Solar Panel on EMI in India 2026: Solar Loan, Subsidy, EMI and Complete Cost Guide

Solar panels can significantly reduce electricity expenses, but the initial installation cost can be a concern for many homeowners and businesses. The good news is that you do not always need to pay the entire solar installation cost from your savings.

In India, several banks and financial institutions offer solar loans or rooftop solar financing, allowing eligible customers to pay for their solar system through monthly EMIs. For residential consumers, financing can also be combined with the applicable PM Surya Ghar Muft Bijli Yojana subsidy, subject to the scheme rules and lender process.

This guide explains solar panel financing in India, solar loans, EMI options, subsidy, down payment, documents, loan tenure and important things to check before financing a solar system.

What Is Solar Panel Financing?

Solar panel financing means using a loan or other payment arrangement to fund the purchase and installation of a solar power system instead of paying the complete amount upfront.

For example, suppose a rooftop solar system costs ₹2 lakh. Instead of paying ₹2 lakh at once, an eligible customer may finance part of the project through a solar loan and repay the amount through monthly EMIs.

The exact loan amount, interest rate, tenure, margin, processing charges and eligibility depend on the lender and the applicant.

Some banks have dedicated rooftop-solar loan products. For example, Central Bank of India lists a PM Surya Ghar rooftop solar loan with financing options up to ₹2 lakh and higher loan limits under different eligibility conditions. Indian Bank also offers a PM Surya Ghar rooftop solar loan with repayment tenure of up to 10 years.

Why Are More People Looking at Solar Financing?

The biggest challenge for many solar buyers is not the technology—it is the upfront cost.

A homeowner may want to install a 3 kW or 5 kW solar system but may not want to use a large part of their savings for the installation.

Financing can help by spreading the project cost over several months or years.

Solar financing can help with:

• Lower upfront payment
• Monthly EMI-based repayment
• Better cash-flow management
• Possibility of using applicable solar subsidy
• Financing of eligible rooftop solar equipment and installation
• Longer repayment periods with some lenders

However, a loan also has an interest cost. Therefore, customers should compare the total repayment amount, not just the monthly EMI.

How Does a Solar Loan Work?

The basic process is relatively simple.

Step 1: Select your solar system

First decide the approximate solar capacity required for your home or business.

For residential customers, common rooftop solar sizes include:

• 1 kW Solar Panel
• 2 kW Solar Panel
• 3 kW Solar Panel
• 5 kW Solar Panel
• 10 kW and above, depending on requirements

Your electricity consumption, available roof area and technical feasibility should be considered before finalising the capacity.

Step 2: Get the project cost

The total project cost may include:

• Solar panels
• Inverter
• Mounting structure
• Cables and electrical equipment
• Installation
• Protection equipment
• Metering-related work
• Other site-specific requirements

The final price can vary depending on system capacity, equipment and installation conditions.

Step 3: Apply for financing

The customer can apply to a bank or financial institution offering a suitable solar loan.

The lender may evaluate factors such as:

• Applicant profile
• Income
• Credit history
• Electricity connection
• Roof ownership/right to install
• Project cost
• Solar system details
• Required loan amount

Requirements vary from one lender to another.

Step 4: Loan approval and installation

After approval, the lender's process determines how the financed amount is disbursed.

For example, Central Bank of India states that its rooftop solar loan can involve payment directly to the vendor/EPC contractor after installation and required verification.

Step 5: Repay through EMI

Once the loan is disbursed, the borrower repays the financed amount according to the agreed repayment schedule.

Solar Panel Loan vs Paying Cash

Before choosing financing, compare both options.

Factor	Cash Payment	Solar Loan
Initial payment	Higher	Lower upfront requirement possible
EMI	No	Yes
Interest cost	No	Yes
Savings used immediately	Higher	Lower
Monthly financial commitment	No	Yes
Flexibility	Depends on available savings	Depends on loan terms
Subsidy	Applicable if eligible	Applicable, but credit/disbursement process depends on lender
Total cost	Usually lower if no financing charges	Higher if interest/fees are added

There is no single payment method that works for every customer.

The right choice depends on available savings, loan terms, expected electricity savings and personal cash flow.

Can You Get a Solar Loan Under PM Surya Ghar?

Yes, eligible residential consumers can explore financing for rooftop solar under the PM Surya Ghar ecosystem.

The Central Government's rooftop solar programme provides financial assistance to eligible residential consumers. The current Delhi Solar Portal, for example, lists the central subsidy as ₹30,000 per kW up to 2 kW and ₹18,000 per kW for additional capacity up to 3 kW, with the total subsidy capped at ₹78,000 for systems above 3 kW.

The important point is that subsidy and loan are two different things.

A subsidy reduces the effective project burden for an eligible consumer, while a loan provides financing that must be repaid according to the lender's terms.

How Much Subsidy Can You Get on a 3 kW Solar System?

For eligible residential consumers under PM Surya Ghar, the central subsidy structure is:

Solar Capacity	Central Subsidy
1 kW	₹30,000
2 kW	₹60,000
3 kW	₹78,000
Above 3 kW	Maximum ₹78,000

Important:

₹78,000 is the Central Government subsidy.

It should not automatically be described as the total subsidy available in every state. State-level incentives can be different.

Example: How Solar Financing Can Work for a 3 kW System

Let's take a hypothetical example.

Suppose:

Solar system cost = ₹2,00,000

If the customer is eligible for:

Central subsidy = ₹78,000

Then the remaining project amount after subsidy would be:

₹2,00,000 − ₹78,000 = ₹1,22,000

If the customer finances ₹1,22,000, the loan repayment would depend on the interest rate and tenure offered by the lender.

For example, if a lender offers a 5-year loan, the EMI will be different from a 7-year or 10-year loan.

This is only an illustration. Actual EMI depends on the lender's interest rate, loan amount, fees and repayment tenure.

Solar Loan EMI Example

You can use the following formula to understand how EMI works:

EMI = [P × R × (1+R)^N] / [(1+R)^N − 1]

Where:

• P = Loan principal
• R = Monthly interest rate
• N = Number of monthly instalments

For example, if you finance ₹1,20,000, the EMI will change significantly depending on whether the loan is taken for 3, 5, 7 or 10 years.

A longer tenure can reduce the monthly EMI but may increase the total interest paid over the entire loan period.

So, don't choose a solar loan only because its EMI looks low.

Always check the total repayment amount.

What Is the Interest Rate on a Solar Loan?

There is no single solar-loan interest rate applicable to every customer in India.

The rate can depend on:

• Bank or financial institution
• Credit profile
• Loan amount
• Loan tenure
• Applicant category
• Existing relationship with the lender
• Type of solar project
• Applicable lender scheme

For example, current bank products show different structures. Central Bank of India directs applicants to its latest applicable interest rates, while other lenders publish their own solar-loan pricing and eligibility conditions.

Therefore, an article or vendor quoting one universal "solar loan interest rate" for everyone can be misleading.

Always verify the rate directly with the lender before signing the loan agreement.

How Long Can You Take a Solar Loan?

Loan tenure depends on the lender.

Some current rooftop-solar loan products allow repayment over several years. For example:

• Central Bank of India lists a maximum tenure of 120 months for its specified rooftop solar loan structure.
• Indian Bank also lists a maximum tenure of 120 months, including a moratorium period, under its PM Surya Ghar rooftop solar loan.
• Other lenders can have different repayment periods.

A longer tenure can make monthly payments easier but can increase total interest.

What Documents Are Usually Required for a Solar Loan?

The exact requirements depend on the lender, but applicants may be asked for documents such as:

• Aadhaar or other identity proof
• PAN card
• Address proof
• Latest electricity bill
• Income proof
• Bank account details
• Roof ownership/right-to-use information
• Solar quotation
• Solar system/project details
• Photographs or other technical documents, where required

For example, Central Bank of India lists a latest electricity bill and rooftop rights among its eligibility conditions for the specified solar loan.

Always check the lender's latest document checklist before applying.

Who Can Apply for a Solar Loan?

Eligibility varies between lenders.

For residential rooftop solar, a lender may consider:

• Salaried individuals
• Self-employed individuals
• Homeowners or eligible property users
• Applicants with suitable credit profiles
• Applicants meeting the lender's income criteria
• Applicants with a valid electricity connection

Some lenders may have specific requirements related to CIBIL score, income, roof rights or bank account relationship.

For example, Indian Bank's current PM Surya Ghar solar loan information includes eligibility conditions such as individual applicants, rooftop rights and a latest electricity bill; it also specifies income requirements for systems above 3 kW.

Can the Solar Subsidy Be Used With a Loan?

In eligible cases, yes, but the exact mechanism depends on the scheme and lender.

Some lenders specify that the subsidy can be credited to the loan account.

For example, Central Bank of India states that the borrower can claim the subsidy by providing the loan account number for credit of the subsidy amount into the loan account.

Canara Bank similarly states that applicable central financial assistance can be credited to the loan account under its housing-cum-solar loan structure.

This is why buyers should ask the lender one important question:

"How will my solar subsidy be adjusted against my loan?"

What Is Better: Short-Term or Long-Term Solar Loan?

Consider this simple difference:

Shorter tenure

Advantages:

• Higher monthly EMI
• Lower overall interest in many cases
• Loan gets paid off faster

Longer tenure

Advantages:

• Lower monthly EMI
• Easier monthly cash-flow management

Disadvantage:

• Total interest can be higher

For this reason, compare both EMI and total repayment, rather than selecting the longest tenure automatically.

Solar Loan vs EMI From a Solar Company

Customers may come across two different financing routes:

1. Bank/NBFC solar loan

You borrow money from a financial institution and repay it through EMIs.

2. Vendor-linked EMI/finance option

A solar installer may facilitate financing through a financial partner.

The important thing is to understand who is actually providing the finance.

Before signing, ask for:

• Lender name
• Interest rate
• Loan amount
• Processing fee
• GST/other charges
• Tenure
• Prepayment conditions
• Total repayment amount
• Subsidy adjustment process
• Insurance requirements, if applicable

Never assume that "EMI available" means zero-interest financing.

What Should You Check Before Taking a Solar Loan?

Before signing any financing agreement, check these points carefully.

1. Interest rate

Ask whether it is fixed or floating and how it can change.

2. Total repayment

Calculate the total amount you will pay over the full loan period.

3. Processing fee

Some products may have zero processing fees, while others can charge a fee.

4. Down payment or margin

Some lenders require the borrower to contribute part of the project cost.

For example, Central Bank of India's published terms show different margin requirements depending on the loan category.

5. Prepayment charges

Check whether you can repay the loan early without a penalty.

6. Subsidy adjustment

Ask exactly when and how the subsidy will be credited.

7. Insurance

Some lenders may require insurance for the financed solar equipment.

8. Vendor requirements

Check whether the lender requires installation through a particular empanelled or approved vendor.

9. Technical approval

Make sure the proposed system meets applicable technical and DISCOM requirements.

10. Final project price

Compare the financed quotation with the actual equipment and installation scope.

Is Solar on EMI Worth Considering?

For a customer who wants rooftop solar but does not want to pay the entire installation cost upfront, financing can be a useful option to evaluate.

However, the decision should be based on the complete financial picture:

Solar cost + financing cost − applicable subsidy − expected electricity savings

For example, a lower EMI does not automatically mean a cheaper loan. A longer repayment period can increase total interest.

Similarly, a higher EMI may reduce the total interest cost if the loan is repaid faster.

Solar Financing for Homes vs Businesses

Financing requirements are different for residential and commercial projects.

Residential Solar

Homeowners generally look for:

• Small rooftop systems
• PM Surya Ghar subsidy
• Lower loan amounts
• Monthly EMI
• Electricity bill savings

Commercial & Industrial Solar

Businesses may require much larger systems and different financing structures.

For example, Union Bank's current Union Solar product is designed for MSMEs/business enterprises and supports rooftop or ground-mounted solar projects for captive consumption.

Commercial projects can also use specialised financing, term loans, leases or other structures depending on project size and business requirements.

Therefore, a residential 3 kW solar loan should not be compared directly with financing for a large commercial solar plant.

7 Mistakes to Avoid When Taking a Solar Loan

Mistake 1: Looking only at EMI

A ₹5,000 EMI may look affordable, but check the total repayment.

Mistake 2: Ignoring the subsidy process

Understand whether the subsidy is credited to your bank account or adjusted against the loan.

Mistake 3: Choosing a loan only because it has a long tenure

Longer tenure can increase the total interest cost.

Mistake 4: Not checking processing charges

Read the complete fee schedule.

Mistake 5: Not checking prepayment rules

You may want to close the loan early if your financial situation improves.

Mistake 6: Comparing only the solar panel price

The complete system includes more than panels.

Mistake 7: Signing without checking the final quotation

Make sure the quotation clearly mentions equipment, capacity, installation and other charges.

How to Reduce the Cost of Your Solar Installation

Financing is only one part of the overall cost.

You can also reduce your effective solar cost by:

• Choosing the right system capacity
• Checking applicable government subsidy
• Comparing multiple quotations
• Understanding the equipment included
• Selecting an appropriate inverter
• Checking warranty terms
• Comparing financing offers
• Avoiding unnecessary add-ons
• Evaluating long-term electricity savings

The cheapest quotation is not necessarily the best quotation if it uses different equipment or excludes important installation components.

Conclusion

Solar financing in India can make rooftop solar more accessible for customers who do not want to pay the complete installation cost upfront.

The most important thing is not simply finding the lowest EMI. You should compare:

Solar System Cost + Interest + Fees − Applicable Subsidy − Expected Electricity Savings

Before taking a solar loan, check the lender's latest interest rate, tenure, margin, processing fee, prepayment rules and subsidy adjustment process.

For residential customers, the PM Surya Ghar subsidy can significantly reduce the effective cost of an eligible rooftop solar system, with the current central subsidy capped at ₹78,000 for systems above 3 kW.

If you are planning to install solar, first determine the right system capacity, compare the complete project cost and then evaluate whether cash payment, solar loan or EMI-based financing fits your budget.

Note: Solar subsidy rules, lender interest rates, eligibility conditions and financing products can change. Always verify the latest terms with the official government portal and the concerned lender before making a financial commitment.
