About the Team

Photoelectric Conversion Efficiency:
Measured via professional equipment under standard lighting (AM1.5 spectrum, 1000W/㎡), high-efficiency solar panels typically show 18-22% efficiency, varying by product design.
Electrical Parameters:
Open-circuit voltage and short-circuit current are key to evaluate panel performance, ensuring they meet specification ranges for charging control.
Visual Inspection:
Check for surface defects (scratches, cracks, bubbles) and frame damage to guarantee intact appearance and service life.

Standards Compliance for Solar Street Lights:
Production and testing must adhere to national standards like GB/T 36276-2018, specifying terms, classification, technical requirements, and test methods for solar panels, batteries, and lamps to ensure unified quality.
Road Lighting Standards:
Standards such as GB 5768.2-2009 and CJJ 45-2015 regulate brightness, illumination, and uniformity for different road types. Compliance ensures traffic safety and lighting efficiency.

Test Report Essentials:
Include product basics (model, batch, date). Record test results (data, compliance), e.g., solar panel efficiency vs. standards.
Issue Analysis & Conclusions:
Detail defects (e.g., uneven lighting), root causes (design/assembly), and solutions. State pass/fail with reference standards.
Format & Archiving:
Standardized format (cover, contents, appendix). Archived by the tester for ≥ warranty period, provided to manufacturers for quality improvement and traceability.
