Solar Street Light Project Quotation Architecture & Cost Modeling
A rigorous engineering breakdown of Bill of Materials (BOM), structural dynamics, electrochemical storage, and life-cycle capital allocations for international public works.
Bill of Quantities (BOQ) Anatomy
An institutional-grade project quotation from our Gaoyou manufacturing complex separates baseline hardware from project-specific compliance requirements. Bids encompass raw steel weight, zinc coating volume, monocrystalline cell grading, and lithium battery cell chemistry.
- Certified Q235B / Q355B base structural analysis
- Tier-1 A-grade TOPCon/Monocrystalline cell costing
- LiFePO4 cell cycle longevity audits (≥4,000 cycles)
Photometric & Sizing Optimization
Quotation variance frequently results from incorrect optical and autonomy dimensioning. We leverage DIALux simulations to balance peak lumen output against battery depth of discharge (DoD), preventing premature systemic failure while slashing unnecessary balance-of-system capital.
- EN 13201 Class M1 to M5 compliance profiles
- NASA/PVGIS solar insolation data matching
- 3 to 5 continuous rainy day autonomy sizing
LCOE & CAPEX vs. OPEX Analysis
Eliminating underground electrical trenching, high-voltage copper cabling, substations, and recurring utility tariff billing yields a CAPEX amortization period of 2.2 to 3.8 years. The resulting Levelized Cost of Light (LCOL) demonstrates significant savings over grid-tied luminaires.
- Zero linear cable trenching & transformer outlay
- Immunity to grid-level rolling blackouts
- Reduced civil excavation and asphalt repaving
Engineering Quotation Directive for EPC Contractors
When submitting international tenders, generic quotations lacking precise steel wall thickness tolerances (±0.2mm), hot-dip galvanizing bath certification (ASTM A123/EN ISO 1461), and battery thermal throttling points risk immediate disqualification. Xintong factory provides auditable technical compliance documents, comprehensive calculation sheets, and mill test certificates (MTC) alongside commercial pricing.

Frequently Asked Questions: Factory Quotations & Engineering Specs
Detailed technical answers for EPC tendering teams, procurement directors, and municipal consulting engineers.
Are you a manufacturing factory or a trading company?
Xintong is an original equipment manufacturer (OEM/ODM). Founded in 1999, we operate an expansive 100,000 m² production complex in Gaoyou, Jiangsu Province, China. Our facilities feature 7 full-stack production lines encompassing steel sheet leveling, CNC shearing, single-pass tandem press brake bending, longitudinal submerged-arc welding, automated hot-dip galvanizing, electrostatic powder finishing, and cleanroom SMT luminaire assembly. International clients are welcome to perform on-site factory audits or schedule third-party inspections (e.g., SGS, TÜV, Bureau Veritas).
What specific engineering parameters are required to receive an accurate project quotation?
To deliver an auditable BOQ quotation, our engineering team requires: (1) Target road classification or required lux/foot-candle levels; (2) Road cross-section geometry, including lane counts, median widths, and setback distances; (3) Project site coordinates or historical solar insolation levels (kWh/m²/day); (4) Maximum localized design wind velocity (m/s or km/h); (5) Required continuous autonomy days (typically 3 to 5 rainy/overcast days); and (6) Pole structure preferences (conical, octagonal, or cylindrical with single or double arm configurations).
Which international quality standards and testing certifications govern your production?
Our street lighting poles and systems conform to European (EN 40-2, EN 40-3, EN 40-5), American (AASHTO LTS, ASTM A123, ASTM A572), and international ISO 9001:2015, ISO 14001:2015, and ISO 45001 safety frameworks. Optical luminaires and solar electronics comply with CE-LVD, CE-EMC, RoHS, CB, IEC 60598, IEC 61215, IEC 61730, and IP66/IK10 ingress/impact testing standards. We provide certified Mill Test Certificates (MTC) and zinc bath immersion records with every export container.
How does Xintong guarantee structural corrosion resistance over 25+ years?
We utilize high-yield structural steel (Q235B and Q355B). After forming and robotic welding, every shaft undergoes chemical pickling to remove surface scale before complete immersion in a molten zinc kettle maintained at 450°C. This creates metallurgical zinc-iron alloy layers on both interior and exterior surfaces with a minimum average thickness of 86μm. For coastal deployments, an additional electrostatic thermoset TGIC polyester powder coat (80–120μm) is baked on, providing robust protection in C5-I and C5-M high-salinity marine environments.
Do you provide complete engineering submittal dossiers for international tenders?
Yes. We regularly support EPC contractors bidding on World Bank, Asian Development Bank, and national municipal tenders. We provide full submittal packages including photometric DIALux files, 3D luminaire models, CAD foundation and anchor-bolt layout schematics, structural finite-element wind deflection calculations, battery discharge curves, and warranty documentation up to 10 years depending on selected component tiers.
