Three ways to fund an industrial rooftop solar plant in Bangladesh, what each does to your balance sheet, what a lender or ESCO will ask you for, and the roof and tenure questions that decide whether a deal closes.
Bangladesh's industrial electricity tariff has risen sharply since 2022. BPDB's HV industrial rate now exceeds BDT 10 per kWh including demand charges. A 500 kWp rooftop system can save BDT 5 to 7 million per year. Yet many factory owners hesitate because the upfront capital cost of BDT 35 to 50 million feels prohibitive. You do not need to pay that upfront. Several structured financing routes are available in Bangladesh in 2026, each with different risk profiles and cash-flow implications.
Several Bangladeshi commercial banks and development finance institutions offer green finance loans specifically for renewable energy projects. Bangladesh Bank's Refinancing Scheme for Green Products (RSGP) allows participating banks to refinance solar loans at subsidised rates. IDCOL (Infrastructure Development Company Limited) also provides direct project finance for industrial solar installations above 100 kWp.
The key advantage of a bank loan is that you own the system from day one and capture the full net-metering benefit. The key disadvantage is that it appears on your balance sheet as debt, which may affect your credit ratios. Note also the mismatch between a 5 to 7 year tenor and a plant that runs for 25 to 30 years: the debt is repaid long before the asset stops earning, which is good for lifetime economics but means the first few years carry the heaviest cash-flow burden. Compare the annual repayment against the annual saving before you sign, not the total interest against the total saving.
Under an ESCO arrangement, a third-party energy service company finances, installs and owns the solar system on your roof. You pay a monthly service fee, typically 80 to 90% of what you would otherwise pay BPDB for the equivalent units. The ESCO recovers its investment over a 10 to 15 year contract period, after which ownership may transfer to you.
What you are really buying is certainty in exchange for upside. The ESCO carries the capital, the performance risk and the maintenance obligation, and takes the difference between your service fee and the value of the energy produced. Read three clauses carefully before signing: what happens if you want to exit early and how the buyout is calculated, whether the fee is indexed to the utility tariff or fixed, and who is responsible if the roof needs repair and the array has to come off. That third question is the one that turns into a dispute, because the roof is yours and the array is theirs.
An operating lease is similar to an ESCO model but structured as a lease agreement rather than a service contract. The lessor, typically a leasing company or bank subsidiary, owns the equipment and you pay a fixed monthly lease rental. At the end of the lease term, typically 5 to 7 years, you may purchase the system at residual value or renew the lease. Operating leases are treated as off-balance-sheet financing under Bangladesh accounting standards, which is attractive for companies with tight debt covenants. The practical difference from an ESCO is that a lease rental is fixed regardless of how much the plant generates, so the performance risk sits with you rather than with the counterparty. That is worth less if the plant is well built and worth a great deal if it is not, which is why lease financing pairs badly with a lowest-price EPC contractor.
| Factor | Direct ownership (loan) | ESCO model | Operating lease |
|---|---|---|---|
| Upfront capital | Zero (loan covers it) | Zero | Zero |
| Balance sheet impact | Debt increases | Off-balance-sheet | Off-balance-sheet |
| Savings capture | 100% after loan repayment | 10 to 20% shared with ESCO | Partial |
| System ownership | Yours from day 1 | ESCO for 10 to 15 years | Lessor |
| Maintenance responsibility | Yours | ESCO's | Lessor's |
| Best for | Strong balance sheets | Cash-constrained factories | Short-term occupancy |
The appraisal is where timelines slip, almost always because the technical file and the financial file are being prepared by two groups who are not talking to each other. Assemble both before you approach anyone.
| Item | Who provides it | Why it is asked for |
|---|---|---|
| Three years of audited accounts | Owner's finance team | Establishes repayment capacity and covenant headroom |
| Twelve months of electricity bills | Owner | The saving being financed is derived from these, not from a generic tariff |
| Sanctioned load letter and transformer details | Owner | Caps the approvable plant capacity, and therefore the fundable project size |
| Proof of roof ownership, or lease deed with landlord consent | Owner | Nobody lends against an asset bolted to a roof the borrower may vacate |
| Board resolution authorising the borrowing | Owner | Standard sanction condition |
| EPC contract, BOQ and technical specification | EPC contractor | Lets the appraiser test whether the cost and the yield estimate are credible |
| Generation estimate and savings model | EPC contractor | Underwrites the repayment source; a model without a self-consumption split will be questioned |
| Net-metering NOC or approval letter | Owner signs, EPC prepares | Often a disbursement condition, since without it the plant cannot export or be billed on a netted basis |
| Insurance cover for the installed asset | Owner | Sanction condition; check the policy actually covers rooftop PV against storm damage |
The item most often missing is the net-metering approval, because owners assume it follows installation. Where a lender makes it a disbursement condition, an unapproved plant means a completed project with no drawdown. Confirm early which of your conditions are pre-disbursement and which are post-completion, and build the utility approval timeline into the drawdown schedule.
The right financing model depends on three factors: your balance sheet strength, your electricity consumption profile, and your building tenure. If you own your building and have a strong balance sheet, a direct bank loan gives you the best long-term economics. If you are cash-constrained or lease your premises, an ESCO or operating lease removes the capital risk entirely. There is also a case for saying no for now: if your daytime load is small relative to your roof, or your order book is volatile enough that the load could halve, a smaller self-funded plant sized to your firm daytime base is a better decision than a large financed one sized to the roof.
