Solar lead generation in India: 14 sources for EPCs

Solar lead generation is the work of getting a steady flow of people who want a solar system to raise their hand — and in India that means running several channels at once, because no single source fills an EPC’s pipeline. Some sources are free and full of intent. Some cost money and are shared with rivals. The skill is knowing which is which, and then not wasting the leads you paid for.

This guide is for the rooftop or C&I EPC owner asking a simple, urgent question: where do I actually find customers? Below are the 14 sources that work in India, scored on cost, lead quality and effort, so you can see at a glance which to start with. Then we cover the part that decides whether any of it pays off — turning raw enquiries into signed jobs.

What is solar lead generation for an EPC?

Solar lead generation is the ongoing job of feeding your pipeline with people who want a solar system, from enough different sources that the flow never dries up. For an Indian EPC it is not one activity — it is a portfolio. You run free channels and paid ones, online and offline, warm and cold, all at the same time.

The reason is simple. A single rooftop system is a low-margin, considered purchase. You make money on throughput, so you need volume. But volume from the wrong source — cold, shared, price-shopping leads — can cost more to chase than it earns. Good lead generation balances two numbers per source: how many enquiries it brings, and how well they convert. The second number is the one most EPCs forget to measure.

The 14 solar lead sources for Indian EPCs, scored

Here are the 14 lead sources that actually generate rooftop and C&I solar business in India, scored on cost, intent, effort and who each suits best. Read the table as a menu, not a to-do list — you will pick a handful, not all of them.

One pattern jumps out. The best sources — referrals, the portal, your AMC base — are free or nearly free, because intent, not spend, is what makes a lead convert. Paid sources have a place, but they are shared and price-led, so they only pay off if you respond faster than the other installers who bought the same lead.

How do you work the high-intent free sources?

The highest-return sources cost almost nothing, so build a habit around each one instead of a budget. These are the leads that close, and most EPCs under-work them because they are chasing shinier paid channels.

PM Surya Ghar National Portal. Anyone who reaches the portal has already decided to go solar — that is as high-intent as it gets. Registration is free; the work is empanelling with each DISCOM and staying active. Treat the portal as a core channel, not an afterthought. Our PM Surya Ghar guide for EPC contractors walks the registration and application flow end to end.

Referrals and word-of-mouth. A referred customer trusts you before the first call, so these leads convert best and cost least. The catch is they only flow if you deliver well and ask — at handover, and again after the first AMC visit. Make asking part of the process, not a favour you remember sometimes.

Existing customers and your AMC base. Every plant you service is a live lead: a bigger system, a second property, a neighbour, a battery add-on. Your maintenance base is the cheapest pipeline you own, and reminders are all it needs. This is one reason we treat AMC as a growth engine, not just a service.

How do you work paid marketplaces and ads?

Paid sources bring volume, but the same lead is sold to several installers — so speed, not price, decides who wins. If you buy leads and answer them tomorrow, you are paying to warm up a customer for whoever called first.

IndiaMART, JustDial and Sulekha. These marketplaces are worth testing, especially IndiaMART for C&I and dealer enquiries. The rule for all three is the same: reply within minutes, send an indicative quote the same day, and follow up on a fixed cadence. IndiaMART leads can flow straight into your CRM so no enquiry sits unseen — that is exactly what our IndiaMART integration does. We go deeper on making that channel pay in how to actually close IndiaMART solar leads.

Meta and Instagram ads. Ads reach people who were not searching, so intent is lower and every lead needs nurturing. They work when your creative is honest, your qualification is tight, and your follow-up is disciplined. Do not judge them on cost per lead — judge them on cost per closed job, which is often a very different number.

The common thread across every paid source is speed-to-lead. A shared lead is a race, and the winner is usually the first credible reply. That is an operations capability, not a marketing one — which is the whole point of the next two sections.

What about the sources you own and build?

Owned and community sources are slow to start but compound over time, and they cannot be outbid by a competitor. These are the channels that make a local EPC the obvious choice in its town.

• Google and local SEO. A complete Google Business Profile with reviews puts you in front of people actively searching “solar installer near me.” It is high-intent and mostly free, but it takes months of reviews and content to rank. Start now; it pays later.
• WhatsApp. Not really a source of new leads so much as the way you nurture every other source. India lives on WhatsApp, so quotes, reminders and re-engagement land better here than on email — if every touch is logged against the lead.
• Exhibitions, melas and camps. Face-to-face events build trust fast and can fill a region’s pipeline in a weekend. They cost time and money, so capture every visitor into your CRM the same day, before the cards go cold.
• RWA and society tie-ups. One relationship with a housing society can unlock dozens of rooftops and a common-area project. High intent, bulk volume, and a trusted anchor make this one of the best offline plays.
• Channel partners, dealers, telecalling and hoardings. These extend reach — partners on commission, dealers for referrals, calling to fill a young pipeline, hoardings for recall. Manage them as a network, and tag their leads so you know which partner actually delivers.

Which sources give the best ROI for a small EPC?

For a small EPC, the best ROI comes from running three to five sources well — not fourteen badly. A tiny budget spread across every channel wins none of them. Sequence matters more than breadth: win one source, then add the next.

Whatever mix you pick, the measure that matters is cost per closed job by source, not cost per lead. A source that hands you cheap enquiries that never convert is expensive. A source that costs more but closes reliably is cheap. You can only see the difference if you tag every lead by where it came from — which brings us to the real problem.

Why is not losing leads harder than generating them?

Generating leads is the easy part; not losing them is where most EPCs quietly bleed money. You can pour budget into all 14 sources, but if enquiries land in three WhatsApp chats, a diary and someone’s phone, a large share dies unseen — unowned and un-followed-up.

Two failures do most of the damage. First, slow response: on shared paid leads, the first installer to reply usually wins, so a lead answered tomorrow is often already lost. Second, no follow-up cadence: most solar sales need several touches, but a busy owner remembers the first and forgets the rest. A reheated warm lead converts better than a cold new one — and it costs nothing.

The fix is not more leads. It is a solar CRM that captures every source into one list, assigns an owner, and drives a reminder-based follow-up until the customer decides. We break down the pipeline, the follow-up rhythm and lead scoring in the solar CRM guide for India. Pair fast, accurate quoting from a maintained rate card — the job of solar quotation software — and speed-to-lead stops being a slogan and becomes a habit.

Capturing every source into one CRM with SuryaHub

SuryaHub pulls leads from every source into one record, gives each an owner, and keeps follow-up on a schedule — so the leads you work hard to generate actually turn into jobs. A marketplace enquiry, a portal lead, a referral and a WhatsApp message all land in the same list, with the same stages and the same reminders.

• Capture every enquiry — IndiaMART, portal, referral, WhatsApp — into one funnel, tagged by source.
• Route each lead to an owner by territory, so there is one person accountable for every enquiry.
• Follow up on a reminder-driven cadence, so no warm lead goes cold because someone forgot.
• Convert a qualified lead straight into a job file — no re-typing — and quote fast from a rate card.

Here is the honest part. SuryaHub is pre-revenue and building alongside two pilot EPCs, Suryantra Energy and RGESPL. We will not show you invented lead counts, fake testimonials or a wall of customers who do not exist. What we can say plainly is what this guide argues: the EPCs that win are not the ones with the most lead sources — they are the ones who lose the fewest leads. SuryaHub is built to make that the default.

Frequently asked questions

Where can a solar EPC get leads in India?

A solar EPC in India can get leads from 14 main sources: the PM Surya Ghar National Portal, referrals, IndiaMART, JustDial, Sulekha, Google and local SEO, Meta and Instagram ads, WhatsApp, exhibitions and melas, RWA and society tie-ups, channel partners, existing-customer upsell, telecalling, and hoardings. They differ hugely in cost, intent and effort, so test a few and track which ones actually convert.

Which solar lead source is cheapest for an EPC?

Referrals and your existing-customer base are the cheapest solar lead sources, because they cost almost nothing and carry the highest intent. A happy customer or a well-serviced AMC account trusts you before you speak, so these leads close faster and at lower cost than any paid source. The catch is that they only flow if you deliver well and ask for the referral on a schedule.

What is the best lead source for a new or small solar EPC?

For a new or small solar EPC, the best starting mix is referrals, the PM Surya Ghar portal, a Google Business Profile, and one paid marketplace such as IndiaMART or JustDial. This blend costs little, carries high intent, and builds a pipeline fast. Avoid spreading a tiny budget across every channel at once; win one source, then add the next.

Do paid solar leads from IndiaMART or JustDial convert?

Paid solar leads from IndiaMART and JustDial do convert, but the same enquiry is usually sold to several installers, so the fastest responder wins. Speed-to-lead matters more than price here: reply within minutes, send an indicative quote the same day, and follow up on a fixed cadence. Track cost per closed job by source, not cost per lead, to see if a marketplace actually pays.

Are PM Surya Ghar portal leads free?

Registering on the PM Surya Ghar National Portal is free, and applicants who reach it have already decided to go solar, so their intent is high. You still have to empanel with each DISCOM and work the portal actively. The lead itself carries no per-lead cost, which makes the portal one of the highest-value sources for any residential rooftop EPC in India.

How do I stop losing solar leads after I generate them?

Stop losing solar leads by capturing every enquiry into one CRM, assigning an owner, and following up on a fixed schedule until the customer says yes or no. Most EPCs lose more revenue to slow or forgotten follow-up than to a lack of leads. Speed-to-lead and a logged, reminder-driven cadence beat any new lead source, because a reheated warm lead converts better than a cold new one.

How many lead sources should a small solar EPC use?

A small solar EPC should run three to five lead sources well, not fourteen badly. Pick a couple of high-intent free sources like referrals and the PM Surya Ghar portal, add a Google Business Profile, and test one paid channel. Tag every enquiry by source so you can see cost per closed job, then double down on what converts and drop what only feels busy.
