View Product SeriesThe Global Transition to Industrial-Grade Turnkey Solar Lighting EPC
In modern infrastructure procurement, international EPC (Engineering, Procurement, and Construction) contractors, state transport ministries, and multilateral financing bodies (World Bank, ADB, AfDB) have permanently shifted away from transactional component trading. Utility street lighting demands lifecycle risk engineering, structural certitude, and documented bankability.
Levelized Cost of Light (LCoL)
Traditional municipal models solely evaluated upfront CapEx, resulting in massive field failures due to low-grade ternary batteries, unverified solar yield, and non-galvanized sub-gauge steel. Modern EPC calculations evaluate Total Cost of Ownership (TCO) across a 25-year operational lifecycle, prioritizing high luminous efficacy (>210 lm/W) and maintenance-free LiFePO4 cells.
Structural Wind Engineering
Solar lighting columns carry massive effective projected areas (EPA) due to tilted photovoltaic panels and battery enclosures. Substandard poles collapse under dynamic wind buffeting. Xintong provides Finite Element Analysis (FEA) compliant with AASHTO LTS-6 and EN 40-3-1, verifying resistance against ultimate gust speeds exceeding 160–220 km/h in coastal typhoon paths.
Sovereign Compliance & Tender Rigor
Large-scale tenders require non-negotiable compliance documentation: mill test certificates under EN 10204 3.1, hot-dip galvanizing validation per ISO 1461 / ASTM A123, photometric IES files, DIALux simulation reports, and battery safety certifications (UN38.3, IEC 62133, IEC 62619). We equip EPC partners with bid-winning documentation from day one.
EPC Engineering Note: Single-Source Accountability
Procuring poles from fabricators, solar panels from distributors, and LED luminaires from third parties inevitably introduces system impedance mismatches, warranty finger-pointing, and installation delays. Yangzhou Xintong Traffic Equipment Group controls the complete vertical value chain within our 100,000 m² Gaoyou industrial complex—from raw Q235B/Q355B coil uncoiling to robotic SMT electronics assembly.

Batwing Precision Optics
Our luminaire modules feature multi-cavity optical-grade PMMA lenses with specialized batwing light distribution curves (Type II-M, Type III-M). This eliminates the inefficient "hotspot" directly beneath the pole, maintaining high overall road uniformity (U0 > 0.40, UI > 0.70) while stretching pole-to-pole spacing up to 35–45 meters, slashing project pole count by 20%.
Adaptive Dimming AI Profiling
Embedded microcontrollers automatically compute real-time battery State of Charge (SoC), historical sunlight irradiance patterns, and local traffic density. System output shifts seamlessly between constant illumination, progressive post-midnight dimming (e.g., 100% to 50% to 30%), and microwave motion trigger response to preserve autonomy indefinitely.
Cloud-Based Smart City CMS
Integrated smart city poles interface directly with municipal operations centers via open RESTful APIs and standard MQTT protocols. Municipal engineers monitor voltage, operating temperature, current draw, and lumen degradation in real time, executing automated fault isolation and dramatically reducing maintenance patrol overhead.

Technical, contractual, and operational answers addressing the questions international procurement directors and highway consulting engineers ask during tender preparation.
Q1: How does Xintong calculate column wall thickness and anchor bolt sizing for hurricane-prone regions?
We utilize 3D Finite Element Analysis (FEA) compliant with AASHTO LTS-6 and EN 40 standards. Calculations factor in local 3-second gust velocities, pole height, bracket outreach, luminaire weight, and the effective projected area (EPA) of the solar panel. We optimize the tapered polygonal cross-section, base flange plate thickness, and anchor bolt embedment depth using high-tensile Grade 8.8 bolts.
Q2: What battery chemistry does Xintong employ to prevent thermal runaway in desert climates exceeding 50°C?
We exclusively use Grade-A Lithium Iron Phosphate (LiFePO4) or high-temperature Sodium-ion chemistries. Unlike conventional NMC or recycled lithium cells, our LiFePO4 cells feature an olivine crystalline structure that remains thermally stable up to 270°C without risk of combustion. Our smart BMS provides multi-stage thermal monitoring, automatic current derating, and cell balancing.
Q3: Can Xintong provide complete DIALux lighting simulations for tender submissions?
Yes. Our senior photometric engineers deliver comprehensive DIALux evo simulations that meet your exact road profile, median width, mounting height, and target lighting class (e.g., M1–M5, C0–C5 per EN 13201). Reports provide average road luminance (Lav), overall uniformity (U0), longitudinal uniformity (Ul), and threshold increment (TI) glare values ready for client presentation.
Q4: How does hot-dip galvanizing prevent internal rust, and what is its certified service life?
Our poles are immersed in a 450°C molten zinc bath after all cutting, bending, and welding operations are complete. This coats both the exterior and interior surfaces with a protective zinc-iron alloy layer (>86–100 μm per ASTM A123 / ISO 1461). This provides over 25–30 years of maintenance-free cathodic protection in typical C3/C4 environments.
Q5: What are the operational differences between All-In-One and Split-Type systems in high-latitude projects?
All-in-One systems integrate the solar panel, luminaire, and battery into a single sleek casing—ideal for urban boulevards and high-irradiance zones. Split-type configurations, however, allow the solar panel to tilt independently to maximize energy harvest at high latitudes, while providing space for larger battery banks to support 5–7 days of rainy or snowy autonomy.
Q6: How are container shipments packaged to eliminate transit damage to painted surfaces?
All galvanized and powder-coated columns are wrapped in protective bubble wrap and thick geotextile felt blankets, with critical friction points reinforced by multi-layer corrugated padding. Nested poles are separated by heavy non-abrasive spacers, and the entire load is secured with high-tensile polyester strapping to ensure damage-free ocean transit.
Q7: What IoT communication protocols are supported for smart city integration?
Our intelligent controllers support cellular Cat-M1, NB-IoT, LoRaWAN, and Zigbee mesh protocols. Luminaires connect directly to our cloud-native Central Management System (CMS) or your municipal SCADA platform via open JSON/RESTful APIs, giving operators individual luminaire control, automated fault logging, and energy monitoring.
Q8: What warranty coverage and lifecycle support does Xintong provide on international EPC contracts?
We offer comprehensive tiered warranties of 5, 8, or 10 years backed by contractual spare-parts reserves and direct engineering support. Should any field failure occur within the warranty period, root-cause analysis is conducted immediately and replacement components are dispatched under priority logistics to protect your installation timeline.
