Bangladesh Net Metering Guidelines 2025 (Official Directive)
Detailed technical regulations governing rooftop solar interconnection, maximum 70% transformer capacity limits, bi-directional smart meter rollback, and billing cycle credits.
How a Hybrid Solar System Works
Engineered for seamless 24/7 reliability in Bangladesh. Capturing clean sunlight, powering your daily load, charging battery storage, and exporting surplus units to the national grid through SREDA-compliant bi-directional Net Metering.
Captures radiant solar irradiance and generates direct current (DC) electricity with up to 22.8% module efficiency.
The smart brain routing clean power between appliances, battery storage, and the national grid with micro-second transfer.
Stores daytime surplus energy in Tier-1 Lithium (LiFePO4) battery packs for silent, continuous nighttime power.
Exports excess solar energy directly into the BPDB/NESCO/DESCO grid to offset monthly billing under SREDA guidelines.
Key Net Metering Guidelines at a Glance
Summary of official regulatory standards enforced by the Sustainable and Renewable Energy Development Authority (SREDA) for commercial, industrial, and institutional rooftop solar plants.
| Regulatory Parameter | Official SREDA Standard | Utility Distribution Scope |
|---|---|---|
| Maximum System Sizing | Up to 70% of Sanctioned Load / Transformer Rating | Applies to BPDB, DPDC, DESCO, BREB, NESCO |
| Allowed Interconnection Level | LT 400V (Three-Phase) or HT 11kV / 33kV | Based on client substation voltage class |
| Inverter Certification | IEC 62116 / IEEE 1547 (Anti-Islanding Protection) | Automatic disconnect during utility grid failure |
| Bi-Directional Settlement | Net kWh unit adjustment per monthly billing cycle | Rolled forward annually per distribution code |
| Net Bangla Turnkey Scope | 100% Turnkey EPC • SREDA & Utility Approvals | Complete SLD, structural vetting & commissioning |
