Solar Lighting

      Proper sizing of photovoltaic components and energy storage is critical for stable off-grid illumination. As a professional solar lighting supplier, we configure our systems based on the specific latitude, solar insolation data, and operational requirements of your target market. Below is the standard technical matrix for our primary product categories.

      To ensure long-term reliability and minimize maintenance overhead for our wholesale clients, our factory utilizes top-tier raw materials and strictly controls the core technical specifications of every component.

Photovoltaic Modules (PV): We utilize Grade-A monocrystalline silicon solar panels with a conversion efficiency exceeding 21.5%. The panels are encapsulated with high-transmittance tempered glass and EVA resin to resist micro-cracking and extreme weather degradation.

Energy Storage (LiFePO4): Unlike standard lead-acid or low-grade lithium-ion alternatives, our default configuration features automotive-grade Lithium Iron Phosphate (LiFePO4) battery packs. These batteries are equipped with built-in BMS (Battery Management Systems) to prevent overcharging, over-discharging, and thermal runaway, offering an operational lifespan of 5 to 8 years.

Optical Design & LED Chips: Integrated with Philips Lumileds or Bridgelux 5050/3030 LED chips, our fixtures are paired with specialized Type II or Type III polycarbonate (PC) batwing lenses. This ensures uniform light distribution, minimal glare, and compliance with strict dark-sky regulations.

      Sourcing directly from a certified solar lighting factory guarantees not only competitive pricing but also verifiable quality assurance. Our manufacturing facility covers 15,000 square meters with a monthly production capacity of 20,000+ units, easily accommodating large-volume wholesale orders and continuous supply contracts.

Every batch of products undergoes a rigorous 6-step Quality Control (QC) protocol before packaging:

Incoming Quality Control (IQC): Cell efficiency testing and battery capacity sorting.

Integrating Sphere Testing: Verifying Color Rendering Index (CRI), Color Temperature (CCT), and total luminous flux.

Salt Spray Testing: 72-hour exposure to ensure the die-cast aluminum housing and powder-coated finish withstand marine and high-corrosion environments.

IP65 / IP67 Immersion Testing: Pressurized water testing to validate the waterproof sealing of the battery compartment and LED modules.

48-Hour Aging Test: Continuous charge/discharge cycling in temperature-controlled dark rooms to eliminate early-stage component failure.

Out-going Quality Control (OQC): Final structural and functional inspection prior to palletizing.

Q: Can you provide IES files for lighting design and simulation?

A: Yes. We provide certified IES files for our entire commercial solar lighting catalog. These files are ready to be imported into DIALux, RELUX, or AGi32 to assist your engineering team in calculating lux levels and spacing optimization for project tenders.

Q: How do your solar lighting systems perform during extended overcast or rainy periods?

A: Our systems are engineered using MPPT (Maximum Power Point Tracking) controllers and appropriately sized LiFePO4 battery banks to guarantee 3 to 5 days of autonomy. We also integrate intelligent dimming profiles (e.g., 100% brightness for 4 hours, 50% for 4 hours, 25% until dawn) to conserve battery capacity during prolonged bad weather.

Q: Do you support SKD (Semi-Knocked Down) or CKD (Completely Knocked Down) shipping?

A: Yes. We regularly supply SKD and CKD wholesale orders. This approach significantly reduces freight volumes, lowers import tariffs in certain jurisdictions, and supports local assembly lines for our long-term B2B distributors.

Q: What is the standard lead time for bulk wholesale orders?

A: For standard specifications, our lead time is 10-15 working days. For OEM/ODM customized orders (including custom housing colors, specific battery capacities, or customized firmware), production requires 20-25 working days after the final drawing approval and deposit receipt.
