Solar Installers Face Stricter Rules and Liability Risks After German Court Ruling
Published on 07/07/2026 at 05:54 | Redaktion boerse-global.de
The Koblenz Higher Regional Court (OLG Koblenz) has ruled that setting up turnkey photovoltaic systems qualifies as a regulated trade requiring a master craftsman certificate (Meisterbrief). The decision, handed down on 2 June 2026 (case reference 9 U 1015/25), applies to both roofers and electrical technicians. Even rooftop systems mounted with roof hooks need to be registered in the official skilled trades register.
The ruling settles a long-disputed area. Many solar companies had pushed for a relaxation of the master craftsman requirement, but the court made clear that no loophole exists. If a firm advertises an "in-house team" without using subcontractors, it must actually employ the necessary qualifications internally – regardless of how simple the work may appear.
As electrical standards grow stricter, fire safety compliance becomes even more critical – especially with new Power over Ethernet installations that demand integrated fire-protection concepts.

Liability for responsible electrical personnel intensifies
Parallel to the tightening of qualification rules, courts are sharpening their focus on the legal exposure of designated responsible electrical personnel (VEFK). These individuals answer not only for the technical execution of projects but also for supervisory tasks: selecting staff, giving clear instructions, and monitoring employees. Overlooking a single protective conductor contact can trigger civil damages claims or criminal consequences.
Liability depends on the degree of fault. In cases of slight negligence, workers often escape personal liability. But under medium or gross negligence, employers can seek recourse against them.
Construction-site electrical standards remain strict
The German Social Accident Insurance’s information sheet DGUV 203-006 continues to serve as the central technical guideline for electrical installations on construction sites. Although not a direct legal norm, it codifies the state of the art. Special caution applies to residual current devices (RCDs):
- Type A for simple appliances
- Type F for single-phase frequency converters
- Type B or B+ mandatory for three-phase systems up to 63 amperes
Testing intervals are rigid: fixed installations annually, RCDs monthly, and portable equipment on construction sites every three months. Operators also bear responsibility for any tools brought in by external contractors.
Skilled-worker shortage drives demand for hybrid expertise
Demand for highly qualified personnel shows no sign of easing. In early July, 166 new master craftsmen completed their training in electrical engineering and information technology in Lower Austria alone.

Emerging standards such as Power over Ethernet (PoE++ per IEEE 802.3bt) – which delivers up to 90 watts per port – demand specialised knowledge for accurate site surveys and integrated fire-protection concepts. Continuous training is also mandatory for safety systems like call systems in hospitals, which must comply with DIN VDE 0834-1 regarding self-monitoring and backup power supply.
Companies are increasingly hunting for electricians and engineers who combine technical skill with VDE knowledge and experience in fault analysis. Masters of the electrical trade with that profile are more sought after than ever.
