Bifacial modules are one of the increasingly widespread technologies in modern solar systems in Germany and Europe. However, their ability to convert sunlight into electricity on both the front and back of the module significantly increases the technical requirements for cable routing and installation on the back of the module.
Soiling can significantly impair the performance of your PV system. Even slight soiling leads to a loss of efficiency and can reduce the service life of the modules. Drainage clips offer a practical solution here.
The service life of a photovoltaic system depends not only on the quality of the solar modules, but also to a large extent on the mounting and connection materials used. Find out more here.

Reliable electrical connections are a key requirement for the safe operation of photovoltaic systems. Even the smallest contact faults can lead to increased contact resistance, heat generation or, in extreme cases, arcing in the long term.
Protective pipes in PV systems are often underestimated - yet they have a significant influence on service life and operational safety. Black is not a UV certificate: only long-term UV-stabilized pipes made of PP-UV, HDPE-UV or PVC-U with a documented test certificate are suitable for roof and outdoor applications. Separating application areas, choosing the right pressure class and planning for fire protection requirements reduces downtime and ensures system availability.
DC connectors that can be mechanically joined together are by no means safe to combine. Cross-installation - i.e. mixing connectors from different manufacturers - is one of the most common and most dangerous installation errors in photovoltaic systems. What appears to be a practical technical solution can result in a fire hazard, loss of warranty and personal liability. What electrical installers and PV specialist companies need to know - and how the risk can be reliably avoided.
Installation errors in photovoltaic systems are among the most common causes of damage and yield losses. The technical article explains typical sources of error and shows practical solutions.
