The environmental value of solar road studs is reflected across multiple dimensions, including energy utilisation, energy consumption control, waste reduction and ecological protection. Through technological upgrades and detailed optimisation, HOAN has further amplified these advantages, achieving a perfect balance between environmental protection and practicality, thereby ensuring that “safety warnings are not compromised, and environmental protection and energy conservation are fully realised”.
The most fundamental environmental advantage of solar road studs lies in their complete reliance on renewable solar power. Requiring no connection to the mains electricity grid, they eliminate dependence on fossil fuels such as coal and oil, achieving zero carbon emissions at source. According to calculations, the use of solar road studs along one kilometre of road reduces annual carbon emissions by approximately 2 tonnes, equivalent to planting 100 trees. Long-term application can effectively contribute to achieving carbon reduction targets in the transport sector, aligning with the global trend towards low-carbon transport.
HOAN solar road studs are equipped with high-efficiency monocrystalline silicon photovoltaic panels (2.5V 150mA), with a photovoltaic conversion efficiency far exceeding the industry average. Even during prolonged periods of cloudy or rainy weather, they can efficiently absorb and store scattered light, without consuming any non-renewable energy. Furthermore, all HOAN solar road studs are ROHS-certified. The production process involves no emissions of harmful gases or heavy metals, and the materials contain no pollutants. From manufacturing to use, the product fully embodies low-carbon and eco-friendly principles, meeting the acceptance requirements for various green transport projects.
Traditional mains-powered LED road studs are energy-intensive and require a continuous power supply, consuming vast amounts of electricity annually. In contrast, solar-powered road studs utilise ultra-bright LED light sources; at equivalent warning brightness levels, their power consumption is merely one-tenth that of traditional mains-powered LED road studs, significantly reducing energy consumption. Furthermore, the LED light sources have a service life of over 100,000 hours, eliminating the need for frequent replacements and further reducing energy wastage and maintenance costs.

HOAN continuously upgrades its energy-saving technology; all solar-powered road studs are equipped with a built-in intelligent energy-saving control system featuring light-sensing capabilities. They automatically enter charging mode during the day and illuminate at night, thereby avoiding unnecessary energy consumption during daylight hours. Furthermore, they automatically adjust brightness according to ambient light levels and increase flashing frequency in rainy or foggy conditions, ensuring effective warning visibility in adverse environments whilst minimising energy consumption. Furthermore, some HOAN solar road studs are equipped with supercapacitor energy storage, enabling them to operate continuously for over 72 hours after just 8 hours of charging. This ensures stable illumination even during prolonged periods of overcast or rainy weather, combining energy efficiency with uninterrupted road safety.
Traditional road studs (plastic reflective studs, standard LED studs) have a service life of only 1–2 years. Frequent replacement generates large amounts of plastic and metal waste, which is difficult to degrade. Long-term accumulation pollutes soil and water bodies, increasing the burden on the environment. In contrast, solar road studs have a service life of 5–7 years, with HOAN’s premium cast aluminium solar road studs lasting up to 8 years. This significantly reduces the frequency of replacement, thereby minimising waste generation at source.
It is also worth noting that HOAN solar road studs are made from environmentally friendly and durable materials such as cast aluminium, high-strength PC and ceramic. These materials are all recyclable; once the product reaches the end of its life, the casing can be reprocessed through professional recycling procedures, achieving a ‘low-carbon cycle’ and further reducing the environmental burden. Furthermore, all HOAN solar bollards undergo rigorous ageing, compression and corrosion resistance tests, with quality far exceeding industry averages. They are capable of withstanding extreme weather and complex road conditions, thereby reducing waste caused by subsequent replacements and balancing environmental protection with cost-effectiveness.
Traditional mains-powered LED road studs require extensive cabling, involving road excavation and damage to vegetation during installation. This not only increases construction costs but also disrupts soil structure and impacts the surrounding ecosystem. The ecological damage caused by cabling works is particularly pronounced in sensitive areas such as nature reserves and rural roads. In contrast, solar road studs feature a wireless design requiring no wiring. Installation involves simply securing them with adhesive or bolts, making the process simple and convenient. A single unit can be installed in just 10 minutes, causing minimal damage to the road surface, vegetation and soil.
For sensitive environments such as ecological conservation areas and rural roads, HOAN has launched a lightweight, eco-friendly version of its solar road studs. By optimising the installation method, the impact of construction on the surrounding ecology is further reduced, achieving a ‘win-win’ scenario of enhanced road safety and ecological conservation. Currently, HOAN solar road studs have been widely adopted in numerous rural ‘Starlight Projects’. By enhancing night-time road safety whilst maximising the protection of the rural ecological environment, they have gained widespread market recognition.
Traditional street lamps and mains-powered LED road studs suffer from severe light scattering, which easily leads to light pollution. This not only disrupts human sleep patterns at night but also affects wildlife navigation, reproduction and foraging, thereby damaging biodiversity. In contrast, solar road studs employ a 360° directional lighting design, precisely projecting light onto the road surface to meet road safety requirements whilst avoiding light scattering. This effectively reduces light pollution, safeguarding the nocturnal environment and biodiversity.
HOAN optimises the brightness and flashing frequency of its solar road studs to suit different scenarios. For areas with high wildlife activity, such as rural and mountainous regions, we offer low-brightness, low-frequency flashing models to minimise disturbance to wildlife. For urban roads and motorways, we enhance light penetration to ensure drivers can clearly identify the studs whilst avoiding direct light into residential areas, balancing safety and environmental protection in line with the ‘Dark Sky’ conservation philosophy.
The environmental advantages of solar road studs manifest differently across various traffic scenarios. HOAN has developed targeted products by integrating the environmental requirements and road conditions of each scenario, ensuring that environmental benefits are realised in every context whilst meeting road safety warning needs, thereby achieving the dual objectives of ‘environmental protection and practicality’.
