New-Generation Lighting for Rural Solar Projects｜Application Case of Sanxing Lighting's "Xingrui" All-in-One Solar IoT Street Light in Township Roads

With the global transformation of the energy structure, the application of new energy technologies in China’s rural areas is rapidly advancing. As a key representative of new energy infrastructure, solar street lights have been widely adopted across townships. However, traditional solar street lights often suffer from issues such as poor resource allocation, low energy storage efficiency, low solar conversion rates, high failure rates, complex maintenance, and outdated appearance—significantly limiting their effectiveness and long-term viability in rural deployments.

As a leading provider of urban lighting solutions, Sanxing Lighting has leveraged its expertise in solution design, product R&D, and intelligent manufacturing to develop a new-generation lighting solution. By integrating smart lighting, IoT, intelligent control software, new materials, and advanced solar technologies, the company successfully launched the high-tech, innovation-driven "Xingrui All-in-One Solar IoT Street Light," which has since been applied in real-world scenarios.

Compared with urban environments, rural townships often face challenges such as underdeveloped infrastructure and insufficient power distribution networks. However, they also benefit from excellent sunlight conditions, making solar-powered street lighting an ideal solution. This not only supports ecological improvement and public lighting but also promotes the growth of green industries such as eco-agriculture and tourism—contributing to coordinated progress across economic, social, and environmental dimensions.

From both economic and environmental perspectives, the Xingrui lights deployed on township roads in Lishigang offer clear advantages. Compared to grid-powered lights of the same specification, each unit can save approximately 262 kWh of electricity annually, reduce electricity costs by about 236 RMB, and lower carbon emissions by around 0.2 tons. These benefits significantly reduce municipal operation costs, enhance the living environment, and serve as a model for building modern, harmonious, and civilized rural communities.

High-Efficiency All-in-One Design

The Xingrui All-in-One Solar IoT Street Light features a modern minimalist design suitable for various road levels. The solar panel is seamlessly embedded within the pole structure, offering an aesthetically pleasing appearance aligned with contemporary design standards. The integrated panel design also maximizes exposure angles throughout the day and across seasons, ensuring optimal solar energy absorption and efficient energy conversion for reliable lighting performance.

The lamp uses monocrystalline silicon panels encapsulated with low-iron tempered glass and TPT material, which are dust-resistant, highly transparent, and anti-aging, achieving a solar conversion efficiency of up to 21%. The power system is based on high-performance lithium batteries capable of operating in extreme temperatures ranging from -30°C to +60°C, with high current charge/discharge capacity and a discharge rate up to 1C, ensuring stable operation in both cold and hot climates.

Smart Control, On-Demand Lighting

Equipped with Sanxing Lighting's MPPT smart controller, the system dynamically adjusts solar energy conversion and storage efficiency. It tracks the panel’s maximum power point in real time to ensure optimal power conversion. Compared to traditional controllers, this boosts charging efficiency by 15–20% under equal power conditions. Even under low-light or cloudy conditions, the controller maintains battery charging. When fully charged, it provides trickle charging to prevent overcharging and ensure battery life longevity.

The MPPT controller also supports intelligent light management, adjusting lighting schedules and brightness levels based on pedestrian traffic, vehicle flow, time periods, and sunlight conditions. This enables on-demand lighting, ensuring continuous operation even during extended periods of rain or low sunlight.

Leading Technology for Sustainable Rural Lighting

The Xingrui All-in-One Solar IoT Street Light fully utilizes solar energy and offers industry-leading performance in solar conversion, battery storage, charging/discharging technology, and smart control platforms. It delivers tangible benefits in energy saving and emission reduction, while its integrated design aligns perfectly with modern rural construction trends.

Looking ahead, Sanxing Lighting will continue to advance innovation in product design and R&D, launch lighting products tailored to diverse application needs, and deepen its development of smart and low-carbon lighting technologies. The company is committed to creating healthier, smarter lighting environments for cities and rural areas alike—lighting up a brighter future for China with the power of technology.
