Background
Eltex was thriving with their call center, generating a steady stream of leads through outbound calls and referrals. This approach was working well, helping them establish a strong foothold in the solar market.
Challenge
Despite their call centre success, Eltex’s website was underperforming in lead generation. Their efforts with paid ads weren’t yielding the expected results, and they needed a way to turn website visitors into qualified leads.
Solution
Eltex knew they needed a game-changing solution for their website’s lead generation. They implemented an interactive solar calculator using Convert_, instead of relying on static pages to explain system benefits.
Background
Eltex is a fast-growing solar energy company serving residential and commercial customers across Europe.
They sell and install:
Solar panel systems
Battery storage systems
EV charging stations
Within just two years of operation, the company expanded into multiple markets and continued scaling its installation capacity.
While their outbound call center generated a steady stream of leads, their website was not producing a meaningful volume of leads.
Challenge
The Eltex call center was performing well for generating leads, but their website traffic was underperforming.
Demand for solar energy was increasing rapidly due to rising energy costs and government incentives. Eltex invested in paid ads to capitalize on this demand.
The investment in ads drove more traffic to their website. But despite the increase in visitors, their website conversion performance remained low.
The core problems:
Static content could not clearly communicate system sizing or ROI.
Website visitors could not get immediate answers.
Lead capture relied on basic forms without qualification.
Paid traffic was not producing a proportional return.
Eltex concluded that their solar lead generation funnel was underperforming, not their traffic strategy.
They needed a structured way to:
Educate prospects
Provide tangible value
Capture qualified contact information
Improve PPC efficiency
Solution
Eltex implemented an interactive solar calculator using Convert_.
Instead of relying on static pages to explain system benefits, they created a dynamic lead generation funnel that:
Asks structured qualification questions
Calculates system size and potential savings
Delivers personalized results
Captures contact details before revealing outputs
This shifted the website experience from passive reading to active participation.

How the solar calculator funnel works
Most solar buyers want clarity on three core questions:
What system do I need?
How much will it cost?
How much will I save?
Eltex’s calculator guides users through inputs such as:
Roof type
Average electricity bill
Electrical requirements
Desired warranty length
Age of property
Instead of showing the results immediately on screen, users are prompted to submit their contact information to receive personalized results via email.
This structure accomplishes two things:
It maximizes lead capture.
It filters high-intent prospects.
Prospects who complete the form and submit contact details are already engaged and solution-aware.
Why Convert_ enabled this shift
Eltex selected Convert_ because it allowed them to build a calculation-driven solar lead generation funnel without custom development.

Results
After launching the interactive solar sales funnel, results were immediate and measurable.
30 qualified leads per day
Eltex now generates approximately 30 online leads daily through their website calculator funnel.
Over 1,000 leads per month
The calculator consistently delivers over 1,000 new leads per month.
2,000–5,000 monthly interactions
Thousands of visitors actively engage with the calculator each month, providing valuable interaction data.
Improved PPC efficiency
Higher conversion rates allowed the marketing team to increase ad spend while maintaining a stronger return on ad spend.
Surpassed call center performance
The automated online funnel started generating more leads than Eltex’s outbound call center. Digital solar lead generation became a primary growth engine.
Lead qualification and data intelligence
Beyond lead volume, the calculator provided deeper insights into their customers. Analyzing form interactions helps Eltex identify:
Average system demand
Common budget ranges
Interest in warranties and add-ons
This enables more personalized follow-up from sales teams and improves closing efficiency.
Because results are delivered by email, Eltex opens communication channels early in the buying journey. Even if prospects do not convert immediately, they can be nurtured through CRM workflows.
Expanding the funnel
After early success, Eltex launched additional calculators and temporary promotional funnels across its marketing website.
Interactive funnels now support:
Seasonal promotions
Special offers
Regional campaigns
Targeted PPC landing pages
Each funnel is structured to maximize engagement and capture qualified leads before revealing results.
Why This Matters for Solar Installation Companies
Solar buyers need clarity before committing. But static pages rarely provide:
Personalized ROI estimates
Instant system sizing
Immediate cost projections
Interactive calculator funnels replace generic marketing content with tangible, data-driven value. For solar companies running paid ads, improving the conversion rate directly impacts profitability.
Instead of sending traffic to static pages, directing it to a structured calculator funnel can:
Increase engagement
Improve lead qualification
Reduce sales friction
Strengthen ROAS
