The 5 biggest mistakes when installing photovoltaic systems – and how to avoid them

The demand for photovoltaic systems is growing rapidly. For installation companies, this means more orders, but also more responsibility. Installation errors can reduce efficiency or even cause damage. Here are the 5 most common mistakes – and how to avoid them:

1. Use unsuitable mounting systems
Cheap systems save money in the short term, but often lead to instability. High-quality aluminum profiles, on the other hand, ensure a durable, secure, and standards-compliant fastening.

2. Missing structural analysis
Wind and snow loads must be taken into account. Incorrect sizing jeopardizes the safety of the PV system.

3. Improper fastening to the roof
Drilling holes without sealing can lead to leaks. Appropriate mounting accessories prevent consequential damage.

4. Defective cable installation
Loose cables can be damaged. Cable channels and brackets are mandatory.

5. No documentation
Clear documentation facilitates maintenance and later expansions.

Conclusion:
Using the right aluminum photovoltaic mounting systems helps avoid mistakes and allows projects to be implemented efficiently and safely.
