Solar EPC Case Studies & Results

// Detailed Case Studies

Three Engagements.
Three Very Different Starting Points.

Each solar company came to BG with a different problem — and needed a different solution. What they shared was a commitment to execution and a willingness to build the right system instead of chasing shortcuts.

// The Problem

100% Referral-Dependent. No Digital Presence. Growth Stuck.

Running ₹30L/month entirely on word-of-mouth — 4 years in business

Had tried Facebook ads once, spent ₹40,000, got 2 low-quality leads, stopped

No CRM — all leads tracked in a WhatsApp group and a notebook

Missed 60% of inbound enquiries because no follow-up system existed

Founder doing all sales calls — 12–14 hours/day, no system to delegate

// What BG Built — LT-02 Sprint

One Live Channel, a Landing Page, CRM, and Lead Notification — in 45 Days.

Google Search Ads targeting high-intent residential solar keywords in Pune + surrounding districts

Solar-specific landing page with WhatsApp lead capture, testimonial strip, and urgency trigger

Zoho CRM setup — 5-stage pipeline, lead source tracking, site visit scheduling

WhatsApp auto-notification within 30 seconds of every new lead submission

7-touch follow-up cadence for leads that don't respond within 24 hours

2-hour team handover session — founder + 1 sales exec trained on the full system

// The Outcome — 9 Months

"I had tried digital ads before and it was a disaster. Sandip built something completely different — a system, not a campaign. We now get 40+ solar leads every month and my team handles them without me being involved in every call."

ROI on Engagement

// The Problem

Leads Were Coming In — But 80% Were Being Lost in the Pipeline.

Running Google Ads with ₹60,000/month spend — 35–45 leads/month coming in

Sales team of 4 people, each doing things differently — no unified process

Close rate sitting at 14% for 18 months — founders knew this was too low

No proposal template — every quote sent looked different, many had errors

Follow-up was inconsistent — some leads followed up 5 times, others never called back

Lost deals diagnosed as "price issue" — but the real reason was trust and positioning

// What BG Built — LT-03 SOP Build

Complete Sales Operating System — Scripts, Proposals, CRM, and Team Training.

Solar sales call script — opening, discovery, value framing, and close — residential and C&I versions

Site visit checklist + pre-proposal qualification framework (filters tyre-kickers before visit)

Professional proposal template — ROI calculation built in, objection pre-handled in document

7-touch follow-up cadence — WhatsApp Day 1/3/5/8/15, email Day 2/7, call Day 4

Objection guide — 20 most common solar sales objections with scripted responses

CRM pipeline redesigned — 8 stages with trigger automations and deal health scoring

Full-day team training with role-play — all 4 salespeople live-trained on the new system

// The Outcome — 6 Months

"We thought our problem was the number of leads. BG showed us it was actually our sales process. After the SOP build, our same 4-person team started closing more than double — without a single extra rupee in ad spend."

// The Problem

Strong Execution, Weak Systems — Revenue Plateau at ₹4–5Cr for 2 Years.

Technically excellent company — 200+ installations completed — but growth had stalled completely

Multiple marketing vendors hired and fired — no vendor understood the solar sales cycle

C&I pipeline was inconsistent — big deals came occasionally but no reliable source

Founder was still in every deal — no process to delegate to the sales team

No dashboard — revenue tracked in Excel sheets, pipeline completely invisible

Brand authority was zero online — no case studies, no LinkedIn presence, no reviews system

// What BG Built — Full HT-03 Engagement

Complete 5-Layer Solar Revenue Engine™ — Across All Channels and Systems.

Month 1–2: Growth Diagnostic Audit — 25-page gap report + revenue roadmap delivered

Month 2–3: Multi-channel lead gen live — Google Ads + Meta Ads + LinkedIn outreach for C&I

Month 3–4: Full Zoho CRM + Zoho Analytics dashboard — live pipeline visibility for the first time

Month 4–5: Sales SOP build + team training — 6-person sales team unified on one process

Month 5–7: 4 detailed case studies produced + LinkedIn authority content calendar activated

Month 7–9: Referral engine designed — channel partner onboarding system built

Month 9–12: C&I project pipeline development — 3 enterprise accounts closed directly

"Before BG, I was the business. Every lead, every deal, every decision — me. After 12 months of the Scale Partner engagement, my team runs the pipeline. I stepped into the strategy seat for the first time in 8 years."

// Client Voices

What Solar Founders Say
After Working With BG

Result: ₹28L → ₹85L/month in 8 months

"The biggest shift was not the leads — it was having a system. Before BG, I was chasing every enquiry myself. Now my team handles the full pipeline. I haven't attended a first sales call in 5 months."

Result: Close rate 14% → 31% in 60 days

"We were getting 40 leads a month and closing 5–6. Now we close 12–14 from the same 40 leads. The SOP build paid for itself in the first month. The proposal template alone changed how clients perceive us."

Result: First C&I pipeline built — 3 enterprise accounts closed

"We had no idea how to approach commercial and industrial clients. BG built the entire outreach system — LinkedIn targeting, case study deck, and proposal structure for C&I specifically. We closed our first factory installation in Month 4."

Result: CPL dropped from ₹380 to ₹26 in 45 days

"My previous agency was charging me ₹50,000/month and delivering ₹380 CPL leads that never converted. BG's sprint got me to ₹26 CPL with a 35% site visit conversion in 45 days. That's not an improvement — that's a different world."

// Behind the Numbers

Three Reasons BG Results
Are Consistently Different

The outcomes above don't happen by accident. They are the product of three structural differences in how BG builds and runs every engagement — differences that compound over time.

⚙️

System Design Before Execution

Every engagement starts with diagnosis — understanding your specific market, ICP, competitive landscape, and current gaps — before a single ad is run or a word of copy is written. Generic playbooks don't work in solar. BG builds for your specific situation.

🎯

Solar-Specific Targeting & Messaging

A residential solar buyer in Pune responds to completely different triggers than a C&I procurement officer in Surat. BG's campaigns, scripts, and funnels are built around how Indian solar buyers actually think — not adapted from generic digital marketing templates.

📊

Tracked KPIs With Monthly Accountability

At the start of every engagement month, we set specific targets — lead volume, CPL, pipeline value, close rate. At the end of the month, we review them together. This accountability loop is what forces continuous optimisation instead of letting underperforming campaigns run unchallenged.
