A website in three languages to sell solar energy to German clients in Mallorca
Greentech Balear installs solar panels, heat pumps and air conditioning in Mallorca. Its clients speak German, English or Spanish. Its website had to speak all three.
In shortThe three key points of this case
The client wanted a website of their own in three languages, with a clear offer for each service and a quote form that worked; the previous one was run by a third party.
Prototype before build. Two proposals in January and February, with video on the home page and the services as cards.
The website went live between May and July 2025. From May to December 2025 it collected 69 requests: 60 for quotes and 9 for repairs.
An international client base and a website that didn't speak its language
Greentech works for residents and second-home owners on the island. Many search in German; others in English. The previous website was run by a third party.
The client wanted a website of their own: in three languages, with a clear offer for each service and a quote form that worked. They signed off the full plan in January 2025.
Three languages, one structure
Prototype before build. Two proposals in January and February, with video on the home page and the services as cards. Then, the website.
- Eight services, three languages — solar panels, air conditioning, heat pumps, pool heat pumps, heating, ventilation, maintenance and emergencies, each with its own page in German, English and Spanish.
- Forms that work — quotes and repairs in each language, with spam protection and a notification to the client's inbox.
- Trilingual blog — grants, self-consumption and air conditioning, to show up in informational searches too.
- Measurement from day one — Search Console, Analytics 4 and a monthly report.
Quote requests that arrive in German
The website went live between May and July 2025. From May to December 2025 it collected 69 requests: 60 for quotes and 9 for repairs. Almost half were for solar panels.
A year later, clicks from Google have doubled (+101%) and organic sessions are up 95%. Germany brings in one in every three clicks.
