Tips for Finding the Best Loan for Solar Panel Options

Are the high power costs and frequent power cuts becoming a headache? Solar energy is the remedy you need! Solar power is an intelligent decision to lower electricity bills and adopt sustainability. Yet, the initial installation cost of solar panels is intimidating. An average 3 kW rooftop solar system runs from ₹1.5 lakh to ₹2 lakh, and a 5 kW system runs over ₹3 lakh. Not everyone can afford to pay this amount in one go. 

If the cost is causing you to give up on the idea of adopting solar panel systems, here’s the solution. With solar panel loan options, you can make this investment accessible.

In this blog, we will explore financing options, compare different loan offerings, learn about government subsidies, and offer tips to secure the best loan for your solar panel installation.

What is a Solar Panel Loan? 

Homeowners and businesses can now purchase and have solar energy systems installed without paying the entire amount upfront. This is made possible with a solar panel loan. A loan enables the borrowers to repay the amount over time instead of paying the entire installation fee upfront, making solar energy more affordable and within reach.

Let us try to understand with an example: 

Rahul, an Indian homeowner, was required to spend ₹3 lakh installing a 5 kW solar panel system. He chose to take out a bank loan for solar panels with a 5-year repayment period and 10% interest rate, rather than paying the entire cost upfront. 

Financial Breakdown:

• Total Cost: ₹3,00,000
• Government Subsidy: ₹72,000

(₹18,000/kW for the first 3 kW and ₹9,000/kW for the remaining 2 kW under the PM Surya Ghar Muft Bijli Yojana)

• Effective Cost After Subsidy: ₹2,28,000
• Loan Amount: ₹2,28,000
• EMI (approx.): ₹4,850/month for 60 months

Rahul got the system installed by an MNRE-approved vendor and registered through the National Rooftop Solar Portal. After installation, the local DISCOM installed a net meter. Through this meter, he could export excess electricity to the grid and receive credit on his bill.

Benefits Rahul Enjoyed:

• Monthly Savings on Electricity Bills: Approx. ₹3,500–₹4,000
• Reduced Carbon Footprint
• Return on Investment: Post loan repayment, Rahul gets nearly free electricity for 15–20 years
• Subsidy Credited Directly to His Bank Account
• Increased Property Value

Best Ways to Finance Solar Panel Installation

There are several ways to avoid an upfront cost and benefit from options:

A. Bank Loans for Solar Panels

Indian banks offer green energy loans tailored for home, business, and industrial solar installations. These loans feature:

• Low interest rates (8–12% per annum).
• Flexible payback plans
• Tax advantages under Section 80EEA of the Income Tax Act.

B. Online Loans for Solar Panels

Do you need funding that is easy and quick? NBFCs and fintech lenders offer quick online loans with easy application processes and little paperwork. Due to stringent credit conditions, these loans are appropriate for applicants who might not be eligible for conventional bank loans.

Top lenders include:

• Tata Capital
• My Mudra
• HDFC Bank

Interest rates range from 10–18% annually, offering faster approvals but higher costs compared to traditional bank loans.

C. Home Loan Top-Up for Solar Panels

Top-up loans are an option available to homeowners who have home loans actively running. A top up for solar panels helps with installations. Compared to personal loans, these loans usually feature longer repayment terms, less paperwork, and lower interest rates (7–10% annually).

Indian institutions that provide top-up loans linked to instant home loan include ICICI Bank, SBI, and HDFC Bank.

D. Solar Leasing & Power Purchase Agreements (PPA)

Want solar energy without upfront costs? Solar leasing or PPAs are the alternatives you need. Under these models:

• The solar company installs and maintains the panels with no initial investment.
• Customers can choose to pay monthly fees or for each unit of electricity produced.

E. Government Schemes & Subsidies

Through financial incentives, subsidies, and affordable loans, the Indian government actively encourages the use of solar energy:

1. Farmers who install solar pumps or power plants can receive subsidies under the PM-KUSUM Scheme 

2. Homeowners can get up to 40% subsidies under the Ministry of New and Renewable Energy’s (MNRE) Residential Rooftop Subsidy.

These initiatives substantially reduce installation costs. They make solar power accessible to small businesses and households.

Understanding Interest Rates on Solar Loans in India

Solar loan interest rates in India vary based on lender type, loan size, and repayment tenure:

1. Bank Loans: Typically 8–12% per annum, a good and stable source.

2. NBFC & Fintech Loans: Higher rates (10–18%) but quicker approvals and less documentation

3. Home Loan Top-Ups: Lowest rates (7–10%), the affordable option.

The ideal solar panel financing is one that is affordable, has a long tenure, and is easy to get approved. 

What Affects Solar Loan Interest Rates?

1. Credit Score: A high CIBIL score (>750) guarantees better (lower) interest rates.

2. Loan Tenure: Shorter loan terms result in higher EMIs but lower overall interest. Longer terms result in lower EMIs but higher overall expenses.

3. Lender Type: Compared to NBFCs or fintech lenders, banks often provide cheaper rates. Faster approvals are provided by fintech lenders.

Common Mistakes to Avoid When Financing Solar Panels

1. Overlooking Loan Terms & Fees

Always check for processing fees, prepayment charges, and hidden costs to avoid surprises.

2. Settling for a High-Interest Loan

Compare different banks, NBFCs, and fintech lenders to secure the best rate.

3. Missing Out on Government Subsidies

Many homeowners forget to apply for MNRE subsidies, leading to higher costs.

4. Compromising on Solar Panel Quality

Always choose BIS-certified solar panels for better efficiency and long-term durability.

Expert Tips to Get the Best Solar Loan

Want to finance your solar panels the right way? Here’s how to find the best loan:

1. Compare Interest Rates

Banks, NBFCs, and fintech lenders have different interest rates. Banks usually provide lower rates but may have a longer approval process. NBFCs and fintech lenders offer quicker approvals and often have minimal paperwork. Comparing options helps you secure the best deal.

2. Check Your Credit Score

A CIBIL score over 750 can help you get a lower interest rate. Lenders consider high scores a sign of responsible financial behaviour. To boost a low score, pay off debts, make timely payments, and lower credit usage before applying for a loan.

3. Pick the Right Tenure

Your loan tenure impacts your monthly EMI and total interest cost. A shorter loan term means higher EMIs. But, it reduces total interest, helping you pay off your loan faster. A longer tenure reduces your EMI but increases your pay over time. Choose a tenure that balances affordability and long-term savings.

4. Explore Government Schemes

The Indian government provides subsidies to help people adopt solar energy. For instance, MNRE (Ministry of New and Renewable Energy) gives subsidies. This support helps cut your initial costs. Some banks also provide green loans at lower interest rates. Checking for these incentives can help reduce your financial burden.

5. Check the Fine Print

Look over the terms and conditions before closing any loan. Watch out for hidden charges, processing fees, prepayment penalties, and late payment fees. Some lenders charge high fees for early loan repayment, which can impact your savings. Always clarify these details to avoid unexpected costs.

Compare many lenders, negotiate rates, and pick a plan that saves you the most in the long run!

Conclusion

Making the switch to solar energy has long-term financial benefits in addition to being an environmentally conscious move. Utilising government incentives and comparing interest rates offered by banks and lenders helps in choosing the best financing solution for your solar needs.
