Off-Grid Solar Power for Highway Safety & ITS
Empowering intelligent transportation systems – cameras, signs, sensors – with autonomous solar energy for safer highways.
Modern highways depend on a range of Intelligent Transportation Systems (ITS) to manage traffic and improve safety. These include surveillance cameras, variable message signs, traffic flow sensors, emergency call boxes, and more. Often, installing or upgrading such systems is constrained by where grid power is available. SunWize’s solar power solutions for highway safety and ITS break those limits, enabling you to deploy critical tech wherever it’s needed. Our stand-alone solar units provide continuous, high-reliability power to keep your intelligent traffic systems online and effective, all without grid infrastructure.
What Can I Power?
Traffic safety and ITS systems rely on advanced technologies, including wireless communications and automated control networks, to improve roadway safety and traffic efficiency. These systems require reliable power to support signal lights, message boards, traffic sensors, and real-time data transmission across remote and distributed roadway infrastructure.
To meet these demands, SunWize Power and Battery specializes in industrial solar power systems designed for transportation applications. Our solutions support traffic signals, ITS equipment, and communication networks with dependable off-grid power, ensuring continuous operation in harsh, hard-to-reach, and infrastructure-limited environments.

Key Benefits
- Uninterrupted Operations: Ensure that traffic management devices – from CCTV cameras watching over highways to traffic signal controllers on remote stretches – remain up and running 24/7. Solar panels charge daylight into battery reserves, so your ITS equipment keeps functioning through nighttime and power outages, capturing incidents and data without gaps.
- Ultimate Flexibility: Place ITS assets at optimal locations, not just near utility hookups. Whether it’s a dynamic message sign on a rural interstate or a weather sensor on a mountain road, solar power lets you install equipment wherever it will do the most good. This flexibility is crucial for comprehensive coverage and quick incident response.
- Reduced Installation Costs: Avoid the high costs of trenching and cabling along highways. Solar-powered units don’t require tapping into the grid, which means less permitting and construction work. This can accelerate project timelines and is especially valuable for remote or environmentally sensitive areas where running power lines would be difficult.
- Field-Proven Reliability: Our highway safety power systems are built to meet DOT standards for durability. Components are housed in NEMA-rated enclosures to protect against water, dust, and vibration from traffic. These systems have been proven in real-world deployments – from desert highways to coastal roads – delivering reliable service life of 10+ years.
- Scalable & Upgrade-Friendly: As your ITS network grows, adding another solar-powered camera or sensor station is straightforward. Each unit is modular. Need more power or additional devices later? SunWize can adapt the solar system (e.g., adding panels or batteries) to support new loads, ensuring your infrastructure is future-proof.
Applications & Use Cases:
- Traffic Surveillance Cameras: Solar-powered CCTV or PTZ cameras monitoring traffic flow and roadway conditions, especially at remote interchanges, tunnels, or border crossings where grid power is absent. Autonomous power keeps the video feeds rolling for traffic management centers and incident detection systems.
- Dynamic Message Signs (DMS/VMS): Changeable electronic message boards along highways that inform drivers of road conditions, travel times, or Amber Alerts. With a solar and battery system, these signs can be installed in distant locations or construction zones without external power, and still update in real time as directed by traffic control centers.
- Vehicle Detection & Sensors: Stand-alone radar detectors, inductive loop systems, or Bluetooth travel-time sensors can be solar-powered to collect traffic speed, volume, and congestion data on any roadway. This is essential for extending ITS coverage to rural highways or secondary roads for a complete traffic picture.
- Emergency Call Boxes: Solar energy can reliably run highway call boxes or crash hotline phones, ensuring motorists can reach help even along stretches of highway with no cellular service. The solar panels charge batteries that power the communication equipment and lights, designed to operate through nights and bad weather.
- Smart Work Zone Systems: Temporary ITS setups in construction zones, including queues of sensor trailers, portable cameras, and automated speed warning signs. Each can be equipped with its own SunWize solar power pack, creating a self-sufficient smart work zone improving safety for both drivers and workers.
