Payback · financing
Banks, NBFCs, and portal-linked loan options can fund residential rooftop plants. CFA under PM Surya Ghar is still a separate DBT after commissioning — not an automatic EMI waiver. Borrow only after the bill maths clear.

Fast triage: concessional PM Surya Ghar path (~5.75%, Jan Samarth) is covered on PM Surya Ghar loan. This page is the India-wide EMI test: finance net after CFA, not brochure gross.
| Item | What it is | When you see it |
|---|---|---|
| Gross quote | Vendor price for panels, inverter, structure, labour | Before install |
| Central CFA | PM Surya Ghar DBT up to ₹78,000 for eligible 3 kW+ homes | After portal + DISCOM commissioning |
| Loan / EMI | Credit for net or gross cost, depending on lender structure | From disbursement until tenure ends |
Do not let a sales deck show EMI on the pre-subsidy price while verbally promising CFA will “cover itself.” Model: gross − expected CFA = amount you may finance, then compare EMI to your current bill savings. Scheme overview: PM Surya Ghar.
High slab bills, clear roof, eligible CFA path, and EMI comfortably below expected monthly savings leave room for buffer months (monsoon, commissioning delay). Prefer shorter tenure once CFA credits to your account if the lender allows prepayment without punitive fees.
Everything about financing a rooftop system reduces to a single comparison. Does the monthly instalment sit comfortably below the amount the plant actually removes from your electricity bill? If yes, the loan is buying you a cash-flow-positive asset. If no, you are converting an electricity bill into a slightly larger debt repayment, and you have made your position worse.
Do it in this order, and use your own quotation rather than these illustrative numbers.
Start from the net amount, not the gross. Take the gross quote, subtract the assistance you are genuinely eligible for, and finance what remains. On a 3 kW system quoted near ₹1,90,000 with a ₹78,000 ceiling, the amount in question is about ₹1,12,000 — not ₹1,90,000.
Then estimate the instalment. Over five years at rates typical of collateral-light rooftop lending, ₹1,12,000 tends to translate into an instalment somewhere in the region of ₹2,300–2,600 a month. Over seven years it falls, but total interest rises. Ask for the exact figure in writing along with the annual percentage rate.
Then estimate what the plant genuinely saves. This is where most people overstate the case. Do not take the installer's annual figure and divide by twelve. Work from the units the system will realistically generate at your location, price them at the slabs they actually displace, and then keep the fixed charges in your bill, because they will not disappear. The honest monthly saving is usually meaningfully below the brochure number.
Then compare, and leave headroom. If the instalment is ₹2,500 and the realistic saving is ₹2,900, the arrangement works but the margin is thin. If the saving is ₹1,600, it does not work, whatever the sales conversation implies. A useful discipline is to require the saving to exceed the instalment by a comfortable margin rather than by rupees, because generation is seasonal while the instalment is not.
Even when the comparison passes, the calendar can still hurt you. All three of these are cash-flow issues rather than economics, and all three are avoidable if you plan for them.
The instalment can begin before the plant generates. Disbursement, installation, inspection and meter replacement are separate steps with separate queues. It is entirely possible to owe two or three instalments before your first unit is exported. Ask when repayment begins relative to commissioning, and keep a small buffer for that gap.
Assistance arrives later than the loan. The credit reaches your bank account only after the process completes and the necessary verification is done, which is well after you have paid the vendor. If you have financed the gross amount in the expectation of prepaying once the money arrives, confirm in writing that the lender permits early part-payment without a punitive charge. Some do not, and then the assistance simply sits against interest you have already committed to.
Monsoon months undershoot. Generation is not level across the year. A plant that averages well can still deliver a weak few weeks, and the instalment does not adjust. Judge affordability against your weakest expected month, not the annual average.
Take these to the lender rather than the installer, and get the answers in writing.
Is the quoted rate reducing or flat, and what is the effective annual percentage rate? A flat rate that sounds lower is frequently more expensive. What are the processing, documentation and insurance charges, and are they added to the principal? Is any security or lien involved, and is it on the plant or the property? What is the prepayment charge, and does it change after a set period? Does repayment start on disbursement or on commissioning? And if the tie-up came through your installer, what is your own bank's offer for comparison — a vendor-arranged loan is convenient, not automatically competitive.
One further caution specific to solar: be wary of any arrangement where the financing and the equipment come from the same party with a single combined monthly figure and no itemised breakdown. You need to be able to see the plant cost and the credit cost separately, because otherwise you cannot tell whether you are overpaying for hardware, for money, or for both.
KYC, income proof, electricity bill, and sometimes property papers — overlapping with portal needs but not identical. Sealix does not process loans; we only help you read whether the underlying plant is worth financing. Apply steps: how to apply.

Finance the net amount. Take the gross quote, subtract the assistance you are genuinely eligible for, and borrow what remains. On a 3 kW system quoted near ₹1,90,000 with a ₹78,000 ceiling, the amount in question is about ₹1,12,000. Be cautious of any sales presentation that shows an instalment calculated on the pre-subsidy price while verbally promising the subsidy will cover itself.
Compare the instalment against what the plant realistically removes from your bill, not against the installer's annual savings figure. Estimate generation for your location, price those units at the tariff slabs they actually displace, and keep the fixed charges in your bill because they will not disappear. The saving should exceed the instalment by a comfortable margin, since generation is seasonal while the instalment is not.
Often earlier than people expect. Disbursement, installation, inspection and meter replacement are separate steps with separate queues, so it is possible to owe two or three instalments before the first unit is exported. Ask the lender whether repayment begins on disbursement or on commissioning, and keep a small buffer for that gap.
Only if your lender permits it without a punitive charge, so confirm this in writing before signing. The assistance reaches your bank account well after you have paid the vendor. If you financed the gross amount expecting to prepay and the agreement penalises early part-payment, the money simply offsets interest you have already committed to.
When your bill is low enough that savings cannot cover the instalment, when you are ineligible for assistance and financing a full retail quote, when shade or a small roof caps generation far below the quotation's assumptions, or when your remaining stay in a rented house is shorter than the payback period.
Whether the rate is reducing or flat and what the effective annual percentage rate is, since a flat rate that sounds lower is frequently more expensive. Also ask about processing, documentation and insurance charges and whether they are added to the principal, whether any security or lien applies and on what, the prepayment charge, and when repayment starts. If the tie-up came through your installer, compare it against your own bank's offer.
