In principle, anyone can operate a solar system on the balcony. However, apartment owners and tenants need approval from property management if the solar system affects the overall appearance of the house, i.e. if it is visible from the outside.
To ensure that the registration is not mistaken and that the connection is correctly installed, an electrician must always be commissioned to commission the solar system with inverter. After all, such a solar system generates electricity, which poses dangers if misused. In addition, the specialist can really connect the system to the electricity meter in such a way that it works more slowly when the household appliances are powered by solar energy. Because nothing is more annoying than having your own solar system with an inverter, which brings no savings or even incurs fines because it has not been properly registered. And if the device is damaged due to improper installation, the costs are even higher.
