1. What is EMI for Solar Power Systems?

EMI (Equated Monthly Installment) is the fixed payment amount a borrower makes to a lender each month for solar power system purchases financed through credit cards. It includes both principal and interest components.

2. How Does the Calculator Work?

The calculator uses the standard EMI formula:

Where:

• \( P \) — Principal loan amount (solar system cost)
• \( R \) — Monthly interest rate (APR ÷ 12)
• \( N \) — Loan tenure in months

Explanation: The formula accounts for compound interest over the loan period, distributing payments equally across all months.

3. Importance of EMI Calculation

Details: Calculating EMI helps solar power buyers understand their monthly financial commitment, compare financing options, and plan their budgets accordingly.

4. Using the Calculator

Tips: Enter the total solar system cost as principal, your credit card's APR, and desired repayment period. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical APR for solar financing?
A: Credit card APRs for solar purchases typically range from 12% to 25%, depending on creditworthiness and card type.

Q2: Are there better options than credit cards?
A: Solar loans or PACE financing often offer lower rates than credit cards for solar installations.

Q3: How does tenure affect EMI?
A: Longer tenures reduce EMI but increase total interest paid. Shorter tenures have higher EMIs but lower total cost.

Q4: Are there prepayment penalties?
A: Most credit cards allow prepayment without penalties, which can save on interest costs.

Q5: What's included in the principal amount?
A: Include all solar system costs - panels, inverter, installation, permits, etc. minus any down payment.
