minimum
periodic maintenance. Maintenance for
solar modules is generally limited
to shading from surrounding plants
and accumulations of dirt on the modules.
A properly-designed solar traffic
system will function in all weather
conditions day and night, and it
will hold and supply enough power
to run the equipment for its duty
cycle. Duty cycle is the number of
hours per day each piece of
equipment in the load will be
operated. The maintenance-free
batteries of the solar traffic
system will usually last from 5 to 7
years.
