The Simon Mwansa Kapwepwe International Airport (Ndola Airport) project stands as a testament to what is possible when German-engineered design meets the specific environmental and logistical needs of the African continent. This project involved the deployment of 245 units of high-power solar energy storage systems, custom-configured for the terminal area’s complex road networks. For contractors bidding on similar municipal or commercial projects, this case study provides a technical blueprint for success.
The Strategic Importance of the Ndola Airport Project
Ndola, the industrial hub of Zambia’s Copperbelt, required an airport terminal that matched its economic status. Led by China Aviation Technology International Holding Co., Ltd., the construction of the new terminal building—a 13,319-square-meter facility—demanded an outdoor lighting system that offered 100% autonomy. With Zambia’s abundant solar resources (averaging 5.5 kWh/m²/day), choosing solar LED street lights was the most sustainable and cost-effective path for the terminal’s peripheral roads and parking areas.
Technical Breakdown: Lighting Zambia’s Roads by Design
Every infrastructure project requires a nuanced approach to road safety and light distribution. Our engineering team categorized the airport terminal area into three distinct zones, ensuring that each road type achieved the necessary Lux levels while optimizing energy consumption.
1. Two-Way Two-Lane Roads: Ensuring Consistency and Safety
Most peripheral airport roads fall into this category. The goal here was to provide uniform illumination that facilitates safe traffic flow without over-engineering the system.
- Lighting: 100W Solar Street Lights (High-lumen >160LM/W LED)
- Pole Height: 8 meters (Q235 High-strength Steel)
- Pole Spacing: 30 meters
- Arrangement: Single-sided configuration
- Average Illumination: 16 Lux (Exceeding standard safety requirements for secondary roads)
- Number of Sets: 224 Units
2. Two-Way Four-Lane Roads: High-Intensity Main Arteries
As traffic nears the main terminal building, road widths increase. This requires a bilateral symmetrical arrangement to prevent dark spots in the center of the thoroughfare.
- Lighting: 120W High-Power Solar Street Lights
- Pole Height: 10 meters
- Pole Spacing: 35 meters
- Arrangement: Bilateral Symmetrical
- Average Illumination: 21 Lux
- Number of Sets: 9 Units
3. One-Way Three-Lane Roads: Precision Optics for High Throughput
The departure and arrival ramps require high-visibility lighting to assist drivers navigating complex terminal loops.
- Lighting: 120W Solar Street Lights
- Pole Height: 10 meters
- Pole Spacing: 30 meters
- Average Illumination: 23 Lux (Optimized for high-density pedestrian and vehicle interaction)
- Number of Sets: 12 Units
The Engineering Edge: Why ClodeSun Components Thrive in Zambia
The success of the Ndola project for over a year of operation is not a coincidence. It is the result of rigorous component selection. Engineering contractors must understand that not all solar lights are created equal, especially when exposed to the high heat and dust of Sub-Saharan Africa.
A-Grade LiFePO4 Battery Technology
Zambia’s climate can be punishing for traditional lead-acid or low-quality ternary lithium batteries. ClodeSun utilizes A-Grade LiFePO4 (Lithium Iron Phosphate) batteries. These cells are known for their thermal stability and 6,000+ cycle life. By using this technology, we ensure the lights maintain 100% performance even after years of deep discharge. For a deeper dive into battery chemistry, read our guide on the four kinds of batteries for solar street lights.
Smart MPPT Controllers and High-Efficacy LEDs
Every watt counts. Our systems utilize Maximum Power Point Tracking (MPPT) controllers which increase charging efficiency by up to 30% compared to standard PWM controllers. This is critical during Zambia’s rainy season when cloud cover can limit PV intake. Combined with our high-efficacy LED beads (>160 Lumens per Watt), we produce more light with less energy, allowing for smaller, more cost-effective battery configurations without sacrificing brightness.
Overcoming Logistical Hurdles in International Procurement
Construction projects of this scale are often complicated by the distance between the manufacturer and the site. The Ndola project faced long transportation cycles and significant time differences. For regional distributors, the total landed cost of a product is often dictated by shipping volume. This is why ClodeSun pioneered the foldable all-in-one solar street light design.
By reducing the shipping volume of our fixtures, we allow contractors to fit more units into a single container, drastically lowering freight costs and reducing the risk of transit damage. At the Ndola site, our “Plug-and-Play” design meant that installation could be carried out by local labor with minimal specialized training, further reducing the overall project cost.
Addressing Energy Shortages and Environmental Policy
Zambia’s move toward renewable energy is supported by international bodies such as the World Bank and various “One Belt, One Road” initiatives. By installing 245 units of solar lighting, the airport project saves thousands of kilowatt-hours annually and reduces dependency on the grid. This aligns with global ESG (Environmental, Social, and Governance) standards, making ClodeSun products an ideal choice for contractors working on funded infrastructure bids.
Furthermore, the incorporation of an intelligent monitoring system allows for remote management of the lighting assets. This reduces the need for on-site inspections, which is a major value add for municipal owners who want to minimize long-term maintenance staff costs.
Conclusion: A Blueprint for B2B Partnership
The Ndola Airport project is more than just a lighting installation; it is a successful navigation of policy, culture, and technical engineering. ClodeSun has proven that by focusing on high-quality LiFePO4 storage, MPPT efficiency, and optimized road design, we can deliver world-class infrastructure even in the most challenging environments.
Whether you are a regional distributor looking to stock reliable all-in-one solar street lights or an engineering contractor preparing a government bid, ClodeSun offers the technical support and design innovation required to win. Our 13 years of experience in the industry, backed by 280+ patents and certifications including IEC, CE, and RoHS, make us the preferred partner for solar lighting in Africa and beyond.

Frequently Asked Questions: Solar Lighting in Zambia
1. Why is LiFePO4 the preferred battery for Zambian solar projects?
Zambia experiences high daytime temperatures. Standard lithium batteries can suffer from thermal runaway or rapid degradation in such heat. LiFePO4 batteries are safer, have a higher temperature threshold, and offer up to 10 years of service life, making them the most cost-effective choice for long-term infrastructure.
2. Can these solar street lights withstand Zambia’s heavy rainy season?
Yes. Our systems are designed with IP67-rated waterproofing and our MPPT controllers ensure that the system continues to charge efficiently even during periods of heavy cloud cover. Our standard configurations include 3-5 days of autonomy, meaning the lights will stay on even if there is zero sunlight for nearly a week.
3. What is the typical installation time for an all-in-one solar light at an airport?
Because of our “Plug-and-Play” design, the assembly of the fixture onto the pole takes approximately 5-10 minutes. The longest part of the process is the foundation and pole erection. Compared to grid-tied lighting, solar installation is about 60% faster because it eliminates the need for trenching and cabling.
4. Does ClodeSun provide IES files for lighting simulations in project bids?
Absolutely. We provide full technical documentation, including IES files, to help engineering contractors perform Dialux simulations. This ensures that the proposed lighting layout meets the Lux and uniformity requirements specified in the tender documents.
5. How does the foldable design help in reducing international shipping costs?
Traditional all-in-one solar lights are bulky and long, leading to high “dead space” in shipping containers. ClodeSun’s foldable design allows the solar panels to be packed separately or folded, reducing the volume of each unit by up to 40%. This allows for more units per container, significantly lowering the landed cost for distributors.
6. What maintenance is required for the Ndola Airport solar lights?
Maintenance is minimal. We recommend a visual inspection once a year to ensure the solar panels are free of heavy dust or debris. Because we use brushless DC motors (in some models) and long-life LED chips, there are no bulbs to change or wires to repair for at least 8-10 years.
