For Bangladesh's energy-intensive commercial and industrial facilities, escalating utility grid tariffs combined with seasonal gas transmission constraints have transformed captive solar from a sustainability luxury into a core operational necessity. However, a successful rooftop installation begins long before panel mounting—it demands a rigorous engineering feasibility assessment.
Commercial rooftops across Dhaka, Gazipur, Narayanganj, and Chattogram vary dramatically in construction. Reinforced concrete (RCC) flat roofs offer ample structural load capacity, but industrial pre-engineered steel buildings (PEB) require precise dead-load and wind-uplift verification under the Bangladesh National Building Code (BNBC 2020).
"Engineering due diligence on day one protects thirty years of facility operations. A solar array should never compromise roof waterproofing or structural safety."
Sub-tropical irradiation profiles across Bangladesh yield an average specific generation of 1,350 to 1,480 kWh per installed kWp annually. Using calibrated PVsyst 3D digital twins, Greenery EPC models near-field shading from nearby textile exhaust stacks, water reservoirs, and parapet walls to optimize row-to-row pitch and tilt angles.
The third pillar of feasibility is the facility's existing medium-voltage (11kV or 33kV) electrical infrastructure. Under SREDA Net-Metering Guidelines, the grid-tied inverter output connects directly to the plant's Low-Tension (LT) busbar. The local distribution utility—whether BREB, DPDC, DESCO, or BPDB—requires bi-directional digital metering, anti-islanding protection relays, and dedicated grounding grids under 1.0 Ohm impedance.
