The 120W Industrial Dual-Arm Split-Type Solar Streetlight is a high-capacity off-grid lighting system built around a 120W LED luminaire set, a 240Wp TOPCon solar module, a 960Wh LiFePO4 battery, and a 10 m galvanized steel pole. The dual-arm configuration broadens road-width coverage. The split-type architecture separates panel, battery, controller, and lamp heads — improving thermal management, ease of maintenance, and tilt optimization — and delivers 15%–25% better performance than compact integrated designs in many field installations. From a B2B buyer's perspective reviewing industrial-lighting CAPEX and lifecycle cost, this model is positioned for 12-hour nightly operation, 8-day rainy-weather autonomy, and a turnkey EPC scope.
For procurement teams, EPC contractors, and project developers, this product suits roads, factory site perimeters, mining camps, logistics yards, ports, and municipal roads that require 6–14 m pole-class solar streetlighting. The system uses LiFePO4 chemistry rated for 2,000+ deep cycles, an MPPT controller with 98%+ efficiency, and LED chips rated at 170 lm/W or higher — aligning with the market benchmarks for efficient distributed solar and lighting assets cited by NREL, the IEA, and IRENA. Buyers can also review pole heights, battery reserves, and smart-control options under "View all Solar Street Light products" or "Configure the system online".
This 120W dual-arm split-type solar streetlight is engineered for installations where a single luminaire is insufficient at a 10 m mounting height, or where lateral lighting is required across two traffic directions. With system luminous efficacy above 170 lm/W, theoretical initial flux is approximately 20,400 lm (depending on optics and drive-current configuration). In practical road designs, this output serves industrial access roads, parking-lot lanes, and secondary municipal corridors on 50–250-pole projects targeting balanced illuminance, low glare, and reduced trenching cost.
Compared with a typical grid-connected 120W AC LED streetlight, this solar split system can reduce trenching and cabling by 70%–100% depending on site topography, eliminating roughly 4,380 hours per year of utility power consumption at 12 h/day. Assuming a conventional 120W load with about 10% driver loss, annual grid power demand is approximately 578 kWh/year. Annual energy savings per pole are typically meaningful (excluding civil-works avoidance, meter cost, and reduced outage risk) — consistent with the distributed-lighting economics discussed by the IEA and BloombergNEF.
The split architecture places the 240Wp solar panel on a top bracket or arm with an optimized tilt, while the 960Wh LFP battery is installed at the pole base or in a secure battery box — lowering the center of gravity and making maintenance easier. This architecture is preferred for industrial projects above 80W because it supports larger battery banks, provides better thermal dissipation, and simplifies replacement across a 5–10 year service cycle. In temperate climates with sufficient irradiance, the panel-to-battery ratio is sized for 8-day autonomy and stable dusk-to-dawn operation.
The controller uses MPPT tracking with greater than 98% conversion efficiency, improving harvest by roughly 10%–20% over PWM under variable irradiance. Smart dimming can be programmed across 2–5 time segments or paired with PIR occupancy detection, with motion-adaptive control reducing energy use by up to 60% during low-traffic hours. The electrical architecture follows the core principles of IEC 62124 for standalone PV system performance evaluation and the IEC 60598 luminaire safety framework, targeting IP66 for the luminaire and IP67 for the battery and controller compartments (where specified) for dust and water-ingress protection.
The standard configuration uses a 10 m hot-dip galvanized steel pole, selected for an excellent strength-to-cost ratio at current EPC benchmark levels. The dual-arm arrangement improves lateral distribution, illuminating two lane edges or the road plus pedestrian shoulder with better uniformity than a single head. For standard industrial designs, wind-load resistance for a 10 m galvanized structure depends on local geotechnical data, arm length, luminaire surface area, and foundation engineering — but can be specified at approximately 140 km/h.
The 240Wp monocrystalline TOPCon module typically operates in the 19%–23% efficiency range and is designed for a service life of 25 years. TOPCon is increasingly chosen for off-grid streetlights because it improves energy yield in space-constrained installations and can deliver stronger morning/afternoon production than older cell architectures. The 960Wh LiFePO4 battery supports deep cycling, low self-discharge, and typically more than 2,000 cycles of effective life. The integrated BMS includes overcharge, over-discharge, short-circuit, and low-temperature protection. Operating temperature is specified at -20°C to +55°C, suiting temperate and most continental industrial zones.
The LED engine is configured at 120W using industrial-grade chips from Bridgelux, Cree, or Lumileds, with rated life exceeding 50,000 hours. At 12 hours of operation per day, this corresponds to more than 11.4 years before the lumen-maintenance threshold based on nominal LED life — although field replacement intervals may vary with driver and surge events. Typical optics can be selected from Type II, Type III, or Type IV road distributions to match lane width, pole spacing, and mounting setback. Buyers planning 50–500-pole corridor projects should verify illuminance targets, spacing, and uniformity through a photometric simulation before final procurement.
This product category is typically designed against IEC 62124 for standalone PV system evaluation, IEC 60598 for luminaire safety, and IP66/IP67 ingress-protection ratings for outdoor reliability. Solar-module manufacturing is commonly aligned with IEC 61215 and IEC 61730, and the battery system and transport packaging may follow applicable UN and safety requirements depending on shipping mode and destination. B2B projects in Africa, Southeast Asia, the Middle East, and Latin America frequently require these standards on tenders of 20 units or more.
Authoritative industry references support the design logic used here. NREL has repeatedly documented the importance of module orientation, battery capacity sizing, and load control in standalone PV applications. IRENA and the IEA highlight off-grid solar as a cost-effective infrastructure solution in regions with weak grids or expensive electricity. BloombergNEF and Wood Mackenzie track the continuous decline in solar and battery costs that improves project economics in distributed-energy applications. These references are relevant because a streetlight integrates four core subsystems — PV generation, battery storage, power electronics, and an efficient LED load — into a single asset class.
The 10 m, 120W, dual-arm configuration is best suited to industrial roads approximately 8–16 m wide, logistics parks with two-way traffic, municipal collector roads, ports, depots, campuses, and large parking-perimeter zones. In typical layouts, pole spacing can range from 25–35 m depending on setback, beam pattern, target average illuminance, and pavement reflectance. Because the system is off-grid, it is particularly attractive where trenching distance exceeds 30–50 m per pole or where utility connection lead time exceeds 8–16 weeks.
In a real-world case, a solar power-plant operator in a MENA industrial zone required perimeter and internal access-road lighting along approximately 2.4 km. By choosing 100–120W split-type solar streetlights on 10 m poles instead of grid-tied equipment, the operator reduced cable trenching by more than 80% and shortened deployment by about 5 weeks by eliminating mid-distance feeder extension. In that use case, motion-adaptive dimming lowered nightly battery consumption by approximately 35%, helping sustain autonomy through winter weather variability.
For buyers comparing alternatives, split-type designs generally outperform all-in-one systems above the 80–100W class because they require larger battery capacity and adjustable panel tilt. Compared with diesel-generator-based lighting, solar systems can cut fuel-related operating cost by more than 90% and eliminate local combustion emissions at the point of use. Compared with conventional grid streetlights, they avoid monthly billing, reduce outage exposure in weak-grid regions, and simplify expansion by adding poles one at a time without resizing transformers.
Optional smart control integrates 4G or LoRa communications to support remote status monitoring, fault alerts, dimming-schedule updates, and asset mapping for 10–1,000 units. Typical data points include battery voltage, state of charge (SOC), charging current, discharging current, controller temperature, lamp runtime, and alarm logs. For municipal or industrial operators managing multi-site assets, cloud visibility can reduce troubleshooting time by 30%–50% and cut unnecessary site visits.
Example smart-dimming schedules include 100% output for 4 hours, 60% for 5 hours, 40% for 3 hours — or triggering brighter output only when motion is detected. This approach aligns with the practical energy-management principles used in standalone solar lighting and can meaningfully extend autonomy through low-irradiance periods. Buyers interested in control, telemetry, or hybrid features can consult "Learn the topic" and "Request a custom quote" to discuss project-specific communication architecture.
For a 10 m pole, the typical concrete foundation budget sits at standard installation levels, with actual dimensions depending on soil bearing capacity, frost depth, and wind-load conditions. Installation generally includes excavation, anchor-cage placement, concrete curing, pole erection, panel mounting, battery/controller wiring, luminaire aiming, and commissioning checks. On 50–100-pole projects, an experienced crew often installs 6–12 poles per day once foundation preparation is complete — faster than many grid-lighting projects that require trenching, conduit, and utility coordination.
Maintenance is typically limited to 2–4 inspections per year — including panel cleaning, bolt-torque checks, battery-compartment inspection, and controller-log review. Because the battery is not integrated into the luminaire body, replacement and testing are simpler than with compact units, reducing maintenance labor across the asset life. In dusty industrial environments, cleaning panels every 3–6 months can recover measurable yield — even 5%–10% soiling losses can impact winter autonomy if unmanaged. Buyers can also consult "Learn the topic" for maintenance planning and system optimization.

This model sits in a practical upper-mid range with balanced output, autonomy, and serviceability. The 120W LED, 240Wp PV, 960Wh LFP combination provides stronger reserve power and broader coverage than 60–80W compact lighting, while staying below the weight and cost profile of 150–200W heavy-duty systems. The dual-arm format is particularly useful when one pole must serve two directions, and in some layouts can reduce pole count by 10%–20% versus a single-sided arrangement.
Procurement teams seeking standardization benefit from a simpler tender evaluation because the design uses galvanized steel, LFP storage, MPPT control, and IEC-referenced engineering. For developers, the split architecture makes service access and component replacement easier within the framework of a 3-year system warranty and 5-year pole warranty. For municipal and industrial operators, the off-grid design improves outage resilience and enables deployment in remote zones where utility infrastructure may be months or years away.
In summary, the 120W Industrial Dual-Arm Split-Type Solar Streetlight is a technically balanced solution for professional off-grid road lighting. It combines 20,400 lm-class output, 8-day autonomy, a 10 m mounting height, and a 240Wp/960Wh energy package with standards-based engineering and scalable EPC delivery.
