Solar-powered radar speed signs are intelligent traffic devices integrating solar power supply, radar speed detection, and visual warning functions. In residential areas, school zones, and rural roads, they effectively alert drivers to control their speed, significantly reducing accidents caused by speeding. They serve as a crucial tool in modern traffic speed management.
Compared to conventional speed control devices, they offer three core advantages: firstly, they require no reliance on the mains grid (unlike wired speed signs), allowing for more flexible installation; secondly, they provide real-time speed feedback (unlike fixed speed limit signs), ensuring more precise alerts; thirdly, they are energy-efficient and environmentally friendly (unlike non-solar radar devices), resulting in lower long-term operational costs. Consequently, they are widely adopted in modern traffic management.
This document primarily addresses traffic management authorities, property management companies, school administrators, and procurement personnel. It aims to clarify the product's value within speed control scenarios, providing practical guidance for project selection and procurement decisions.
(1) Solar Panel Performance
Equipped with high-efficiency monocrystalline or polycrystalline silicon solar panels, achieving energy conversion efficiencies of 18%-25%. Even under low-light conditions such as overcast skies or dawn, sunlight is effectively absorbed and converted into electricity to sustain basic device operations.
(2) Robust Energy Storage
Paired with high-capacity lithium-ion batteries, providing backup power for 7-15 days. Even during night-time or prolonged rainy periods, the equipment operates without external power sources, eliminating grid dependency entirely.
(1) Suited for Off-Grid Areas
In regions with challenging grid access—such as rural roads, mountainous terrain, and remote residential zones—no costly power lines are required. This significantly reduces construction complexity and costs while enabling seamless speed management coverage.
(2) Reduced Construction Effort
With no need for road excavation or cable laying, a single unit can be installed by two personnel within 2-3 hours, substantially shortening the construction period and minimising traffic disruption.
(1) Radar Module Performance
Utilises 24GHz microwave radar (77GHz radar optional for high-speed scenarios), with a detection range of 10-300 metres and speed measurement accuracy within ≤1km/h. Features robust anti-interference capabilities, unaffected by environmental factors such as rain, fog, or intense street lighting, ensuring stable speed measurement.
(2) Precise Target Identification
Automatically distinguishes motor vehicles while filtering out interference from pedestrians, bicycles, and other non-motorised traffic. This prevents erroneous speed readings and false alerts, ensuring targeted and accurate speed limit enforcement.
(1) Dynamic Display Functionality
The LED screen displays real-time vehicle speed (e.g., ‘Your speed: 65km/h’) alongside speed limit standards (e.g., ‘Speed limit: 50km/h’). Should a vehicle exceed the limit, the screen automatically flashes red or displays a ‘Speed Limit Exceeded’ icon, enhancing visual impact to prompt drivers to reduce speed proactively.
(2) High-Visibility Design
With a brightness of 8000 cd/m² and a viewing angle of 160°, the LED screen remains clearly visible to drivers from a distance—whether under midday glare or in nocturnal darkness—ensuring timely delivery of warning information.
(1) Robust Housing Materials
Utilising ABS engineering plastic or aluminium alloy enclosures with IP67/IP68 waterproof and dustproof ratings, featuring UV resistance, high-temperature tolerance (≤70°C), and low-temperature endurance (≥-40°C). Withstands harsh weather conditions including torrential rain, sandstorms, and intense solar exposure.
(2) Comprehensive Internal Component Protection
Radar modules and batteries incorporate shock-absorbing gaskets to mitigate vibrations from road traffic, preventing component loosening or damage. Solar panels feature scratch-resistant tempered glass surfaces to shield against external abrasions that could impair energy absorption.
(1) Exceptional Component Durability
Solar panels boast a 10-15 year lifespan, lithium-ion batteries last 3-5 years, and LED screens operate continuously for over 50,000 hours. Core components require infrequent replacement, minimising long-term maintenance expenditure.
(2) Simplified Routine Maintenance
Monthly cleaning of solar panel surfaces (1-2 times) ensures optimal energy absorption efficiency. Absence of complex mechanical parts eliminates frequent servicing, substantially reducing maintenance workload.
Though initial procurement costs slightly exceed traditional speed limit signs, long-term operation incurs zero electricity consumption and minimal maintenance expenses. Calculations indicate a 40%-60% reduction in total cost of ownership over five years compared to conventional equipment, making it an exceptionally cost-effective long-term investment.
(1) Data Recording and Transmission
Supports local SD card storage or remote 4G/Wi-Fi transmission of speed data, recording daily speeding incidents, peak-hour speed distributions, and other metrics. This provides data support for traffic authorities to analyse road speeding requirements and optimise control strategies.
(2) Time-Based Speed Limit Adjustment
Pre-set speed limits for different periods, such as 30km/h during school drop-off/pick-up times and 50km/h at other times, flexibly adapting to dynamic traffic scenarios and enhancing the rationality of speed limit management.
(3) Pedestrian Safety Alerts
In areas such as schools and residential zones, the device integrates infrared sensors. Upon detecting pedestrians, it automatically displays ‘Caution: Pedestrians. Reduce Speed’ on the screen, balancing vehicle speed control with pedestrian safety.
(1) Diverse Mounting Options
Supports three installation methods: pole-mounted (compatible with existing utility poles or streetlight poles), ground-mounted (with fixed base), and portable (with castors for temporary speed restrictions during construction). Flexible selection based on site conditions.
(2) Adaptable to Multiple Scenarios
Widely applicable in school zones, residential roads, rural highways, scenic routes, construction zones, motorway slip roads, and other scenarios, effectively addressing speeding control challenges across diverse areas.

(2) Authoritative Certifications
Products hold international/domestic certifications including CE, RoHS, FCC, or CCC. Procurement and usage comply with legal requirements, mitigating compliance-related legal risks.
Radar modules employ low-radiation design compliant with EMC standards, preventing interference with vehicle navigation systems, ABS anti-lock braking systems, trip computers, and other electronic equipment to ensure driving safety.
Traditional fixed signs merely display static speed limits, which drivers may overlook through inattention. Solar-powered radar speed signs provide real-time speed feedback, enabling drivers to clearly ascertain whether they are exceeding the limit. This more intuitive alert system enhances speed compliance by over 30%.
Wired systems rely on mains electricity, limiting installation to existing power line layouts and making coverage in remote areas difficult. Solar-powered models require no cabling, offer flexible installation locations, and eliminate ongoing electricity costs, resulting in lower overall expenses.
Speed bumps enforce deceleration through physical obstruction, causing vehicle jolts, noise pollution, and accelerated wear on tyres and suspension systems. Solar-powered radar speed signs guide drivers to voluntarily slow down via visual cues, achieving ‘soft speed control’ without equipment deterioration or environmental disruption.
Reduce speeding incidents and enhance road safety; optimise speed limit strategies through data-driven management while lowering installation and long-term operational costs, thereby improving traffic management efficiency.
Effectively control vehicle speeds during peak school hours, creating a safety barrier for pupils' journeys; alleviate traffic control pressures around campuses and bolster parental confidence in school safety.
