The 5 keys to the sequence
3 emails, 1 phone call, 1 LinkedIn message — over 28 days.
Why this sequence works
1,025 prospects were contacted, with a response rate of 47% and 19 interested prospects. This campaign targets building owners in German-speaking Switzerland with a solar energy proposal requiring no upfront investment — a selling point that removes the financial barrier.
Including the prospect’s exact building address in the first email (Touch #2) demonstrates an impressive level of research. The prospect immediately realises that the message is not a generic one — someone has taken the time to identify their specific building.
The combination of “Best-case scenario: you cut costs. Worst-case scenario: you get a free benchmark” eliminates the perceived risk. For a property owner, this phrasing transforms taking a risk into an opportunity with no downside.
What you can learn from this campaign
- Customise with the building address. Mentioning the prospect’s exact address demonstrates impressive research skills.
- Remove the financial barrier. "No upfront investment" makes the offer a risk-free opportunity.
- Request a free impact assessment. A bespoke building assessment adds value even without a conversion.
- Combining self-consumption with roof leasing. Two business models to cater for all types of property owners.

Frequently Asked Questions
How can you sell solar panels without any initial investment?
The phrase "Best-case scenario: you cut costs. Worst-case scenario: you get a free benchmark" eliminates any perceived risk. The property owner has nothing to lose. The building’s exact address in the email proves that the offer is genuine and personalised. The free impact report adds value even if there is no conversion.
Why include the building address?
This is the clearest indication that the message is not generic. The property owner can immediately see that someone has identified their specific building. This research takes time but generates a response rate of 47% — well above that of generic solar campaigns (5–10%).
How can this lesson plan be adapted for the French-speaking market?
Translate the emails into French and adapt the legal references (Energiewende → energy transition, federal subsidies). The structure (LinkedIn + email + call to action) remains the same. Client references should be local to maximise credibility (Swiss care homes, for example).
