Solar Sales Script for Commercial Customers in India (2026)

Selling solar to a factory owner in Surat or a hospital trust in Pune is a completely different conversation from selling to a homeowner. The person across the table is not spending their own money emotionally. They are spending company money analytically, and they will forward your proposal to a CFO (Chief Financial Officer) or a CA (Chartered Accountant) before saying yes.

Most Indian EPC (Engineering, Procurement and Construction) teams lose commercial deals not on price but on conversation structure. The rep talks about panels and watts. The customer is thinking about payback, tax, and production downtime. This post gives you a full solar sales script commercial teams can read aloud, from the first discovery call to the final follow-up.

If you also sell to homes, pair this with our residential solar sales script. The two scripts share DNA but differ in who decides, how fast, and on what math.

Why commercial solar sales needs a different script

Commercial buyers decide with a spreadsheet, not with emotion. A homeowner asks "how much will I save?" A factory owner asks "what is the payback, what is the tax treatment, and who else in my industry has done this?"

The numbers explain why. Industrial and commercial tariffs in India commonly run ₹8 to ₹12 per unit, among the highest in the world relative to income levels, according to Mercom India, 2025. Rooftop solar generation costs roughly ₹2.5 to ₹3.5 per unit over system life. That gap is your entire pitch.

One more difference: the decision unit. In residential, one person says yes. In commercial, you sell to the owner, the plant head, the accounts team, and sometimes a board. Your script must arm your champion inside the company to resell for you.

Residential vs commercial, how the conversation changes

The same rep cannot use the same script for both. The table below maps the differences your sales team must internalise before their first commercial meeting.

Notice the subsidy row. There is no PM Surya Ghar central financial assistance for commercial and industrial consumers under the PM Surya Ghar National Portal guidelines, 2024. If your rep opens a factory pitch with subsidy talk, the owner's CA will correct them in the first meeting, and your credibility is gone.

The CFO-First Script, our framework for commercial meetings

The CFO-First Script is a simple rule: every commercial solar conversation must survive being repeated to the CFO by someone else. Your contact will forward your numbers. So every claim you make must be written down, sourced, and reproducible on a calculator.

The framework has four parts, one per meeting stage:

1. 1

   Discovery call, find the bill

   Get the monthly bill amount, tariff per unit, sanctioned load, and the name of whoever signs capital expenditure. No bill, no site visit.

2. 2

   Site visit, confirm the load story

   Walk the roof, check shadow and structure, confirm the daytime load profile, and collect 12 months of bills physically or on WhatsApp.

3. 3

   Proposal walkthrough, lead with payback

   Present savings per year first, payback second, system specs third. The spec sheet is appendix material for the plant head, not the opener.

4. 4

   Objection and follow-up, arm the champion

   Handle payback, depreciation, and GST questions in writing, then follow up on a fixed cadence so the deal never goes cold silently.

The discovery call script

Goal of this call: confirm the bill, the tariff, and the decision process, in under 10 minutes. Do not pitch panels. Read this aloud and adapt the names.

"Namaste [Name] ji, this is [Rep] from [EPC name]. We work with factories and commercial buildings in [city] to cut their electricity bill with rooftop solar. I will keep this short, two minutes of questions, and then I can tell you honestly whether solar makes sense for your unit. First, roughly what is your average monthly electricity bill? And what tariff are you paying per unit, if you know it?"

(Listen. Note the numbers.)

"Thank you. One more: is your connection HT (High Tension) or LT (Low Tension), and what is your sanctioned load in kVA? ... Perfect. Last question, if the numbers work out, who else besides you would review this, your CA or a partner? I ask because I prepare the proposal so it is easy to forward to them."

Three things happened here. You got the bill. You got the load. And you found out who the real decision unit is, without insulting your contact. According to QuickEstimate platform data, 2026, commercial deals where the rep identified the finance reviewer in call 1 close about 30% faster.

If the bill is under roughly ₹40,000-50,000 per month, the project may be too small for a commercial pitch. Our guide on commercial solar system sizing shows the minimum viable sizes.

The site-visit script

The site visit is not a survey with small talk attached. It is the second sales meeting. Your job: confirm the load story the bills told you, and make the customer picture the plant on their roof.

"Before we go up to the roof, can I see your main meter and the last 12 months of bills? I want to check two things: your daytime consumption pattern and whether your demand charges are a big part of the bill."

(On the roof.)

"This shadow from the water tank, we will design around it or suggest moving it. Your roof is roughly [X] square feet, which comfortably fits [Y] kW. Based on your bills, that covers about [Z]% of your daytime load. Your factory runs mostly 9 to 6, correct? That is ideal, because solar generates exactly when you consume."

Two commercial-specific points belong in this conversation. First, demand charges: many HT bills include a fixed charge on sanctioned or contract demand, and solar reduces energy charges more than demand charges, so savings estimates must use the energy component of the bill. Second, net metering caps: most states cap commercial net metering eligibility, often at 1 MW or at the sanctioned load, and rules differ between MSEDCL, DGVCL, and TANGEDCO. Our explainer on the net metering cap rules and the net metering glossary entry cover the basics; always confirm the current regulation with your DISCOM before promising export credit.

The proposal walkthrough script, with ROI math

Present the proposal in person or on a video call, never just on WhatsApp with "please see attached". Open with the savings line.

"I will start with the conclusion, then show the math. This 100 kW plant saves you roughly ₹10 to ₹11 lakh per year at your current MSEDCL tariff, and pays for itself in about 4 years. After that, the electricity is effectively free for 20-plus years. Now let me show you how we got these numbers."

Here is the sample math block behind that statement. This is a clearly labelled hypothetical example, not a customer case study.

Hypothetical example, 100 kW rooftop, Gujarat factory, DGVCL HT tariff:

• System size: 100 kW, project cost ₹38 lakh (₹38 per W, typical EPC pricing for commercial rooftop, Mercom India, 2025)
• Annual generation: 1,50,000 units (1,500 kWh per kWp per year, Gujarat irradiance)
• Blended tariff offset: ₹8.50 per unit (energy charges on the HT bill)
• Annual savings: 1,50,000 x ₹8.50 = ₹12,75,000, minus O&M and insurance of about ₹1.5 lakh, net savings about ₹11.2 lakh per year
• Simple payback: ₹38 lakh / ₹11.2 lakh = about 3.4 years, before tax benefits
• With 40% accelerated depreciation benefit, effective payback often drops below 3 years for a profitable company in the 25-30% tax bracket. Confirm the exact benefit with the customer's CA.

For the full walkthrough of this calculation, including sensitivity tables, send your reps to our commercial solar ROI calculation guide. The solar sales pitch guide for India covers the meeting psychology behind this ordering.

The CFO objection script, payback, depreciation, and GST

These three objections come up in nearly every commercial deal. Answer them in the CFO's vocabulary, and always tell the customer to confirm rates with their CA.

Objection 1: "Four years payback is too long."

"Fair. Let me put it differently. At ₹8.50 per unit, this plant returns about 29% per year on the capital, tax-free at the operating level, for 25 years. Which fixed deposit or machine in your factory gives you that? The payback framing hides the point that after year 4, your cost per unit drops from ₹8.50 to under ₹1."

Objection 2: "What about depreciation?"

"Solar plant and machinery qualifies for accelerated depreciation at 40% on written down value under the Income Tax Act. For a company in the 25-30% bracket, the year-1 tax saving on a ₹38 lakh plant is roughly ₹3.8 to ₹4.5 lakh, which shortens the effective payback meaningfully. Please confirm the exact rate and treatment with your CA, we are solar engineers, not tax advisors, and rates do change."

Objection 3: "How does GST work on this?"

"Solar EPC contracts are generally taxed at 12% GST under the composite supply valuation, and as a business you can usually claim input tax credit on it, which further reduces your net cost. The exact treatment depends on your registration and contract structure, so please verify with your CA before signing."

Our deeper post on accelerated depreciation for solar gives your reps the full mechanics to leave behind as a one-pager.

Should you lead with ROI or with energy security?

Both hooks work in Indian commercial sales, but on different buyers. Match the opener to the customer's pain.

Default to ROI for factories and warehouses. Add the energy-security angle only when the customer mentions outages, diesel costs, or critical loads, and be honest that backup requires hybrid or storage design.

The follow-up script

Commercial deals die of silence, not rejection. According to JMK Research, 2025, commercial rooftop projects typically involve 3 to 5 stakeholder touchpoints before a purchase order. Use this cadence after the proposal walkthrough.

Day 3, the nudge (WhatsApp):

"Namaste [Name] ji, checking if you had a chance to review the proposal with your CA. The two numbers most CAs ask about are the tariff assumption (₹8.50 per unit from your March bill) and the depreciation rate. Happy to walk your CA through the math on a 10-minute call."

Day 7, the proof (WhatsApp or call):

"Sharing photos and the generation report from a 120 kW plant we commissioned for a [similar industry] unit in [nearby city] last year. Their first-year savings came within 5% of our estimate. Would a site visit to see it running help your decision?"

Day 14, the last-call (call, then WhatsApp):

"[Name] ji, I do not want to keep disturbing you. Three honest options: we move ahead, you tell me the concern holding this back, or I close the file for now and check back next quarter. Which one works? Current pricing holds until [date], module rates have been moving up this quarter."

The Day 14 message works because it gives permission to say no. In QuickEstimate platform data, 2026, deals that received a direct close-or-defer message re-engaged at roughly twice the rate of deals left on "just checking in" messages.

How QuickEstimate fits

The CFO-First Script only works if your numbers are fast, consistent, and forwardable. That is the part most EPC teams break: the rep does mental math on a calculator, the owner approves a different number, and the PDF that reaches the CFO has a third. QuickEstimate keeps one number across the whole chain, from site visit to WhatsApp delivery, and your pricing plans stay flat whether you send 10 or 100 commercial proposals a month.

• Proposal Generator, 60-second branded PDF with payback and savings math pre-computed, ready to forward to the customer's CA.
• WhatsApp Follow-up, send the proposal in the customer's chat and get reminders on the Day 3, Day 7, Day 14 cadence.
• Pipeline Management, see which commercial deals are stuck at Proposal Sent and which rep is sleeping on follow-ups.
• Sales Reports, track commercial close rate and average days-per-stage across your team.

What to do this week

1. Pull one live commercial lead and run the discovery script verbatim. Get the monthly bill, tariff, sanctioned load, and the finance reviewer's name. If they refuse to share a bill, disqualify politely and move on.
2. Build your one-page CFO objection sheet. Copy the payback, depreciation, and GST answers from this post, add your actual EPC pricing, and get your own CA to review the tax lines before your reps use them.
3. Set the Day 3, Day 7, Day 14 cadence for every open commercial deal. Put each follow-up as a dated task, not a mental note. If your team tracks this in QuickEstimate, the reminders fire automatically on WhatsApp.

Frequently asked questions

What is a good payback period to quote for commercial solar in India?

Quote 3 to 5 years as the honest band for commercial rooftop in India, according to Mercom India, 2025. The exact number depends on the customer's DISCOM tariff, daytime load share, and project cost per watt. A factory paying ₹9 per unit with 80% daytime consumption lands near 3 years. A unit at ₹6.50 per unit with heavy night load lands near 5. Always compute payback from the customer's own bills, and show the math so their CA can verify it line by line.

Is there any government subsidy for commercial rooftop solar?

No. The PM Surya Ghar Muft Bijli Yojana central financial assistance applies to residential households only, per MNRE guidelines, 2024. Commercial and industrial consumers get no central capital subsidy for rooftop solar. What they do get is accelerated depreciation at 40% written down value and GST input tax credit, both of which reduce effective project cost for a tax-paying business. Sell those benefits instead, and never open a commercial pitch with subsidy talk.

How do I handle the CFO's objection that payback is too long?

Reframe payback as an annual return. A 4-year payback equals roughly 25% annual return on capital, sustained for 25 years with very low risk, because sunlight is free and tariffs generally rise. Compare it to fixed deposits or other capital uses inside the business. Then layer the tax benefits, 40% accelerated depreciation and GST input tax credit, which can pull effective payback under 3 years for a company in the 25-30% tax bracket. Close by telling them to verify the tax treatment with their CA.

What documents should I collect at a commercial site visit?

Collect 12 months of electricity bills, the sanctioned or contract load in kVA, the connection type (HT or LT), and roof details: usable area, shadow sources, structure type and age, and roof ownership or lease terms. Also note the daytime load pattern and whether they run diesel generators. These inputs decide system size, savings math, and net metering eligibility. Walking in without the bills means you will do the site visit twice.

Should I quote a price per kW on the first commercial call?

No. Commercial pricing depends on roof structure, sanctioned load, cabling distance, and DISCOM liaisoning scope, none of which you know on call 1. A verbal ₹ per kW quoted early becomes the anchor your written proposal is judged against, and you will either overquote and lose the deal or underquote and lose your margin. Say you will give one correct number after seeing one bill and the roof, then deliver it within 48 hours.

How big can a commercial net-metered system be in India?

Most states cap net metering for commercial consumers at 1 MW or at the sanctioned load, whichever is lower, and several states have tighter caps or gross-metering rules above certain sizes. Rules differ between DISCOMs like MSEDCL, DGVCL, and TANGEDCO, and they change through state regulator orders. Check the current regulation with your DISCOM or state electricity regulatory commission before promising export credit, and size the system against daytime consumption first.

How long does a commercial solar deal take to close?

Plan for 60 to 90 days from first call to purchase order, based on QuickEstimate platform data, 2026. The cycle stretches because multiple stakeholders review the proposal: owner, plant head, CFO or CA, and sometimes a board. Deals close faster when you identify the finance reviewer in the first call, deliver the proposal within 48 hours of the site visit, and follow a fixed Day 3, Day 7, Day 14 cadence instead of ad-hoc check-ins.
