Solar Panel Loan in India 2026: Eligibility, Bank Documents, Interest Rates, EMI, Subsidy and Application Process

1. What Is a Solar Panel Loan?

A solar panel loan is a loan provided by a bank or financial institution to help customers pay for installing a solar power system.

Instead of paying the entire installation cost from your savings, you can borrow money from an eligible lender and repay it through monthly instalments called EMIs.

For example, imagine that your home solar installation costs ₹2,00,000.

You may be able to pay a portion of the cost from your savings and apply for a bank loan to cover the remaining amount. If your loan is approved, the bank may release the funds according to its rules and the installation requirements.

You then repay the loan every month over the agreed repayment period.

Main benefits of a solar panel loan:

• You do not need to pay the entire installation cost upfront.
• You can spread the cost over several years.
• You may qualify for a special residential rooftop solar loan.
• Eligible systems may receive government subsidy support.
• Solar electricity can help reduce your monthly electricity bill.

However, remember that loan approval is not guaranteed. The bank will check your eligibility, documents, and other conditions before approving your application.

2. Does the Government Provide Solar Loans?

The government supports residential rooftop solar through the PM Surya Ghar: Muft Bijli Yojana.

This scheme aims to help eligible households install rooftop solar systems and reduce their dependence on electricity purchased from the grid.

The scheme includes Central Financial Assistance (CFA), commonly called a solar subsidy. Eligible households may also access special bank loan products designed for rooftop solar installations.

According to a Government of India announcement published on 28 July 2026, eligible households can access collateral-free loans through nationalised banks at a concessional interest rate linked to the repo rate plus 50 basis points. The announcement cited a rate of 5.75% per annum at that time, with a repayment period of up to 10 years. Actual availability and rates should be confirmed with the participating bank because interest rates and lending conditions can change.

Important difference: Loan and subsidy

A solar loan and a government subsidy are two different things.

Solar loan: Money borrowed from a bank that must be repaid according to the loan agreement.

Solar subsidy: Financial assistance provided by the government to eligible beneficiaries under the applicable scheme conditions. It is not a loan and does not need to be repaid when the beneficiary complies with the scheme rules.

Receiving a subsidy does not automatically mean that your bank loan will be approved. Similarly, getting a loan does not automatically guarantee subsidy approval.

3. How Much Solar Subsidy Can You Receive?

Under the standard PM Surya Ghar residential subsidy structure for eligible installations in Tamil Nadu and other states, the Central Financial Assistance is calculated according to the eligible system capacity and applicable scheme rules.

Solar system capacity	Standard central subsidy
1 kW	₹30,000
2 kW	₹60,000
3 kW	₹78,000
Above 3 kW	Maximum ₹78,000 under the standard residential structure

The standard subsidy structure provides ₹30,000 per kW for the first 2 kW and ₹18,000 for the additional 1 kW. The central subsidy is generally capped at 3 kW for an eligible residential installation.

For example, an eligible household installing a 3 kW rooftop solar system may qualify for ₹78,000 in central subsidy, subject to the scheme’s current rules and successful verification.

A system larger than 3 kW does not automatically receive additional central subsidy under this standard structure.

Please remember: These figures relate to the standard residential subsidy. Eligibility, approved installation capacity, vendor requirements, commissioning, and other conditions must be checked before making a final decision.

Official information: PM Surya Ghar – Government of India

Can the subsidy be used to repay the solar loan?

Depending on the applicable bank product and scheme process, the subsidy may be credited to the beneficiary’s designated bank account or loan account.

Some bank products require the borrower to provide loan account details so that the subsidy can be credited towards the outstanding loan.

Ask your bank how the subsidy will be handled before signing the loan agreement. Do not assume that the subsidy will be available before installation or that it will immediately reduce your monthly EMI.

4. Which Banks Provide Solar Panel Loans?

Several banks in India offer residential rooftop solar financing products. The exact loan terms depend on the bank, the product, and the applicant’s eligibility.

Examples include:

1. Indian Bank

Indian Bank offers a PM Surya Ghar rooftop solar loan product. Its published terms distinguish between installations up to 3 kW and installations above 3 kW up to 10 kW.

2. Bank of India

Bank of India offers the STAR Rooftop Solar Panel Finance Loan for eligible individuals and certain housing societies.

3. Central Bank of India

Central Bank of India offers a rooftop solar loan product for eligible residential customers, subject to its stated eligibility and documentation requirements.

You can check the official pages here:

• Indian Bank – PM Surya Ghar Rooftop Solar Loan
• Bank of India – STAR Rooftop Solar Panel Finance Loan
• Central Bank of India – Rooftop Solar Loan Scheme

Before applying, compare the interest rate, margin contribution, repayment period, processing fees, required documents, and subsidy procedure.

A bank’s published scheme may not be available to every applicant or at every branch under identical conditions.

5. What Is the Maximum Solar Loan Amount?

The loan amount depends on the bank and the solar system you plan to install.

For example, Indian Bank publishes the following broad limits for its PM Surya Ghar rooftop solar loan product:

Installation category	Published maximum loan amount
Up to 3 kW	₹2 lakh
Above 3 kW up to 10 kW	₹6 lakh

These are the published limits of that particular bank product, not a promise that every customer will receive the maximum amount.

The approved amount may depend on the project cost, your contribution, income requirements where applicable, credit assessment, roof rights, and the bank’s final verification.

For a larger system, you should ask the bank whether its residential solar product covers the proposed capacity. Commercial and industrial solar projects may require different financing arrangements.

6. Who Is Eligible for a Solar Panel Loan?

Eligibility varies from bank to bank. However, the following conditions are commonly relevant to residential rooftop solar financing.

1. Indian resident

The applicant generally needs to meet the bank’s citizenship and residency conditions for the chosen loan product.

1. Eligible homeowner or person with roof rights

The applicant must have the legal right to install the solar system on the proposed roof.

If the property belongs to a family member, joint owner, or housing society, the bank may ask for additional consent or supporting documents.

1. Valid electricity connection

The latest electricity bill is important because it helps establish the service connection and the proposed installation location.

For Chennai customers, the electricity service details and applicable TANGEDCO/TNPDCL procedures should be checked as part of the installation process.

1. Acceptable credit history

The bank may check your CIBIL score or other credit information.

For example, certain published solar loan products specify a CIBIL score of 680 or above. This is not a universal requirement for every bank.

A lower score does not automatically mean every lender will reject you, but it can affect eligibility and the available loan terms.

1. Sufficient repayment capacity

The bank may consider your salary, income, existing loans, monthly commitments, or other financial information.

Some special solar loan products have simplified income documentation requirements. Other products require income proof, especially for higher loan amounts.

1. Suitable roof and technical feasibility

The proposed roof should be suitable for installing the system. The bank or relevant authorities may require technical or site feasibility checks.

1. Compliance with scheme conditions

If you want to apply under PM Surya Ghar, you must meet the scheme’s eligibility requirements and follow the applicable registration, vendor, installation, and commissioning procedures.

7. What Documents Are Required for a Solar Loan?

This is one of the most important questions customers ask before applying.

The exact list depends on the bank and loan category. Prepare the following documents and ask the selected bank for its final checklist.

1. Identity proof

The bank may request one or more of the following:

• Aadhaar card
• PAN card
• Passport
• Voter ID
• Driving licence

PAN requirements depend on the particular loan product and amount. Do not assume that every bank follows the same rule.

1. Address proof

Commonly accepted documents may include:

• Aadhaar card
• Passport
• Voter ID
• Driving licence
• Recent electricity bill
• Another address proof accepted by the bank

The bank may request separate proof of identity and address.

1. Latest electricity bill

Keep a recent electricity bill ready.

The bill helps the bank verify the service connection and the installation address. The applicant’s name and service details may also be checked.

If the electricity connection is in a deceased family member’s name, a landlord’s name, or another person’s name, ask the bank and electricity distribution company what additional documents are needed.

1. Solar quotation

Obtain a detailed quotation from your selected solar vendor.

The quotation should clearly mention:

• Solar system capacity in kW
• Solar module details
• Inverter details
• Mounting structure
• Electrical accessories and protection equipment
• Installation and commissioning charges
• Total project cost
• Applicable taxes, if any
• Warranty details

A clear quotation helps the bank understand the proposed installation cost and equipment.

1. Vendor agreement

The bank may ask for an agreement between the customer and the solar installation company.

This can help establish the scope of work, project cost, payment terms, and responsibilities of both parties.

1. Technical feasibility report

Depending on the bank and scheme, a technical feasibility report may be required.

It may include information about the proposed system, equipment, roof suitability, and technical requirements.

1. Site feasibility report

The bank or relevant process may require a site feasibility report to confirm that the proposed installation can be carried out at the location.

1. Bank account details

Keep the following ready where required:

• Bank passbook or account statement
• Account number
• IFSC code
• Cancelled cheque, if requested
• Loan account details for subsidy processing, where applicable

The name and account details should be correct. Incorrect bank information may delay financial transactions.

1. Income documents, where applicable

Depending on the loan product, the bank may request:

For salaried customers:

• Recent salary slips
• Bank statements
• Form 16 or income tax documents, where applicable

For self-employed customers or business owners:

• Income tax returns, where applicable
• Bank statements
• Business or income-related documents requested by the lender

Some special residential solar loans have simplified income documentation requirements. Do not assume that income documents are never required.

1. Property or roof-right documents

The bank may request property ownership proof, roof rights, or consent documents, depending on the applicant and property.

For apartments and shared rooftops, housing society or association approval may be necessary.

1. Additional documents after installation

Depending on the lender and the scheme, additional documents may be required during or after installation.

Examples include a commissioning certificate, net-metering or technical approval records, installation photographs, or other proof requested by the bank or scheme portal.

Important: Do not assume that every document above is compulsory for every loan. The bank’s official checklist for your specific application is the final reference.

8. What Is the Interest Rate for a Solar Panel Loan?

The interest rate is the amount charged by the bank for lending money.

Some eligible rooftop solar loan products offer concessional interest rates. Other products may use home-loan-linked rates or different lending terms.

For example, the Government of India’s July 2026 announcement cited a concessional rate of 5.75% per annum at that time for the relevant collateral-free financing arrangement linked to the repo rate plus 50 basis points.

However, this rate should not be treated as a guaranteed offer for every customer.

The actual interest rate may depend on:

• The bank and selected loan product
• Current repo rate or applicable benchmark
• Credit assessment
• Loan amount
• Existing banking relationship
• Loan category and other bank conditions

Always ask the bank for the current rate in writing before accepting the loan.

Also check whether the quoted rate is fixed or floating and whether processing charges, insurance, or other applicable charges will increase the total cost.

9. How Much EMI Will You Pay Every Month?

EMI means Equated Monthly Instalment. It is the amount you pay to the bank every month to repay the loan.

Your EMI depends on three main factors:

1. Loan amount
2. Annual interest rate
3. Repayment period

Here is an illustrative calculation for a ₹2,00,000 loan at an assumed interest rate of 5.75% per annum.

Repayment period	Approximate monthly EMI
3 years	₹6,059
5 years	₹3,844
7 years	₹2,885
10 years	₹2,195

These are estimates based on a standard reducing-balance EMI calculation. They exclude additional charges and assume that the interest rate remains unchanged for the calculation period.

A longer repayment period generally reduces the monthly EMI but may increase the total interest paid over the loan’s lifetime.

Before choosing a repayment period, check whether the EMI fits comfortably within your household budget.

10. How to Apply for a Solar Loan Under PM Surya Ghar

The application process may vary depending on the bank and the available digital application route. The following steps provide a general guide.

Step 1: Check your electricity connection

Keep your latest electricity bill ready. Confirm that your consumer details and installation address are correct.

Step 2: Register on the official PM Surya Ghar portal

Visit the official portal:

www.pmsuryaghar.gov.in

Follow the current registration instructions and enter the required consumer and electricity distribution details.

Step 3: Choose an eligible solar vendor

Select a vendor who can carry out the installation according to the scheme requirements.

Discuss your electricity consumption, roof space, proposed capacity, equipment, project cost, and expected savings.

Step 4: Obtain a detailed quotation

Request a written quotation with the complete system specifications and installation cost.

Do not compare quotations only by looking at the final price. Equipment quality, warranties, safety, installation standards, and after-sales support also matter.

Step 5: Apply through the bank’s approved route

Check the official bank product and its current application instructions.

Some loan products may use Jan Samarth or another designated application route. Follow the route specified for your selected product rather than assuming that every bank uses the same process.

Step 6: Submit the documents

Provide the documents requested by the bank. Check spelling, address, consumer number, bank account details, and the consistency of the quotation.

Step 7: Wait for verification and approval

The bank may check your eligibility, credit history, project details, documents, and other applicable conditions.

If anything is missing, provide the requested information promptly.

Step 8: Confirm the loan sanction and payment conditions

Before proceeding, read the sanction letter and loan agreement.

Confirm the approved amount, interest rate, EMI, repayment tenure, applicable charges, disbursement process, and subsidy-related requirements.

Step 9: Complete the solar installation

The installation should follow the applicable technical and scheme requirements.

Complete the required approvals, inspection, commissioning, and net-metering steps where applicable.

Step 10: Complete the subsidy process

Follow the official scheme process for submitting the required information and receiving the subsidy.

Keep copies of the quotation, invoice, payment records, installation details, and relevant portal or bank acknowledgements.

Do not plan your finances on the assumption that the subsidy will arrive on a specific date unless the responsible authority has confirmed the status.

11. How Long Does Solar Loan Approval Take?

There is no single approval timeline that applies to every bank and applicant.

The time required may depend on:

• Whether all documents are submitted correctly
• Credit and eligibility verification
• Bank workload
• Site and technical feasibility
• Property or roof-right issues
• Electricity connection details
• Additional information requested by the bank

A complete application may be processed more smoothly than one with missing or inconsistent documents. However, no vendor should guarantee approval within a particular number of days without confirmation from the lender.

You can ask the bank for an application reference number and a status update if processing is delayed.

Remember that loan approval, loan disbursement, solar installation, net-metering completion, and subsidy credit are separate stages. Each may have its own timeline.

12. Can Apartment Owners Get Solar Loans?

Apartment solar financing depends on the type of project and the bank’s lending product.

There is an important difference between installing solar for an individual flat and installing a common rooftop solar system for the entire apartment building.

Individual household installation: An eligible resident may apply for a residential solar loan if the person meets the lender’s requirements and has the necessary roof rights.

Common-area solar installation: An apartment association or registered housing society may need a separate financing product. Bank of India, for example, publishes a rooftop solar loan offering that includes certain housing societies.

For common-area installations, the association should check:

• Whether the lender accepts the association as a borrower
• The required association registration documents
• Board or general-body approval
• Rooftop rights and permissions
• Electricity connection and common-area billing details
• Required contribution and repayment arrangements

The standard individual household subsidy should not automatically be assumed to apply to every apartment common-area project. Confirm the applicable subsidy and financing rules before preparing the proposal.

13. Can Business Owners Get Solar Loans?

Businesses can also explore financing for rooftop solar, but the loan product may differ from a residential PM Surya Ghar loan.

Shops, offices, factories, warehouses, and other commercial or industrial properties may need business loans, equipment finance, green-energy finance, or project finance.

The lender may request:

• Business registration documents
• PAN and GST details, where applicable
• Business bank statements
• Income tax returns and financial statements
• Property or ownership documents
• Solar project quotation
• Technical feasibility report
• Electricity bills and consumption details

The exact requirements depend on the lender and project size.

Important: PM Surya Ghar’s standard residential subsidy and residential loan conditions should not be assumed to apply to commercial and industrial solar installations.

14. What If Your Solar Loan Is Rejected?

A rejected application does not always mean that you can never obtain solar financing. First, ask the bank for the reason.

Common reasons may include:

• Low or insufficient credit score under the selected product
• Existing loan repayment issues
• Missing documents
• Incorrect electricity consumer details
• Property ownership or roof-right problems
• Insufficient repayment capacity
• Ineligible project capacity or installation category
• Incomplete technical information

You can take the following steps:

1. Ask the bank for the reason for rejection.
2. Correct errors or provide missing documents.
3. Check your credit report for inaccuracies.
4. Resolve outstanding repayment issues where possible.
5. Confirm whether a different eligible bank product is suitable.
6. Obtain an updated quotation or technical report if required.

Avoid submitting multiple applications without understanding the problem. Each lender may have its own credit assessment process.

Never pay an unknown agent who promises guaranteed loan approval or guaranteed subsidy release.

15. Is a Solar Loan Worth It?

A solar loan may make installation more affordable, but you should compare the EMI with your expected electricity bill savings.

For example, suppose your estimated monthly electricity savings are ₹2,500 and your monthly loan EMI is ₹2,195.

The difference is approximately ₹305 per month before considering maintenance, any changes in electricity charges, and other costs.

This is only an illustration, not a promise of savings. Actual solar generation and savings depend on system size, roof orientation, shade, weather, consumption patterns, electricity tariffs, and applicable billing arrangements.

Before applying for a loan, ask your solar vendor to explain the expected generation and savings using your actual electricity consumption and roof conditions.

You should also consider whether you can comfortably pay the EMI during months when your electricity savings are lower than expected.

16. Important Things to Check Before Signing a Solar Loan

Before accepting any loan offer, check the following:

• Is the lender and loan product genuine?
• What is the final sanctioned loan amount?
• What is the current interest rate?
• Is the rate fixed or floating?
• How much must you pay from your own savings?
• What is the monthly EMI?
• What is the total repayment amount?
• Are there any processing or other charges?
• Is collateral required under your selected product?
• How will the subsidy be processed?
• Can the EMI or outstanding balance change after the subsidy is credited?
• What happens if the installation or subsidy process is delayed?
• Are there any prepayment or foreclosure conditions?

Read the sanction letter carefully and keep a copy of the signed loan agreement.

Do not rely only on verbal promises made by a salesperson, vendor, agent, or bank representative.

Conclusion: Make Solar More Affordable with the Right Loan

Installing rooftop solar can help eligible households reduce their dependence on grid electricity and manage long-term energy costs. A suitable solar loan can make the initial investment easier to manage by spreading the cost over monthly instalments.

However, customers should understand the eligibility requirements, required documents, loan terms, and subsidy process before making a decision.

Under PM Surya Ghar, eligible residential customers may benefit from central subsidy support and suitable bank financing. The actual loan amount, interest rate, repayment period, and subsidy approval depend on the applicable rules and the lender’s assessment.

Kavin Solars encourages homeowners in Chennai to understand their electricity consumption, compare suitable solar options, and review the complete project cost before choosing a financing plan.
