SellsMounting systems for large solar projects: flat and green roofs, trapezoidal metal roofs, solar carports and ground-mounted plants, for installers, EPCs and project developers
PeriodSep 24 – Nov 4
Ideal client: decision-makers who buy or build commercial solar: EPCs, installers and project developers, property owners and real estate managers, CEOs of mid-size companies with roofs and parking lots, and municipalities.The challenge: The CEO posts almost every day about the energy transition: records, policy, climate and the company's own projects. The policy posts get the biggest reach. Which posts reach the people who buy solar carports and C&I systems?
These numbers are from 4 November. Your audience has already moved.

1 in 4 readers is a decision-maker.317 CEOs, managing directors, owners, heads of department, buyers and project developers reacted between 24 September and 4 November: 24.4% of the 1,300 people we read.
Project posts bring 1.5x the share of policy posts.Projects and the solar industry (sites, real estate, a new market): 30.0% decision-makers. Energy policy (quotes, the demo, subsidies): 19.7%.
23 decision-makers came back 3 times or more.4 of them reacted to 5 posts or more, and one of them to 6 of the 22.

Who actually reads you, and what the LinkedIn algorithm changed
The CEO posted 22 times between 24 September and 4 November, in German and once in Italian: solar records, energy policy, climate news, and the company's own sites and projects.
The LinkedIn algorithm shows a post first to the people closest to the author, then to people like them. For a solar CEO with 36,000 followers, that first circle is the energy transition community: activists, engineers, colleagues and other solar companies. Reach can't tell them apart from the people who buy. Who reacted can. We read the first 100 reactors on each post and sorted them by role.

The 231 peers include the company's own team, sales and marketing people at other solar companies, students and researchers. They give each post its first push, and they don't sign orders.
The 317 decision-makers are the readers that matter: CEOs of installers and EPCs, managing directors of solar and storage companies, heads of large-project sales, buyers, project developers, real estate managers and owners of mid-size companies outside the energy sector. The 752 others are mostly engaged citizens and engineers who share the mission: they spread the posts, but they rarely buy a carport.

6 rules for LinkedIn engagement from decision-makers
These rules come from what worked on the CEO's own profile, and from the best-performing German posts on solar and the energy transition on LinkedIn over the last 3 months.
1
Show the site, not the slide. Steel, aluminium, modules and the people who build them. A named project, its size and who was there beats a statement about the energy transition. Decision-makers react to proof they can picture.On this profile: the post on ten days of sites and customer visits (5 MW in Lübeck) reached 33% decision-makers, the public building in Münster 31%.
Speak the owner's language: value and running costs. Property owners and CFOs don't buy CO₂ savings first. They buy lower running costs and a building that keeps its value. Put roofs and parking lots in those terms.On this profile: "Lage, Lage, Lage. Sondern: Energie." reached 35.1%, the highest share of the 22 posts.
Make one number tangible. 90.2 TWh means little. 775,000 tanker trucks means a lot. Translate one figure into something a buyer can see: trucks, kilometres, euros on the electricity bill.Across the niche: a post turning 24 kWp on a truck tarp into 18,000 km and up to €22,250 saved drew 340 likes and 211 comments.
End with a clear invitation to the people you want. "If you develop, plan or build large C&I or utility plants: let's talk." Naming who should get in touch filters the readers for you and turns a post into a conversation.On this profile: the Italian market post, which ends on that line, reached 34.6% decision-makers.
Keep policy for reach, and say what it means for the customer. Policy posts travel furthest in the niche, but they pull in activists and peers. When you post about the EEG or the grid, add one line on what it changes for a company with a roof or a parking lot.On this profile: energy policy posts reached 19.7% decision-makers, against 30.0% for projects. Across the niche: the Berlin demo post drew 2,312 likes.
Give the customer's reason, not yours. The climate is the mission. A lower electricity bill, a charged fleet and a safe roof are the reasons to buy. Lead with the reason that matters to the buyer.Across the niche: Octopus Energy Germany's CEO opened with "a lower electricity bill is a perfectly good reason" and drew 197 likes and 24 comments.

5 posts ready to publish to target decision-makers
Each post follows the rules above, in the CEO's voice and in German. Check the facts, the sites and the customer names with the team before posting: the real project is what makes them land.

Gestern stand ich auf einem Firmenparkplatz. 180 Stellplätze. Bisher hat er genau eins gemacht: Autos abgestellt.In ein paar Monaten steht dort ein Solarcarport.Und wenn man mit dem Geschäftsführer über das Projekt spricht, geht es erstaunlich wenig um CO₂. Es geht um drei Fragen:→ Was kostet uns der Strom in fünf Jahren?
→ Wie laden wir die Flotte, ohne den Netzanschluss zu sprengen?
→ Was ist die Immobilie wert, wenn sie ihre Energie selbst erzeugt?Genau das ist der Punkt, den ich auf jeder Messe und jeder Baustelle höre: Ein Parkplatz ist Fläche, die bisher nur Geld kostet. Mit einem Carport darüber wird er Teil der Energieversorgung des Unternehmens.Schatten im Sommer, trockene Autos im Winter, Ladepunkte darunter, Strom für die Halle nebenan.Die Energiewende baut man nicht vom Schreibtisch aus. Und auch nicht nur auf dem Dach.Wer einen großen Parkplatz hat und wissen will, was darauf möglich ist: Schreiben Sie mir eine DM. Ich schaue es mir gerne mit Ihnen an.

Lage, Lage, Energie: what a stranded asset costsRules 2 and 3: the owner's language and one number made tangible. Modelled on the EXPO REAL post, the highest share of decision-makers on the profile (35.1%).

Ein Gebäude ohne Energiekonzept ist kein Sanierungsfall. Es ist ein Bewertungsfall.Auf der EXPO REAL habe ich darüber gesprochen, und die Gespräche danach haben mich in einem Punkt bestätigt: Viele Eigentümer schauen noch auf die Lage. Die Käufer und Mieter von morgen schauen auf die Energie.Ein paar Zahlen:→ Rund 60 % der 19,8 Millionen Wohngebäude in Deutschland wurden vor 1977 gebaut.
→ Rund 56 % werden mit Gas beheizt, weitere 17 % mit Öl.
→ Gebäude stehen für rund 35 % unseres gesamten Endenergieverbrauchs.Wer heute nichts tut, hat morgen ein Stranded Asset. Steigende Energiekosten, höhere Anforderungen, ein Wert, der nach unten geht.Dabei liegt die Lösung oft direkt auf und neben dem Gebäude: Dächer für Photovoltaik, Parkplätze für Carports, Speicher, Wärmepumpe, Ladepunkte.Das sind keine grünen Add-ons mehr. Das ist die Wertstrategie einer Immobilie.An alle Eigentümer, Asset Manager und Facility Manager hier: Wo hakt es bei Ihnen am meisten, bei der Finanzierung, beim Netzanschluss oder bei der Fläche?

114.8% on a good day, 28.4% on a bad oneRules 3 and 5: one figure made tangible, then what it changes for a company. Modelled on the 114.8% post (33.3%) and the solar record post (30.3%).

114,8 % an einem Tag im Oktober. 28,4 % am 6. Januar. Beide Zahlen gehören zur Energiewende.Am 24. Oktober haben wir in Deutschland mehr erneuerbaren Strom erzeugt, als wir verbraucht haben. An zehn Tagen in diesem Jahr lagen wir über 100 %.Und an anderen Tagen eben nur bei einem Viertel.Für Unternehmen steckt in diesem Unterschied die eigentliche Chance:→ Wer eigenen Solarstrom erzeugt, kauft an guten Tagen fast nichts zu.
→ Wer einen Speicher hat, nimmt den Mittag mit in den Abend.
→ Wer flexibel lädt oder heizt, nutzt die Stunden, in denen Strom am günstigsten ist.Der Batteriespeicherzubau legte in den ersten neun Monaten 2026 um 91 % zu. Das sind nicht nur Netzbetreiber. Das sind Gewerbebetriebe, Logistiker, Kommunen.Der Rekord ist schön. Aber gewinnen wird, wer aus Überschuss ein Geschäftsmodell macht.Wie nutzen Sie in Ihrem Betrieb die Mittagsspitze heute schon?

7 questions to ask any PV offerRule 6 and the lead magnet: the buyer's fear (safety, cheap offers), then a resource. Modelled on the "Geiz ist geil" post (30%) and Thomas Tergan's checklist post (169 comments).

Das günstigste PV-Angebot ist nicht das Problem. Das Problem ist, dass man es nicht vergleichen kann.Vor ein paar Wochen habe ich über die Sicherheit von Solaranlagen geschrieben. Die Versicherungsdaten zeigen eine niedrige Schadenhäufigkeit. Aber wenn bei der Vergabe nur der Preis entscheidet, geraten Planung, Montage und Prüfung unter Druck.Danach haben mich viele gefragt: Worauf sollen wir als Unternehmen konkret achten?Hier sind 7 Fragen, die ich jedem Angebot für ein Gewerbedach oder einen Carport stellen würde:1. Ist die Statik für dieses Dach geprüft, oder angenommen?
2. Welches Montagesystem wird verwendet, und ist es für Dachart und Windzone zugelassen?
3. Wer plant die Lastverteilung, und wird sie dokumentiert?
4. Wie wird der Brandschutz berücksichtigt, inklusive Abstände und Zugänge?
5. Welche Leistungen sind enthalten, welche kommen später dazu?
6. Wie wird die Montage abgenommen und geprüft?
7. Wer ist in 10 Jahren Ihr Ansprechpartner?Ein hoher Preis garantiert keine gute Anlage. Ein niedriger Preis ist noch kein Mangel. Aber wer diese 7 Fragen nicht beantworten kann, sollte nicht den Zuschlag bekommen.Ich habe daraus eine einseitige Checkliste gemacht. Wer sie haben möchte: Kommentieren Sie „CHECK“, und ich schicke sie Ihnen.
Visual · Single imageThe checklist itself: the 7 questions with a tick box each, the PMT logo small at the bottom.Check before postingKeep "Danach haben mich viele gefragt" only if people really asked; otherwise start with "Worauf sollten Unternehmen konkret achten?". Have the technical team check the 7 questions. Put your Netwarm Reveal link on the checklist so you can see which decision-makers open it.
A charging park needs a roofRules 4 and 6: the customer's reason and a clear invitation. Modelled on the "Netzfund der Woche" post (589 reactions, ending on truck carports) and Nanno Janssen's charging park post.
Hook
Zehn Ladesäulen mit je 300 kW. Und darüber: nichts als Himmel.So sehen heute viele Ladeparks für E-Lkw aus. Und ich verstehe es: Erst muss die Flotte fahren, dann kommt der Rest.Aber wer einmal durchrechnet, sieht schnell, warum das Dach dazugehört:→ Der Netzanschluss ist teuer und knapp. Eigener Solarstrom und ein Speicher entlasten ihn genau dann, wenn alle Fahrzeuge laden.
→ Jede Kilowattstunde vom eigenen Carport muss nicht teuer eingekauft werden.
→ Fahrer und Fahrzeuge stehen im Trockenen, die Technik im Schatten.Die Logistiker, die heute schon auf E-Lkw setzen, denken ihren Standort als Energiesystem: Lkw, Ladepunkte, Photovoltaik, Speicher, Energiemanagement.Genau dafür bauen wir Carportlösungen, auch für Trucks.Wenn Sie einen Ladepark planen oder schon betreiben: Schreiben Sie mir. Ich zeige Ihnen gerne, was über Ihren Ladesäulen möglich ist.

LinkedIn lead generation: lead magnets that work to target decision-makers
A reaction tells you someone read the post. A download tells you they want to act on it. For a solar company, a decision-maker who asks for a checklist on PV offers is already comparing suppliers.
These formats work in German-speaking LinkedIn right now. Each one is backed by a real post that offered it.
Format 1The checklistOne page, a list of things to check, offered at the end of a post that names a fear. Property owners and facility managers keep it and pass it on.
Format 2The ready-to-use templateSomething the reader can use the same day: a calculation sheet, a prompt, a template. Offered for a comment, it drives comments, and comments carry the post further.
Format 3The industry briefingA short regular summary of the market for people who decide: new rules, deals, prices. "Write briefing in the comments" builds a list of readers who want more.
Our pick: the PV offer check for commercial roofs and carports
Our pick for you: “Our pick: the PV offer check for commercial roofs and carports”The CEO already wrote the post that sets it up: the "Geiz ist geil" post on PV safety and cheap offers reached 30% decision-makers. Turn its last part into a one-page checklist of 7 questions to ask any offer (draft 4), and offer it for a comment.

From reactions to clients
Most decision-makers never comment. They read, react, and come back. In 6 weeks, 23 of them reacted to 3 posts or more, and 4 to 5 posts or more.
A decision-maker turns Hot when they react to several posts in a short time: a sign they are thinking about a project now. That is the moment to send a message, about their roof, their parking lot or their fleet, not about the post.

How we made this playbook
Period: 24 September to 4 November 2026, 22 posts (one post of 5 November left out). We read the first 100 reactors on each post: 1,613 reactions from 1,300 people. Comments were not counted.
Decision-makers are classified from their LinkedIn headline (CEO, managing director, owner, founder, director, head, buyer, project developer, real estate and facility roles); the company's own team and sales, marketing, student, teaching and research roles count as peers. Role groups are approximate.
Niche rules and lead magnets come from the best-performing German LinkedIn posts on solar and the energy transition over the last 90 days.
