Solar loan EMI calculator

Often, but not always, and the calculator shows which case you are in. When the bill you stop paying is larger than the instalment you start paying, the system is cash-positive from the first month. On a shorter tenure or a smaller bill it may not be, and there is a monthly gap until the loan ends.

A typical starting rate for rooftop solar lending, which you can move to your own lender's actual quote on the slider above. Your real rate depends on the lender, your credit profile and whether the loan is secured, so treat the default as a starting shape rather than a quote — a lender is the only party who can price it properly.

By default, yes — the loan is sized against the cost after the PM Surya Ghar subsidy, because most buyers finance what they actually expect to pay. Toggle the subsidy switch above to see the instalment on the pre-subsidy cost instead, useful if you want to see the gap the subsidy is bridging or plan for it being delayed.

It makes the instalment smaller and the total larger. Stretching the term is how you get the monthly figure under your current bill, but you pay more interest to do it. The total-interest figure moves as you change the slider so you can see the trade.

The combination that minimises total cost, not the one with the smallest monthly number — those pull in opposite directions. A larger down payment and a shorter tenure cost less overall but demand more upfront; stretching the tenure lowers the instalment but adds interest. What actually makes solar affordable is not underfinancing it: an undersized system to fit a smaller loan generates less and saves less every month for the next 25 years, which usually costs far more than a slightly larger instalment for a few years would have.
