The paradigm of modern outdoor illumination is undergoing an unprecedented shift. Driven by net-zero emission mandates and rapid developments in wide-bandgap semiconductor efficiency, solar garden lights have transitioned from residential ornaments to robust architectural solutions.
As a premier China solar garden lights supplier & factory, Ningbo Jianheng Import And Export Co., Ltd. and its sister manufacturing arm, Ningbo Yuancheng Plastic Co., Ltd., are at the forefront of this industrial shift. Over a 20-year history of technological iteration, we have addressed the key pain points of international buyers: battery degradation, weatherproofing failures, poor conversion rates, and supply chain disruptions.
By leveraging advanced plastic injection technologies, high-efficiency monocrystalline solar panels, and intelligent microcontrollers, our product range ensures optimal lumen output even under challenging geographic and atmospheric conditions.
Combining high-capacity engineering facilities with strict quality management system certifications.
Operating from Ningbo, China—the historic heart of precision electronics and mold manufacturing—our factory spans a specialized 10,750 square meters area. The factory floor features automated assembly lines, precision plastic injection molding machines, and an integrated testing laboratory.
Our active workforce includes 105 skilled technicians and production workers, backed by an office management team of 15 experts handling international logistics, custom packaging, and engineering verification. This structural layout allows us to offer standard operations alongside high-mix, low-volume custom configurations.
Why Ningbo is the global benchmark for cost-efficiency and product safety compliance.
We feature fully integrated tooling facilities. This allows us to offer a 7-day fast proofing service, shifting custom lighting designs from engineering prints to physical samples in a single week.
Our raw material testing lab checks each batch of monocrystalline solar wafers, high-C-rate Lithium batteries, and high-intensity SMD LED boards to ensure they meet minimum efficiency specs.
Our manufacturing processes and corporate governance are BSCI and ISO9001 certified. Our complete product catalog carries CE, ROHS, and UKCA certification for easy customs clearance worldwide.
Pioneering next-generation technologies to increase efficiency and double device lifespan.

Adapting our solar garden light architecture to perform reliably across diverse regional climates.
Different regions present unique challenges for solar garden lights. For northern regions with cold temperatures and short winter days, we use custom charge controllers that work well at sub-zero temperatures. We also opt for high-capacity LiFePO4 batteries, which handle cold weather far better than standard lithium-ion cells.
For tropical monsoon regions and coastal resorts, we use high-salt and humidity-resistant coatings. We build our fixtures with marine-grade 316 stainless steel, anodized aluminum, and UV-stabilized polycarbonate lens assemblies to resist salt-water corrosion, yellowing, and cracking.
In arid, high-temperature areas, we design our housings with thermal venting channels behind the solar panel to dissipate heat. This reduces operating temperatures, protecting the solar cells and battery from thermal degradation.
Expert technical answers to help distributors, retailers, and purchasing managers make informed decisions.
We primarily use Lithium Iron Phosphate (LiFePO4) and Lithium-ion batteries. In optimal conditions, LiFePO4 cells support over 2,000 charge-discharge cycles (approx. 5-7 years of daily use) before capacity drops to 80%. Our built-in overcharge and over-discharge protection circuits prevent cell degradation from voltage spikes or cold weather.
Our designs feature Adaptive Power Management (APM). The built-in microcontroller monitors battery voltage. If charging is limited by rain or clouds, the system automatically dims the LEDs or uses motion sensors to conserve energy. This extends battery run time to 3-5 consecutive nights on a single full charge.
Our standard MOQ starts at 200 units, depending on the product line. We offer full OEM services, including custom housings, custom LED temperatures (Warm White, RGB, Cool White), and dual-mode charging configurations. We also provide custom retail-ready packaging and brown corrugated packaging for B2B distributors.
Every production batch undergoes strict quality control. Our QC process includes integrating sphere tests for luminous flux (lumens), high-pressure water spray booths for Ingress Protection validation (IP65/IP66), thermal shock chambers for extreme temperatures (-20°C to 60°C), and salt spray chambers to test corrosion resistance.
