20MW Rooftop Project in Chittagong, Bangladesh

 SAFETY DESIGN 

Safety Design: Arc Fault Circuit Interrupters (AFCI) are configured, which can detect and cut off faulty circuits in 0.1 seconds; the typhoon fastening system uses high-strength aluminum alloy brackets, with wind resistance up to 16 levels, and has passed the UL3703 safety certification. This reflects how professional engineering services and quality engineering services ensure not only stability but also long-term reliability in solar projects.

 Project Details and Achievements 

• Coverage Scenario: The project is distributed on the roofs of 20 industrial factories (accounting for 70%) and 5 commercial buildings in Chittagong, with a total area of about 180,000 square meters. It utilizes idle space to achieve "self-generated and self-used, surplus electricity for grid connection." Such integrated project solutions are a benchmark for solar engineering company practices, helping enterprises with efficient real estate development and sustainable project solutions.
• Energy Efficiency: The annual power generation is 32 million kilowatt-hours, of which 80% is used by the factories (mainly for production line power), resulting in a 38% decrease in electricity costs; the surplus electricity is connected to the local grid, providing clean electricity for residents around. This demonstrates how electrical engineering, power engineering solutions, and custom engineering solutions can directly reduce operating costs while contributing to community energy security.
• Safety Guarantee: In the past 2 years of operation, no safety accidents have occurred. The AFCI has issued 12 warnings for potential arc faults, and there has been no equipment damage during the typhoon season (May to October), making it a demonstration project for rooftop photovoltaic safety standards in Bangladesh. With the support of engineering consulting services and outsourced engineering services, the project showcases how an engineering services company can combine construction project management services with service engineering to deliver reliable solar system project outcomes. It further highlights the role of integrated engineering and architectural engineering in ensuring resilience and long-term success.

This rooftop solar system project stands as a model for project development services, construction project management solutions, and professional engineering services in South Asia. By integrating power engineering, project management services, and solar engineering expertise, it not only achieves energy efficiency but also sets a precedent for future sustainable infrastructure and integrated project solutions worldwide.
