Common mistakes in photovoltaic installation

After you have purchased a photovoltaic system, you can continue with the photovoltaic installation. The technical know-how for professional photovoltaic installation is provided by solar installers, but also roofers and electrical engineers. It is best to use a company that already has experience with photovoltaic installation. This way you can ensure that you avoid the most common mistakes.

The roof hooks are badly mounted

Roof hooks are often poorly installed, especially on rooftop installations. Here, the specialist must insert the solar modules with the help of U-shaped hooks. The aim of these photovoltaic roof hooks is to distribute the total weight of the PV system and to relieve the roof. If the installation is poor, the pressure can increase and become problematic, especially with older roof trusses. This can lead to a leaking roof, dampness in the attic and consequential damage.

Do not consider the peculiarities of the roof

For the PV system to function properly, it must be installed precisely. To make this possible, the installer will walk on your roof and check for unevenness. Especially with older roof trusses, individual parts can become deformed due to the effects of the weather. If this is the case with your roof, the expert must take precautions so that the solar modules can function properly.

Poorly laid wiring

The solar cables must be carefully attached to the modules or the substructure. Otherwise, they can move and, in the worst case, be damaged. In the best case, the constant movement creates unpleasant noises that are nonetheless stressful for the residents. In addition, it is necessary to comply with fire protection regulations - a task for the expert.

The wrong material

To make your solar system a faithful companion, you need the right materials for photovoltaic mounting. This applies to all components that are necessary for mounting the solar modules. Ideally, you should always choose the products that the manufacturer recommends. In this particular area, the electrician should not start tinkering or use particularly cheap solutions - the individual elements must above all be securely connected.
