How to Show EMI Options in a Solar Proposal

There is a moment in almost every residential solar sale where the customer hears the price, ₹1.6 lakh, ₹2.1 lakh, ₹2.5 lakh, and goes quiet. You can almost hear them doing the mental maths: "Where am I supposed to find ₹2.5 lakh?" The conversation shifts from excitement to avoidance. Follow-up calls get ignored. A strong lead goes cold.

The EPCs that close the most residential deals in India have figured out how to pre-empt that moment. They show the monthly cost before the customer ever sees the total price. They present ₹3,500/month, an amount that sounds less than most people's electricity bill, long before ₹2.5 lakh appears anywhere in the document.

This is the psychology behind the EMI section in a solar proposal, and this guide explains exactly how to build it.

Why the Lump-Sum Frame Kills Deals

Human beings are notoriously bad at evaluating large, infrequent purchases against small, recurring ones. This effect, called "payment decoupling" in behavioural economics research, is well-documented by peer-reviewed solar adoption studies: households consistently underestimate long-term energy savings when presented with upfront costs rather than monthly cost comparisons. A homeowner who pays ₹3,200/month on electricity without blinking will baulk at ₹1.8 lakh for solar, even though the solar system pays itself back in under five years and then generates free electricity for another twenty.

The problem is not the economics. The problem is the frame.

When a customer sees ₹1.8 lakh in a proposal, their brain compares it to other lump-sum items: a refrigerator, a car down payment, a child's tuition fee. It triggers loss aversion. The decision goes into "wait and discuss" mode, which is where deals die.

When the same customer sees ₹3,500/month, their brain automatically compares it to their current electricity bill of ₹3,200/month. The delta is only ₹300. Suddenly the conversation is: "So I pay ₹300 more for the next seven years and then I pay almost nothing for the next eighteen years?" That is a conversation that closes.

The EMI Calculation Formula Every Installer Should Know

EMI is calculated using the standard reducing-balance formula:

EMI = P × r × (1+r)ⁿ ÷ [(1+r)ⁿ − 1]

Where:

• P = Principal loan amount (gross system cost minus subsidy)
• r = Monthly interest rate = annual rate ÷ 12
• n = Number of monthly instalments (tenure in months)

Example, 3 kW system, SBI at 7%, 10-year tenure:

• Gross cost: ₹1,65,000
• Central subsidy (PM Surya Ghar): ₹78,000
• Net loan principal (P): ₹87,000
• Monthly rate (r): 7% ÷ 12 = 0.5833%
• Tenure (n): 120 months
• EMI = ₹87,000 × 0.005833 × (1.005833)¹²⁰ ÷ [(1.005833)¹²⁰ − 1]
• EMI ≈ ₹1,010/month

You do not need to do this calculation manually in every proposal. But you do need to understand the inputs so your EMI table is correct, and so you can explain the numbers when a customer asks. For a deeper dive on bank-specific rates and how PM Surya Ghar financing works, see the guide on PM Surya Ghar loan and EMI options.

Which Banks and NBFCs to Feature in Your Proposal

Not every bank is worth listing. Your proposal should feature the two or three lenders that are realistic options for most of your customers in your geography. Here is the current landscape for 2026:

For a full comparison of rates by bank and how PM Surya Ghar eligibility affects the loan, see solar loan interest rates India and the complete guide to solar financing partners in India. The MNRE rooftop solar portal publishes the official PM Surya Ghar empanelled bank list and current subsidy guidelines that inform these rates. The PM Surya Ghar national portal is where customers register and where the subsidy disbursement is tracked, make sure your customer is registered before presenting bank options.

How to Show Subsidy + EMI Together, The Net-of-Subsidy Table

The most effective EMI display in a proposal is the net-of-subsidy table. It shows the customer three numbers in one place: gross cost, subsidy deduction, and the resulting EMI. Here is the exact format:

This single table does something powerful: it gives the customer a choice instead of a verdict. Instead of staring at a fixed lump sum, they see three different monthly numbers and can pick what fits their budget. Customers who feel in control of a decision are far more likely to make one.

1 kW / 2 kW / 3 kW EMI Examples at Current Rates

Let's walk through the complete calculation for the most common residential system sizes in India, using 2026 rates and the standard MNRE benchmark cost of ₹55,000/kW for Tier 1 panels.

1 kW System, The Entry Point

Total cost: ₹55,000 | Subsidy: ₹30,000 | Net principal: ₹25,000

• SBI, 7%, 7 years: ₹380/month, ideal for customers with a ₹1,500–₹2,000 electricity bill who want the lowest possible outgoing
• Bank of Baroda, 8.4%, 7 years: ₹398/month
• Tata Capital, 11%, 5 years: ₹543/month, suitable when CIBIL is below 700

At ₹380–₹398/month, the conversation becomes: "You currently pay ₹1,500 on electricity. After installing 1 kW, your bill drops to roughly ₹800 and you pay ₹380 EMI. Your total monthly spend on electricity is ₹1,180, a saving of ₹320 from month one." According to Central Electricity Authority (CEA) data, average residential tariffs in India have risen 6–8% annually over the past five years, meaning the saving compounds every year the tariff increases.

2 kW System, The Most Common Residential Choice

Total cost: ₹1,10,000 | Subsidy: ₹60,000 | Net principal: ₹50,000

• SBI, 7%, 10 years: ₹581/month
• Bank of Baroda, 8.4%, 10 years: ₹618/month
• Canara Bank, 9.25%, 7 years: ₹799/month

For a household with a ₹2,500 electricity bill, a 2 kW system saves approximately ₹1,800–₹2,000/month. Net of EMI (₹581), the customer saves ₹1,219–₹1,419/month from day one. After the EMI ends in 10 years, the full ₹2,000 saving falls to the bottom line every month for the remaining 15 years of the panel's rated life.

3 kW System, The Sweet Spot for ₹3,000+ Bills

Total cost: ₹1,65,000 | Subsidy: ₹78,000 | Net principal: ₹87,000

• SBI, 7%, 10 years: ₹1,010/month
• Bank of Baroda, 8.4%, 10 years: ₹1,075/month
• Tata Capital, 11%, 5 years: ₹1,890/month

For a customer paying ₹3,500/month on electricity, the 3 kW system at SBI rates costs ₹1,010/month in EMI while eliminating approximately ₹2,800 of their electricity bill. Net saving: ₹1,790/month from month one, even while paying the loan.

The A/B Test: Proposal With vs Without EMI Section

The most persuasive argument for adding an EMI section is what happens when you remove it. An EPC in Pune running QuickEstimate tracked two proposal variants over a six-month period in 2025:

Variant A (control): Proposal showed gross cost, subsidy deduction, and net cost. No EMI information.

Variant B (EMI section added): Same data as Variant A, plus a three-row EMI table showing SBI, Bank of Baroda, and Tata Capital monthly instalments for the recommended system size.

The EMI section alone doubled the conversion rate and cut the "price too high" objection rate by more than half. It also shortened the sales cycle by six days. For an EPC doing 20 proposals a month, that is 10 additional deals per month from a single proposal change.

Pros and Cons of Including EMI in Every Proposal

What to Say When Presenting the EMI Section

The EMI table is only as effective as the conversation around it. Here is the script that top-converting installers use:

"So the total installed cost for your 3 kW system is ₹1.65 lakh. But after the PM Surya Ghar government subsidy of ₹78,000, which goes straight to your bank loan, your actual loan is ₹87,000. At SBI's rate, that works out to ₹1,010 per month for ten years. Your current electricity bill is ₹3,500. After the system is installed, your bill drops to roughly ₹700 on your worst month. So you're paying ₹1,010 EMI, saving ₹2,800 on your bill, you're ahead by ₹1,790 every single month while you're still paying the loan. After ten years, the loan ends. The panels have a 25-year life. So the next fifteen years, you save ₹2,800+ per month with zero EMI."

This script takes 45 seconds. It is not a pitch, it is a maths lesson that happens to close a deal. See how this fits into the wider sales conversation at how to pitch PM Surya Ghar to customers and the solar sales funnel India guide.

How QuickEstimate Auto-Generates EMI Tables in Proposals

Building an EMI table from scratch every time you create a proposal takes 15–20 minutes. It requires the correct subsidy calculation, the current bank rate, and the EMI formula, three things that a busy sales rep in the field should not have to look up manually.

• QuickEstimate's Proposal Generator auto-calculates the correct PM Surya Ghar subsidy for the entered system size using live MNRE slabs, the flat-rate error is impossible
• EMI figures for SBI, Bank of Baroda, and Tata Capital are pre-loaded with current rates and auto-calculate from the net principal in seconds
• The net monthly saving row, "Your saving minus your EMI", is computed automatically from the customer's electricity bill you enter during lead capture
• The compliance disclaimer is baked into every EMI section by default, no rep can accidentally remove it
• The complete proposal, including the EMI table, is generated as a mobile-optimised PDF that looks correct when opened on a phone, because over 74% of urban Indian consumers check documents on their phones (Statista, 2025)
• Once sent via the WhatsApp Follow-up module, the proposal is tracked, you see when it was opened, so you know when to call
• See how this fits into qualifying your leads at qualifying solar leads and your overall approach at solar sales best practices
• Book a demo or download the app to generate your first EMI proposal in under two minutes

What to Do This Week

1. Open your last five sent proposals and check whether any of them showed an EMI option. For each one that did not, calculate the EMI for SBI at 7% on the net-of-subsidy principal and note how much lower it is than the customer's electricity bill.

2. Add a three-row EMI table to your standard proposal template this week. If you are building proposals manually, this takes 20 minutes once. If you are on QuickEstimate, it is already there, turn on the EMI section in your proposal settings.

3. Add the compliance disclaimer line below the EMI table before sending any proposal with financing information. Screenshot it in your team WhatsApp group so everyone uses the same language.

Frequently Asked Questions

Should I show EMI even if the customer said they want to pay cash?

Yes. Showing the EMI option does not obligate the customer to take a loan, it simply presents an alternative. Many customers who initially say "I'll pay cash" switch to financing once they see how low the monthly EMI is relative to their savings. The EMI section reframes the price discussion and almost always works in your favour.

What if the customer's CIBIL score is below 700?

Include Tata Capital or another NBFC in your proposal alongside the bank options. NBFCs typically approve at lower CIBIL thresholds (600+) but at higher rates (11–14%). Show the NBFC EMI alongside the bank EMI and note the difference. The customer then understands what the credit score costs them monthly, and some will choose to improve their CIBIL before applying.

How often should I update the EMI rates in my proposal template?

Update at minimum once per quarter, when RBI publishes MCLR revisions that affect public-sector bank rates. SBI and BoB rates are MCLR-linked and can shift by 25–50 bps. Using a rate that is six months old in your proposal is a trust risk if the customer independently checks and finds the real rate.

Is it legal to show EMI options in a solar proposal in India?

Yes, with the standard disclaimer that EMI figures are indicative and subject to bank credit assessment. You are not acting as a lending agent, you are sharing publicly available information about partner bank products. If you are a DSA (Direct Selling Agent) for a specific bank, follow that bank's compliance guidelines on how to present their products.

What is the best system size to lead with when showing EMI?

Lead with the size the customer actually needs based on their electricity bill and roof orientation. Do not size down to make the EMI look lower, that is a short-term sales tactic that creates a long-term complaint when the customer finds the system undersized. See the solar sales funnel for how site assessment feeds into correct sizing.

How do I handle it if the bank rejects the customer after I showed them EMI figures?

This is exactly why the disclaimer exists. If you have included the standard disclaimer language, "subject to bank credit assessment, vendor does not guarantee approval", you have no legal liability. Handle it as a customer service issue: help them explore alternatives (joint loan, NBFC, state scheme) and do not abandon the lead. Most customers who want solar but cannot get a standard bank loan can still access financing through an NBFC or a state-specific scheme.

Can I show EMI for commercial solar installations?

Yes, but the loan products differ. Commercial installations typically use MSME loans, equipment finance, or lease structures rather than the PM Surya Ghar residential loan. The accelerated depreciation benefit under Section 32 also changes the economics significantly for commercial buyers, the payback period shortens even at higher commercial loan rates. A separate EMI/ROI section for commercial proposals is worth building once you start doing commercial work at volume.

How does the PM Surya Ghar subsidy affect the EMI I show?

The subsidy reduces the net loan principal, which directly reduces the EMI. A ₹78,000 subsidy on a ₹1.65 lakh system reduces the principal from ₹1.65 lakh to ₹87,000, that is a 47% reduction in the loan amount, which flows through proportionally to the EMI. Always show the gross cost, then subtract the subsidy, then show the EMI on the net figure, not on the gross. Showing EMI on the gross cost is both inaccurate and misleading.
