Wind-Solar Hybrid Street Light Head with Dual Energy Supply, 12.8V Nominal Voltage, and IP67 Protection for Stable Outdoor Illumination

Product Introduction

This wind-solar hybrid street light head uses dual energy sources (solar + wind), making it suitable for areas with poor sunlight or abundant wind resources. Equipped with solar panels and a wind turbine, it generates power from solar by day and wind by night, ensuring complementary energy supply and normal operation even during cloudy/rainy periods.

Core Advantages

• Dual Energy Complementarity:​ Solar and wind power complement each other, improving energy efficiency and ensuring reliable lighting during extended cloudy periods.

• High Reliability:​ Dual energy sources provide backup; if one is insufficient, the other supplements, ensuring high power supply reliability.

• Strong Adaptability:​ Suitable for areas with poor sunlight or rich wind resources, such as mountainous regions, coastal areas, and high-latitude zones.

Product Parameters

Application Case

Case: Grassland Road Lighting Project in Inner Mongolia

Located in a grassland area of Inner Mongolia with average sunlight but abundant wind resources, the project installed Liwei hybrid street light heads (12.8V 100Ah battery, 100W solar panel, 300W wind turbine). The system utilizes solar by day and wind by night, ensuring normal lighting for up to 5 consecutive cloudy days. Over one year, it solved the grassland road lighting problem, saving about ¥1,200 annually on electricity costs.

Q&A

Q1: What are the configuration recommendations for the hybrid system?

A: Recommendations: 1) Areas with average sunlight/good wind: 100W solar + 300W wind + 100Ah battery; 2) Areas with poor sunlight/average wind: 150W solar + 200W wind + 120Ah battery; 3) Areas with good sunlight/average wind: 200W solar + 100W wind + 80Ah battery.

Q2: What are the installation requirements?

A: Requirements: 1) Solar panels face south, unshaded; 2) Wind turbine installation height recommended 6-8 meters, avoiding obstacles; 3) Ambient temperature between -20°C and 60°C; 4) Well-ventilated location away from direct sunlight.

Q3: Are maintenance costs high?

A: Maintenance costs are low. Solar panels last 25+ years, wind turbines 10+ years, lithium batteries 5+ years. Routine maintenance involves cleaning solar panels and checking the wind turbine blades.
