Key takeaway: Solar EPCs that score leads before follow-up close 2.3x more deals with the same headcount. The Solar Lead Score Matrix gives every inbound lead a number from 0 to 100, and tells your rep whether to call today, nurture next week, or park the contact until the season changes.

Rohit runs a 12-person solar EPC team in Surat. His sales reps come in each morning, open their CRM, and stare at 40 leads, some submitted this morning, some from three months ago, all listed in the same colour. By noon, two reps have spent four hours chasing a tenant who cannot sign anything and a builder who already placed an order with a competitor.

Sound familiar?

The problem is not the number of leads. According to a CEEW consumer survey (2024), residential solar inquiries in Gujarat alone rose 38% year-on-year after PM Surya Ghar registrations crossed 1 crore. The problem is prioritisation. Without a score, every lead looks equally worthy of a phone call, and your most expensive resource, a trained solar sales rep, burns time on contacts that were never going to convert.

This guide builds "The Solar Lead Score Matrix" from first principles: what to measure, how to weight it, how to configure it in your CRM, and what to do with each score band.


Why Most Solar EPCs Waste 60% of Their Follow-Up Time on Wrong Leads

Ask any solar sales manager in India to estimate what fraction of their follow-up effort goes to leads that never convert. The honest answers cluster around 50–70%.

JMK Research (2025) benchmarks residential solar lead-to-closure rates in India at 8–12% for unscored pipelines. For EPCs that apply any form of qualification scoring, that rate rises to 18–24%. The delta is not magic, it is simply rep time redirected from dead-end contacts to serious buyers.

Three patterns drive the waste:

First-come, first-served follow-up. Reps call whoever submitted the form most recently, regardless of property type, bill size, or intent signals. A fresh lead from a renter gets the same urgency as a rooftop-owning factory manager with a ₹4 lakh monthly electricity bill.

No decay model. A lead that opened your proposal four times last Tuesday is worth 10x a lead that has not replied to three WhatsApp messages in two weeks. Without engagement tracking, both sit in the same queue.

Ignoring DISCOM geography. Net metering approval timelines vary dramatically. MGVCL in Gujarat processes applications in roughly 30 days; some state DISCOMs take four to six months. A homeowner in an active DISCOM zone should score higher than an equivalent prospect in a zone with a 180-day backlog, the latter will likely lose interest before the paperwork clears.

If you want a deeper look at how lead flow connects to your broader process, the solar sales funnel guide for India explains each stage from inquiry to commission.


What Lead Scoring Actually Means in a Solar CRM Context

Lead scoring is a method of assigning a numeric value to each lead based on attributes (who they are) and behaviour (what they have done). The resulting number predicts conversion likelihood, so you can sort your pipeline by expected revenue rather than by timestamp.

In a general B2B CRM, scoring typically separates Marketing Qualified Leads (MQLs) from Sales Qualified Leads (SQLs). Solar EPCs need something more granular because the variables that predict solar conversion are highly domain-specific:

  • Does the prospect own the property?
  • Is the monthly electricity bill high enough to justify the system size?
  • Is the local DISCOM offering live net metering with a short approval queue?
  • Has the prospect requested a site survey, the single strongest intent signal in residential solar sales?

A generic CRM score based on "downloaded a whitepaper" will not capture any of this. You need a solar-native scoring model, which is exactly what The Solar Lead Score Matrix provides.

For more on what a fully configured CRM should look like for an EPC, read the solar CRM buyer's guide.


The Solar Lead Score Matrix

The matrix works on two axes. Each axis contributes up to 50 points, giving a maximum total of 100.

Axis 1
Prospect Fit
Who they are, property type, system size appetite, decision-maker role, DISCOM net metering status. Max 50 points.
Axis 2
Engagement Score
What they have done, proposal opens, WhatsApp replies, site survey requests, referral source. Max 50 points.

Score bands and routing rules:

  1. ≥ 60
    Hot Lead, Same-day rep call
    Assign to senior rep within 4 business hours. Send personalised proposal if not already done. Log call outcome in CRM.
  2. 30–59
    Warm Lead, Nurture automation
    Enrol in WhatsApp drip sequence: savings calculator, subsidy explainer, EMI guide. Re-score after each interaction. Escalate if score crosses 60.
  3. < 30
    Cold Lead, Park and monitor
    Tag as "cold" and exclude from rep queue. Add to a monthly broadcast list. Revisit if DISCOM zone activates net metering or subsidy policy changes.

The logic is simple: your reps should spend their energy where the probability-weighted revenue is highest. This matrix makes that calculation automatic.


Scoring on Prospect Fit: Property, System Size, Decision-Maker, DISCOM Location

Prospect Fit answers the question: even if this person wanted to buy today, could they? A tenant in a rented flat cannot sign a net metering application. A DG-set-dependent factory with a ₹8 lakh monthly bill can, and will.

Attribute Signal Points
Property Type Own residential rooftop (independent house / villa) 15
Commercial / industrial rooftop (owned) 15
Society / apartment (common area only) 7
Rented / cannot install 0
System Size Appetite Monthly bill ≥ ₹8,000 (likely 5+ kW system) 10
Monthly bill ₹3,000–₹7,999 (2–4 kW system) 6
Monthly bill < ₹3,000 (≤1 kW, subsidy-only buyer) 2
Decision-Maker Role Owner / director / MD (can sign today) 15
Facilities / maintenance manager (influencer) 8
Unknown / not captured 3
DISCOM Net Metering Status Active zone, approval < 45 days (e.g. MGVCL, BESCOM) 10
Active zone, approval 45–90 days 6
Net metering pending / backlog > 90 days 1

Maximum Prospect Fit score: 50 points (15 property + 10 system size + 15 decision-maker + 10 DISCOM).

Tip: PIN code-to-DISCOM mapping can be embedded in your CRM intake form as a dropdown. When the prospect enters their PIN, the form auto-fills the DISCOM zone and flags the net metering approval time. Your rep sees the score before picking up the phone. The qualifying solar leads guide has a PIN-code field template you can copy.

You can read more on how the lead management workflow connects intake forms to CRM scoring in practice.


Scoring on Engagement: Proposal Opens, WhatsApp Replies, Referral Source

Prospect Fit tells you who could buy. Engagement tells you who wants to buy right now. A high-fit lead who ignores every message is a lower priority than a medium-fit lead who has opened your proposal twice and asked about EMI options.

+15
Site survey requested
+10
Proposal opened ≥ 2×
+10
Referral (existing customer)
+8
WhatsApp reply within 24h

Full engagement scoring table:

Behaviour What it signals Points
Site survey explicitly requested Highest purchase intent; prospect is ready to move +15
Proposal opened ≥ 2 times Actively reviewing; likely sharing internally +10
Inbound referral (from existing customer) Pre-sold by peer trust; highest close rate source +10
WhatsApp reply within 24 hours Responsive; open to conversation +8
Proposal opened once Moderate interest; follow up with value content +5
Inbound from Google / organic Self-directed research; higher intent than ads +5
Inbound from Facebook / paid ad Curiosity-stage; needs more nurturing +3
No reply after 3 WhatsApp messages Disengaged; score decays -5
Proposal not opened after 7 days Cold; no visible intent -4
Note on referral source: According to JMK Research (2025), referral leads in the residential solar segment close at 3.1x the rate of paid-ad leads and require 40% fewer touchpoints. If your CRM can tag the referral source at intake, that single data point is worth more than any other engagement signal. Read the solar lead management best practices article for how to structure intake forms that capture referral source reliably.

A related metric to track alongside your engagement score is cost per lead by channel, the cost per solar lead in India breakdown shows how much you are paying per inquiry from each source, which helps you weight referral and organic leads correctly in the matrix.


How to Set Up Lead Scoring in Your Solar CRM

  1. 1
    Audit your intake form fields
    Make sure your lead capture form collects property type, monthly bill, owner vs renter, and PIN code. If any of these are missing, you cannot compute Prospect Fit. Add mandatory fields before you configure scoring.
  2. 2
    Build your DISCOM zone lookup table
    Create a spreadsheet mapping PIN code ranges to DISCOM name and net metering approval SLA. Import this into your CRM as a picklist so that when a rep enters a PIN, the DISCOM score auto-populates. Reference MNRE's net metering state-wise data (2025) for SLA estimates.
  3. 3
    Configure score fields in CRM
    Add two numeric custom fields: "Prospect Fit Score" (0–50) and "Engagement Score" (0–50). Create a formula field "Total Lead Score" that sums both. Most solar CRMs support formula fields natively. Set the lead list default sort to Total Lead Score descending.
  4. 4
    Set up engagement triggers
    Connect proposal tracking (email/WhatsApp delivery receipts and open events) to an automation that adds points to Engagement Score when triggered. When a prospect opens a proposal, +5 is added. On second open, another +5. On site survey form submission, +15. This should require no manual rep entry.
  5. 5
    Create routing automations by score band
    Build three workflow rules: if Total Lead Score ≥ 60 → assign to senior rep + send Slack/WhatsApp alert; if score 30–59 → enrol in nurture sequence; if score < 30 → tag "cold" + remove from active rep view. Test with 10 historical leads before going live.
  6. 6
    Review and recalibrate monthly
    Pull a report at month-end showing closed deals by score band. If your hot leads are not closing at ≥ 20%, your Prospect Fit weights need adjusting. If warm leads are converting below 8%, check whether your nurture sequence is actually delivering. The CRM dashboard guide has report templates for this.
Warning: Do not rely on reps to manually update engagement scores. Human-entered scores decay in accuracy within two weeks because reps forget to log every WhatsApp message. Your engagement scoring must be event-driven and automated, or it will not work.

Routing Rules: Hot vs Warm vs Cold Leads

Once a lead has a score, the routing rule is what actually changes rep behaviour. Here is a complete grid of how each band should be handled.

Hot (≥ 60)
Warm (30–59)
Cold (< 30)
Assign to
Senior closer
Junior rep / automation
No rep assigned
First touch
Phone call within 4 hours
WhatsApp message within 24h
Monthly broadcast only
Nurture sequence
Personalised proposal + site survey booking
Savings calculator → subsidy guide → EMI options (3-part drip)
Policy update alerts + seasonal promotions
Re-score trigger
Score reviewed after every call
Auto re-score on each engagement event
Re-score quarterly or on policy change
Rep hours per lead
3–5 hours active selling
0.5–1 hour over 2–4 weeks
0 rep hours (fully automated)

The solar lead follow-up cadence article explains how to space WhatsApp and phone touchpoints for warm leads so you stay visible without being intrusive. Pair that with the solar pipeline stages guide to understand which stage each score band maps to.


Revenue Impact: Closing Rate Improvement with Scored vs Unscored Leads

Let us put real numbers to this. The scenario below is based on a 12-person EPC team running 120 new leads per month, numbers typical for a Tier-2 city operation according to Mercom India's Q1 2025 rooftop market report.

Money Math
Without lead scoring:
  • 120 leads/month × 10% close rate = 12 deals
  • Average deal value: ₹1.8 lakh (3 kW residential at ₹60/W installed)
  • Monthly revenue: 12 × ₹1.8 lakh = ₹21.6 lakh
  • Rep hours wasted on cold leads: ~65% of 400 total hours = 260 hours @ ₹250/hr = ₹65,000 lost
With Solar Lead Score Matrix (scored pipeline):
  • Hot leads (score ≥ 60): ~24 leads × 22% close rate = 5.3 deals
  • Warm leads (30–59): ~48 leads × 14% close rate = 6.7 deals
  • Cold leads (< 30): ~48 leads, no rep time spent = 0 deals (automated only)
  • Total deals: 5.3 + 6.7 = 12 deals → but rep hours freed allow pursuing 30 more warm leads from backlog: +4.2 deals
  • Total deals: 16.2 per month (35% uplift)
  • Monthly revenue: 16.2 × ₹1.8 lakh = ₹29.2 lakh (vs ₹21.6 lakh)
Annual revenue delta: ₹91.2 lakh from the same team, same leads, same budget.

The math above uses conservative close rate assumptions from JMK Research's 2025 India solar sales benchmark. Your actual uplift will depend on your starting close rate and how disciplined your reps are about following the routing rules.

How QuickEstimate Fits

QuickEstimate is built around the same workflow logic as the Solar Lead Score Matrix. Here is exactly where it connects to each scoring step:

  • Lead capture with scoring fields built in: The lead capture module includes property type, monthly bill, owner/renter toggle, and PIN code as standard fields, everything the Prospect Fit axis needs at intake.
  • Proposal open tracking for engagement scoring: The proposal generator tracks every open and timestamps it against the lead record. Your engagement score updates automatically when a prospect opens a proposal, no rep action needed.
  • WhatsApp reply tracking for engagement axis: WhatsApp follow-up logs inbound replies to lead records and can trigger score increment rules when a prospect responds within your defined window.
  • Score-sorted pipeline view: The pipeline management board lets you sort and filter leads by any numeric field, including your Total Lead Score. Your reps see hot leads at the top of the list every morning without any manual sorting.
  • Closing rate by score band in reports: Sales reports include conversion rate broken down by custom field, so you can see exactly whether your hot, warm, and cold bands are hitting their benchmarks each month and recalibrate weights accordingly.

What to Do This Week

You do not need to implement the full matrix on day one. Here is a five-day plan:

Monday: Audit your current intake form. Add property type, monthly bill, owner/renter, and PIN code if they are missing. Even a manual entry field gets you started.

Tuesday: Export your last 60 leads. Manually score 20 of them using the Prospect Fit table above (ignore Engagement for now). Look at the top 10 scores, were those the leads your reps already prioritised intuitively? If yes, the matrix is calibrating correctly.

Wednesday: Set up three tags in your CRM: "Hot," "Warm," "Cold." Manually tag the 60 leads you scored. Reassign any hot leads that are sitting unworked.

Thursday: Brief your reps on the routing rule: any lead tagged Hot gets a phone call by end of day. Show them the score, not just the tag, so they understand the reasoning.

Friday: Review the week. How many hot leads were contacted? What was the call-to-meeting conversion? Set a 30-day target for close rate on scored leads and use the sales reports dashboard to track it.

Frequently Asked Questions

What is lead scoring in a solar CRM?
Lead scoring assigns a numeric value (0–100) to each prospect based on who they are (Prospect Fit: property ownership, bill size, role, DISCOM zone) and what they have done (Engagement: proposal opens, WhatsApp replies, site survey requests). The total score tells your rep whether to call today, nurture automatically, or park the contact.
What score should I use as the hot lead threshold?
The Solar Lead Score Matrix uses ≥ 60 as the hot threshold. This means the lead must score at least moderately well on both axes, a very high Prospect Fit with zero engagement, or vice versa, will not cross 60. Adjust the threshold based on your team capacity: if you have capacity for 15 hot-lead calls per week but the matrix is generating 30, raise the threshold to 65 or 70.
Does lead scoring work for commercial solar leads as well as residential?
Yes, but the weights change. For C&I leads, system size appetite (monthly bill) should carry more weight, raise it from 10 points to 15 and reduce the DISCOM location weight slightly, since C&I buyers often proceed even in longer-approval zones because the ROI is larger. Decision-maker role remains equally important: a factory owner scores 15, but a procurement officer scores 6–8.
How often should lead scores be recalculated?
Prospect Fit scores should be recalculated whenever the rep updates a field (e.g., discovers the lead is a tenant, not an owner). Engagement scores should update in real-time on each trigger event, proposal open, WhatsApp reply, site survey submission. A weekly score refresh report helps catch leads that have decayed (no engagement in 14+ days) so reps can decide whether to close or reactivate.
What if I do not have proposal tracking set up?
Start with Prospect Fit scoring only (max 50 points), and use a lower threshold, score ≥ 35 = hot, 20–34 = warm, < 20 = cold. Add Engagement scoring once you have a proposal tool with open tracking. Even a partial scoring system outperforms no scoring: focusing reps on high-fit leads alone will improve conversion rates.
Can I score leads from Facebook ads differently from referral leads?
Yes, and you should. The engagement scoring table assigns +10 to referral leads and +3 to Facebook ad leads. This means a referral with the same Prospect Fit as an ad lead starts with a 7-point engagement advantage, which is the correct reflection of real-world close rate differences. Tag referral source at intake and let the scoring do the rest.
What is the difference between an MQL and a SQL in solar sales?
A Marketing Qualified Lead (MQL) has shown interest, they filled a form, downloaded a guide, or replied to an ad. A Sales Qualified Lead (SQL) has been verified by a rep or scoring system as having real purchase potential. In the Solar Lead Score Matrix, a score of 30–59 approximates MQL (worth nurturing but not yet rep-assigned) and ≥ 60 approximates SQL (ready for direct rep engagement).
How does PM Surya Ghar affect lead scoring?
PM Surya Ghar subsidy eligibility increases a lead's urgency and reduces price objection, but only if the property qualifies (owned residential, below 10 kW, connected to grid). Consider adding a +5 bonus to Prospect Fit for leads that confirm PM Surya Ghar eligibility at intake. The official PM Surya Ghar portal has the latest eligibility criteria and empanelled vendor list.
