A photovoltaic system is only as good as the installation behind it. At T&R Solutions GMBH, we handle the complete PV system installation for commercial and industrial clients across Germany, from initial planning and system design through to on-site installation and final commissioning.
With over 12 years of hands-on PV installation experience and completed projects across retail, logistics and industrial facilities, we know what a properly installed system looks like and what it takes to deliver one. Every installation is planned to suit the specific site and carried out by a team that understands the full scope of the work.



We visit the site, assess roof structure, orientation, shading and load capacity before any system design or procurement begins.
Custom PV system design based on the site assessment, covering panel layout, inverter selection, wiring routes and grid connection requirements.
Professional mounting of PV panels on commercial and industrial rooftops using correct fixing systems for each specific roof type.
Full inverter installation and DC and AC wiring carried out to standard, connecting the panel array to the building grid connection point.
Coordination and installation of the grid connection for the PV system, handled in line with German network operator requirements.
Full system commissioning, output testing and handover carried out on completion so the client receives a fully operational PV installation.
We visit the site, review requirements and plan the full scope of work before anything begins.
Our team prepares a detailed installation plan covering materials, timelines and all technical specifications for the job.
We execute the installation to spec, carry out final checks and hand over the completed project on schedule.
