Your solar clients are an untapped goldmine
While you’re investing heavily in acquiring new customers, a treasure trove of opportunity sits neglected in your existing client list. Let’s explore why your solar clients are an untapped goldmine and your most valuable asset for generating high-quality battery leads, EV charger leads, and heat pump leads without the high acquisition costs.
The Economics of Customer Relationships: Numbers Don’t Lie
Consider these revealing statistics:
- The average solar installer spends €20 to acquire a new lead from a lead list
- New lead conversion rates from lists hover around 10% at best
While:
- Existing customer conversion rates reach approximately 50%
- Referrals from satisfied customers convert at similarly high rates

What most people forget is that your solar clients are an untapped goldmine. When you factor in the time spent processing each lead (about €50 worth of work per lead), the true cost difference becomes staggering: approximately €700 to convert a cold lead versus just €140 for a warm lead from your existing portfolio.
Despite these numbers, most installers treat customer relationships as transactional rather than ongoing partnerships. This “install and forget” approach leaves a lot of revenue on the table while opening the door for competitors.
Your Solar Customers Want More Than Just PV Systems
The homeowner who trusted you with their solar installation journey is likely to be interested in complementary energy products:
- Battery storage systems to maximise their solar investment
- EV chargers as they transition to electric vehicles
- Heat pumps to further reduce their carbon footprint and energy costs
These aren’t just cross-selling opportunities. They’re relationship-deepening moments that create value for both you and your customers. By positioning yourself as their trusted energy advisor, you transform one-time projects into ongoing partnerships.
The “Set It and Forget It” Trap That’s Costing You Revenue
A common pattern is noticeable across the industry: installers invest heavily in winning customers and delivering excellent installations, only to disappear afterward. The only subsequent contact often comes if something goes wrong.
During this silence, your competitors aren’t standing still. They’re actively approaching your customers with offers for batteries, EV chargers, and heat pumps.

Why Staying Connected Is Challenging (But Essential)
Maintaining meaningful relationships with your customer base presents several obstacles:
- Generic newsletters achieve only 15-25% open rates
- Creating valuable, relevant content requires significant time investment
- Identifying when customers are ready for upgrades feels like guesswork
- Manual follow-up processes are labor-intensive and often inconsistent
These challenges explain why many installers focus on purchasing new PV lead lists rather than nurturing existing relationships. But this approach leaves your most valuable asset untapped.
Automated Customer Engagement: The Solution for Generating Premium Leads
What if you could maintain meaningful connections with your entire customer base while simultaneously generating high-quality battery leads, EV charger leads, and heat pump leads?
This is precisely what automated customer relationship platforms can deliver. By providing personalised, valuable information to customers while seamlessly integrating relevant offers, these systems transform your existing customer database into your most reliable lead source.
How Automated Customer Engagement Works
An effective automated engagement system operates on two key principles:
- Deliver genuine value first: Customers receive personalised reports showing their specific solar system’s performance, addressing their primary concern: is my investment working as promised?
- Integrate relevant offers naturally: Within these high-value communications, targeted offers for batteries, heat pumps, EV chargers, and other products appear as helpful suggestions rather than pushy sales pitches.
This is exactly what Connect+ does.

The Remarkable Results of Personalised Engagement
When we look at the results of Connect+, you see this approach generates impressive outcomes:
- 70% average open rates on personalised performance reports. This is nearly triple the engagement of typical newsletters
- Minimal time investment required as the system automates data collection and report generation
- Higher conversion rates as offers reach customers at relevant moments in their decision making process
- Strengthened customer relationships that lead to additional referrals and positive reviews
Beyond Lead Generation: Building a Sustainable Business
While immediate lead generation for batteries, EV chargers, and heat pumps is valuable, the long-term benefits of customer engagement extend further:
- Reduced customer acquisition costs as more business comes from existing relationships
- Higher lifetime customer value through multiple purchases over time
- Enhanced reputation in your market as a trusted energy advisor
- Competitive differentiation in an increasingly crowded marketplace
Transform Your Customer Database Into Your Most Valuable Asset
Rather than continuously investing in expensive PV lead lists, battery leads, EV charger leads, and heat pump leads from external sources, consider how activating your existing customer relationships could transform your business economics.
The homeowners who already trust you represent your most efficient path to growth. Particularly as the energy transition accelerates and more households seek comprehensive energy solutions.
By implementing an automated customer engagement strategy, you can simultaneously strengthen relationships, generate high-quality leads, and position your business for sustainable growth in the expanding clean energy marketplace.
Next Steps: Evaluate Your Customer Engagement Strategy
Take a moment to assess your current approach to customer relationships:
- How frequently do you communicate with past customers?
- What percentage of your new business comes from existing customers or referrals?
- Are you systematically offering complementary products like batteries, EV chargers, and heat pumps to your installed base?
If you’re not fully leveraging your customer relationships, it may be time to implement an automated engagement strategy that transforms your untapped goldmine into a dynamic engine for growth.
