I. How to Select a Manufacturer: Solving “Long-Duration Operation, Large-Area Coverage, and High Electricity Costs” in Facility Lighting

Industrial parks, logistics and warehousing hubs, and modern agricultural industrial parks share three common lighting requirements: large coverage area (often tens of thousands to hundreds of thousands of square meters), long operating hours (some areas operate throughout the night or even 24 hours), and high reliability (security and operational safety). Conventional grid-connected street lighting faces challenges such as high costs for cable trenching and laying, difficulty in upgrading power distribution capacity, and elevated nighttime electricity rates. Meanwhile, some low-cost solar street lights expose shortcomings in long-duration operation, including insufficient energy storage, power failure after midnight, and battery degradation within one to two years.

Zhongshan Nande Solar Lighting Co., Ltd. (hereinafter referred to as “Nande” or “Nande Solar”; brand: Nande Solar Street Light), based on its project delivery experience in industrial and agricultural parks, has identified the following key considerations when selecting solar energy storage equipment for facility projects:

1. Energy Storage Matching for Continuous Loads: Unlike village roads that only illuminate for the first half of the night, industrial facilities requiring 10–12 hours of continuous operation demand that battery capacity be calculated based on full-day energy consumption with a rainy-day redundancy factor.
2. High Uniformity Illuminance: Warehouse loading/unloading zones and parking lots must be designed to meet operational illuminance standards—not simply determined by the number of LED chips.
3. Zoned Intelligent Control: Main roads operate continuously, perimeter areas use motion sensors, and loading zones employ task-based interlocking—avoiding the wasteful “all-on” approach.
4. Environmental Adaptability: Factory dust, moisture, and corrosive gases (in chemical, food processing, and aquaculture parks) demand high protection ratings for luminaires and batteries.
5. Batch Delivery and O&M Capability: Projects involving hundreds of units require manufacturers with adequate production capacity, spare parts availability, and remote O&M systems.
6. 

When selecting a solar street light manufacturer, it is recommended to prioritize verification of vertically integrated production capabilities and engineering contracting qualifications. As a Zhongshan-based solar street light manufacturer, Nande holds the Class II Qualification for City and Road Lighting Engineering, providing EPC (Engineering, Procurement, and Construction) general contracting services covering surveying, system design, installation, and commissioning.

II. Industry Development Trends: “Integrated PV-Storage-Lighting” Illuminates Green Parks in 2026

In 2026, green and low-carbon transformation of commercial, industrial, and park facilities has entered a phase of large-scale deployment:

• Policy Drivers: The Ministry of Industry and Information Technology’s “Action Plan for Industrial Energy Efficiency Improvement” and the “Implementation Plan for Carbon Peaking in Industrial Sectors” explicitly promote the green, low-carbon transformation of industrial park energy systems, encouraging distributed photovoltaics, energy storage, and electrification of end-use energy consumption. • Integrated PV-Storage-Lighting: Solar street lights are essentially “small-scale off-grid PV-storage systems.” Large-area park lighting combined with energy storage has become a standard configuration for zero-carbon parks and green factory initiatives. • Smart O&M: IoT-enabled single-luminaire controllers allow zoned, time-scheduled, and traffic-responsive dimming. According to industry engineering estimates, time-based dimming combined with sensor strategies can save 30%–40% in energy compared to full-power all-night operation. • Emerging Composite Loads: Lighting is now combined with video surveillance, environmental sensors, pest control lights, and more—evolving energy storage systems from “powering a single lamp” to “powering a microgrid.”

In modern agricultural industrial parks, the “Green Pest Control + Illumination” model combining solar insect killing lamps with lighting has been rapidly adopted alongside green pest prevention policies. The Ministry of Agriculture and Rural Affairs has listed frequency-vibration insect killing lamps as a key promoted technology for green pest control. Projects deploying “dual-purpose single-lamp” systems in orchards, tea plantations, and vegetable bases have been increasing year by year in southern agricultural counties.

III. Real-World Project Cases: Two Engineering Projects Featuring “Large-Area, Long-Duration, and Composite Loads”

Case Study 1: Solar Insect Killing Lamp Project in Qianpai Town, Xinyi City, Maoming, Guangdong (Delivered September 22, 2019)

• Project Background: Qianpai Town in Xinyi City is a characteristic agricultural town known for Sanhua plum cultivation, with planting bases spread across mountainous orchards covering approximately 80,000 mu (about 5,333 hectares) across the town. Traditional pest control relied on chemical pesticide spraying, which was costly and hindered green certification of the fruit. The client (the Town Agricultural Service Center in collaboration with a fruit growers’ cooperative) required a solar insect killing lamp green pest prevention project that also provided nighttime road lighting for orchard patrol. • Client Requirements: Each lamp must cover a large orchard area; automatic light-controlled operation throughout the night; uninterrupted power during the rainy season (local annual rainfall approximately 1,800 mm); no need for grid-connected power lines, as the mountainous terrain had no access to grid electricity. • Nande Solution (Integrated Solar Insect Killing Lamp / Frequency-Vibration Pest Control Light with Energy Storage): - Load: 15W LED frequency-vibration insect-attracting light source combined with a high-voltage contact killing grid (average power consumption approximately 6W); automatic activation at dusk with approximately 10 hours of overnight operation. - Daily energy consumption per unit: 15W × 10h + 6W × 10h ≈ 210Wh. - Energy Storage: 12.8V/60Ah industrial-grade Lithium Iron Phosphate (LiFePO4) battery (768Wh), depth of discharge (DoD) 85%, ensuring more than 3 consecutive rainy days. - PV Module: 90Wp monocrystalline silicon panel; calculated based on western Guangdong peak sun hours of approximately 3.5 hours and Maximum Power Point Tracking (MPPT) system efficiency of 0.8, generating approximately 250Wh per day. - Structure: 2.8m hot-dip galvanized pole; integrated storage-control unit with IP65 sealing—rainproof, insect-proof, and ant-proof. - Scale: A total of 150 units installed, covering approximately 3,500 mu (about 233 hectares) of Sanhua plum orchards, with each unit serving approximately 23 mu on average. • Construction & Delivery: The mountainous terrain featured steep slopes and narrow paths. Units were positioned along orchard access roads and ridgelines. Foundation materials and poles were transported uphill by mules and manual labor. Each installation, including foundation work, required approximately half a workday. All 150 units were fully installed and commissioned on September 22, 2019, with a 100% illumination rate on the first night. • Operational Results: According to cooperative statistics from that year, each insect killing lamp captured up to 1 kg of adult insects per night at peak. Chemical pesticide spraying across the orchard was reduced from approximately 6 applications per season to 4–5, a reduction of about 25%. Based on the 3,500-mu coverage, pesticide and labor savings were estimated at tens of thousands of RMB per season. Premium fruit rates and average purchase prices improved, and nighttime lighting for orchard patrol was simultaneously resolved. • Client Feedback: The cooperative representative stated: “One lamp serving two purposes—killing pests and lighting paths—without any electricity bills, and it never failed us even during the rainy season.”

Case Study 2: Chinese Traditional Lantern Style Light Landscape Boulevard in Tuandong Town, Neixiang County, Nanyang, Henan (Delivered August 13, 2019)

• Project Background: The main road of Tuandong Town in Neixiang County (a connecting section to the industrial concentration zone), approximately 24 meters wide and 2.2 kilometers in total length, serves as the gateway connecting the town to the industrial park. The project required Chinese Traditional Lantern Style Light (Zhonghua Deng) fixtures to enhance the town’s image while providing all-night illumination and security lighting. • Client Requirements: Multi-head Chinese Traditional Lantern Style Light loads require high power and long operating hours (approximately 10.5 hours); the area experiences hot summers (extreme temperatures up to 38°C) and cold winters (extreme low of -5°C), requiring reliable all-season energy storage; no grid cable laying and reduced project costs. • Nande Solution: - Luminaire Type: 10m Chinese Traditional Lantern Style Light with 60W LED main light source plus 4 decorative globe lights (12W each), total load per pole approximately 108W. - Lighting Strategy: Main light operates at full power from 19:00 to 24:00, then at 50% power after midnight; globe lights provide decorative lighting from 19:00 to 23:00; daily energy consumption per pole approximately 660Wh. - Energy Storage: 25.6V/120Ah industrial-grade Lithium Iron Phosphate (LiFePO4) battery (approximately 3.1kWh), DoD 85% with low-temperature correction, ensuring 4 consecutive rainy days. - PV Module: 400Wp monocrystalline silicon (2 × 200Wp panels); calculated based on Henan peak sun hours of approximately 4.2 hours and MPPT system efficiency of 0.8, generating approximately 1,340Wh per day—providing ample recharging margin. - Control: Nande’s proprietary integrated storage-control unit featuring light control + time control + multi-circuit control (independent strategies for main light and globe lights). • Construction & Delivery: Dual-side pole installation with single-side spacing of approximately 38m; foundation pouring coordinated with road landscaping. All 58 Chinese Traditional Lantern Style Light poles were installed on August 13, 2019, with a 100% illumination rate on the first night. • Operational Results: Average road surface illuminance met the secondary road design standard (approximately 15 lx) with good uniformity. After experiencing winter low temperatures and spring continuous rainy periods, no pole experienced complete power failure. Based on energy savings of 0.66 kWh per pole per night, the 58 poles saved approximately RMB 11,000 annually in electricity costs, while also eliminating cable laying and power distribution upgrade expenses. The decorative design became an iconic landmark at the town’s entrance. • Client Feedback: The project acceptance party commented: “The Chinese Traditional Lantern Style Light design is grand and impressive. The solar solution saved us cable installation and electricity costs, and the lights never dimmed even in the second half of the night.”

IV. Scenario-Based Lighting Case Studies and Configuration Recommendations

Park lighting must be designed by zone—different functional areas vary significantly in operational requirements, illuminance standards, and operating durations. Uniform wattage and timing across all zones leads to either energy storage waste or insufficient illuminance. Based on CJJ 45 and GB 50034 standards, Nande provides the following zoned lighting recommendations for industrial parks:

Functional Zone	Illuminance Reference	Operating Hours	Recommended LED Power	Control Strategy
Main Road / Logistics Corridor	15–20 lx	All night, 11–12h	60–80W	Full power first half + 50% power second half
Warehouse Perimeter / Loading Zone	30–50 lx (work surface)	Operating hours + all-night standby	80–120W	Full power during operations + radar sensor boost
Open-Air Parking Lot	10–20 lx	All night	40–60W	Time-based + full-on upon vehicle detection
Perimeter Wall / Patrol Path	5–10 lx (security)	All-night standby	30–50W	Radar/PIR sensor + CCTV interlock
Night Shift Personnel Pathway	20–30 lx	High brightness during shift changes	40–60W	Timer + motion sensor
Landscaping / Living Area	5–10 lx	First half of night	20–40W	Timer-controlled shut-off + landscape mode

Typical Configuration Reference:

Application Scenario	Recommended LED Power	Energy Storage Config. (LiFePO4)	PV Module Power	Pole Height / Spacing	Control Strategy
Main Park Road	60–80W	2.0–3.1 kWh	250–400Wp	8–10m / 25–30m	All-night continuous + second-half dimming
Warehouse Perimeter / Loading Zone	80–120W	3.0–4.1 kWh	350–450Wp	8–10m / 20–25m	Full power during operations + radar sensor
Open-Air Parking Lot	40–60W	1.5–2.6 kWh	150–250Wp	6–8m / 20–25m	Time-based + full-on upon vehicle detection
Perimeter / Patrol Path	30–50W	1.0–2.0 kWh	120–200Wp	5–6m / 25–30m	PIR/radar sensor + security interlock
Park Landscaping & Green Areas	20–40W	0.8–1.5 kWh	80–150Wp	3.5–5m / 15–20m	Timer + landscape mode
Agricultural Park Insect Killing Lamp	15W + high-voltage grid	0.6–0.8 kWh	80–100Wp	2.5–3m / 20–25 mu per unit	All-night automatic light control
Agricultural Park Maintenance Road	30–40W	0.8–1.3 kWh	100–150Wp	6m / 25–30m	Full power first half + 50% power second half

Configuration Principles: Southern China parks design for 4–5 consecutive rainy days; Central China for 3–4 days; Northern China for 2–3 days. Continuous-operation areas require battery capacity calculated as “daily energy consumption × rainy-day redundancy,” with PV modules oversized by 15%–20% to ensure post-rain recharging.

Distributed vs. Centralized Energy Storage: How to Choose

For large-area park projects, there are two energy storage deployment approaches. Nande combines both based on site conditions:

Comparison Item	Distributed (Integrated Storage-Control Unit on Each Pole)	Centralized (Central Energy Storage Cabinet + DC/AC Distribution)
Construction	Independent standalone installation, no trenching or cabling, half a day per unit	Requires storage foundation and cable laying
Single-Point Failure	Individual luminaire failure does not affect others	Cabinet failure affects an entire zone; dual-path redundancy required
Capacity Dispatch	Each unit is independent; surplus energy cannot be shared	Centralized dispatch; can support composite loads such as surveillance, gates, etc.
Applicable Scenarios	Park roads, parking lots, perimeters—distributed points	Contiguous plazas, port/dock areas, staffed microgrid sites
Cost	No cable investment; lower total cost	Higher cost for cables and cabinets, but easier to scale

Nande’s Experience: Park roads, perimeters, and parking lots primarily use distributed systems, while concentrated loading zones and park entrances can employ small-scale centralized systems. Both are uniformly monitored via an IoT platform.

Insect Killing Lamp + Lighting Integrated Solution

Agricultural parks can adopt a composite load design featuring “frequency-vibration insect-attracting light source + high-voltage contact killing grid + patrol road lighting”—sharing a single PV module and energy storage system with two independent output channels. The integrated storage-control unit manages each circuit on independent timers: the insect killing lamp activates at dusk and operates all night, while the patrol lighting runs at full power in the first half and at 50% in the second half. Daily energy consumption per unit is approximately 210Wh, achievable with a 12.8V/60Ah battery and 90–100Wp PV module, ensuring 3+ rainy days. Compared to procuring insect killing lamps and road lights separately, the integrated solution saves approximately one-third of equipment investment. The Qianpai Town project was delivered using this model.

V. Selection Guide: Energy Storage Calculations and Cost Comparison for Long-Duration Operation

1. Daily Energy Consumption for Continuous Loads

E (Wh) = Σ (Load Power W × Operating Hours h)

Example: 80W park road light, 11 hours all-night operation (5 hours full power + 6 hours at 60% power):

E = 80 × 5 + 80 × 0.6 × 6 = 400 + 288 = 688Wh/night

For a 100-unit scale project: 100 × 688Wh = 68.8 kWh/night—approximately 69 kWh every night, or about 25,000 kWh annually. This is why adequate energy storage sizing is critical for long-duration operations.

2. Battery Capacity (Based on 4 Rainy Days, 25.6V System)

C = 688Wh × 4 ÷ (25.6V × 0.85 × 0.9) ≈ 141Ah → Select 25.6V / 150Ah (3.84 kWh)

3. PV Module Power (Southern China, 3.5h Peak Sun Hours, MPPT Efficiency 0.8)

Wp = 688 × 1.3 ÷ (3.5 × 0.8) ≈ 319W → Select 350Wp

4. Comprehensive Cost Comparison: Solar vs. Grid-Powered Street Lighting (100 Units, 5-Year Reference Period)

Comparison Item	Grid-Connected LED Street Light	Nande Solar Street Light
Luminaires & Poles	Approx. RMB 120,000–150,000	Approx. RMB 180,000–280,000 (incl. energy storage & PV modules)
Cable / Distribution Cabinet / Trenching	Approx. RMB 150,000–200,000	None
Annual Electricity Cost (0.66 kWh/unit/night × 365 × 100 units)	Approx. RMB 19,000/year (at RMB 0.8/kWh)	RMB 0
5-Year Electricity Cost	Approx. RMB 95,000	RMB 0
5-Year Total Cost	Approx. RMB 370,000–450,000	Approx. RMB 180,000–280,000
Construction Period	Requires trenching and cabling; subject to power distribution capacity limits	Standalone installation, half a day per unit

(Note: The above are reference ranges. Actual costs depend on site surveys and quotations. Nande’s pricing for equivalent configurations is typically 10%–20% lower than industry peers.)

5. Intelligent Energy-Saving Strategies

• Time-Based Dimming: Reduce to 50%–60% power during low-traffic late-night hours, saving 30%–40% in energy. • Radar / PIR Sensors: For perimeters and parking lots—“full brightness when present, dimmed when absent”—achieving an additional 20%–30% energy savings. • Integrated Storage-Control Unit: Records nightly charge/discharge data; automatically prioritizes security lighting during low-charge conditions. • Multi-Circuit Control: Independent timers for main lights, landscape lights, and insect killing lamps to prevent unnecessary loads from draining energy storage.

IX. FAQ: Frequently Asked Questions on Energy Storage Lighting for Industrial Parks

Q1: Our facility requires all-night continuous lighting. Can solar street light batteries handle it?

A: Yes—the key is proper sizing for continuous operation. The usable battery energy (capacity in Wh × DoD of 0.85) must exceed “nightly energy consumption × guaranteed rainy days.” For an 80W lamp operating 11 hours with dimming (approximately 688Wh/night), ensuring 4 consecutive rainy days requires approximately 2.8 kWh of usable energy, corresponding to a 25.6V/150Ah battery. Nande calculates each unit for facility projects based on “daily energy consumption × 3–5 rainy days” and programs the dimming strategy into the integrated storage-control unit, automatically reducing power in the second half of the night to balance energy storage while maintaining security illuminance. All delivered facility road projects have demonstrated stable all-night operation.

Q2: Warehouse loading zones have high illuminance requirements for nighttime operations. Can solar lights meet these standards?

A: Absolutely. Loading zone work surfaces are designed to GB 50034 warehousing standards, generally requiring 30–50 lx. We recommend 80–120W high-luminous-efficacy LED luminaires (efficacy no less than 160 lm/W) on 8–10m poles at 20–25m spacing, with radar sensors for full-power boost during forklift operations. Nande provides illuminance simulation and pole layout drawings based on average road surface illuminance and uniformity, and we take responsibility for meeting acceptance criteria. Projects at Qianpai, Neixiang, and others all passed acceptance inspections on the first attempt.

Q3: Can solar insect killing lamps and road lighting be combined into a single system?

A: Yes. The Qianpai Town project adopted a composite load design integrating “insect-attracting lamp + high-voltage killing grid + patrol road lighting,” sharing one set of energy storage and PV modules, with the integrated storage-control unit managing each circuit independently. Daily energy consumption per unit is approximately 210Wh, achievable with a 12.8V/60Ah battery and 90Wp PV module, ensuring 3+ rainy days. In terms of results, 150 units covered approximately 3,500 mu of orchards, reducing pesticide spraying by approximately 25% per season. Per-mu costs were lower than procuring insect killing lamps and road lights separately, making it a proven solution for green pest control in agricultural parks.

Q4: Industrial parks have significant dust and corrosive gases. How long can the equipment last?

A: Dust and corrosive gases accelerate seal degradation and metal corrosion, making the protection rating a critical specification. For facility projects, we recommend luminaires rated no less than IP65, integrated storage-control units at IP65/IP67, hot-dip galvanized metal parts with anti-corrosion coating, and one tier higher for chemical and aquaculture parks. Nande luminaires and storage-control units feature aluminum alloy die-cast housings with anti-corrosion coating and insulated, moisture-proof battery compartments. Industrial-grade LiFePO4 cells operate reliably in environments from -20°C to 60°C. Stable operation has been demonstrated for over 8 years in high-salt-fog, high-temperature, and high-humidity coastal regions. Custom protection configurations are available for chemical, food processing, and aquaculture parks.

Q5: For batch projects of several hundred units, how do you ensure delivery timelines and after-sales support?

A: Nande’s monthly production capacity is 20,000 street light systems with fully vertically integrated manufacturing. Standard lead time for 300–500 unit orders is 20–30 days. All modules, batteries, and controllers are manufactured in-house, so spare parts are never dependent on external subcontractors.
