A curated selection of our cutting-edge solar lighting systems engineered for versatile architectural integration and high-performance sustainability profiles.
The transition toward zero-emission building materials and smart architectural envelopes has elevated the role of localized photovoltaic generators. While outdoor solar lighting has achieved near-complete market saturation, the commercial segment is witnessing a monumental paradigm shift: the rise of solar indoor wall lights. By utilizing highly sensitive crystalline modules and low-lux harvesting technology, modern indoor solar assemblies decouple interior structures from traditional grid dependencies, providing resilient microgrid backups during standard grid outages.
Indoor lighting systems must respond effectively under mixed light sources (ambient sunlight penetrating glazing, incandescent, and LED emission profiles). Engineering custom PV cells for these specific lux bands is key to modern structural designs.
Multinational conglomerates face rigorous ESG audits. Installing indoor lighting systems powered by clean, localized solar cells directly reduces Scope 1 and Scope 2 emissions, offering an direct track to net-zero certifications.
Municipal and commercial building codes increasingly require fail-safe illumination pathways. Solar indoor systems operate independently from internal wiring, offering critical light during grid grid collapse.
Ningbo Jianheng Import And Export Co., Ltd. (mainly operating on OEM/ODM orders as Ningbo Yuancheng Plastic Co., Ltd.) represents the apex of solar light manufacturing. Founded on a legacy spanning two decades, our facilities have grown to support a highly specialized operational flow that services international distributors, municipal developers, and OEM brands.
Spanning an expansive footprint of 10,750 square meters, our assembly and machining zones are equipped with high-throughput injection systems, automatic SMT placement apparatuses, and specialized environmental Chambers. Supported by 105 highly trained technicians and a dedicated logistics and customer service unit of 15 specialists, we ensure that B2B partners receive highly engineered components on schedule.
Quality assurance is the foundation of our B2B engagement protocol. We utilize a comprehensive multi-gate quality validation framework that screens all raw materials before they enter the production lines. Every module undergoes in-situ optoelectronic efficiency testing, battery charge-discharge cycle validation, and water-resistance metrics mapping.
Our production floors adhere to top international production standards. Our facilities are fully BSCI certified and ISO9001 certified. Additionally, our product lineups carry individual CE, ROHS, and UKCA certifications, allowing seamless compliance validation across major global markets including North America, Europe, and the UK.
At Ningbo Yuancheng Plastic Co., Ltd. (Ningbo Jianheng), our technology pipeline is geared toward solving two primary challenges: maximizing solar energy conversion efficiency under non-ideal angles, and increasing battery longevity in climate-controlled indoor spaces. Our technical roadmap highlights our focus on clean energy innovation:
Our solar outdoor products deploy high-grade monocrystalline silicon arrays that yield up to 22% conversion efficiency. For indoor transitions, we integrate amorphous silicon (a-Si) configurations that function optimally under ambient artificial light (from 150 to 500 lux), maintaining steady charging profiles even under diffuse fluorescent or LED output.
By transitioning from traditional Lead-Acid or standard Ni-MH chemistries to advanced Lithium Iron Phosphate (LiFePO4) and high-density Lithium-Ion modules, our systems guarantee up to 3000 charge cycles, smart heat management profiles, and deep discharge protections.
We offer highly integrated circuit designs including split-type solar controllers, multi-stage PIR motion sensors, remote RF control interfaces, and ambient light sensors (LDR) that dynamically dim the LEDs depending on natural lighting penetration.
Our design process utilizes high-accuracy engineering to deliver robust performance in demanding environmental applications. In order to ensure IP65 and IP67 weather-proofing, our engineering teams deploy strict testing protocols during both the prototype stages and bulk manufacture runs.
Modern B2B clients demand custom applications. Our lighting assemblies can be tailored to meet regional certifications, aesthetic requirements, and functional challenges across various environments:
In remote, off-grid eco-lodges, trenching and cable laying can disrupt sensitive local ecosystems. Our custom-designed solar indoor lamps and hanging lanterns preserve nature while delivering high-efficiency lighting.
Dynamic retail displays utilize custom solar systems—such as solar house numbers, pathway accents, and motion-sensing lights—to reduce grid power usage and match sustainable retail themes.
Warehousing zones deploy heavy-duty split COB sensor lamps. By positioning the monocrystalline solar panels outdoors and routing the light emitter inside, high-intensity interior lighting is achieved sustainably.
Residential developers use our customizable solar lighting systems to add eco-friendly appeal, helping them secure LEED and green building certifications.
Managing global logistics requires precision and end-to-end transparency. We control the supply chain from our Ningbo base, coordinating raw component sourcing, assembly, final quality gates, and port delivery. This ensures high-throughput efficiency for our global OEM/ODM partners.

Our solar indoor wall lights utilize highly sensitive amorphous silicon (a-Si) thin-film photovoltaic panels. Unlike traditional monocrystalline panels that require direct solar radiation, a-Si panels capture broader light wavelengths, converting artificial light (from standard indoor LED, fluorescent, or incandescent fixtures) into electrical energy. For split designs, the light panel is installed outdoors and connected to the indoor wall fixture via a low-loss cable.
We provide a rapid 7-day fast proofing service for standard prototype evaluations. After design approval, our factory leverages high-speed SMT assembly and automated molding systems to scale up to bulk manufacturing, delivering orders within 25 to 35 business days depending on order volume.
We integrate advanced lithium iron phosphate (LiFePO4) battery packs with high thermal and chemical stability. Each battery includes a custom Battery Management System (BMS) that monitors charging cycles, prevents over-charging, and provides over-discharge protection. This ensures safe operation in climate-controlled indoor spaces and commercial facilities.
Our manufacturing facility is certified under ISO9001 and BSCI social compliance guidelines. Our product lines carry CE, ROHS, and UKCA certifications, ensuring smooth compliance validation across EU, UK, and North American markets.
