Our Story
At One Terawatt peak, we have been committed to helping consumers realize the full potential of their roofs and harness renewable energy since 2009.
In 2009 we founded a company with a vision. We wanted to make the world a better place - better solutions for solar and - a better service. We dared to take the first step. Despite limited resources, we were motivated to work hard and improve constantly. Even today we are still particularly proud of our success and remain innovative.
A year after founding our company, we achieved a significant milestone in developing an innovative and practical software. Our dedicated team worked tirelessly to exceed customer expectations. Countless hours of research, design, and testing resulted in the creation of a game-changing solar cadastre for Germany.
The first step abroad! In 2012 we expanded our cadastre offer with the Netherlands and were thus able to reach more customers and fulfill their wishes.
In order to further expand our offer, we have introduced a pilot project in Poland to also be able to offer our service here.
After our first steps in the Netherlands in 2012, we completed them in 2014. We have also included Denmark in our portfolio and started a pilot project in France.
The UK joins our data as a pilot project. We have also founded the Dutch joint venture "ZONATLAS NL B.V." in order to be able to help our customers even better with our service.
In 2016, our transformative partnership with Google provided invaluable data, resources, and support, elevating our work, fostering innovation, and creating a fruitful relationship that contributed to the success of both companies. We are grateful for this opportunity and its significance in our achievements.

Spain and Luxembourg join our open data countries. Welcome to the family!
Our data is growing! In 2021 we added Austria to our available cadastre-data!
After Austria, our neighbour Switzerland also joined our data for solar cadastre!
We are thrilled to fill the map! In the future we want to work on including the whole of Europe and beyond in our cadastral pool.
