The mini PV system has been delivered, the box opened, and anticipation is high. But then comes the crucial question: "How do I attach the balcony power plant securely so that it stays firmly in place even during the next autumn storm?" The good news is that, with a few simple tricks, installation is easier than expected. By following a few basic rules, the balcony power plant can be installed quickly, safely, and permanently – providing clean electricity right outside the balcony door.

Balcony power plants offer a practical way to cover a portion of electricity demand and reduce energy costs. The investment often pays off after just a few years.

But how do you install them? Many systems can be easily attached to railings with brackets. For wall or floor mounting, drilling, doweling, and screwing are required. Here, it is important to use the right fasteners, tailored to the substrate, weight, and size of the system, manufacturer's specifications, and wind and snow loads. For concrete, for example, bolt anchors such as the fischer FAZ II Plus made of stainless steel are suitable. Chemical solutions such as the fischer FIS V Plus or fischer FIS V Zero injection mortars are also the right choice. They provide high load-bearing capacity, low edge distances, and expansion pressure-free installation. Injection systems are also suitable for solid brick, perforated brick, and aerated concrete—a sieve sleeve, such as FIS H K, ensures even mortar distribution in perforated brick. In load-bearing wood, wood screws, such as fischer PowerFast II made of A2 or A4 stainless steel, are usually sufficient. Important for outdoor use: screws and steel components should be made of stainless steel.

In addition to secure mounting, professional electrical connection is also essential: only correctly connected balcony power plants avoid risks such as back voltage, fire, or electric shock.

Once everything is in place, it's time to soak up the sun, save electricity, and enjoy the DIY achievement. With careful planning and the right fasteners, the mini PV module becomes a permanent source of energy and reliably supplies solar power directly from the balcony.
