As dawn breaks over the Ganges Delta, the humid air and golden sunlight weave a luminous veil over Dhaka, the vibrant heart of South Asia. From May 29 to 31, 2025, the RENEX-2025—the largest new energy event in South Asia—was grandly held at the Dhaka International Convention Center.
On this leading platform for energy transformation, Q-SUN showcased its high-efficiency N-type TOPCon PV modules and a comprehensive “PV + Energy Storage + Off-grid Control” integrated energy solution, making a powerful statement. The company also debuted its intelligent fully automated cleaning system designed for extreme heat and dust conditions, demonstrating its robust technical capability and innovation in the PV sector—injecting new momentum into Bangladesh’s green energy transition.
South Asia in Focus：An Urgent Call for Energy Transition
Bangladesh, one of the countries most vulnerable to the global climate crisis, faces pressing energy challenges: over 150 days of dust annually, summer temperatures exceeding 45°C, and a nationwide power deficit of up to 30%. In response, Q-SUN has developed a tailored solution targeting three major regional challenges: module power generation efficiency, intelligent cleaning efficiency, and off-grid energy storage reliability—offering a sustainable energy roadmap for tropical climates.
Core Technologies：Professional Solutions for Extreme Environments
Intelligent Fully Automated Cleaning System
To address performance degradation caused by dust accumulation, Q-SUN’s cleaning system activates daily high-pressure mist cleaning. With over 90% reduction in surface dust adhesion and a cleaning coverage rate of 98%, it ensures PV modules operate at peak efficiency under extreme weather.
MERCURY Series High-Efficiency Modules
Engineered for high irradiance and extreme heat, the MERCURY series—powered by advanced N-type TOPCon cell technology—offers a range of models (e.g., 585W to 710W), maintaining up to 23.2% conversion efficiency even in 50°C environments, highlighting excellent temperature coefficient performance.
Integrated Energy Solution for Heat and Dust
Combining MERCURY PV modules with Q-SUN’s smart energy storage and off-grid control systems, the integrated solution delivers 24/7 clean power supply, particularly suited for remote, weak-grid, and off-grid areas.
Looking Ahead：Empowering Tropical Sunshine with Technology
Driven by innovation and anchored in system integration expertise, Q-SUN continues to support South Asia’s energy transformation—from meeting basic survival needs to achieving high-quality sustainable growth. With every ray of tropical sunlight, Q-SUN seeks to convert natural resources into a long-term driver for development.
