Explore our leading OEM/ODM engineered solar installations, designed with high conversion panels and commercial-grade waterproof housings.
In the transition to smart cities and net-zero municipal development, professional outdoor illumination represents a key node. As a leading manufacturer of solar lighting systems in China, Ningbo Jianheng Import And Export Co., Ltd. (alongside its dedicated manufacturing arm Ningbo Yuancheng Plastic Co., Ltd.) integrates twenty years of specialized research, structural product development, and state-of-the-art manufacturing to deliver reliable products to municipal, commercial, and wholesale markets worldwide.
Our operations are centered in our modern, automated, and strictly regulated 10,750 square meter production facility in Ningbo. Designed to maximize structural quality and production efficiency, our factory houses 105 skilled technicians specializing in precision injection molding, photovoltaic testing, and automatic PCB assembly. Supported by a 15-member international trade, support, and engineering consultancy division, we guarantee seamless order execution, technical customization, and post-sales support for complex international projects.
High-end solar luminaires must operate reliably in variable climates, from cold, wet northern regions to hot, arid desert projects. We enforce rigorous quality control policies at every stage, from testing incoming materials like high-grade monocrystalline silicon wafers, custom polymers, and optical PMMA, to inspecting the finished systems.
Our manufacturing and engineering facilities are certified to ISO9001:2015 international quality standard. Additionally, our production sites pass social audits to meet the demanding requirements of global retailers and institutional developers under the Business Social Compliance Initiative (BSCI).
Every production run is evaluated to meet regional requirements, securing certifications including CE, RoHS, UKCA, and ingress protection verification (IP65 up to IP68 rating). This ensures full compliance for retail supply chains and public bidding processes in the European Union, United Kingdom, North America, and other key international markets.

Our commitment to quality drives our R&D team to continuously refine the materials and technology used in our solar lighting systems. We target four main performance metrics: energy conversion efficiency, battery life, structural waterproofing, and optical performance.
Moving away from polycrystalline technology, we use monocrystalline silicon panels with conversion efficiencies up to 22.5%. Advanced texturing on the glass surfaces improves light capture in overcast or low-light conditions, maintaining reliable charging performance across seasons.
Our solar systems are built using lithium iron phosphate (LiFePO4) battery chemistry. These batteries provide longer lifecycles, and stable thermal performance under extreme weather conditions. The batteries are paired with customized Battery Management Systems (BMS) that prevent overcharging, deep discharge, and low-temperature charging damage.
Integrating Passive Infrared (PIR) and microwave motion sensors helps optimize battery usage. Our solar street and wall lights automatically dim to 10-20% standby brightness, increasing to 100% output when motion is detected. This extends operation times during consecutive rainy days.
A key focus area is the development of robust, load-bearing outdoor solar deck lights. We utilize thick, CNC-machined die-cast aluminum and high-impact polycarbonate to produce high-durability solar road studs and deck lights capable of handling vehicular traffic loads while maintaining an IP68 dust- and water-tight seal.
Our location in Ningbo, Zhejiang province—a major center for the global hardware and plastics manufacturing industries—provides significant supply chain advantages. This integrated cluster allows us to source raw materials, custom components, and specialized tooling within a tight radius, keeping lead times short and pricing competitive.
Located near the Ningbo-Zhoushan port, our logistics pipeline is designed for efficient international shipping. We maintain direct relationships with major ocean shipping lines and freight forwarders, which allows us to quickly arrange cargo dispatch, streamline customs documentation, and lower transshipment costs for our clients.
We specialize in supporting OEM and ODM projects. Our in-house R&D division uses advanced design platforms to quickly turn product concepts into functional designs. With our local supply chain and automated production machinery, we can deliver functional prototypes within 7 days, helping clients accelerate their product launch timelines.
Our product catalog is engineered to support a variety of landscape designs and functional settings, matching aesthetic appeal with long-term durability in different environments:
We recently supplied custom decorative solar garden light installations for an eco-resort in Western Europe. Faced with short winter sunlight hours and high wind exposure, we provided units with high-efficiency monocrystalline panels and custom stainless-steel spike assemblies, ensuring stable performance through winter weather conditions.
We continue to invest in improving our outdoor lighting catalog. Our new product developments focus on materials like anti-UV PMMA, specialized non-corrosive aluminum alloys, and high-conversion bifacial solar panels, which collect reflected ambient light from the ground to boost charging efficiency.
By using modular, serviceable designs for our batteries and LEDs, we extend the operational lifetime of our fixtures. This reduces electronic waste and aligns with the sustainability goals of international commercial buyers and municipalities.
