All-In-One Vs Split Type Solar Street Lights: Which Is Better?
All-in-One vs Split Type Solar Street Lights: Which is Better?
When selecting solar street lighting for your project, one of the most critical decisions you'll face is choosing between All-in-One (Integrated) and Split Type systems. At ZENOME, we manufacture both configurations, and we believe the "best" choice depends entirely on your specific application requirements. This guide provides an objective technical comparison to help you make an informed decision.
Understanding the Fundamentals
All-in-One (Integrated) Solar Street Lights
In an All-in-One design, the solar panel, lithium battery, LED module, MPPT controller, and smart sensors are integrated into a single compact housing that mounts directly onto the pole arm. There are no external cables, no separate panel brackets, and no underground wiring.
ZENOME's All-in-One Series Features:
Plug-and-Play Installation: Pre-configured at factory, ready for immediate deployment
LiFePO₄ Battery Technology: 2,000–3,000 cycles, 6–10 year lifespan, operating range -20°C to +60°C
MPPT Intelligent Controller: Up to 98% charging efficiency vs. 70–80% with conventional PWM controllers
High-Efficacy LEDs: 160–200 lm/W output (3030/5050 SMD LEDs)
Smart Sensors: Microwave radar motion detection (5–12m range) with auto-dimming
IP65+ Weatherproofing: Dust-tight, water-jet resistant aluminum housing
Split Type Solar Street Lights
In a Split Type system, the solar panel is mounted separately-typically on top of the pole or an adjacent structure-while the battery is housed in a ground-level enclosure or pole-mounted box. This separation allows for larger solar panel surface areas and independent component optimization.
ZENOME's Split Type Series Features:
Modular Architecture: Independent sizing of panel, battery, and LED components
Adjustable Panel Orientation: 360° horizontal adjustability with variable tilt angles (30°–45°) for maximum solar yield
High-Capacity Battery Options: 100–200Ah configurations for 5–7 days autonomy
High-Power LED Engines: Up to 200W+ output for wide roads and highways
Ground-Level Battery Access: Easier maintenance and thermal management
Enhanced Surge Protection: Critical for coastal areas and long corridors
Head-to-Head Technical Comparison
| Feature | All-in-One | Split Type |
|---|---|---|
| Installation Time | 15–30 minutes per unit | 30–60 minutes per unit |
| Installation Complexity | Minimal-no wiring, no trenching | Moderate-cabling between components |
| Power Range | 30W – 120W LED output | 100W – 300W+ LED output |
| Solar Panel Size | Limited by housing (max ~1.2㎡) | Flexible (1.5–3㎡+ possible) |
| Battery Capacity | 20–100Ah (2–3 days autonomy) | 100–200Ah (5–7 days autonomy) |
| Panel Adjustability | Fixed angle (optimized for equator–45° latitude) | 360° rotation + variable tilt |
| Best Latitude Range | Equator to ~45° (high solar irradiance) | All latitudes, especially >45° |
| Maintenance Access | Unit replacement or modular internal service | Component-level replacement |
| Theft/Vandalism Risk | Low (integrated, elevated) | Moderate (battery box requires security) |
| Wind Resistance | Excellent (low-profile, IK10 rated) | Superior (panel mounted at pole top) |
| Thermal Management | Integrated heat dissipation design | Superior (components separated) |
| Smart City Ready | Basic IoT (remote monitoring optional) | Full IoT integration (LoRa/NB-IoT) |
| Initial Cost | Lower | Higher |
| 5-Year TCO | Competitive for small-medium projects | Lower for large-scale deployments |

When to Choose All-in-One
Ideal Applications:
Municipal streets and residential roads
Parks, pathways, and recreational areas
Parking lots and commercial complexes
Rural lanes and feeder roads
Temporary lighting (construction sites, events)
Projects requiring rapid deployment
Key Advantages:
1. Installation Efficiency All-in-One systems eliminate underground cabling and complex wiring. A single technician can install a unit in 15–30 minutes using standard tools-reducing labor costs by 60–70% compared to Split Type systems.
2. Aesthetic Integration The sleek, compact design blends seamlessly into urban and suburban environments. No visible cables or bulky external components-ideal for locations where visual appeal matters.
3. Cost-Effectiveness Lower initial hardware costs combined with minimal installation expenses make All-in-One the economical choice for small-to-medium scale projects. Total project cost savings of 30–50% are typical.
4. Security Integrated components at elevation significantly reduce theft risk. No exposed copper wiring or accessible battery boxes to target.
5. Portability Easy to relocate if lighting needs change-perfect for temporary installations or phased project rollouts.
When to Choose Split Type
Ideal Applications:
Primary highways and expressways
Wide arterial roads (12m+ width)
High-latitude regions (>45°N or S)
Areas with frequent overcast weather requiring 5+ days autonomy
Industrial zones and large-scale commercial yards
Smart city infrastructure requiring advanced IoT integration
Key Advantages:
1. Superior Energy Generation Independent solar panels can be oversized and precisely oriented to capture 20–30% more solar energy than fixed All-in-One panels. Critical for high-latitude locations or areas with suboptimal sun exposure.
2. Extended Autonomy Larger battery capacities (up to 200Ah) support 5–7 consecutive cloudy days without recharge-essential for monsoon regions or critical infrastructure where lighting cannot fail.
3. High Lumen Output No space constraints on LED engines means Split Type systems can deliver 8,000–20,000+ lumens for wide highway lanes and high-mast installations.
4. Enhanced Durability Separate component mounting reduces thermal stress. Batteries and electronics operate cooler when not enclosed with solar panels, extending lifespan by 30–50% in hot climates.
5. Maintenance Accessibility Ground-level battery boxes allow faster, safer servicing without cherry pickers or traffic disruption-reducing long-term maintenance costs for municipal fleets.
6. Future-Proof Scalability Modular design supports easy upgrades to smart city platforms, including adaptive lighting policies and central management systems.
ZENOME's Engineering Recommendations
For Most Projects (80% of Applications)
Choose All-in-One. For regions between 45°N and 45°S latitude-including most of Asia, Africa, the Middle East, South America, and southern Europe-All-in-One systems provide sufficient performance with significantly lower total project costs.
For Demanding Applications
Choose Split Type when:
Pole height exceeds 8–9 meters
Road width exceeds 12 meters
Project location is above 45° latitude
Required autonomy exceeds 3 days
LED output requirement exceeds 120W equivalent
Smart city integration is planned
24/7 highway reliability is mandatory
Quality Assurance: The ZENOME Standard
Regardless of configuration, all ZENOME solar street lights feature:
