Explore our primary array of high-efficiency outdoor solar lighting systems, engineered for resilience and architectural integration.
As the international community accelerates its path toward net-zero emissions, public, industrial, and commercial infrastructure sectors are undergoing a massive transformation. High on the priority list of municipal planners, civil engineers, and warehouse logistics developers is the transition from conventional, grid-tied High-Pressure Sodium (HPS) or Metal Halide lighting to Custom Powerful Solar Street Lights. The reasons extend beyond simple carbon footprints; they encompass complete grid independence, elimination of trenching and cabling costs, and protection against escalating electricity rates.
Modern commercial street lighting demands extreme luminous efficacy, prolonged autonomy during continuous rainy days, and absolute operational reliability. Historically, solar lighting was perceived as a decorative, low-lumen alternative best suited for gardens. However, through aggressive R&D investments in high-density Monocrystalline Silicon photovoltaics, smart Maximum Power Point Tracking (MPPT) charge controllers, and automotive-grade LiFePO4 (Lithium Iron Phosphate) energy storage systems, modern solar street lights deliver illumination levels exceeding 20,000 lumens. This easily matches and surpasses traditional grid systems while operating completely off-grid.
Utilizing high-conversion-rate Monocrystalline panels (up to 23.5% efficiency) that harvest energy even in low-light and overcast conditions.
Equipped with smart thermal management BMS, delivering over 3,000 deep charge cycles for a lifespan exceeding 8-10 years.
Real-time tracking of current-voltage curves to optimize charging current by up to 30% compared to traditional PWM systems.
Ningbo Jianheng Import And Export Co., Ltd. (operating in conjunction with Ningbo Yuancheng Plastic Co., Ltd.) is a leading, world-class solar lighting manufacturer based in Ningbo, China. With a proud history spanning 20 years in the industry, our company has grown to become one of the most reliable suppliers of high-performance off-grid lighting solutions globally.
As a true pioneer in the solar energy sector, we have committed ourselves to providing innovative, premium-quality products to international business partners. Our modern manufacturing facility covers a vast area of 10,750 square meters, packed with highly automated machinery and advanced testing equipment. We boast a dedicated workforce of 105 skilled technicians and production workers, supported by 15 administrative and customer support professionals, ensuring every project is delivered on schedule, regardless of scale.
At Ningbo Yuancheng Plastic Co., Ltd., quality is not just a slogan; it is the cornerstone of our manufacturing philosophy. We strictly inspect all incoming raw materials, from the purity of the solar cells to the density of the die-cast aluminum housings. Our quality control team runs real-time diagnostic checks throughout production, including IP65/IP66/IP67 waterproof chamber testing, wind tunnel simulation, and spectrophotometer evaluations for chromaticity and lumen maintenance.
Our operations are fully certified under BSCI and ISO9001 systems. For international markets, our products hold complete CE, ROHS, and UKCA certifications, ensuring smooth customs clearance and compliance with strict regional regulations. We specialize in B2B OEM and ODM custom orders. Recognizing that each geographical location has distinct solar irradiance and municipal codes, we offer a 7-day fast proofing service. This allows engineering firms, distributors, and municipal contractors to obtain customized physical prototypes and precise, competitive quotes quickly.
To successfully replace grid-based lighting, a solar street light must be designed with high-efficiency energy capture and smart power management. Our engineering roadmap focuses on three main hardware components: the PV module, the storage cell, and the LED emitter array.
Low-cost solar lights often use polycrystalline panels, which suffer from lower efficiency (15%–17%) and degrade faster. Ningbo Jianheng uses premium monocrystalline silicon wafers with a 21%–23.5% solar-to-electric conversion rate. This ensures the batteries charge even on short winter days or during heavy rain and overcast weather.
Traditional lead-acid or standard lithium-ion batteries fail under extreme temperatures. Lead-acid batteries degrade rapidly in hot climates, while standard lithium-ion options risk thermal runaway. We use LiFePO4 battery chemistry. These cells operate reliably from -20°C to 65°C and feature built-in smart Battery Management Systems (BMS). This prevents overcharging, deep discharging, and overheating, extending the system's operational life to over 10 years.
Lumen output depends on both LED wattage and optical lens design. Our street lights use high-efficiency SMD 5050 / 3030 LED chips that deliver up to 180 lm/W. With custom batwing optical lenses, light is distributed evenly across pathways without wasting energy on adjacent empty areas. This matches municipal lighting standards while keeping energy consumption low.
Our solar street lights combine smart motion sensing and custom power profiles. Using passive infrared (PIR) and microwave radar sensors, the lights operate at 100% brightness when pedestrian or vehicle activity is detected, dropping to a 30% eco-mode when the area is clear. This smart management extends battery autonomy, keeping the light running even after 5-7 consecutive days of rain.
Manufacturing high-output solar street lights requires a reliable supply chain. Located in Ningbo, a global industrial hub, our factory has direct access to the raw materials and electronics needed for production. This allows us to keep lead times short and pricing competitive.
Ningbo is home to some of the world's most advanced deep-water port infrastructures. This lets us source components locally—such as micro-controllers, specialized optics, structural steel brackets, and high-purity aluminum housings—and ship finished goods to international markets quickly. It eliminates the logistical delays common in landlocked manufacturing regions, ensuring our global distributors, contractors, and retail partners receive their shipments on time.
We supply a diverse selection of high-durability solar lighting fixtures, including solar garden lights, solar street lights, solar flood lights, solar bug zappers, and solar ground lights. Each model is engineered for energy efficiency, durability, and easy installation. They are ideal for public parks, municipal roads, commercial parking lots, industrial perimeters, and residential developments.

Industrial, commercial, and municipal sites have unique lighting requirements. Custom solar street lights provide tailored solutions across a variety of demanding applications:
Connecting remote roads to the main power grid is often cost-prohibitive. High-output solar street lights provide an efficient alternative, eliminating the need for expensive copper wiring. Installed along highway exits, rural intersections, and secondary roads, these systems improve driver safety without ongoing energy costs.
Coastal installations face harsh conditions, including high winds and corrosive saltwater. Our custom solar lights feature hot-dip galvanized coating, powder-coated aluminum housings, and IP67-rated enclosures. Designed to withstand wind speeds up to 60 m/s, they provide reliable lighting along beachfronts and marine ports.
Logistics parks and warehouse yards require continuous perimeter lighting for security. By replacing traditional grid-tied fixtures with off-grid solar street lights, facilities reduce electricity costs and maintain security illumination during grid failures or blackouts.
Standard solar lights often fail in extreme climates. We customize our systems for specific environments, using insulation jackets for sub-zero climates and advanced thermal heatsinks for desert regions. This ensures the solar cells and batteries operate reliably regardless of weather conditions.
