How to Start a Solar EPC Business in India

Rohit didn't plan to become a solar EPC (Engineering, Procurement, and Construction) owner. He was a site supervisor at a large EPC firm in Surat in 2019, earning ₹22,000 a month, watching his employer bill ₹1.8 lakh on a 3 kW residential job he'd managed entirely. "Agar main khud karta toh ₹40,000 net ho jaata," he told a friend. Two months later, he registered a proprietorship. Six months after that, he had three paid installations done.

Today there are an estimated 80,000+ solar EPC companies and installers registered across India, according to MNRE, ranging from one-man operations to 400-person firms. The PM Surya Ghar Muft Bijli Yojana target of 1 crore residential installations by 2027 means the market is enormous and actively growing. But 60% of small EPCs fail within 3 years, not because the demand isn't there, but because they get the foundation wrong.

This guide covers every step of that foundation: legal structure, registrations, equipment procurement, team building, tool stack, and landing your first five paying clients.

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

   Two people can handle 8–10 installations per month. More team without a system is chaos.

5. P5

   Tools, Build your digital operating system

   Proposal generation, lead CRM, and WhatsApp follow-up. This is what separates professional EPCs from unprofessional ones.

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. 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. Lenders and large commercial clients often require a registered company.

GST registration is mandatory once your annual turnover exceeds ₹20 lakh (₹10 lakh in special category states) under the CBIC GST framework. But register early even if you're below threshold, GST registration signals legitimacy to customers and allows you to claim input tax credits on equipment purchases. GST on solar panels is 5% (reduced from 12% in 2021).

MSME registration (Udyam Registration under MSME Ministry) is free, takes 10 minutes on udyamregistration.gov.in, and gives you access to priority sector lending, CGTMSE guarantees, and government procurement preferences. Do this in Phase 1, there's no reason to delay.

Phase 2, Empanelment: MNRE and DISCOM registration

Without empanelment, you cannot process PM Surya Ghar subsidies for your customers. This is not optional, it is the legal requirement to operate as a residential solar EPC in India after 2024.

Step 1: PM Surya Ghar vendor registration

Register on the PM Surya Ghar National Portal as a vendor. Required documents:

• GST registration certificate
• Business PAN
• One completed solar installation certificate (some states require proof of 1 prior installation)
• Bank account details
• Authorised signatory Aadhaar and PAN

The registration is free. Approval takes 7–15 working days after document verification. Once approved, you get a Vendor ID that you need for every subsidy application you file on behalf of customers.

Step 2: DISCOM empanelment

Each DISCOM in your service territory has 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. For Maharashtra, MSEDCL. For Delhi, BSES Rajdhani, BSES Yamuna, or Tata Power DDL.

Empanelment typically requires:

• Electrical contracting license (Class C or equivalent, from your state's Electrical Inspectorate)
• Liability insurance certificate
• 2–5 completed installation references
• Technical qualification proof of at least one team member

Electrical contracting license: In most states, you need a licensed electrical contractor to sign off on installations. If you don't have this yourself, hire an electrician with a valid Class C supervisor license. 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. 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). 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. Updated quarterly, verify before every batch purchase.

Distributor vs direct manufacturer

For volumes below 50 kW per month, buy from a distributor, they give credit terms (30–45 days net), handle logistics, and provide after-sales support. For volumes above 100 kW/month, approach manufacturers directly for better pricing and priority supply during module shortages.

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 caps at 5–6 installations per month. To reach ₹30–40 lakh monthly revenue, you need a minimum two-person team: one sales rep and one experienced electrician/installer.

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:

• Class C electrical supervisor license (state Electrical Inspectorate)
• Experience with rooftop solar installation (even 5 completed jobs is enough)
• Comfort with working at height

Compensation: ₹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.

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 subsidy calculations, EMI breakdown, and your company logo, they'll choose the professional-looking one even if your price is slightly higher.

QuickEstimate's proposal generator lets any sales rep generate a PM Surya Ghar-compliant proposal in 60 seconds from their Android phone. No laptop. No WiFi. No waiting for the office. The rep fills in four fields, customer name, system size, roof address, and electricity bill, and gets a PDF with subsidy, net cost, EMI, and payback period pre-calculated.

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 is like dropping ₹25,000 on the floor.

A CRM shows Rohit: which leads each rep has visited this week, which ones have received proposals, which ones are 7+ days without follow-up, and what the pipeline value is by stage. This is not a "big company" need, this is a 10-installation-a-month EPC need.

Tool 3: WhatsApp integration

In India, deals close on WhatsApp. DISCOM approvals get communicated on WhatsApp. Customer objections get raised on WhatsApp. Your proposal follow-up needs to be on WhatsApp, not email, not phone call alone.

The 5-Touch Close framework depends heavily on timed WhatsApp messages. Without a system that schedules and tracks these, 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 with 100 flats is worth 40–60 qualified leads. 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, 10–15 more flats follow within 3 months (social proof is extremely powerful in Indian housing societies).

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

Your first installation should be for someone you know. Offer them a 10–15% discount in exchange for a detailed testimonial, before/after DISCOM bill photos, a photo of the installation, and permission to use their case in pitches. This case study becomes your Act 3 proof for the next 50 pitches.

Channel 3: IndiaMART listing

A well-optimised IndiaMART listing generates 5–15 inbound enquiries per month for a new EPC. Fill the product listing with specific: system sizes, DISCOM coverage areas, PM Surya Ghar empanelment status, and response time guarantee. The EPCs that win IndiaMART leads are the ones who call back within 10 minutes, most take 24 hours.

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 most established EPCs can't match because they're too busy. 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.

How QuickEstimate fits your EPC launch

The fastest-growing EPCs in India, those going from 0 to ₹50 lakh GMV within their first year, share one pattern: they get their proposal and follow-up system in place before they hire their 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 sends a PM Surya Ghar-compliant, branded PDF proposal from their phone in 60 seconds. No laptop, no design skills, no waiting for the owner to approve each quote. This is what makes a two-person EPC look like a 20-person company.
• Lead Management, Every enquiry from IndiaMART, WhatsApp, and referrals tracked in one place. Rohit sees which rep has visited, which leads need a call today, and what this month's pipeline looks like.
• Pipeline Management, Move leads through stages (New → Visited → Proposal → Token Paid → Installing → Commissioned) and see your month's revenue forecast before the month ends.
• WhatsApp Follow-up, Schedule the 5-Touch Close sequence for every lead. Know when customers open your proposals. Stop losing warm leads to silence.

QuickEstimate's free plan covers 10 proposals per month, enough for your first 3 months of growth. When you cross 10 installations per month, the Pro plan at ₹6,999/user/year pays for itself in the first closed lead of the month. 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, MSME Udyam registration (free, 10 minutes), and PM Surya Ghar portal vendor registration. These three give you the legal standing to process subsidies for customers, without them, you are just an electrician, not an EPC.

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 QuickEstimate 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?

A lean EPC startup can begin with ₹3–5 lakh in working capital. This covers: legal registration (₹10,000–25,000), basic tools and safety equipment (₹30,000–50,000), a 2-person team for the first month (₹30,000–40,000 in salaries), and working capital for the first 2–3 installations (most EPCs collect 50–60% advance from customers, which covers equipment cost). Do not invest in inventory before you have orders.

Is MNRE empanelment mandatory for solar EPC businesses?

Yes, for residential rooftop solar under PM Surya Ghar Muft Bijli Yojana. Without MNRE vendor registration, you cannot file subsidy applications for customers. The subsidy (up to ₹78,000 for a 3 kW system) is the primary reason most residential customers choose solar, without it, your conversion rate drops dramatically. Register at pmsuryaghar.gov.in before starting sales.

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

A well-run residential solar EPC earns 28–35% gross margin on materials and labour, and 18–25% net margin after overhead. On a 3 kW installation at ₹1.85 lakh, that is ₹33,000–65,000 net profit depending on your cost structure and whether you own or hire installation labour. Commercial projects (10–100 kW) typically yield 12–18% net margin but at higher absolute ticket size.

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 can complete 8–12 residential installations per month in peak season. The limiting factor is usually the installation team (electrical work, DISCOM coordination, and commissioning take 2 days per site) rather than the sales side. To grow beyond 15 installations/month, 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 creates PM Surya Ghar-compliant PDFs in under 60 seconds, manual Excel proposals cost 30–45 minutes each and look unprofessional. (2) A lead CRM to track every enquiry, visit, and follow-up across your team. (3) WhatsApp follow-up tracking so you know which proposals have been seen and which leads need a call. QuickEstimate combines all three in one Android-first app starting at ₹0 (free for 10 proposals/month).
