Direct answer: Karnataka homeowners financing a rooftop solar system usually choose one of two paths. (1) PM Surya Ghar collateral-free bank loan via the National Portal and Jan Samarth: MNRE has stated a concessional rate of repo rate + 50 basis points, i.e. 5.75% per annum for the present, with a 10-year tenure and collateral-free lending from nationalised banks (up to ₹2 lakh under the terms cited in a Lok Sabha reply of 12 August 2026). (2) Eltron Zero Cost EMI: our site offers 0% interest EMI in 6 instalments, facilitated by a third-party NBFC, with other tenures available on request.

Scheme loan vs installer EMI — comparison
| Point | PM Surya Ghar / Jan Samarth bank loan | Eltron Zero Cost EMI |
|---|---|---|
| Interest | Repo + 50 bps (5.75% p.a. for the present, per MNRE / PIB) | 0% interest on the EMI plan described on our site |
| Tenure | Up to 10 years | 6 instalments on the standard plan; other tenures offered via NBFC |
| Collateral | Collateral-free (MNRE); banks typically take hypothecation of the financed system | Installer EMI via third-party NBFC — ask us what the lender requires for your case |
| Who applies | You, on pmsuryaghar.gov.in, then Jan Samarth / the bank | Eltron helps start the NBFC EMI process with your quote |
| Typical amount framing | Lok Sabha reply cites collateral-free loan up to ₹2 lakh at the concessional rate; some nationalised banks also publish higher limits with income proof — confirm with the bank | Covers the amount on your Eltron quote after any subsidy adjustment you choose |
| Subsidy credit | Often credited to the loan account when you give the loan account number on the portal (cuts principal) | Subsidy still claimed via the National Portal after DISCOM inspection; path depends on how you pay |

How the PM Surya Ghar / Jan Samarth loan works
- Register on the National Portal (www.pmsuryaghar.gov.in) as a residential consumer with your BESCOM or GESCOM connection.
- Choose a portal-registered vendor and a system size. Subsidy homes need DCR panels.
- Apply for the loan from inside the portal journey; it integrates with Jan Samarth for in-principle approval, then the nationalised bank sanctions after its checks.
- Disbursement is typically paid to the registered vendor / EPC after feasibility and documentation, not as cash to you (bank product pages).
- Install, get inspected, claim subsidy. After BESCOM or GESCOM inspection, the subsidy can be credited to your bank or loan account. Full steps: PM Surya Ghar guide for Karnataka.
Who qualifies
- Residential grid-connected consumers applying on the National Portal (the scheme loan is for household rooftops, not shops or factories).
- Rooftop rights and enough clear roof area for the size you want.
- Active electricity connection with BESCOM (Bengaluru) or GESCOM (Ballari / Kalaburagi) and a recent bill.
- DCR modules if you want the central subsidy. See DCR vs non-DCR.
- Deadline awareness: the current scheme implementation period runs to 31 March 2027; inspection, not just application, unlocks the subsidy.
How much do you actually finance?
Use this structure — do not treat the blank as a quote:
Amount to finance ≈ system turnkey cost − PM Surya Ghar subsidy (if eligible) − any cash you put in
- Subsidy today for Karnataka homes: ₹30,000 per kW for the first 2 kW, ₹18,000 for the third kW, capped at ₹78,000 for 3 kW and above.
- Size-specific Bangalore prices live on our rooftop solar cost hub. We do not invent monthly loan EMIs here; your bank or our NBFC partner quotes those on the financed amount.
- GST on the invoice is separate — see GST on solar panels in Karnataka.
Why many buyers still use short 0% EMI
- Cash-flow: six interest-free instalments clear the balance quickly once the system is producing.
- Speed: the homepage EMI path is an NBFC process started with your Eltron quote, parallel to (not a substitute for) the portal subsidy filing.
- Longer bank loan: better when you want a lower monthly outflow over years and are comfortable with floating repo-linked interest and bank documentation.
- Neither path is a guarantee of approval. Credit checks and bank / NBFC rules still apply.
Plain advice: if you can clear a short 0% EMI from bill savings and cash buffer, it often costs less interest than a multi-year loan. If the upfront gap is large, the Jan Samarth route exists for that. We can map both against your bill.
Documents checklist (typical bank path)
Drawn from public nationalised-bank product pages for PM Surya Ghar loans (e.g. Bank of Baroda, SBI). Your branch may ask for more.

FAQ: solar loan and EMI in Karnataka
What is the PM Surya Ghar loan interest rate?
MNRE and PIB have stated a concessional rate of repo rate plus 50 basis points, i.e. 5.75% per annum for the present, with a tenure of 10 years, on collateral-free loans from nationalised banks. The rate is linked to the repo rate, so confirm the current figure with the bank before you sign.
How do I apply for a Jan Samarth solar loan?
First register and progress your rooftop application on the National Portal (www.pmsuryaghar.gov.in). The loan is then applied through the portal’s Jan Samarth integration (www.jansamarth.in). The bank sanctions after its own checks.
Is the PM Surya Ghar loan really collateral-free?
Yes, as stated by MNRE in PIB and Lok Sabha replies: collateral-free lending from nationalised banks. Banks still typically take hypothecation of the financed solar assets. That is different from mortgaging your house as collateral.
Does Eltron offer 0% EMI on solar in Bangalore?
Yes. Our homepage describes Zero Cost EMI: 0% interest, pay in 6 easy instalments, facilitated by a third-party NBFC, with other tenures available. Call +91 7975009078 for current options on your quote.
Can the subsidy be credited to my loan account?
Yes. Under the scheme process, the CFA can be released to your bank account or to the loan account when you provide the loan account number on the portal. That reduces the outstanding principal after DISCOM inspection and approval.
What documents do I need for a solar bank loan up to ₹2 lakh?
Public bank product pages for the scheme typically ask for KYC, the latest electricity bill and the Jan Samarth digital approval letter, and state that income documents are not required for the simplified band up to ₹2 lakh. Higher amounts need income proof. Confirm with your branch.
Should I take the 10-year bank loan or Eltron’s 6-instalment EMI?
If you want the lowest interest cost and can clear the balance soon, short 0% EMI is usually simpler. If you need a smaller monthly outflow over years, the Jan Samarth bank loan is built for that. We help you compare both against your bill and system size — neither is pre-approved.
