Wind-Photoelectric Hybrid Street Light Project – 1500 Units in Thailand
Thailand has long been pursuing sustainable energy goals, especially in remote regions where grid electricity is unreliable or unavailable. In coastal and rural areas with strong seasonal winds and abundant sunshine, the Thai government aimed to implement a clean energy solution that ensures reliable street lighting without increasing the carbon footprint.
Queneng was selected to provide a wind-photoelectric hybrid solution, leveraging its advanced technology, all-in-one design, and proven performance in tropical and monsoon-prone environments.
