Learn how to apply for a collateral-free solar loans via JanSamarth Portal, check eligibility, compare interest rates and understand subsidy benefits.

Imagine reducing your monthly electricity bill with rooftop solar without paying the entire installation cost upfront. For many Indian households, the biggest obstacle isn’t a lack of sunlight—it’s the initial investment. And when savings are limited, the idea of pledging property or other assets to secure a loan can make solar power seem out of reach.

The good news is that eligible residential consumers can explore collateral-free rooftop solar loans through the JanSamarth Portal, integrated with the National Portal for the PM Surya Ghar: Muft Bijli Yojana. The government has facilitated concessional financing through nationalised banks, helping eligible households spread the cost of a solar installation over time.

But there’s an important distinction: collateral-free does not mean guaranteed approval, zero interest or free solar installation. Your lender still assesses your application, and your repayment obligations remain even if your subsidy is delayed.

This guide explains how to apply, what documents to prepare, how interest and subsidies work, and what to check before accepting a solar loan in India.

What Is the JanSamarth Solar Loan?

JanSamarth is the Government of India’s National Portal for Credit-Linked Government Schemes. It connects eligible applicants with participating banks and financial institutions through a digital application process. The portal includes a dedicated Roof Top Solar Installation Financing scheme.

The solar financing journey is linked to the PM Surya Ghar: Muft Bijli Yojana, which supports eligible residential rooftop solar installations.

• PM Surya Ghar Portal: Register for rooftop solar and subsidy

What does collateral-free mean?

A collateral-free loan generally does not require you to pledge property, land or another asset as security for the loan.

However, the bank may still evaluate your income, credit history, repayment capacity and other eligibility conditions. Collateral-free financing is not the same as a loan without credit checks or repayment obligations.

Is this loan linked to PM Surya Ghar?

Yes. Eligible residential consumers can access solar financing through the integration between the PM Surya Ghar National Portal and JanSamarth. The loan and subsidy are separate parts of the overall process, each subject to the applicable rules.

Who Is Eligible for a Collateral-Free Solar Loan?

Eligibility depends on the specific bank’s loan product and the scheme rules in force. Before applying, check the following requirements.

Basic eligibility checklist

• You are an Indian resident applying for a qualifying residential rooftop solar installation.
• You have an active domestic electricity connection.
• You have the right to install solar panels on the proposed rooftop.
• Your proposed installation and vendor meet the applicable PM Surya Ghar requirements.
• You meet the selected lender’s age, KYC, income and credit assessment requirements.
• You have not already received an incompatible subsidy for the same installation.

Some banks may accept applications without a minimum CIBIL score for smaller loan amounts but require a minimum score and income proof for larger loans. For example, SBI publishes different criteria for loans up to ₹2 lakh and loans above ₹2 lakh up to ₹6 lakh. These are SBI-specific conditions, not universal JanSamarth eligibility rules.

Can salaried and self-employed applicants apply?

Potentially, yes. The lender’s product rules determine which applicants qualify and what income documentation is required.

• Salaried applicants: Keep salary slips, bank statements and employment details ready.
• Self-employed applicants: Prepare the income and business documents requested by the lender.
• Applicants without a long credit history: Ask whether the selected bank accepts first-time borrowers for the chosen loan amount.

Key Features of Collateral-Free Solar Loans via JanSamarth

• Collateral: Nil (unsecured) for loans typically up to ₹2 lakh. Larger amounts may involve hypothecation of the solar system itself rather than property mortgage.
• Loan amount: Generally up to ₹2–6 lakh depending on bank and system size (commonly aligned with systems up to 3–10 kW).
• Margin / Own contribution: Usually around 10% of project cost.
• Interest rates: Competitive; many public sector banks offer around 5.75%–7% for smaller tickets (rates are bank-specific and subject to change).
• Tenure: Up to 10 years (120 months) in most cases.
• Moratorium: Often 6 months from disbursement, giving time for installation, net metering, and subsidy credit.
• Disbursement: Usually directly to the empanelled vendor after verification.
• Processing: Digital-first with possible branch verification.

These features make the product significantly more affordable than a regular personal loan.

Benefits of a Collateral-Free Solar Loan

A loan can make rooftop solar accessible without requiring you to fund the entire project upfront.

No property collateral under the qualifying loan

You generally do not need to mortgage your house or pledge land as security for a collateral-free product. The lender may still retain a security interest in the financed equipment.

Concessional interest rates

The government reported a rate of 5.75% per annum at the prevailing rate stated in its July 2026 announcement, with a 10-year tenure for the specified nationalised-bank financing facility. Your actual offer and rate may differ by lender and loan product.

Digital application journey

The portal provides an online route to check eligibility, submit an application and follow the loan process, reducing the need for repeated bank visits.

Potential subsidy support

Eligible residential installations can receive central financial assistance under PM Surya Ghar, subject to scheme conditions and approval.

How to Apply for a Solar Loan Through JanSamarth

Follow these steps to apply for rooftop solar financing.

Step 1: Register on the PM Surya Ghar portal

Visit pmsuryaghar.gov.in and follow the registration process for your electricity connection. Keep your consumer account details and registered mobile number available.

Step 2: Review your installation requirements

Check your available rooftop area, electricity consumption and suitable system capacity. Review registered vendors and obtain a detailed quotation before committing to an installation.

Step 3: Open JanSamarth

Go to the official JanSamarth website. Find the rooftop solar financing scheme and start the relevant applicant journey.

Step 4: Complete the eligibility assessment

Enter the requested personal, electricity connection, installation and financial details. Answer accurately and review the loan amount and lender options shown by the portal.

Step 5: Submit the application and supporting documents

Upload or provide the documents requested by the selected bank. Save the application reference number and any acknowledgement.

Step 6: Wait for bank verification and sanction

An eligibility result or in-principle offer is not necessarily final approval. The bank may verify your information, request additional documents and issue final terms.

Step 7: Complete installation and subsidy formalities

Follow the bank’s disbursement instructions and the PM Surya Ghar installation, inspection and subsidy process. Confirm when your EMI starts and how the subsidy will be credited before signing the agreement.

Eligibility Criteria for a Collateral-Free Solar Loan

Core requirements generally include:

• Residential electricity consumer (DISCOM connection in your name or with proper ownership proof).
• Successful registration and preferably feasibility approval on pmsuryaghar.gov.in.
• Indian resident with valid Aadhaar and PAN.
• Acceptable credit profile (many banks look for CIBIL 650–700+ especially for higher amounts; smaller tickets can be more flexible).
• Demonstrable repayment capacity (salary slips, ITR, or other income proof).
• Age typically 21–65/70 years (bank-specific; co-applicant may be needed for senior citizens).

Exact criteria vary by lender. The JanSamarth eligibility checker and the individual bank’s product page provide the final filter.

Required Documents Checklist for a Collateral-Free Solar Loan

Prepare these in clear digital format (PDF/JPG):

• Aadhaar card (name must match electricity bill and bank records as closely as possible)
• PAN card
• Latest electricity bill (with consumer number)
• Income proof (last 3 months salary slips + Form 16 / ITR for last 2 years; or business documents for self-employed)
• Bank statements / passbook (last 3–6 months) and cancelled cheque
• PM Surya Ghar application / feasibility approval letter
• Vendor quotation from an empanelled installer
• Property ownership proof (sale deed, property tax receipt, khatauni, etc. — often requested by branches even if portal marks it optional)
• Passport-size photograph

Name consistency across Aadhaar, electricity bill, and bank KYC is one of the biggest causes of delays or rejection. Fix mismatches early.

Step-by-Step Application Process on JanSamarth Solar Loan

1. Register on PM Surya Ghar Portal
   Visit pmsuryaghar.gov.in → Consumer Login / Apply. Use mobile number + OTP, enter electricity consumer number, and complete the application. Select system size and preferred vendor later if needed.
2. Obtain DISCOM Feasibility Approval
   Your DISCOM verifies technical feasibility (load, roof suitability, etc.). This usually takes 15–30 days depending on the state and workload.
3. Create Account on JanSamarth
   Go to jansamarth.in. Use the same mobile number registered on the PM Surya Ghar portal for smoother verification.
4. Select the Solar Scheme
   Navigate to Renewable Energy → Roof Top Solar Installation Financing (SOLAR) or the PM Surya Ghar-linked option. Check eligibility.
5. Fill Application & Upload Documents
   Provide personal, income, and project details. Upload the required documents. Project details often auto-populate from the PM Surya Ghar application.
6. Select Bank / View Offers
   Review available lenders, interest rates, and terms. Choose one or more.
7. Bank Processing & Sanction
   The bank conducts its own checks (CIBIL, income verification, possible branch visit or video KYC). Digital in-principle approval may come first; final sanction follows.
8. Disbursement, Installation & Subsidy
   After sanction and installation/commissioning, the bank typically disburses to the vendor. Apply for subsidy on the PM Surya Ghar portal; it is usually credited via DBT (sometimes adjusted against the loan principal by certain banks).

Track status on both portals. Keep the JanSamarth application reference number handy for bank follow-ups.
