Explore our specialized portfolio of custom solar lighting engineering, developed to meet international IP65/IP66 and environmental durability standards.
Modern municipal infrastructure planning demands more than simple nighttime illumination. The integration of OEM Solar Street Light 300W systems marks a transition toward intelligent grid independence, maximizing lumen output while minimizing carbon footprints. A robust 300W configuration is widely designated as the industry standard for secondary highways, logistics hubs, municipal parks, and regional arterial roads.
Achieving structural reliability in a self-contained 300W system requires careful alignment of four primary components: high-efficiency monocrystalline PV arrays, premium Lithium Iron Phosphate (LiFePO4) storage, smart maximum power point tracking (MPPT) controllers, and state-of-the-art optical lensing. Rather than relying on simple wattage ratings, professional engineering projects evaluate system efficiency through parameters like effective lumens per watt (lm/W) and depth of discharge (DoD) resilience.
Our OEM factory addresses these critical operational margins by using custom-designed heat sinks and high-transmittance optical lenses. This guarantees that our 300W rated systems maintain continuous, glare-free light distribution pattern profiles (Type II and Type III) and perform reliably even through multiple consecutive cloudy days.
Converting light into energy at a verified efficiency of >22%, our high-purity monocrystalline modules generate power even in low-irradiance or overcast conditions.
Utilizing high-capacity cells with over 3,000 thermal cycles at 80% Depth of Discharge (DoD), ensuring structural safety and stable performance for up to 8-10 years.
Maximum Power Point Tracking algorithms boost harvesting efficiency by up to 30% compared to traditional PWM systems, adapting dynamically to weather changes.
Ningbo Jianheng Import And Export Co., Ltd. (operating alongside manufacturing partner Ningbo Yuancheng Plastic Co., Ltd.) represents the pinnacle of modern solar light manufacturing in China. With a 20-year history of technical innovation, our production capabilities provide a reliable supply chain for global importers, municipal developers, and retail brand owners.
Our modern manufacturing facility covers 10,750 square meters and is equipped with advanced plastic injection molding systems, high-precision surface mounting, automated optical testing arrays, and specialized environmental testing labs. Our production floor features:
We work to eliminate global supply chain risks through strict compliance and testing. Our factory is fully certified under BSCI and ISO9001 standards. Additionally, our products carry CE, ROHS, and UKCA compliance certifications, ensuring easy entry and licensing across North American, European, and UK markets.




Ensuring long-term outdoor stability through strict environmental simulation, raw material verification, and electronic validation protocols.
At our factory, quality control is integrated directly into the assembly process rather than treated as a final check. Each component undergoes strict testing, starting with raw materials: LED chips from recognized suppliers are verified using integrating spheres to ensure luminous efficacy, and battery modules undergo multi-cycle discharge profiles to prevent field failure.
Our products are engineered to withstand extreme climates, including salt spray in coastal zones, intense heat in arid deserts, and sub-zero temperatures. Ingress protection tests (IP65/IP66) are carried out on every product series to prevent dust ingress and moisture damage.
Our QA procedures include automated testing of PCB boards to verify soldering quality, along with high-pressure water spray tests to simulate torrential storms. This comprehensive QA process reduces our return rate to less than 0.18%, providing global procurement directors with peace of mind and stable performance in the field.

Adapting 300W solar street lighting systems to diverse environments, municipal specifications, and local conditions.
Our heavy-duty streetlights feature powder-coated die-cast aluminum frames and stainless-steel hardware, protecting the systems from salt-fog oxidation and ocean spray along coastal arterial roads.
By integrating PIR and microwave motion sensors, the system dims during low-traffic periods, extending runtimes and saving battery energy for stormy weather.
Ideal for off-grid operations where trenching and wiring are cost-prohibitive, providing reliable lighting to improve security and lower installation costs.

A 300W solar street light provides the higher lumen output needed to meet international lighting standards for roadways and parking lots. Lower wattage units (such as 50W or 100W) are suitable for garden pathways or residential fences, but a 300W setup delivers the illumination required for pole mounting heights of 6 to 10 meters, maintaining a wider footprint without losing lux intensity.
LiFePO4 cells are the industry standard for commercial installations. They deliver over 3,000 charge cycles at 80% Depth of Discharge, compared to only 500 to 800 cycles for ternary lithium. They also remain thermally stable at temperatures up to 65°C, preventing fires in hot desert climates and maintaining stable discharge rates in cold environments.
Operating out of Ningbo, China—near one of the world's largest deepwater ports—we offer streamlined logistics. Our design department supports 7-day custom prototyping for housing adjustments, logo placement, controller programming, and tailored battery sizing to meet your municipal bidding requirements.
Our manufacturing plant is certified under ISO9001 and BSCI quality systems. Our lighting systems are tested to meet CE, ROHS, and UKCA standards. We also offer certified IP65/IP66 ingress protection and wind-tunnel performance ratings for high-wind installations.
Yes. Our systems use smart MPPT controllers with dimming programs. When battery voltage drops due to extended rain, the controller reduces the LED output dynamically to maintain basic illumination throughout the night, extending runtimes up to 3-5 consecutive overcast days.
