Solar Panel Prices in Bangladesh (2026)
SREDA Net Metering Guidelines, IDCOL Concessional Financing & Industrial RMG Rooftop SolarDriven by industrial energy decarbonization across the export ready-made garment (RMG) sector and rising commercial power rates from BPDB, DESCO, and DPDC, solar PV adoption is expanding rapidly across Bangladesh. Wholesale Grade-A Tier-1 panel prices currently trade between ৳ 26.00 and ৳ 30.00 per Watt in major distribution centers in Dhaka (Motijheel, Nawabpur), Chittagong, and Gazipur.
1. Bangladesh Electricity Landscape & Industrial Rooftop Solar Shift
Bangladesh's manufacturing economy relies heavily on consistent electrical power. However, domestic natural gas reserve depletion and fluctuating imported LNG costs have prompted regular upward adjustments in retail power tariffs. Commercial and industrial electricity tariffs across DESCO, DPDC, and BREB service zones range between ৳ 9.80 and ৳ 12.50 per kWh.
To comply with global ESG mandates from international apparel buyers (requiring carbon footprint reductions for European and American retail chains), hundreds of RMG textile mills in Narayanganj, Savar, Gazipur, and Chittagong are transforming vast metal factory roofs into multi-megawatt captive solar power generators. With average daily solar irradiance of 4.8 to 5.2 peak sun hours, rooftop solar provides a proven mechanism to cut diesel generator reliance and lower operating costs.

4. SREDA Net Metering Guidelines & IDCOL Concessional Loans
The Sustainable and Renewable Energy Development Authority (SREDA) published the Net Metering Guidelines under which 3-phase electricity consumers of BPDB, DESCO, DPDC, WZPDCL, NESCO, and BREB can connect rooftop solar systems to offset peak tariff bills:
Key Regulatory Provisions:
- Capacity Cap: Solar PV capacity can be installed up to 70% of the consumer's sanctioned electricity load (capped at 3 MW for industrial consumers).
- Settlement Mechanism: Exported units are adjusted against imported units in monthly billing cycles. Surplus credits roll over month-to-month until the end of the settlement year.
- IDCOL Green Financing: Infrastructure Development Company Limited (IDCOL) provides long-term concessionary financing (tenure up to 10 years at low interest rates) for industrial RMG and commercial rooftop solar installations.
5. Financial Payback & Return on Investment in Bangladesh
For commercial buildings and factories operating during daylight hours, rooftop solar eliminates top-tier electricity consumption. With capital costs averaging ৳ 62 to ৳ 68 per Watt, payback periods range from 3.2 to 4.2 years for industrial users, and 3.8 to 4.8 years for residential consumers.
Case Study: 50 kW Industrial Setup in Gazipur / Narayanganj
- Total Turnkey Capital Cost: ৳ 3,150,000
- Annual Electricity Generation: ~78,000 kWh (units) / year
- Annual Bill Savings (@ ৳10.80/unit industrial tariff): 78,000 × ৳10.80 = ৳ 842,400 / year
- Calculated Payback Period: ৳ 3,150,000 ÷ ৳ 842,400 = 3.74 Years
- 25-Year Cumulative Savings: Over ৳ 22,000,000
- Levelized Cost of Energy (LCOE): ৳ 2.20 per unit (compared to grid rate of ৳ 10.80/unit).
6. Engineering & Maintenance Guidelines for Bangladesh
- Optimal South Tilt Angle: Install modules facing True South (180°) at a fixed tilt of 22° to 24° in Dhaka, Gazipur, and Sylhet, and 20° to 22° in Chittagong and Cox's Bazar.
- Tin Roof Mounting (RMG Factories): For corrugated metal roofs (sandwich panels / Kliplok sheets), use non-penetrative aluminum clamps to preserve factory roof waterproofing.
- Heavy Monsoon Waterproofing & Drainage: Heavy seasonal rains require robust IP65/IP66 enclosures for AC/DC combiner boxes and elevated cable tray routing.
- Chemical Grounding Pit: Keep earth resistance strictly below 5 Ohms to protect inverters from lightning strikes common during pre-monsoon thunderstorms (Kalbaishakhi).
