Solar & Renewable Energy
Bangladesh's trusted solar EPC partner — on-grid, off-grid and hybrid PV from 1 kWp to utility scale with Growatt inverters, JA Solar / Jinko panels, net metering, PPA and rooftop-lease options.
What's included
On-grid, off-grid and hybrid solar EPC from 1 kWp to utility scale — site assessment, system design, supply of quality components (Growatt inverters, JA Solar and Jinko Tiger-Neo N-type panels), installation, testing, grid-tie commissioning and performance monitoring. Sustech also offers PPA (Power Purchase Agreement) and rooftop-lease models for zero-upfront solar adoption.
Reference projects include WFP Bhashanchar, Commonwealth War Graves Commission in Chittagong, Eastport Cumilla (100 kWp), and CUET — spanning industrial, humanitarian, heritage and institutional sectors.
Solar energy is the foundation of Sustech's commitment to clean, cost-effective power for Bangladesh's industrial sector — reducing grid dependence, lowering electricity costs, and contributing to national renewable energy targets.
Standards & methodology
PV systems are engineered to IEC 61215 / 61730 (modules), IEC 62548 (array design) and IEC 60364-7-712 (PV installations), in line with BNBC and DESCO/BPDB net-metering requirements. All installations comply with SREDA guidelines for grid-connected systems in Bangladesh.

Frequently asked questions
- How long does a 50 kWp system take?
- Typically a few weeks from design to commissioning, depending on site readiness and net-metering approval.
- What is the ROI on solar in Bangladesh?
- Most industrial rooftop systems pay back within a few years through grid-electricity savings — we provide a feasibility report with your numbers.
- Do you handle DESCO/BPDB net-metering?
- Yes — our scope covers design, documentation and coordination through to net-metering and grid-tie commissioning.
