Bangladesh's RMG sector spends billions on electricity annually. Rooftop solar with net-metering can cut factory energy bills by 35–45%, improve LEED/green certification scores, and satisfy international buyer sustainability requirements — here is how.
Bangladesh's ready-made garment (RMG) sector employs over 4 million people and generates more than USD 45 billion in annual export earnings. It also consumes a significant portion of the national electricity supply. With international buyers increasingly demanding green manufacturing credentials — and electricity tariffs rising — rooftop solar is now a strategic imperative for RMG factory owners.
A typical mid-size RMG factory (500–1,000 workers) consumes 200,000–500,000 kWh per month. A 500–1,000 kWp rooftop solar plant can offset 30–50% of that consumption during daylight hours, directly reducing the monthly electricity bill. Beyond cost savings, solar installations contribute to LEED, EDGE, and BGMEA Green Factory certification — which is increasingly required by H&M, Zara, Primark, and other major international buyers.
| Factory size | Monthly consumption | Recommended plant | Monthly saving | Annual saving |
|---|---|---|---|---|
| Small (200 workers) | 80,000 kWh | 200 kWp | BDT 2,52,000 | BDT 30,24,000 |
| Medium (500 workers) | 200,000 kWh | 500 kWp | BDT 6,30,000 | BDT 75,60,000 |
| Large (1,000 workers) | 450,000 kWh | 1,000 kWp | BDT 12,60,000 | BDT 1,51,20,000 |
| Mega (2,000+ workers) | 900,000 kWh | 2,000 kWp | BDT 25,20,000 | BDT 3,02,40,000 |
Most RMG factories in Bangladesh use corrugated metal sheet (CGI) roofs on steel trusses. These are generally suitable for solar mounting with clamp-based racking systems that do not require roof penetration. Vvon's structural engineers assess the truss spacing, purlin capacity, and wind load before finalizing the mounting design. Factories with pre-engineered steel buildings (PEB) are particularly well-suited for large-scale solar.
