Engineered to operate reliably under high ambient temperatures and desert sandstorms across Namibia, from Walvis Bay to the Kunene Region.
Namibia is characterized by some of the highest solar irradiance levels globally, averaging between 3,000 and 3,600 hours of sunshine per year. However, translating this extreme solar resource into reliable public and industrial illumination poses unique engineering challenges. Traditional all-in-one solar streetlights often suffer from thermal choking due to high ambient temperatures, which can exceed 45°C in the interior regions like the Kalahari and Namib deserts. Furthermore, coastal areas such as Walvis Bay and Swakopmund face highly corrosive salt-laden mist combined with fine desert dust that accumulates rapidly on horizontal surfaces, blocking sunlight and reducing panel output.
This is where Wuxi Zeteo Light’s split solar streetlights excel. By separating the solar panel, the LiFePO4 battery, and the LED luminaire, our designs allow for optimal orientation of the solar array (maximizing yield based on NamPower grid-tie criteria) while placing the sensitive lithium battery assembly and controller either at the base of the pole or in a shaded housing directly under the panel. This split configuration lowers the operating temperature of the battery pack, extending its life cycle up to 6,000 charges and preventing premature system failures common in integrated designs.
Mining operations in the Erongo region (particularly uranium and gold extraction) require robust, 24/7 security illumination along perimeter fences, access roads, and processing yards. Grid expansion in these remote sectors is financially prohibitive, costing up to $15,000 USD per kilometer. Similarly, growing municipal zones in Windhoek, Rundu, and Oshakati face rising grid maintenance costs and load shedding. Our high-power split systems offer an autonomous, carbon-neutral solution that eliminates continuous operational costs and guarantees high-uptime lighting independent of the national grid.
For international EPC (Engineering, Procurement, and Construction) contractors and domestic Namibian public works departments, procurement decisions must balance initial capital expenditure (CAPEX) with long-term operational expenditure (OPEX). Poor-quality components lead to high maintenance costs due to battery replacements, faded optical lenses, and failed charge controllers. Enterprise sourcing requirements demand deep documentation, certified testing records, and verified manufacturer capacity.
Wuxi Zeteo Light addresses these rigorous compliance matrices directly. Our raw material supply chains are traceably documented, using tier-1 A-grade monocrystalline silicon solar cells, high-lumen Philips or Bridgelux LED chips, and premium LiFePO4 cells. By working directly with a manufacturer that possesses integrated 3GW PV and 1GWh battery production capacities, buyers bypass intermediate trading margins, secure verified warranties, and receive direct custom engineering support (OEM/ODM) to adjust pole brackets, panel tilts, and programmed dimming profiles.
Our engineering team designs complete site-specific simulations including Dialux lux plans, wind load assessments for desert regions, and solar yield calculations.

Wuxi Zeteo Light Co., Ltd. is a leading high-tech enterprise dedicated to the research, development, and manufacture of advanced solar photovoltaic products and high-capacity energy storage systems. Our production system is fully automated and meets international quality standards. The annual capacity of our photovoltaic modules is 3GW, and the annual capacity of our energy storage batteries exceeds 1GWh. This scale ensures that we can support major public infrastructure projects in Namibia and around the world, delivering consistent product quality on schedule.
By managing a vertical industrial chain—from monocrystalline cell engineering and advanced PV module encapsulation to smart battery pack assembly (BMS integration) and luminaire design—we maintain strict quality control at every stage. We use automated EL (Electroluminescence) testing to spot micro-cracks before lamination, and run 72-hour high-temperature aging chambers to verify performance in challenging environmental conditions, including desert climates.
Deploying solar infrastructure in Namibia requires adapting to localized weather profiles. System components are exposed to high UV indexes (which degrade standard plastics), coastal humidity, and desert wind loads. To address these factors, Wuxi Zeteo’s split solar street light design includes targeted engineering updates:
Lithium iron phosphate (LiFePO4) batteries perform best when their temperature is kept stable. Instead of placing the batteries directly under the hot solar panels, Zeteo’s split configurations position them in insulated ground boxes or pole-mounted shading enclosures. This configuration reduces direct solar heating, keeping the cells within their optimal operating range and supporting a 10-year service life.
Fine desert sand in regions like Namib-Naukluft can settle on solar modules, reducing power output. To address this, Wuxi Zeteo offers customized mounting brackets with tilt options up to 35 degrees to promote natural self-cleaning during rain or wind. In addition, our solar modules feature anti-reflective, hydrophobic glass coatings that limit dust adhesion.
Coastal cities like Walvis Bay experience heavy salt spray. To protect the luminaires, we manufacture our split solar streetlights with die-cast ADC12 aluminum housings treated with electrophoretic powder coating. All assembly fasteners and pole brackets are made of grade 304 or 316 stainless steel to prevent rust and corrosion.
Even under clear skies, dust storms can block sunlight. Wuxi Zeteo's smart MPPT controllers track the solar panel's output at high conversion efficiencies (up to 99%), maximizing energy harvesting even in dusty conditions. The controllers feature programmable dimming profiles (e.g., 100% brightness for the first 4 hours, followed by motion-activated dimming) to conserve battery capacity through periods of low sunlight.
For Namibian municipalities and private developers, meeting regulatory standards is essential for project approvals. All Wuxi Zeteo products are manufactured under strict international certifications, including ISO 9001, ISO 14001, and ISO 45001. Our systems carry CE, TUV, IEC, and CQC marks, making them compatible with the South African National Standards (SABS) and Namibian Standards Institution (NSI) guidelines.
We supply complete testing documentation for every shipment, including IES files for lighting layout design, wind tunnel test certificates up to 160 km/h, and salt spray resistance certifications. This thorough documentation simplifies municipal approval processes, helping engineering contractors move their projects forward smoothly.

Answers to technical questions about off-grid street lighting projects in Southern Africa.
Integrated designs put the battery, solar panel, and LEDs in a single case, which can overheat when exposed to direct Namibian sun. Split configurations allow the battery pack to be placed separately (such as in an insulated ground enclosure), protecting it from high temperatures. This setup also lets you adjust the solar panel angle independently of the light source, optimizing energy capture.
We build our streetlights with high-grade die-cast ADC12 aluminum housings treated with electrophoretic powder coatings. This helps prevent corrosion in coastal air. Additionally, all exposed fasteners and bracket components are made of marine-grade 304 or 316 stainless steel to ensure durability.
We use premium lithium iron phosphate (LiFePO4) cells managed by a custom Battery Management System (BMS). The BMS prevents overcharging, over-discharging, and overheating. If temperatures exceed safe operating limits, the BMS modulates charging rates to protect the battery cells.
Yes, we support EPC contractors and municipal partners with complete technical documentation. We can provide IES files, Dialux lux maps, and certified wind load calculations to ensure compliance with municipal road lighting standards.
We offer 3-year and 5-year warranties depending on the system configuration. During the warranty period, we supply replacement parts directly from our factory, and our engineering team is available to assist with remote troubleshooting and configuration updates.
