Solar EMI Options Compared: Banks, NBFCs & Installer Plans

Four types of EMI options exist for solar installations in India: bank solar loans (7–10%, up to 10 years), NBFC financing (10–14%, up to 5 years), installer zero-cost EMI (0% for 6–24 months), and credit card EMI (12–18%, 3–12 months). The best option depends on your budget: if you want the lowest monthly payment, choose a long-tenure bank loan; if you want zero interest cost, choose an installer's 0% EMI plan.

Bank solar loans offer the lowest interest rates and longest tenures, making them ideal if you want the smallest possible monthly payment.

Best for: Homeowners who prefer low monthly outgo and can wait 7–15 days for approval

Pros:

• Lowest interest rates (7–10%)
• Longest tenure (up to 10 years with SBI)
• No collateral for amounts up to ₹10 lakh
• Subsidy integration — many banks factor in expected subsidy

Cons:

• Longer processing time (7–15 days)
• Documentation requirements (income proof, bank statements)
• CIBIL score of 650+ required

Non-banking financial companies (NBFCs) like Bajaj Finserv, Tata Capital, and L&T Finance offer solar financing with faster approval but higher rates.

Best for: Self-employed individuals, those with lower credit scores, or anyone who needs quick approval

Pros:

• Approval in 2–3 days (sometimes same day)
• More flexible income verification
• Lower CIBIL requirement (600+)
• Online application with minimal paperwork

Cons:

• Higher interest rates (10–14%)
• Shorter tenure (typically 3–5 years)
• Processing fees may be higher (1–2%)

Many solar installers offer 0% EMI plans where you pay the system cost in equal monthly instalments with no interest or extra charges.

Best for: Homeowners who can handle higher monthly payments (₹4,500–₹9,500/month for a 3kW system) for 12–24 months

Pros:

• Zero interest — total cost equals system price
• Instant approval — no bank paperwork
• Simple NACH mandate setup
• No CIBIL check in most cases

Cons:

• Short tenure (6–24 months) means higher EMI
• Available only through participating installers
• May not be available during all periods

Always verify that the total amount paid equals the quoted price with no hidden charges.

If your installer accepts credit card payments, you can convert the transaction to EMI through your card issuer.

Best for: Small systems (1–2kW) or if you plan to repay within 3 months

Why it is usually not recommended:

• High interest (12–18%) compared to solar loans (7–10%)
• EMI conversion fee of 1–2%
• Blocks your credit limit
• Short tenure (3–12 months)

For a 3kW system, credit card EMI costs ₹9,500–₹21,000 more than a bank solar loan over the same tenure. Only use this option if no other financing is available or for very small amounts.

Use this flowchart:

1. Can you pay ₹9,000+/month for 12 months? → Choose installer 0% EMI. Best total value.
2. Is lowest EMI your priority? → Choose SBI solar loan (7-year). EMI as low as ₹1,690 for 3kW.
3. Need approval within 2 days? → Choose NBFC financing (Bajaj Finserv, Tata Capital).
4. Self-employed with irregular income? → Choose NBFC or installer EMI. More flexible requirements.
5. CIBIL below 650? → Choose installer 0% EMI (no credit check) or NBFC with relaxed norms.

Regardless of which option you choose, your solar system saves you money from day one in most cases — the EMI is typically less than or equal to your current electricity bill.
