Explore our high-performance OEM/ODM solar illumination systems designed for professional outdoor infrastructures, landscaping, and pathway applications.
As a leading solar lighting manufacturer in China, Ningbo Jianheng Import And Export Co., Ltd. represents the absolute pinnacle of technological integration in off-grid luminaires. With a history spanning two decades, our enterprise has grown to become one of the most reliable and forward-thinking suppliers in the industry.
We operate out of a modern, state-of-the-art facility spanning 10,750 square meters, utilizing cutting-edge machinery and advanced structural tooling technologies. Supported by 105 highly skilled engineering and assembly specialists and 15 administrative and logistics coordinators, we maintain seamless OEM/ODM services for clients globally.
For custom OEM/ODM operations managed under Ningbo Yuancheng Plastic Co., Ltd., we recognize that regulatory alignment, structural longevity, and system performance are paramount for project developers and municipal distributors. Our production system is fully integrated under the ISO9001 and BSCI systems, ensuring absolute traceability from the silicon wafer to the finished optical housing.
Every OEM 20W solar street light batch undergoes rigorous thermal testing, salt spray corrosion evaluation (vital for coastal projects), and IP rating verification. Our export-grade luminaires carry complete certifications, including CE, ROHS, and UKCA, satisfying the most stringent national power and safety directives.
An in-depth analysis of off-grid solar street light design parameters, supply chain optimization, and localized system tuning.
In a professional 20W solar street light configuration, the conversion efficiency of the photovoltaic (PV) panel directly dictates the system's power generation capacity. We utilize Grade-A monocrystalline silicon cells with conversion efficiencies exceeding 22.5%. This is critical for compact street light housings, where surface area is limited but daily energy generation must remain high, even during overcast conditions.
By optimizing the layout of the bypass diodes, our custom panels minimize localized shading losses. The monocrystalline solar glass is treated with an anti-reflective coating to maximize light capture across low-incidence solar angles, ensuring that energy harvesting starts early in the morning and continues until dusk.
Technical Insight: A standard 20W LED system with 180lm/W efficacy delivers up to 3,600 lumens of continuous light output. Designing for this output requires balanced calculation of battery capacity, solar irradiance ratios, and regional peak sun hours.
Battery performance determines the lifecycle of an off-grid street light. Our systems utilize Automotive-Grade Lithium Iron Phosphate (LiFePO4) battery packs, replacing outdated Lead-Acid or Ternary Lithium cells. LiFePO4 cells support over 3,000 charge cycles at 80% Depth of Discharge (DoD), yielding an operational lifetime exceeding 8 years.
Furthermore, our integrated Smart Battery Management System (BMS) controls charging parameters dynamically based on temperature. This prevents thermal runaway in hot climates (e.g., Middle East, South America) and features low-temperature heating protection for high-latitude regions (e.g., Northern Europe, Canada).

A key failure point of standard street lights is the lack of localized tuning. Solar street lights must adapt to their destination climate:
Operating from Ningbo, one of China's premier industrial and logistics clusters, allows us to source raw materials, SMT components, and die-cast aluminum alloys efficiently. This concentration lowers production costs, a benefit we pass directly to our global OEM partners.
In addition, our proximity to the Ningbo-Zhoushan Port enables direct shipping lanes to Europe, the Americas, and Southeast Asia. This keeps shipping costs low and transit times predictable, even during peak global freight cycles.
How we ensure project compliance, engineering precision, and reliability across our product range.
We provide rapid tooling modifications and custom optical development within 7 business days, shortening time-to-market for municipal bids and distribution channels.
Our production facilities maintain complete compliance. We pass regular external social and technical audits, ensuring standard operations for global tenders.
We build in high-efficiency trackers and optional communication modules (NB-IoT/LoRa) for real-time monitoring and adaptive dimming.
Technical answers to support wholesale procurement, project design, and compliance verification.
Our facility operates under an ISO9001 framework, starting with incoming raw material inspection (IQC) for LEDs, silicon wafers, and batteries. We conduct online aging tests on 100% of finished units for a minimum of 24 hours, followed by out-of-box auditing (OQC) to ensure compliance with CE, ROHS, and UKCA standards.
We use Grade-A Lithium Iron Phosphate (LiFePO4) battery cells that support over 3,000 charge cycles at 80% Depth of Discharge. This translates to an operational lifetime of 8 to 10 years, compared to 2 to 3 years for traditional lead-acid alternatives.
Yes. We customize the battery size and solar panel wattage, and we program custom MPPT controller dimming curves (e.g., 3 hours at 100% brightness, followed by motion sensor activation or dimmed output during late-night hours) to ensure the system operates reliably through consecutive rainy days.
We support 7-day fast proofing. Once we receive your engineering drawings or photometric requirements, our design and toolmaking team can deliver functional prototypes in approximately one week.
Our facility houses high-speed SMT placement machinery, automated optical inspection tools, and a plastic injection molding shop. This allows us to handle OEM projects requiring custom plastic chassis designs, specific optical lenses, or bespoke battery brackets, all while maintaining close control over quality and cost.
