How to Start a Solar EPC Business in India

Take an illustrative example: a made-up installer we will call Rohit (a composite, not a real person), who did not plan to become a solar EPC (Engineering, Procurement, and Construction) owner. It is worth pinning down what solar EPC actually means before diving into the how. Say he is a site supervisor at a large EPC firm in Surat earning ₹22,000 a month, watching his employer bill ₹1.8 lakh on a 3 kW residential job he has managed entirely. "Agar main khud karta toh ₹40,000 net ho jaata," he tells a friend. Two months later, he registers a proprietorship.

India's solar installers range from one-man operations to large firms. The PM Surya Ghar Muft Bijli Yojana aims at 1 crore households, and 51.58 lakh were benefiting as of 12 August 2026 (PIB, 13 August 2026), so demand is not the usual problem. A weak foundation is, echoing the common mistakes EPC companies make in rooftop solar.

This guide covers every step of that foundation: legal structure, registrations, equipment procurement, team building, tool stack, and landing your first five paying clients. When you are ready to write it all down, the solar business plan template for a new installer turns these steps into fill-in tables.

The Solar EPC Business Launch Checklist, 6 phases

This is the master framework. Each section below covers one phase in full. Use this as your operating checklist, not just a reading list.

1. P1

   Legal, Register your business entity

   Choose between Sole Proprietorship, LLP, or Private Limited Company. Register for GST. Get a PAN for the business.

2. P2

   Empanelment, Register with MNRE and your state DISCOM

   PM Surya Ghar vendor registration on the national portal. DISCOM empanelment for your service area.

3. P3

   Equipment, Set up your panel, inverter, and BoS supply chain

   Identify 2–3 distributors, understand DCR compliance, and negotiate payment terms before you get your first order.

4. P4

   Team, Hire your first sales rep and electrician

   A small team can handle a handful of installations a month (our illustrative estimate: 8 to 10). More team without a system is chaos.

5. P5

   Tools, Build your digital operating system

   Proposal generation, a lead CRM, and WhatsApp follow-up. A consistent system helps a small team look and work professionally.

6. P6

   First client, Your marketing and outreach plan

   Word of mouth, housing society targeting, and IndiaMART. Your first 5 clients define your reputation and referral network.

Phase 1, Legal entity: Proprietorship vs LLP vs Pvt Ltd

The legal structure you choose affects your tax liability, fundraising ability, and credibility with large commercial clients. The setup costs below are illustrative ranges for planning, so get quotes from your CA. Here is how to decide:

Recommendation for most new EPCs: Start as a Sole Proprietorship or LLP to keep compliance low. If you plan to bid for commercial or government tenders above ₹50 lakh, move to Pvt Ltd within 18 months. Some lenders and large commercial clients may prefer a registered company.

GST registration is mandatory above the turnover threshold under the CBIC GST framework. The 32nd GST Council thresholds (PIB, effective 1 April 2019) are ₹40 lakh for goods (₹20 lakh at a State's option) and ₹20 lakh for services (₹10 lakh in special category States); a solar EPC contract mixes both, so ask your CA which applies. Registering early signals legitimacy and lets you claim input tax credit on equipment purchases. GST on solar devices and systems is 5% from 22 September 2025 (down from 12%). For an EPC contract, notification 9/2025-Integrated Tax (Rate) deems 70% of the gross consideration as the goods and 30% as the service. The service portion falls under entry 38 of notification 11/2017-Central Tax (Rate), at 9% CGST (with 9% SGST) or 18% IGST on an inter-State supply (CBIC portal, checked 31 October 2026).

MSME registration (Udyam Registration under MSME Ministry) is free (the portal says zero cost, no fee) and takes about half an hour on udyamregistration.gov.in. A Udyam certificate helps when you apply for MSE credit, and the CGTMSE guarantee ceiling is ₹10 crore from 1 April 2025 (PIB, 23 July 2026). Do this in Phase 1, there's no reason to delay.

Phase 2, Empanelment: MNRE and DISCOM registration

To take PM Surya Ghar subsidy jobs, you need to be a registered vendor on the national portal, where customers pick a vendor when they apply. You can still sell solar outside the scheme, but the subsidy is the main reason many residential customers buy.

Step 1: PM Surya Ghar vendor registration

Register on the PM Surya Ghar National Portal as a vendor. The portal and your DISCOM list the exact documents, so confirm there. Typical items:

• GST registration certificate
• Business PAN
• Bank account details
• Authorised signatory ID and PAN

We did not find a registration fee or an approval time in the MNRE manuals, so check the portal rather than relying on a fixed number of days.

Step 2: DISCOM empanelment

Each DISCOM in your service territory may have its own empanelment process for net metering installers. For Gujarat, this means DGVCL (Dakshin Gujarat Vij Company Limited), MGVCL, PGVCL, or UGVCL depending on your district, and if you're weighing where to launch, it's worth studying the solar installer business landscape in Gujarat specifically. For Maharashtra, MSEDCL. For Delhi, BSES Rajdhani, BSES Yamuna, or Tata Power DDL.

Read your DISCOM's list. The categories to expect are an electrical contracting licence, proof of a technically qualified team member, and possibly insurance and past-work references, but the specifics (including how many references) differ by DISCOM and we have not verified them for each:

Electrical contracting license: Most states need a licensed electrical contractor to sign off on installations. If you don't have this yourself, hire an electrician with the supervisor licence your state board requires. Many experienced solar electricians have this, it is a key hiring criterion (Phase 4).

For detailed PM Surya Ghar registration steps, see PM Surya Ghar vendor registration and what is PM Surya Ghar Yojana.

Phase 3, Equipment: panels, inverters, and BoS supply chain

Your equipment choices determine your installation quality, warranty claim exposure, and gross margin, and mapping them against the full solar engineering workflow Indian EPCs follow helps you see where procurement decisions ripple downstream. Get this wrong and you're doing rework and refund conversations instead of new sales.

DCR (Domestic Content Requirement) compliance

For PM Surya Ghar Muft Bijli Yojana-eligible installations, panels must be DCR-compliant (manufactured in India), which means meeting the DCR compliance requirements MNRE has set for domestic content. According to MNRE guidelines, non-DCR panels do not qualify for central subsidy disbursement. Check the MNRE Approved Model and Manufacturer List (ALMM) before purchasing, and get familiar with the ALMM listing process so you know exactly which models qualify. The list changes from time to time, so verify before every batch purchase, ideally against a resource like the ALMM List Phase III requirements.

Distributor vs direct manufacturer

As a rule of thumb (ours), at low monthly volumes buy from a distributor, who handles logistics and after-sales support. Ask for credit terms in writing; there is no standard to count on. At much higher volumes, approach manufacturers directly for better pricing. The price ranges in the table above are illustrative planning figures, not quotes.

Build relationships with at least two distributors for panels and two for inverters. Single-source dependency is dangerous in a market where supply can be disrupted during festival season or when a brand releases a popular new model.

Phase 4, Team: hiring your first two people

A solo EPC owner doing both sales and installation will hit a ceiling quickly. As an illustration, a first team is one sales rep and one experienced electrician/installer. The pay figures below are illustrative, so check your local market.

Hiring your first sales rep (often called "sales boy" in the industry)

What to look for:

• 1–2 years of direct sales experience (insurance, solar, or any door-to-door field sales)
• Smartphone comfortable (they'll use CRM and proposal apps daily)
• Speaks the local language fluently
• Willingness to do site visits on commission

Compensation structure for a first sales hire:

• Base: ₹12,000–15,000/month
• Commission: ₹1,500–2,500 per closed residential installation
• Target: 6–8 installations per month = ₹21,000–35,000 total

Don't offer a high base to save on commission, a high base with low commission creates a salary-collector, not a closer. The commission must feel meaningful.

Hiring your first electrician/installer

Must-haves:

• The electrical supervisor licence your state board requires
• Experience with rooftop solar installation (even 5 completed jobs is enough)
• Comfort with working at height

Compensation (illustrative): ₹18,000–25,000/month base, or ₹2,500–4,000 per installation on contract.

Phase 5, Tools: your digital operating system

This is where most new EPCs underinvest, and where the best ones pull ahead. Your digital tools are not software expenses, they are the system that lets your team operate above their experience level. For the full tool list by stage of your business, see the complete Indian solar installer stack.

The three tools you need from Day 1:

Tool 1: Solar proposal generator

The most visible signal of professionalism to a customer is the quality of your proposal. A customer comparing your Excel printout to a competitor's branded PDF with the subsidy and your company logo may choose the professional-looking one even if your price is slightly higher.

Quickest Solar CRM lets a sales rep make an estimate on the mobile app (Android, iOS or web), using the price list with margin that the admin sets, and build a proposal from your template (logo, items, product photos, terms and conditions) with the PM Surya Ghar subsidy applied. The rep can then share the PDF on WhatsApp.

Tool 2: Lead CRM

Without a CRM, leads fall through cracks. Your sales boy takes down names in a notebook, visits happen, proposals get sent, and then nobody follows up systematically. At ₹1.5–2 lakh per installation, letting one lead go cold can cost you an installation's margin.

A CRM shows Rohit, through lead stages, logged activities, filters and follow-up reminders, which leads sit at which stage and which need a call today, and the dashboard shows the pipeline. This is not a "big company" need, this is a 10-installation-a-month EPC need.

Tool 3: WhatsApp follow-up

In India, a lot of customer conversation happens on WhatsApp, including objections. Your proposal follow-up should be on WhatsApp, not email or a phone call alone.

The 5-Touch Close framework depends on consistent follow-up messages. Without a reminder system, Touch 3 gets dropped and Touch 4 never happens. For a full strategy guide, see WhatsApp solar sales strategy and solar lead via WhatsApp conversion.

For pricing strategy on proposals, also see solar business pricing strategy.

Phase 6, First 5 clients: where they actually come from

New EPCs waste thousands on Google ads before they've landed their first five clients. The best first clients come from three channels that cost almost nothing.

Channel 1: Housing society targeting

One housing society puts many households in one place. Approach the society secretary with an offer: "Free solar feasibility assessment for the entire society, I'll present the results in a 30-minute evening meeting." If the secretary goes solar, neighbours can see a working system, which makes the next conversation easier.

Channel 2: Network (friends, relatives, ex-colleagues)

Your first installation should be for someone you know. Quote them a fair price and ask, with their written consent, to use before/after DISCOM bill photos, a photo of the installation, and their case in pitches. Do not make a discount conditional on a positive review. This case study becomes your Act 3 proof for the next 50 pitches.

Channel 3: IndiaMART listing

A well-optimised IndiaMART listing can bring inbound enquiries. Fill the listing with specifics: system sizes, DISCOM coverage areas, and your PM Surya Ghar vendor status. Fast callbacks win leads; slow ones lose them.

Your pricing strategy in Year 1

New EPCs make two common mistakes: pricing too low to win business (and discovering it doesn't cover costs) or pricing identical to established EPCs (and losing to their reputation and scale).

The right Year 1 strategy: price at par with mid-market competitors on material costs, but compete on speed and service. Offer:

• Proposal within 2 hours of site visit
• DISCOM application filing within 48 hours of sign-off
• Installation within 10 working days of token advance

These three speed commitments are things busy established EPCs may not match. A new EPC's advantage is hunger and speed.

For a complete pricing framework, see solar business pricing strategy, covering the four pricing models Indian EPCs use and when to use each. When you are ready to quote megawatt-scale ground-mount work, read our 1 MW solar power plant cost guide first.

How Quickest Solar CRM fits your EPC launch

Get your proposal and follow-up system in place before you hire your second sales rep. The tool stack creates the standard that new reps slot into, rather than each rep inventing their own process.

• Proposal Generator, Your sales rep builds a branded PDF proposal from your template on the mobile app, with the PM Surya Ghar subsidy applied and your admin-set price list behind it. No design skills needed.
• Lead Management, Add every enquiry as a lead, or bulk import from Excel. Rohit uses filters, labels and follow-up reminders to see which leads need a call today, and the dashboard shows this month's pipeline.
• Pipeline Management, Move leads through stages (New → Visited → Proposal → Token Paid → Installing → Commissioned), with customisable stages, and see where each lead stands on the dashboard.
• WhatsApp Follow-up, Share the proposal PDF on WhatsApp and set follow-up reminders for each touch of the 5-Touch Close. Saved message templates keep the messages consistent.

Quickest Solar CRM's free plan covers 1 user and 10 proposals a month, with no card. The Pro plan is ₹6,999 per user per year with a 3-user minimum (₹20,997 for 3 users), billed yearly with a GST invoice. Start at quickestimate.co.

You'll also want to use the solar sales pitch India script for training, the solar customer objections guide for rep training, and the close a solar deal sequence for your follow-up system.

What to do this week

1. 1

   Complete Phase 1 and 2 this week if you haven't already

   GST registration (once you cross the threshold), MSME Udyam registration (free), and PM Surya Ghar portal vendor registration. Together they set up the base for taking subsidy jobs.

2. 2

   Identify 3 housing societies to approach next week

   Look for societies with 50–200 flats within 15 km of your base. Find the secretary's name via Google or local Facebook groups. Prepare a one-page "Free Solar Feasibility Assessment" offer, that is your door-opener, not a sales pitch.

3. 3

   Set up Quickest Solar CRM before your first sales rep starts

   Create your account at quickestimate.co, upload your company logo and default pricing, and test-generate one proposal. Then on Day 1 of your sales rep's onboarding, the first thing they learn is the proposal tool, not a notebook.

Frequently asked questions

What is an EPC company in solar and what do they do?

An EPC (Engineering, Procurement, and Construction) company in solar handles the complete project lifecycle: system design (engineering), sourcing panels, inverters, and balance of system (procurement), and physically installing and commissioning the system (construction). In residential rooftop solar, EPC companies also process PM Surya Ghar subsidy applications and coordinate DISCOM net metering connections on behalf of customers.

How much capital do I need to start a solar EPC business in India?

Our planning estimate for a lean residential EPC start is ₹5 to ₹15 lakh, and it is worth reading a full breakdown of how much capital a new solar business really needs before you commit funds. The figures are illustrative, not official. They cover registration and licensing, basic tools and safety equipment, a small team for the first months, and working capital for the first few installations. Do not invest in inventory before you have orders.

Is MNRE empanelment mandatory for solar EPC businesses?

Not to sell solar in general, but you need to be a registered vendor on the national portal to take PM Surya Ghar subsidy jobs. The subsidy goes to the customer: ₹30,000 per kW for the first 2 kW and ₹18,000 for the third kW, capped at ₹78,000 (MNRE guidelines, July 2025). Register at pmsuryaghar.gov.in before you start selling subsidy-backed systems.

What is the profit margin on a residential solar installation in India?

There is no official figure, and it depends on your costs and whether you own or hire installation labour. As an illustration, a 3 kW installation at ₹1.85 lakh with ₹1.25 lakh in equipment and labour costs leaves ₹60,000 gross (about 32%) before overhead; your own quotes will differ. Our solar business margins in India post covers the range in more detail.

What is DCR compliance in Indian solar and why does it matter?

DCR (Domestic Content Requirement) means the solar panels must be manufactured in India. MNRE requires DCR-compliant panels for PM Surya Ghar subsidy eligibility. The list of approved manufacturers is maintained in the ALMM (Approved Models and Manufacturers List) on the MNRE website. Using non-DCR panels means your customers cannot claim the central subsidy, which effectively kills your competitive position on residential projects.

How many installations per month can a 2-person EPC do?

With one sales rep doing 2–3 site visits per day and one electrician/installer handling installations, a 2-person EPC might plausibly complete 8–12 residential installations per month (our estimate, not a benchmark). The limiting factor is usually the installation team rather than the sales side, so add a second installation team before adding more sales reps.

What software tools do new solar EPCs need?

Three tools from Day 1: (1) A proposal generator that builds a branded PDF with the PM Surya Ghar subsidy applied. (2) A lead CRM to track every enquiry and follow-up across your team. (3) A way to share proposals on WhatsApp and remind yourself to follow up. Quickest Solar CRM covers all three, with a free plan of 1 user and 10 proposals a month.
