Electrician
Over 20 years of experience in electrical installation — ensuring every connection is safe and compliant.
Before offering it to our customers, I wanted to go through the process myself. In September 2027, LetzSolar installed my own solar panels in Reckange-sur-Mess — our very first project. From the Klimabonus application to commissioning, I went through exactly the same journey you will.
