| Product Safety Compliance | Electrical, mechanical, photobiological, and luminaire safety controls. | Applicable test reports or certificates based on IEC 60598-1 and the relevant parts of the IEC 60598 series. | Complete laboratory reports showing the exact model number, test standard, test date, and issuing laboratory. | 15% |
| Ingress Protection | Protection against dust and water for the luminaire, battery enclosure, controller, and cable connections. | IP65 is a practical minimum for outdoor flood-light housings; IP66 may be preferred for harsher exposure. The rating should cover the complete assembled product. | IP test report identifying the tested enclosure and configuration. Do not rely only on an unverified “waterproof” claim. | 10% |
| Impact Resistance | Resistance of the housing, lens, and solar-panel assembly to accidental impacts. | A documented IK rating, such as IK08 or higher, when the installation environment requires impact protection. | Test report referencing IEC 62262 or an equivalent recognized method, with the tested product clearly identified. | 5% |
| LED Performance | Light output, efficacy, color consistency, useful lifetime, and thermal management. | Compare delivered lumens and system efficacy rather than LED chip wattage alone. Require LM-80/TM-21 evidence where lifetime claims are material to the project. | Photometric report, IES/LDT file, lumen-maintenance data, LED-bin information, and thermal design details. | 12% |
| Solar Panel Quality | Panel technology, rated power, conversion efficiency, mounting strength, and performance under actual sunlight conditions. | The panel rating must be sufficient to recharge the battery for the specified operating schedule and local solar conditions; monocrystalline panels are commonly used for compact outdoor systems. | Panel datasheet, power-tolerance information, certification records, dimensions, and a clearly defined charging calculation. | 10% |
| Battery and Energy Storage | Battery chemistry, usable capacity, cycle life, low-temperature behavior, and replacement design. | LiFePO4 is generally preferred for outdoor solar lighting because of its thermal stability and cycle-life characteristics. Capacity should be stated in watt-hours, not only ampere-hours. | Battery datasheet, protection-circuit details, cycle-life test conditions, temperature limits, and replacement instructions. | 15% |
| Runtime and Autonomy | Nightly operating duration, dimming schedule, reserve capacity, and performance during consecutive cloudy days. | The supplier should provide a location-based design calculation covering peak-load operation, daily solar availability, battery reserve, and the requested autonomy period. | Energy-balance calculation using panel wattage, battery watt-hours, LED load, controller efficiency, local solar data, and lighting profile. | 12% |
| Lighting Control | Photocell operation, motion sensing, dimming, timer settings, remote control, and protection against unstable switching. | Controls should support the project’s operating profile and retain settings after power interruption. Motion-sensor specifications should include detection range and mounting conditions. | Controller datasheet, wiring diagram, control demonstration, configuration guide, and sample operating schedule. | 6% |
| Mechanical Design | Housing material, corrosion resistance, fasteners, adjustable brackets, cable routing, and service access. | Powder-coated aluminum or equivalent corrosion-resistant construction is generally suitable for outdoor use when the coating and hardware are properly specified. | Material declarations, coating specification, salt-spray or corrosion-test results where relevant, dimensional drawings, and installation instructions. | 6% |
| Quality Management | Production consistency, incoming inspection, process control, traceability, and final inspection. | A documented quality-management system, such as ISO 9001 certification, is useful but should be verified and supplemented with product-specific inspection records. | Current certificate scope, factory audit results, quality-control plan, sampling standard, and recent pre-shipment inspection report. | 5% |
| Testing and Reliability | Environmental, thermal, charging, vibration, water-ingress, and repeated on/off testing. | Testing should reproduce the intended installation conditions and include the complete system rather than isolated components only. | Test plans and results for temperature cycling, charging and discharging, vibration, waterproofing, and continuous operation. | 4% |
| Customization Capability | Optical distribution, color temperature, mounting arrangement, battery capacity, panel size, control logic, and branding-free project documentation. | Changes should be supported by revised drawings, a new bill of materials, sample approval, and confirmation that compliance remains valid for the modified model. | Engineering drawings, prototype records, sample-testing results, change-control documents, and approved production samples. | 3% |
| Warranty and After-Sales Support | Warranty scope, exclusions, replacement parts, technical response, and handling of battery degradation. | The warranty should define coverage by component, claim evidence, response time, spare-parts availability, and the treatment of consumable or aging components. | Signed warranty terms, service-level commitments, spare-parts list, troubleshooting guide, and escalation contacts. | 5% |
| Supply and Export Capability | Production capacity, lead time, packaging, export documentation, and shipment consistency. | The supplier should provide a realistic production schedule, packaging specification, inspection milestones, and documentation appropriate to the destination market. | Production plan, packaging test results, sample commercial documents, references for comparable projects, and shipment records with sensitive information removed. | 2% |
