Product Introduction
◎Advantages of monocrystalline silicon cells: The 200W solar street light adopts monocrystalline silicon cells, whose conversion efficiency of 22%-24%, excellent low-light performance and low attenuation rate (0.5%/year) significantly increase power generation. Compared with polycrystalline silicon of the same power, the annual power generation is 15%-20% higher, and the cost per kilowatt-hour is reduced by 27%.
◎Intelligent monitoring function: Integrating a 4K camera, PIR sensor and edge computing chip, it realizes face/license plate recognition, abnormal behavior analysis and real-time transmission, improving the efficiency of traffic management. Moreover, solar power supply ensures lifetime in cloudy and rainy days.
◎Scenario-based solutions: Covering urban transportation hubs (integrated with traffic flow statistics and charging interfaces), rural revitalization (one-key alarm and emergency broadcasting) and extreme environments (IP65 protection and graphene heat dissipation). Compared with traditional solutions, the cost is reduced by 40%-65%, and the failure rate is lower than 0.3%.
Monocrystalline Silicon Cells
1.Photoelectric Conversion Efficiency
Monocrystalline silicon solar cells feature a continuous lattice structure and high-purity materials (purity >99.999%) as their core advantages. The maximum laboratory conversion efficiency reaches 25.7%, and the efficiency of mass-produced modules is generally stable at 22%-24%, which is 20%-30% higher than that of mainstream polycrystalline silicon (18%-21%). Taking a 200W street light as an example:
Comparison of daily power generation (taking North China, China as an example):
◎Monocrystalline silicon module: 5.8kWh/day (peak sunshine 6 hours × 200W × 0.98 system efficiency)
◎Polycrystalline silicon module: 4.7kWh/day (15% efficiency attenuation under the same conditions)
2.Power Generation Stability in Low-Light Environments
The dark blue anti-reflective coating and low-light response technology of monocrystalline silicon cells enable them to maintain efficient power generation in rainy days or early morning/evening:
Low-light performance test (light intensity 200W/m²):
◎Monocrystalline silicon module output power: 120W (conversion efficiency 24%)
◎Polycrystalline silicon module output power: 85W (conversion efficiency 17%)
