Solar EMI calculator

Planning to finance your rooftop system? Choose the size and state to prefill the cost from UVR’s rate list, set a down payment, and enter the interest rate and tenure your lender has offered. You’ll see the EMI, total interest and how it compares with your expected monthly savings.

How it works

  1. System cost is prefilled from UVR’s rate list for your state and size; you can type your own amount instead.
  2. Choose whether to finance the full cost or the cost after subsidy, since the subsidy is credited only after commissioning.
  3. Loan amount = amount to finance − down payment.
  4. EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where r is the monthly rate and n the number of months.
  5. EMI is compared with estimated monthly savings of kW × 126 units × ₹8.5.

Assumptions

Frequently asked questions

What interest rate should I enter?

Enter the rate your bank or NBFC has actually quoted you. Solar loan rates depend on the lender, your credit profile, the loan amount and tenure, and they change over time, so this calculator does not assume one. The PM Surya Ghar national portal also lists loan products from participating banks that you can compare.

Should I finance the cost before or after subsidy?

The central subsidy is credited to your bank account after the system is commissioned, so many buyers fund the full cost upfront and use the subsidy to prepay part of the loan later. Switch between full system cost and cost after subsidy to see both scenarios, then confirm the structure with your lender.

How is the EMI calculated?

We use the standard reducing-balance formula: EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1). P is the loan amount, r is the monthly interest rate (annual rate ÷ 12 ÷ 100) and n is the number of monthly instalments. Total interest is the sum of all EMIs minus the loan amount.

Can solar savings cover my EMI?

Often they cover a large share, but it depends on the loan amount, rate and tenure. We estimate monthly savings as system size × 126 units × ₹8.5 per unit and compare that with the EMI. If savings exceed the EMI, the system is cash-positive from the first month; otherwise the gap is your net monthly outflow.
