For factory owners, developers & IPPs

Services · EPC

Engineered, procured and built under one accountable contract.

Q: How long does a 1 MWp rooftop EPC take?

Typically 16–18 weeks from signed contract to commercial operation. Equipment lead time and utility approvals are the swing factors; we start filings in week two so they run in parallel with procurement.

Q: Can my factory roof take the load?

Most RMG and industrial roofs can, but we never assume. Every project starts with a structural survey; a typical rooftop array adds 12–15 kg/m². Where purlins fall short, we design strengthening or a lighter layout before quoting.

Q: Who handles net-metering and grid approvals?

We do. We prepare and file the SREDA net-metering application and the distribution utility's connection paperwork, and attend inspections through to meter installation.

Q: What warranties do we get?

OEM product and performance warranties on modules and inverters, registered in your name, plus our own workmanship warranty on the installation. Terms are set out in the contract per project.

Q: Do you take EPC-only contracts for developers and IPPs?

Yes. We deliver EPC-only scopes under your owner's engineer or lender's technical adviser, with hold points and reporting to match their requirements.

One team takes your plant from structural survey to grid synchronisation — with a named engineer, a written deliverable at every stage, and nobody else to blame if it underperforms.

Equipment sourcing partners

Vendor-neutral. Tier-1 only.

We don't sell one brand. We tender each project against bankable manufacturers and specify what fits your roof, your climate and your lender.

Bankable manufacturersBNEF Tier-1 modules and inverters with a lender-accepted track record.
Certified, locally testedIEC certificates plus test reports accepted by SREDA and the utility.
Service on the groundOEM service presence in Bangladesh, so warranty claims don't stall.

EPC case study

1.8 MWp hybrid rooftop for a knit composite plant

Result: 31%; lower grid bill
Sector: RMG & Textiles
Client: Knit composite manufacturer

The challengeThree sheds, 212,000 sq ft of corrugated roof, and six to nine hours of monthly load-shedding that stopped dyeing lines mid-batch. Diesel backup was costing more per unit than the grid.

The resultThe dyeing lines now ride through outages on battery, diesel runtime is down 78%, and the plant's monthly grid bill fell by 31% in the first full quarter.
