How net-metering works under the SREDA 2018 guideline (revised in 2025), what mills, factories, hospitals and universities in Bangladesh need to size a rooftop plant, payback maths, and a step-by-step approval flow with DPDC, DESCO, REB, BPDB and NESCO.
Bangladesh imports a meaningful share of its primary energy and the industrial tariff for medium-voltage consumers has steadily climbed since 2022. For mills, hospitals and universities with a usable roof, an on-grid net-metering solar system is now the most reliable way to lock in electricity costs for the next 25 years. This guide explains how the scheme works in 2026, what to size, how the maths play out, and the exact approval steps with the relevant utility (DPDC, DESCO, REB, BPDB or NESCO).
Under the Net Metering Guidelines 2025 (Power Division, administered by SREDA), eligible consumers — both single-phase and three-phase — can install rooftop solar of up to 100% of their sanctioned load (80% of transformer capacity for MV consumers) and feed surplus generation back into the grid. The utility nets imported and exported energy on the bill, and any surplus at the end of the financial year is settled at the prevailing BERC bulk-purchase rate. The customer keeps a single bi-directional meter and the same connection — no separate license is required.
Bangladesh's mid-latitude climate produces roughly 105 kWh per kWp per month on a well-oriented south-facing tilt, with monocrystalline modules from Tier-1 OEMs. A clean rule of thumb: every 1,000 sq ft of usable, shadow-free roof can host about 13 kWp of PV. The table below shows how that scales for typical Bangladesh facilities.
| Facility type | Usable roof | Plant size | Yearly generation | Yearly bill saving (BDT 10/kWh) |
|---|---|---|---|---|
| Garments factory | 60,000 sq ft | 780 kWp | 9,82,800 kWh | BDT 98,28,000 |
| Jute / textile mill | 45,000 sq ft | 585 kWp | 7,37,100 kWh | BDT 73,71,000 |
| Tertiary hospital | 30,000 sq ft | 390 kWp | 4,91,400 kWh | BDT 49,14,000 |
| University block | 20,000 sq ft | 260 kWp | 3,27,600 kWh | BDT 32,76,000 |
| Cold-storage shed | 100,000 sq ft | 1,300 kWp | 16,38,000 kWh | BDT 1,63,80,000 |
These are first-pass numbers — the real design must account for sanctioned load, transformer rating, roof orientation, shading, structural capacity (PSC vs corrugated metal), and the local utility's transformer headroom. Vvon's engineers run a full SLD plus structural and shadow analysis before quoting capacity.
On a typical industrial rooftop project in Bangladesh, the levelised cost of solar electricity is now well below the medium-voltage industrial tariff. The two flagship case studies Vvon engineered in the last three years illustrate the range:
| Case study | Capacity | Yearly generation | Yearly saving | ROI | CO₂ reduction |
|---|---|---|---|---|---|
| Akij Agro Feed Ltd. (Narayanganj) | 1,503 KWp | 18,96,660 kWh | BDT 2,01,04,500 | ≈ 3.5 years | 1,150 t / yr |
| Ahad Jute Mills Ltd. (Jashore) | 575 KWp | 7,31,500 kWh | BDT 77,54,000 | ≈ 4 years | 445 t / yr |
Beyond payback, the residual life of a Tier-1 PV plant is 25–30 years — meaning roughly two decades of effectively-free electricity once the capital is recovered. That is why net-metering has become the default capex decision for Bangladesh's larger industrial groups.
Vvon Technologies Limited has delivered 7+ MWp of industrial rooftop solar across Bangladesh, including the 1,503 KWp Akij Agro Feed plant in Narayanganj and the 575 KWp Ahad Jute Mills plant in Jashore. We are an authorized partner of Jinko Solar, Canadian Solar, JA Solar, Solis, Growatt, Sunways, Huawei and Schneider Electric — and we run an in-house engineering, EPC and O&M team based in Baridhara, Dhaka.
