Every solar EPC founder running paid ads eventually asks this question: where should I put my budget — Google or Meta? Most make the decision based on what their peer is doing, or what an agency recommended without fully understanding the business. The result is often wasted budget and a conclusion that "digital ads don't work for solar."
They do work — but the platform choice has to match your customer segment, your sales cycle, and your current stage of business. Here's the framework I use with every solar EPC client.
The Fundamental Difference: Intent vs Awareness
Google Search Ads capture intent. Someone searching "solar panel installation Pune" or "rooftop solar for factory Maharashtra" is actively looking for a solution right now. They've already decided they want solar — you just need to be visible when they search. The lead quality from search ads is generally high because there's a declared need behind the click.
Meta Ads (Facebook and Instagram) create awareness. You're reaching people while they're scrolling through social feeds — they aren't searching for solar, but your ad interrupts their scroll and hopefully sparks interest. The lead quality is typically lower because the intent wasn't there to begin with; you're generating demand, not capturing it.
Neither is universally better. The question is: which one fits your segment?
Google Ads: Best for C&I and Commercial Solar
Commercial and industrial buyers — factory owners, warehouse operators, hospital administrators, large housing societies — typically begin their solar journey with a Google search. They have a defined problem (high electricity bills, power reliability) and they search for solutions deliberately.
For these segments, Google Search Ads are the right starting point. A well-structured campaign targeting keywords like "commercial solar installation [city]", "industrial solar EPC", "100kW solar system cost", or "MNRE approved solar installer" will capture buyers who are already in evaluation mode. These leads convert better and faster because the intent is pre-qualified.
Realistic CPL benchmarks for Google Search (India, 2025–26):
- Commercial/C&I leads (50kW+): ₹800 – ₹2,000 per lead
- Residential leads via search: ₹400 – ₹900 per lead
- High-competition cities (Mumbai, Bengaluru, Pune): ₹1,200 – ₹2,500 per lead
Google costs more per lead, but the conversion rate is higher. A ₹1,500 Google lead that converts at 25% is more valuable than a ₹400 Meta lead that converts at 5%.
Meta Ads: Best for Residential Rooftop
For residential rooftop — homeowners considering a 3–10kW system — Meta outperforms Google in most markets. Homeowners don't always search for solar proactively; they see a neighbour's installation, notice a solar ad, or read a post about electricity bills and become curious. Meta is excellent at finding and activating this latent interest.
Facebook Lead Ads with a simple form (name, phone, city, approximate electricity bill) work extremely well for residential solar. The targeting options — interest in home improvement, specific income brackets, homeowner demographics, geography down to pin code — let you reach the right audience efficiently.
Realistic CPL benchmarks for Meta Lead Ads (India, 2025–26):
- Residential rooftop (3–10kW): ₹150 – ₹500 per lead
- Rural/tier 2 markets: ₹80 – ₹250 per lead
- Higher-income urban targeting: ₹400 – ₹800 per lead
Meta leads are cheaper, but the follow-up speed and quality of your response system determines whether they convert. A Meta lead goes cold in 2–3 hours if not contacted. Your enquiry response protocol (see our article on that) matters enormously here.
For a solar EPC company running both channels, a monthly budget of ₹30,000–₹50,000 is the minimum to get statistically meaningful data. Below this, you don't have enough lead volume to optimise. Split ₹15,000–₹25,000 per platform in month one, measure CPL and conversion rate, then shift budget toward whichever performs better for your specific segment and geography.
What Stage of Business Are You At?
Platform choice also depends on your business maturity. If you're doing fewer than 5 projects per month and your primary segment is residential, start with Meta. Lower entry cost, faster feedback loop, easier to manage in-house with basic training.
If you're doing 8–15 projects per month and want to move into C&I, Google is the right investment. The higher CPL is justified by ticket size — a 100kW commercial project at ₹40–60 lakh makes a ₹1,500 lead cost irrelevant.
If you're at ₹1 crore/month revenue and above, you should be running both — Meta for residential demand generation and retargeting, Google for commercial intent capture. These aren't competing channels; they serve different buyer journeys.
The Landing Page Problem Nobody Talks About
Bad landing pages kill good ad campaigns. If you're sending paid traffic to your homepage or a generic "contact us" page, you're wasting budget regardless of how well the ad is written. Every paid campaign needs a dedicated landing page that matches the ad's promise, loads in under 3 seconds on mobile, and has a single clear action (form fill or call button).
This is one of the most common reasons solar companies report that "ads don't work" — the ads are fine, the landing page experience is poor.
Tracking: The Non-Negotiable
You must track which leads came from which platform, and which of those leads actually converted into projects. Most solar companies track CPL (cost per lead) but not cost per closed project. A platform that delivers cheap leads that never convert is more expensive than one that delivers fewer, pricier leads that close at 30%.
Set up: Google Analytics 4 (GA4), Meta Pixel, and a CRM with lead source tracking. This doesn't require a developer — it's a one-day setup with the right guidance. Without this data, you're making platform decisions based on gut feeling, not evidence.
