Bangladesh’s garment and textile factories sit on gigawatts of unused roof space while they buy grid power and burn diesel. This guide covers the potential, the cost against diesel, what buyers expect, the structural and approval barriers, and how to finance a factory rooftop system.
Lowest-bid, item-by-item purchasing works for pumps and cables — not for solar plants. How system thinking changes the specification, the comparison and the outcome, with a buyer’s checklist.

From the ground a rooftop array looks simple. Behind it sit zoning, clearances, tilt and azimuth, wind uplift, string design, shading, cable sizing and earthing — explained through a real-style design-review layout.
