We’ve noticed that {{companyName}} may have high electricity consumption and available roof space. Have you ever considered using solar energy to reduce your electricity bills and benefit from stable prices? Many companies are now installing on-site solar power systems to reduce their costs—whether they invest in or manage the installation themselves—whilst supporting the energy transition. I thought this might also be of interest to {{companyName}}. --- → Message including colleagues’ names (sent 7 days later): Hello {{salutation}} {{lastName}}, is managing electricity costs or energy infrastructure part of your remit, or do you work with someone else on this?{% if colleaguename1 != blank and colleaguename2 != blank %} Perhaps {{colleaguename1}} or {{colleaguename2}}?{% elsif colleaguename1 != blank %} Perhaps {{colleaguename1}}?{% elsif colleaguename2 != blank %} Perhaps {{colleaguename2}}?{% endif %} --- → Follow-up message (sent 8 days later): {{salutation}} {{lastName}}, If reducing energy costs and securing long-term electricity prices are priorities for {{companyName}} in {{year}} and beyond, {{SalesRep}} and I would be delighted to show you how {{client_ref}} and others are achieving this without any upfront investment.

EmailDay 1Email #2
Subject: building / {{companyname}} in {{buildingcity}}
Version A (Example: care home) Dear {{salutation}} {{lastName}}, I noticed that {{companyName}} owns the building located at {{buildingaddress}}. Companies are working with us to reduce their electricity bills and avoid price spikes by installing solar power systems on their premises. There is no upfront cost, and you can continue to focus on your business whilst we take care of the rest. Would this be of interest to {{companyName}}? Or am I way off the mark? Best-case scenario: you reduce your costs. Worst-case scenario: you get a free comparative analysis. Kind regards, {{salesRep}} P.S.: One of our clients, a care home, reduced its overall energy bill by 15% with a self-consumption rate of 97%. And we paid a five-figure sum to another client simply to rent their roof. {{signature}} --- Dear {{salutation}} {{lastName}}, Would it be better to contact {% if colleaguename1 != blank %}{{colleaguename1}}{% endif %}{% if colleaguename1 != blank and colleaguename2 != blank %} {% endif %}{% if colleaguename2 != blank %}{{colleaguename2}}{% endif %}? {% if colleaguename1 == blank and colleaguename2 == blank %} Would it be better to contact someone else?{% endif %} In the meantime, here is a one-page document summarising how our customers have ultimately joined the Energiewende without having to go it alone. Please let me know what you think. Kind regards, {{signature}}

Email7 days laterEmail #4
Dear {{salutation}} {{lastName}}, I have just tried to call you on {{phonenumber}}. Several Swiss companies, such as {{companyName}}, have recently contacted us to find out how a rooftop solar installation could reduce energy costs or generate rental income by utilising unused roof space. We offer a free impact report tailored to your building, whether it involves savings through self-consumption or full feed-in with roof leasing. No investment or management is required. Would you be available for a brief 10- to 15-minute phone call to see if this is a good fit for {{companyName}}? Kind regards, {{signature}}
Email7 days laterEmail #5
Dear {{salutation}} {{lastName}}, I have contacted you several times and I wouldn’t want to keep bothering you if this isn’t a priority at the moment. Would it be possible to send you an update in a few months’ time? If it is simply a matter of timing, or if someone else at {{companyName}} is handling this matter, please let me know. Kind regards, {{signature}}

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).
