Harnessing Solar Energy for Urban Needs
The newly installed solar streetlights, equipped with high-efficiency photovoltaic panels and lithium-ion battery systems, are designed to provide 12 hours of uninterrupted illumination daily. Each 40-watt LED fixture emits 4,000 lumens of brightness, ensuring visibility on roads, walkways, and public spaces. The 8-meter height optimizes light distribution, minimizing dark spots and improving security in densely populated neighborhoods.
“This initiative is a critical step in modernizing Dhaka’s infrastructure,” said DSCC Mayor Md. Fazle Noor Taposh at the inauguration ceremony. “Solar energy not only cuts electricity costs but also aligns with our goal to build a greener, safer city for future generations.”
Addressing Energy Challenges
Bangladesh, a nation vulnerable to climate change, has long grappled with power shortages and fossil fuel dependency. The solar streetlight project—funded by a collaboration between the Ministry of Power, Energy, and Mineral Resources and international development partners—aims to save an estimated 1,200 megawatt-hours of grid electricity annually. Over 500 units have already been installed in key zones, including Gulshan, Dhanmondi, and Old Dhaka, with plans to expand to 2,000 units by mid-2025.
Residents have welcomed the initiative. “These lights make a huge difference at night, especially for women and children,” said Rina Akhtar, a local shopkeeper. “The streets feel safer, and the reduced air pollution is a bonus.”
A Model for Climate Action
Experts highlight the project’s dual impact: slashing CO₂ emissions by approximately 800 tons per year while serving as a scalable model for other South Asian cities. Dr. Saleemul Huq, a climate scientist and director of the International Centre for Climate Change and Development, praised the effort: “Decentralized solar solutions are vital for low-carbon urbanization. Dhaka’s leadership sets a precedent for the region.”
The DSCC has also integrated smart features such as motion sensors and remote monitoring to optimize energy use. Maintenance teams will receive training to ensure long-term sustainability.
As dusk falls over Dhaka, the glow of solar-powered streetlights symbolizes a brighter, cleaner future—one where innovation and environmental stewardship light the way.
