1.2 The Name "Nande"

"Nande" (南德) carries a dual meaning. "Nan" (南, South) reflects the company's roots in the southern manufacturing hub of Zhongshan — evoking sunlight, warmth, and brightness. "De" (德, virtue) embodies the business philosophy of "conducting commerce with integrity, establishing character through quality." For 26 years, Nande Solar has held product quality and business ethics as its foundation — a principle that runs through every step from raw material sourcing to finished product shipment.

2. Full Value Chain — The Core Competitive Advantage of a Solar Street Light Factory

There's a saying in the solar street light industry: "To know if a manufacturer is a true source factory, look at whether it makes its own core components."

Many so-called "solar street light manufacturers" are actually assembly operations — purchasing solar panels, lithium batteries, controllers, and LED heads from external suppliers for simple assembly. The problems: component quality depends on outside suppliers, product consistency is hard to maintain, costs pile up through multiple markups, and custom orders are slow to fulfill.

Nande Solar has taken a harder, heavier, but far more valuable path — full value-chain R&D and production.

2.1 Five Core Components — All Self-Manufactured

Nande has built a complete production system covering every core module of a solar lighting system:

(1) Solar Module Production

In-house production lines using monocrystalline and polycrystalline cells, processed through lamination, testing, and aging per standardized procedures. Products are tested to IEC 61215 standards, maintaining strong power output under high temperature, high humidity, and intense UV conditions.

(2) Lithium Battery PACK

Dedicated PACK workshop using industrial-grade LiFePO₄ cells with 2,000+ cycle life. Battery packs are customized per project climate and requirements. Storage-control integrated products achieve IP68 protection, functioning in暴雨 and submerged conditions.

(3) Controller R&D and Manufacturing

Proprietary smart controllers integrating light-sensing, timer control, PIR motion sensing, overcharge/discharge protection, and temperature compensation. Multi-stage dimming is supported — full power for the first hours after dusk, auto-reduced power in the deep night for extended runtime. Nande holds smart street light mobile app software certification for remote parameter configuration.

(4) LED Luminaire Manufacturing

Workshop covering all wattage ranges from 5W to 200W+. High-efficacy LED chips (≥130 lm/W) with professionally designed optical systems that balance road-surface illuminance uniformity with glare and light pollution control.

(5) Pole Processing

Complete lines for cutting, welding, hot-dip galvanizing, and powder coating. Poles use Q235B carbon structural steel in a tapered design (narrower at top), rated for Force 12 typhoons. Dual anti-corrosion protection: hot-dip galvanizing (zinc layer ≥85μm) + electrostatic powder coating — maintaining integrity even in coastal high-salt-spray environments.

2.2 The Real Value of Full Value-Chain Production

Quality control. Every core component is produced in-house from raw material to finished product — no inconsistent external parts. Full process traceability enables rapid root-cause identification when issues arise.

Cost advantage. Eliminating intermediary markups means more competitive factory-direct pricing — especially important for large-volume project buyers.

Flexible customization. Adjusting pole height, source wattage, panel size, or battery capacity is coordinated internally — no bouncing between multiple suppliers.

Stable delivery. ~20,000 sets/month capacity with robust production planning and inventory management ensures on-time delivery even for large orders.

After-sales assurance. Complete lifecycle technical records are maintained. Free repair or replacement during warranty; long-term parts supply and technical support afterward. 446 service centers nationwide ensure response times.

2.3 Equipment and Capacity

The 58,000 m² production base houses multiple specialized workshops:

• Solar module workshop — Automated lamination equipment and power testing systems

• Lithium battery PACK workshop — Spot welders, aging cabinets, capacity grading — multi-step inspection from cell selection to finished pack

• Controller production line — SMT placement, wave soldering, firmware programming, and comprehensive testing

• LED luminaire workshop — Assembly and optoelectronic testing for 5W–200W+ products

• Pole processing workshop — Large plate-rolling machines, automatic welding, hot-dip galvanizing line, and electrostatic spray coating

Monthly capacity: ~20,000 street light sets. Annual revenue: ¥500M+. Among the larger-scale solar street light factories in China.

3. R&D Capability — The Innovation DNA Behind 72 Patents

Twenty-six years in the industry requires more than production scale — it demands continuous innovation.

3.1 Patent Portfolio

As of 2026, Nande Solar has accumulated 72 patents:

• 60 National Patents — Covering LED optical design, lithium battery management systems, pole structural engineering, and smart control algorithms.

5. Project Track Record — From Western Fujian Villages to Middle Eastern Deserts

5.1 Case 1: Zhangyun Village, Shanghang County, Longyan, Fujian

Date: October 30, 2019

Location: Zhangyun Village, Tongxian Town, Shanghang County, Longyan, Fujian Province

Background

Zhangyun Village is a typical Hakka settlement in the mountainous west of Fujian — also a revolutionary base area village. Built along mountainsides with winding roads totaling ~6 km, the village suffered from weak grid infrastructure, unstable voltage, and a chronic lack of public road lighting.

At night, the village roads were pitch black — creating safety hazards for elderly residents and children. For a revolutionary base village, solving the lighting problem wasn't just about safety; it was about improving the village's appearance and advancing the "Beautiful Countryside" initiative.

Traditional grid-powered street lights faced three major obstacles: cabling costs of running kilometers of cable from the nearest transformer; voltage instability (end-of-line voltage often below 180V); and a severe shortage of qualified electricians for maintenance.

Solution

In 2019, the village committee selected Nande Solar after thorough evaluation. The engineering team designed a solution based on the village's specific terrain, solar conditions, and Hakka cultural heritage:

Parameter	Configuration
Quantity	~82 sets
Coverage	~6 km of village roads
Pole Spec	5.5–6m, Q235 steel, hot-dip galvanized
Solar Panel	80–100W monocrystalline high-efficiency
LED Source	15–30W high-brightness, 4000K warm white
Battery	60Ah LiFePO₄
Control	Light-sensing + timer; 5-day autonomy for cloudy weather
Special Design	Hakka cultural elements — traditional patterns on pole decorations

Key advantages:

• Independent power, no wiring — Each unit operates independently, unaffected by grid voltage fluctuations.

• Distributed layout — A single-unit failure doesn't affect others.

• Cultural integration — Pole design incorporates Hakka tulou circular motifs and traditional lattice patterns, harmonizing with the village's architectural heritage.

• Smart control — Auto on/off; deep-night reduced power for extended runtime.

Results

The system went live on October 30, 2019, covering all 6 km of main village roads. The village committee reported: "Choosing solar street lights was the right decision — one investment, long-term use, zero electricity bills, no specialized maintenance needed." Even during extended cloudy periods, the lights maintained normal operation beyond expectations.

As of 2026, these lights have operated stably for over 6 years without batch failures — a successful model for mountain village lighting renovation in western Fujian.

5.2 Case 2: Qatar Solar Street Light Export Project

Region: Qatar (Middle East, Persian Gulf)

Background

Qatar's tropical desert climate features summer temperatures exceeding 50°C, ground temperatures of 70–80°C, intense UV radiation, and frequent sandstorms. As host of the 2022 FIFA World Cup, Qatar undertook massive green infrastructure upgrades, with solar street lights as a key component.

The Qatari side imposed strict requirements on supplier certifications, product quality, delivery assurance, and after-sales service — a comprehensive test of manufacturer capability.

Challenges

Dimension	Requirement
Extreme Heat	Ground temps >60°C; standard lithium batteries degrade rapidly
Sand Ingress	Frequent sandstorms affect panel transparency and luminaire sealing
Intense UV	EVA encapsulant yellows and degrades under strong UV
Quality Standards	Middle Eastern premium market demands exceptional finish and packaging
Salt-Spray Corrosion	Coastal cities face combined heat and salt-spray attack

Solution

Nande executed a comprehensive product customization:

Solar panels: Large-format monocrystalline PERC cells with bifacial technology (rear side captures ground-reflected diffuse light, boosting output 5–15%). Nano-coated self-cleaning glass reduces dust accumulation. UV-resistant encapsulant prevents EVA yellowing; IEC 61215 tested.

Battery system: High-temperature LiFePO₄ with operating range extended to -20°C to +65°C. Aerogel insulation chamber keeps internal temperature 10–15°C below ambient. BMS multi-stage thermal protection: reduces charge current above 45°C, pauses charging above 50°C, disconnects entirely above 55°C.

Luminaire sealing: IP67+ protection with dual-seal interfaces. High-temperature LED chips (≥140 lm/W). Heat sinks enlarged 30% for extreme conditions.

Pole anti-corrosion: Q235B/Q345B steel, 4.0–4.5mm wall thickness, hot-dip galvanizing at 80–100μm + fluorocarbon or high-temp polyurethane topcoat (rated to 120°C) — no fading, bubbling, or peeling at 50°C. All fasteners in 316L stainless steel. Pole rated for Force 12+ winds with reinforced base flange.

Results

First-year failure rate below 0.5% (industry average: 2–3%). All performance metrics met design requirements. Qatar placed multiple follow-up orders totaling 3,000+ sets.

5.3 Lessons from Both Cases

Zhangyun Village and Qatar represent two extremes — domestic rural lighting and overseas premium market requirements — yet the core demand is identical: the product must operate reliably in its specific environment over the long term.

This is exactly what Nande has done for 26 years — providing precision-adapted solutions for each project's geography, climate, and cultural context, rather than a one-size-fits-all approach.
