I. Complete Procurement Process for Solar Street Lights in 2026

A standardized procurement process is the foundation for controlling project quality and costs. The following seven stages are interconnected, and procurement teams should proceed step by step to avoid risks from skipping stages.

1.1 Needs Confirmation

Before initiating procurement, the following core information must be clarified:

Project basics: Installation location (province/city/district), road name and grade, road length and width, pole spacing and quantity. This data directly determines luminaire power, pole height, and system configuration.

Usage scenario: Rural roads, municipal roads, residential communities, industrial parks, tourist attractions—each scenario has different requirements for illuminance, design, and smart features. Rural roads prioritize functional lighting with focus on cost-effectiveness and reliability; municipal roads must meet CJJ 45 standards with higher requirements for efficacy, uniformity, and smart functions; scenic areas and commercial streets emphasize coordination between luminaire design and surroundings.

Lighting mode: Nightly operating hours (commonly 8–12 hours), whether multi-period dimming is needed (e.g., full power for first 4 hours, half power for next 6 hours), and consecutive rainy day backup requirement (typically 3–5 days).

Special requirements: Whether smart control functions are needed, specific brand or certification requirements, whether installation services are required from the manufacturer, and project timeline constraints.

It is recommended to involve technical personnel or experienced manufacturers during the needs confirmation stage to avoid repeated solution revisions caused by unclear requirements.

1.2 Solution Design

Once requirements are defined, the solution design phase begins. Professional manufacturers should provide:

• Lighting design report: Road surface illuminance simulation using professional software such as DIALux, outputting iso-illuminance diagrams and data tables to ensure compliance with CJJ 45 or project-agreed illuminance standards;

• System configuration list: Detailed specifications of solar panel wattage and brand, battery type and capacity, controller model and parameters, LED luminaire power and efficacy, pole height and material wall thickness;

• Layout and foundation drawings: Pole layout plan, pole foundation construction drawing (including anchor bolts and concrete grade), and electrical wiring diagram;

• Investment estimate: Itemized cost summary including product costs, transportation, installation (if applicable), and taxes.

Upon receiving the proposal, procurement teams should重点 verify whether solar panel wattage matches LED power, whether battery capacity meets cloudy day backup needs, whether luminaire efficacy meets standards, and whether pole wall thickness is reasonable. It is advisable to request proposals from 2–3 manufacturers for comparison.

1.3 Manufacturer Screening

Manufacturer screening is the most critical stage in the procurement process. Evaluation should cover the following dimensions:

Production capability: Factory area, production line count, monthly capacity, and key production equipment. Nandesolar's 58,000 m² factory and full industry chain self-production provide significant advantages in delivery assurance and quality control.

Qualifications and certifications: Business license, urban and road lighting qualifications, ISO system certifications, product test reports, and certification certificates (CE, RoHS, CQC, etc.). Request original scanned copies for verification.

Project experience: Track record of similar projects in the past 3 years, with emphasis on cases similar to the current project scenario. Request key contract pages and acceptance reports.

Technical capability: Number of patents, R&D team size, and whether independent design capability exists. Nandesolar holds 12 international patents and 60 national patents, demonstrating deep technical expertise.

After-sales service: Warranty duration, service response time, and whether service points or partners exist at the project location.

On-site inspection: When conditions permit, visiting the manufacturer's factory to inspect production lines, testing equipment, warehouse materials, and finished product quality is the most direct way to assess true capabilities.

1.4 Sample Testing

After shortlisting candidate manufacturers, sample testing is recommended. Key inspection areas:

• Appearance and workmanship: Pole welds should be smooth, galvanizing and powder coating should be uniform, luminaire housing should be smooth without burrs, and wiring should be neat;

• Waterproof test: Spray or submerge luminaires and battery enclosures according to stated IP rating to check for water ingress;

• Dimension verification: Measure pole height, wall thickness, flange dimensions, and solar panel size against the proposed specifications.

Sample testing costs are typically borne by the procurement party or negotiated between both parties. Sample costs may be refunded or deducted from the bulk order upon successful delivery. Approved samples should be sealed as reference standards for bulk order acceptance.

1.5 Contract Signing

The contract is a legal document protecting both parties' interests and should include the following key clauses:

• Product details and technical specifications: Itemize brand, model, specification, quantity, and unit price for each component. Avoid vague terms like "equivalent quality" or "national standard";

• Quality standards: Specify applicable national and industry standards (CJJ 45, GB 7000, GB/T 24827, etc.) and designate which institution's test reports govern product inspection;

• Delivery time and location: Specify production cycle, delivery date, delivery location, and shipping method;

• Payment terms: Common payment schedule: 30% advance payment, 60%–80% before shipment, 95% upon acceptance, 5% retention released after 1 year. Specific ratios to be negotiated;

• Acceptance criteria and methods: Define inspection items, methods, and standards; designate third-party testing institutions if required;

• Warranty and after-sales: Warranty duration, coverage, response time, and responsibility division for repairs and replacements;

• Breach of contract liability: Penalties and compensation for late delivery, quality failures, and inadequate after-sales service;

• Intellectual property and confidentiality: Projects involving custom designs or smart systems should specify IP ownership.

Contract appendices should include technical specifications, drawings, and photos of approved samples, carrying equal legal weight as the main contract.

1.6 Production and Delivery

After contract signing, the production phase begins. Procurement teams should track progress:

• Production progress confirmation: Request progress photos or videos at mid-stage and late-stage. For key milestones (raw material arrival, pole welding completion, galvanizing completion, luminaire assembly), arrange on-site visits;

• Factory inspection: Request pre-shipment inspection reports. Procurement teams may commission third-party inspection agencies for pre-shipment inspection (PSI), covering packaging, quantity, appearance, and key performance spot checks;

• Logistics arrangement: Specify shipping method (full truckload / LTL), freight responsibility, and insurance coverage. Solar panels are fragile and require wooden frame packaging with cargo insurance; long poles need appropriate vehicle arrangements;

• Arrival inspection: Upon delivery, immediately check packaging integrity, quantity against packing lists, and transport damage. Photograph any damage or missing items on-site and contact the manufacturer and logistics company.

1.7 Installation, Commissioning, and Acceptance

Installation directly affects the performance and lifespan of solar street lights and must strictly follow specifications:

• Foundation construction: Excavate foundation pits per manufacturer drawings, tie rebars, embed anchor bolts and conduit pipes, and pour concrete. Foundation dimensions and concrete grade must meet drawing requirements—generally, 6m poles require foundations no smaller than 500mm × 500mm × 800mm, 12m poles no smaller than 1000mm × 1000mm × 1500mm. Concrete grade no lower than C25 with minimum 7-day curing;

• Pole erection: After foundation concrete reaches design strength, erect poles using cranes with manual assistance, ensuring pole verticality deviation does not exceed 0.5% of pole height;

• Solar panel installation: Face due south (in Northern Hemisphere), set tilt angle based on project latitude (generally latitude + 5°–10°), avoiding building and tree shading;

• Luminaire installation: Adjust luminaire tilt to design angle (generally not exceeding 15°), tighten mounting bolts, and waterproof connectors;

• Wiring: Connect solar panel, battery, controller, and luminaire per wiring diagram, observing polarity, and waterproofing/insulating terminals;

• System commissioning: After power-on, verify proper lighting, controller parameters, and smart control network connectivity;

• Completion acceptance:逐项 inspect per contract acceptance criteria, measure road surface illuminance, check appearance and installation quality, and compile completion documentation (as-built drawings, test reports, certificates, manuals, etc.).

Nandesolar can assist clients in preparing product documentation for subsidy applications.

13. What items should be tested during sample evaluation?

Recommended tests include: appearance and workmanship inspection, actual power and illuminance measurement, color temperature verification, continuous charge/discharge testing (minimum 3 days), waterproof testing, pole wall thickness measurement, and solar panel wattage verification. Compare results against manufacturer specifications and contract technical requirements.

14. Can smart functions be added to solar street lights later?

Some products support this. If communication interfaces and mounting positions were reserved during initial procurement, individual controllers, sensors, and other modules can be added later. It is recommended to consider future expansion needs at first procurement, choosing controllers and pole designs that support smart upgrades to avoid difficult retrofits.

15. How to ensure quality consistency in large-volume procurement?

First, select manufacturers with scaled production capability and quality management systems; second, specify detailed technical and acceptance standards in contracts; third, arrange mid-production and pre-shipment inspections; fourth, conduct proportional sampling upon arrival with 100% verification of key parameters; fifth, retain sealed reference samples for comparison. Nandesolar is ISO 9001 certified, and its full industry chain production model facilitates quality consistency control.

16. How are after-sales repair costs calculated?

During the warranty period, product quality defects are repaired or replaced free of charge by the manufacturer; labor and travel costs are borne per contract terms. Post-warranty or human-damage repairs incur component cost fees and reasonable labor charges. It is recommended to specify post-warranty spare part pricing and service fee standards in contracts.

17. What should be noted for export procurement?

Export procurement requires attention to target market certification requirements (EU CE, RoHS; Africa SONCAP; Middle East SASO, etc.), voltage and plug standards, and packaging and labeling requirements. Nandesolar's products are certified to 30+ international standards and exported to 30+ countries, with extensive export experience providing customs declaration, freight forwarding, and other export support services.

18. How long after procurement will goods be received?

Depending on product type, quantity, and shipping distance, standard products generally ship within 7–15 days after payment, with logistics taking 3–10 days; custom products require 15–30 days production. Specify delivery dates and late delivery penalties in contracts for progress tracking.

X. Procurement Recommendations Summary

The solar street light market continues to develop in 2026 with increasingly mature technology, but industry concentration remains low with significant quality variation. Procurement teams are advised to follow these principles when selecting manufacturers:

First, prioritize full industry chain manufacturers. Enterprises that self-produce core components have clear advantages in quality control, cost optimization, and after-sales service. Nandesolar's 25 years of full industry chain expertise, 58,000 m² factory, and 1 million sets annual delivery capacity exemplify this category.

Second, value qualifications and track record. Municipal projects must select manufacturers with appropriate qualifications. Rural and park projects should also verify similar project experience. Qualifications and project history objectively reflect a manufacturer's comprehensive capabilities.

Third, don't focus solely on price. Solar street lights are long-term outdoor installations. Initial procurement costs represent only a portion of lifecycle costs. Maintenance, replacement, and energy losses from poor quality may far exceed any procurement savings.

Fourth, visit factories in person. When possible, visit the manufacturer's facility. Production line scale, testing equipment configuration, warehouse material management, and employee professionalism all reflect the manufacturer's true capabilities.

Fifth, ensure detailed contract terms. Technical specifications, acceptance criteria, payment schedules, warranty commitments, and breach liabilities must all be documented. Verbal promises should be avoided. The more detailed the contract, the fewer disputes downstream.
