Industrial performance engineered to deliver continuous night-long illumination across commercial & municipal pathways.
Founded on a commitment to clean energy innovation and superior mechanical engineering, Ningbo Jianheng Import And Export Co., Ltd. (operating globally with manufacturing operations powered by Ningbo Yuancheng Plastic Co., Ltd.) stands as a preeminent pioneer in the commercial photovoltaic lighting industry. Over a stellar 20-year history, we have integrated vertical production paradigms to serve top-tier international retailers, builders, and distribution networks.
Our expansive production footprint covers over 10,750 square meters of state-of-the-art facility space. Housing more than 105 highly specialized technicians alongside 15 customer support and logistics coordinators, we maintain the operational agility required to run round-the-clock assembly schedules. By pairing raw materials intelligence with automated manufacturing platforms, we ensure your volume orders achieve precision consistency from the first to the millionth unit.
We engineer absolute reliability into our hardware, validated by globally recognized industry standards.
At Ningbo Yuancheng Plastic Co., Ltd., quality control represents a non-negotiable operational baseline. Our internal labs conduct strict inspections covering raw ingress inspection (IQC), in-process verification (IPQC), thermal shock chamber assessments, and IP65/IP67 ingress testing to safeguard luminaire integrity in the harshest environments.
The engineering behind our Up and Down Solar Wall Lights centers on maximizing ambient lumens while minimizing light pollution. Dual-direction illumination delivers a striking volumetric beam angle, cascading both downwards to illuminate pathways safely, and upwards to wash architectural facades with glare-free, warm light.
By leveraging custom optical lenses, we concentrate light beams (typically 60° to 120°) to prevent scatter, ensuring high lux delivery relative to battery consumption. Our configurations utilize high-density SMD2835 or COB LED arrays, generating up to 100-120 lumens per watt. This directional configuration also prevents glare, creating a sophisticated visual profile for B2B distributors targeting high-end commercial projects.
How our vertically integrated production plant mitigates global shipping risks and accelerates time-to-market.
Leveraging in-house high-tonnage injection molding machines and rapid tool-making departments, we supply fully functional custom OEM samples within 7 days. This allows clients to test market fit with zero downtime.
Operating as both plastic processor and circuit board assembler gives us absolute control over raw materials. We minimize external margins, passing 12-15% cost savings back to our B2B procurement partners.
Situated in Ningbo, adjacent to one of the world's premier deep-water shipping terminals (Ningbo-Zhoushan Port), we minimize inland freight costs and secure preferential carrier allocations, guaranteeing timely global shipping.
Visualizing our cleanroom SMT assembly lines, toolings, and comprehensive product testing zones.
Our research and development pipeline addresses the primary limits of modern solar products: conversion efficiency under low light, and battery pack degradation over multi-year cycles.
Migrating from typical 17% efficiency polysilicon panels to premium N-Type monocrystalline cells, reaching a 23.5% conversion rating. This ensures robust charging during cloudy, high-latitude winters.
Developing embedded Maximum Power Point Tracking (MPPT) logic in our wall lights. This technology auto-tunes voltage input parameters, capturing up to 30% more energy during partial shading.
Transitioning standard lines to premium LiFePO4 packs, securing over 2000 discharge cycles. This ensures a reliable product lifespan of 5+ years, even in extreme sub-zero or high-desert environments.
Whether sourcing for commercial real estate developments, high-volume retail shelf space, or large-scale municipal infrastructure, we tailor solutions to match your project demands.

We believe customization is about more than just stamping a logo on generic housings. Our engineering design process involves tuning the circuit design to deliver optimized discharge curves based on the installation destination's average solar irradiance index.
For example, if your shipment is bound for northern European territories with short winter days, we can adjust the controller firmware to start at low-lumen consumption and scale up only via PIR motion sensors. If destined for warm desert climates, we optimize internal cell spacing and battery shielding to survive prolonged thermal stress. That is the depth of service Ningbo Yuancheng Plastic Co., Ltd. delivers to each partner.

For existing designs with custom branding, our production turnaround is generally 25-30 days upon receipt of sample sign-off and deposit. Custom tooling runs (new product molds) require an additional 25 days for steel injection mold fabrication.
By default, we utilize high-conversion monocrystalline solar panels paired with intelligent battery controllers. The controller automatically drops the output current in low battery states, preserving dim ambient illumination all night. We also recommend sizing up to our LiFePO4 battery variants to handle freezing temperatures without typical discharge drops.
Yes. Because we control the SMT production line, we can populate circuit boards with custom LEDs. We offer standard ranges from warm yellow (2700K-3000K) to cool daylights (6000K-6500K) with a CRI rating up to Ra>80 to match high-end residential landscaping specifications.
Our housings are manufactured using precision high-pressure injection molding. This ensures tight tolerances and prevents warping. We apply food-grade silicone sealing gaskets at all joints, and every batch undergoes IP65/IP67 verification in our high-pressure water spray test chambers before packaging.
Our logistics specialists handle everything from FOB Ningbo/Shanghai pricing structures to CIF port deliveries. We provide full compliance documentation (CO, Form E, CE certificates, MSDS battery documentation) to ensure seamless customs clearance in North American and European ports.
