Bank Loan for a Solar Power Plant
Last reviewed August 2026 · lenders, rates, DSCR, documents · every assumption stated
Lenders fund 70 to 75 per cent of a MW-scale solar project at 9.5 to 11 per cent over 10 to 13 years, against the project cash flows plus collateral. On a ₹4 crore 1 MW plant that is ₹2.8 to ₹3 crore of debt and ₹1 to ₹1.2 crore of your own money. The sanction turns on two things: a signed offtake arrangement and a debt service coverage ratio above about 1.25.
The bank is not lending against the panels. It is lending against a contract that says somebody will pay for the units. No offtake, no file — whatever the equipment.

The lending market
Six routes, and they are not interchangeable
The same project gets very different terms depending on where the file goes. The specialist lenders price better and move slower; the NBFCs do the opposite. Below about ₹10 crore of project cost, the bank you already hold accounts with is usually the realistic first conversation.
| Lender | Rate | Funding | Tenor | What to expect |
|---|---|---|---|---|
| IREDA | 9.0–10.5% | Up to 75% | 13–15 yrs | The sector specialist and the benchmark everyone else is measured against. Thorough appraisal, slow, and worth the wait on a large file. |
| NABARD, through a bank | 8.5–10.5% | Up to 75% | 10–13 yrs | Farmer, FPO and PM-KUSUM Component A projects only. Routed through a commercial or cooperative bank, not lent directly. |
| PFC and REC | 9.5–10.75% | 70–75% | 12–15 yrs | Built for utility-scale tickets. Below roughly ₹10 crore they rarely engage. |
| Public sector banks | 9.75–11.25% | 70% | 10–12 yrs | Will usually want collateral beyond the project. Fastest where you already bank and have a track record. |
| Private banks | 10–11.5% | 65–70% | 8–12 yrs | Quicker credit decisions, tighter covenants, and far more sensitive to who the offtaker is. |
| NBFCs | 11–13.5% | Up to 80% | 7–10 yrs | Higher leverage and speed at a real cost. Useful as a bridge, expensive as permanent debt. |
Rates are indicative for August 2026 and are quoted against each lender’s own benchmark plus a spread that depends on your credit and the offtake. Nothing here is an offer.
Debt sizing calculator
What the numbers have to look like before a lender says yes
Set the project and the loan you want. The calculator works out the debt, the equity you have to bring, the annual debt service and the coverage ratio — and tells you what a credit committee would do with it. Coverage, not capex, is what gets files declined.
Credit appraisal
How a credit committee actually reads a solar file
The appraisal is a series of questions about who pays and what happens if they pay late. Equipment brand comes up, but it is never the deciding item.
Who is the offtaker, contractually
A DISCOM with a regulator-approved tariff is the strongest paper and the slowest payer. A private consumer under open access pays faster and carries credit risk you have to underwrite. No signed contract means no file, however good the site is.
Coverage at the contracted tariff
Minimum 1.2 to 1.3, tested at the tariff in the contract and stressed for a P90 generation year and a payment delay. A ratio that only clears at an optimistic tariff will be cut back by reducing the loan.
Whose yield assessment is it
An energy yield report from the EPC contractor is a sales document. Lenders want P50 and P90 from an independent consultant, and increasingly a lender’s engineer review of the whole technical package.
Promoter capacity, not just net worth
Can you fund the equity, absorb a ten per cent cost overrun, and carry four months of receivables without the project stalling? That question sinks more files than the interest rate.
The sensitivity that matters most
Ask your own model what happens if generation comes in at P90 rather than P50, and the offtaker pays in 120 days rather than 45. If coverage stays above 1.1 in that case, the file is genuinely bankable. If it does not, the lender will find it, and the sanction will come back smaller than you asked for.
The sanction file
Eleven documents, and one of them is usually missing
Appraisal does not start when you submit; it starts when the file is complete. Sending it in pieces adds weeks, because each round of queries goes to the back of a queue.
Borrower and financials
- Project company incorporation documents, or the firm constitution if you are not using an SPV.
- Promoter KYC, net worth statements and existing borrowing position.
- Three years of audited financials for the promoter entity, plus provisional figures for the current year.
- A detailed project report with a 25-year financial model the lender can open and re-run.
- A sources and uses statement showing where the equity is coming from.
Project and technical
- Land title chain, encumbrance certificate, and the registered lease deed with an assignment clause if leased.
- Land classification position, and the conversion order where conversion was needed.
- Connectivity approval or the feasibility letter from the DISCOM, with the evacuation scheme.
- Signed offtake contract, letter of award or PPA, with the tariff and the payment terms.
- EPC contract with a bill of quantities, milestone payment schedule and performance guarantees.
- Independent energy yield assessment giving P50 and P90, plus module and inverter datasheets and warranties.
The item most often missing is the independent yield assessment, and the item most often weak is the land document set. What a bankable DPR contains, section by section.
Security and covenants
What the lender takes, and what it will stop you doing
Solar project debt is secured on the project and disciplined by covenants. None of this is unusual, but it is worth reading before signing rather than after.
First charge on project assets
Modules, structure, inverters, transformer, the switchyard and the receivables. Standard, and non-negotiable.
Land mortgage or lease assignment
If you own the land it is mortgaged. If you lease it, the lease must be registered and assignable to the lender, which is why an unregistered lease stops a file dead.
Escrow of receivables
Offtake payments land in an account the lender controls, with a defined waterfall: operating costs, then debt service, then a reserve, then you.
Debt service reserve
Usually three months of principal and interest, funded upfront or from early cash flow. It is real money out of the equity you budgeted.
Promoter guarantee and share pledge
Personal or corporate guarantee, and a pledge of the SPV shares. Expect both below ₹50 crore of project cost.
Covenants that bite
Minimum DSCR maintenance, no additional borrowing without consent, no change in shareholding, and a cost-overrun undertaking. Breaching the DSCR covenant can trap distributions even in a profitable year.
Timeline
Three to six months, if the file is complete
Disbursement is against milestones, not in one tranche, and the last tranche is usually released only after commissioning. Plan the construction cash flow around that.
Weeks 0–3
Preparation
Assemble the file, build the model, commission the independent yield assessment, and approach two lenders rather than one so there is a fallback.
Weeks 3–10
Appraisal
Credit analysis, technical review by the lender engineer, site visit, legal opinion on the land and the offtake contract, and rounds of queries.
Weeks 10–16
Sanction and documentation
Sanction letter with conditions precedent, loan agreement, creation of security, escrow account, insurance assignment. The conditions precedent list is where the last surprises appear.
Weeks 16 onwards
Disbursement
Released against construction milestones with the equity brought in first, and a final tranche after commissioning and the performance test.
Why files get declined
Six reasons, and five of them are paperwork
Almost nothing on this list is about the plant. Sort these before you approach a lender and the process is administrative rather than adversarial.
No signed offtake
An expression of interest, a draft PPA or a verbal assurance from a consumer is not an offtake contract. This is the single most common reason a solar file goes nowhere.
Land that cannot be secured
Unregistered lease, no assignment clause, a title chain with a gap, a public path through the parcel, or classification that still needs conversion.
Yield from the EPC contractor
A generation figure produced by the party selling you the plant will be discounted or rejected. Commission it independently and budget ₹1.5 to ₹4 lakh for it.
Coverage that only works optimistically
A ratio of 1.4 at a tariff you hope to get and 1.05 at the tariff you actually signed. The lender will use the signed one.
Thin promoter capacity
Equity funded from a source that is itself borrowed, no cushion for overrun, and no working capital for a four-month receivable cycle.
Cost outside the band
A capex materially above the market band without an explanation, or materially below it, which reads as a scope gap the lender will have to fund later.
Where we fit, and where we do not
We do not arrange finance, and we take no fee from any lender
Blues Renewables is an EPC contractor. We work at MW scale as a subcontract EPC and balance-of-system contractor inside other developer projects, and as a turnkey contractor at the rooftop and ground-mount sizes we have built. We are not a financial adviser, a loan agent or a broker.
What we can do on the technical side of your file
- Tell you whether the capex in your model sits inside the market band, and which line is off if it does not.
- Review the EPC scope and bill of quantities a lender will be shown, before it is shown.
- Explain what the evacuation package should cost so it is not the surprise that breaks the budget.
- Give you a defensible generation basis to take to an independent yield consultant.
What we will tell you to get elsewhere
- Debt arrangement, loan syndication or lender introductions.
- A bankable DPR and financial model, and a lender engineer to certify the technical package.
- An independent energy yield assessment with P50 and P90.
- Legal opinions on land, the offtake contract or the security package.
Send us the project, not the loan application
District, extent, capacity, who takes the power and the capex you have been quoted. We will come back in writing on whether the technical assumptions behind your model hold up. If they do not, better to know before a credit committee finds it.
If a vendor has offered to arrange the loan as part of the package, read the pricing carefully. Finance bundled into an EPC quotation is rarely cheaper than finance bought separately.
Solar plant finance, answered
Can I get a bank loan for a 1 MW solar power plant in India?
Yes. Lenders typically fund 70 to 75 per cent of project cost for a MW-scale solar plant, at 9.5 to 11 per cent over 10 to 13 years, against the project cash flows plus collateral. On a ₹4 crore 1 MW plant that is about ₹2.8 to ₹3 crore of debt and ₹1 to ₹1.2 crore of equity you have to bring. Two things decide the sanction: a signed offtake arrangement and a debt service coverage ratio above about 1.25 at the tariff in that contract.
Which banks and institutions lend to solar power plants?
IREDA and NABARD are the specialist routes, PFC and REC lend at scale, and public sector banks, private banks and NBFCs all have renewable energy products. IREDA and NABARD offer the best terms and the slowest process; NBFCs are the fastest and the most expensive. For a project below about ₹10 crore, your existing bank is usually the practical starting point because the relationship carries part of the credit assessment.
What interest rate applies to a solar power plant loan?
Between 8.5 and 13.5 per cent in 2026 depending on lender and structure. IREDA and NABARD-routed PM-KUSUM projects have run at 8.5 to 10.5 per cent, public sector banks at 9.75 to 11.25, private banks slightly higher, and NBFCs at 11 to 13.5. A one percentage point difference on ₹3 crore over 12 years is about ₹22 lakh, so it is worth negotiating, but tenor usually matters more than rate for the coverage ratio.
What is DSCR and why does it decide the loan?
Debt service coverage ratio is the cash the project generates in a year divided by the principal and interest due that year. Lenders want a minimum of about 1.2 to 1.3, and they test it at the contracted tariff, not at an optimistic one. If the ratio is thin the lender does not usually refuse outright; it reduces the loan amount, lengthens the tenor or asks for more collateral until the ratio clears. This is why the offtake contract, not the equipment, sets the loan size.
How much equity do I need to bring?
Twenty-five to thirty per cent of project cost, plus a cushion for cost overrun and the first few months of receivables. On a 1 MW plant that is ₹1 to ₹1.2 crore of equity and realistically ₹1.3 crore of cash. Land, if you are buying rather than leasing, usually sits outside the debt entirely, so a ₹40 lakh land purchase is ₹40 lakh of additional equity.
What documents does a lender ask for?
The project company documents and promoter KYC, three years of audited financials, a detailed project report with a financial model, complete land papers including title chain, encumbrance certificate and a registered lease if leased, the connectivity approval or feasibility letter, the signed offtake contract or letter of award, the EPC contract with a bill of quantities, module and inverter datasheets with warranties, and an independent energy yield assessment giving P50 and P90 numbers. The yield assessment being independent of the EPC contractor is not optional.
Is there a subsidy or interest subvention on solar plant loans?
Not as a general scheme at MW scale. PM-KUSUM Component A projects access concessional IREDA and NABARD refinance, and some state policies offer interest subvention for specific categories. Accelerated depreciation at 40 per cent in the first year is the significant tax benefit and it changes post-tax cash flow substantially for a profitable company, which lenders will model. Treat any lender or vendor promising a central capital subsidy on a MW plant as a warning.
How long does sanction and disbursement take?
Three to six months from a complete file to first disbursement, and longer if the file arrives incomplete. Appraisal takes four to eight weeks once every document is in, then sanction, then documentation and creation of security, then disbursement against milestones rather than in one tranche. The most common cause of delay is a land document or an offtake contract that is still being negotiated while the credit file is under appraisal.
