About us
Your partner for solar energy.
JT Solarbau GmbH is an owner-led specialist contractor for photovoltaic (PV) systems. We plan and install tailored solutions for residential and commercial clients across Germany and, depending on the project, internationally. We combine precise workmanship with the conviction that solar energy is a key step towards a more independent and sustainable future.
We build for the future
JT Solarbau GmbH delivers professional end-to-end PV solutions — from planning to installation. We have already planned and installed hundreds of PV systems.
Why do customers choose us? Because we take responsibility for the complete project: planning, documentation and coordination, installation, as well as optional inspections, service and monitoring — all from one source and with our own in-house team.
As the founders of JT Solarbau GmbH, we have been working with the economic use of solar energy for many years and can look back on numerous satisfied customers from the residential, commercial, agricultural and public sectors.
If you value reliable service, a dedicated point of contact, honest advice and solutions tailored to your needs — JT Solarbau is the right partner for your project.
We build for the future.
