Product Description

IP67 Auto-cleaning Smart Solar Municipal Road Lights

The lighting application part is exactly the same as that of a regular integrated solar street light. A dedicated sliding track for the cleaning module is added on the aluminum profile, ensuring the photovoltaic panel remains free from dust and debris.

🔧 Self-Cleaning Module: It slides on a dedicated track designed on the main profile. Brushes under this module clean the PV panel automatically. This system is convenient for installation, disassembly, and maintenance.

Production & Quality

Frequently Asked Questions

Q1: How does the self-cleaning system work?

The system features an independent cleaning module with built-in brushes that slide along a dedicated track on the solar panel, removing dust and debris automatically at preset intervals (typically morning and evening).

Q2: What is the benefit of the LoRaWAN control system?

LoRaWAN allows for long-range wireless communication with street light nodes, enabling remote monitoring of power, voltage, and temperature, as well as customized dimming schedules from a central server.

Q3: How long can the light operate during rainy or cloudy days?

Thanks to the high-capacity LiFePO4 battery and MPPT controller, the system provides 3-5 days of backup power ensuring continuous lighting even without direct sunlight.

Q4: What is the lifespan of the components?

The monocrystalline solar panels have a lifespan of up to 25 years, while the high-quality LiFePO4 batteries are designed for over 5000 cycles, lasting up to 10 years.

Q5: Is the light fixture durable enough for industrial environments?

Yes, the body is made of high-end aluminum alloy with anodizing treatment and features an IP66/IP67 rating, making it resistant to corrosion and strong environmental interference.

Q6: Can I remotely adjust the brightness of the lights?

Absolutely. The integrated smart controller supports 0-10V and PWM dimming, allowing users to adjust brightness levels based on time or motion sensor triggers via the management platform.
