Balcony power plants are small photovoltaic systems, usually consisting of two modules and an inverter, that can be installed very easily. That is why they are often referred to as “Plug&Play”. However, the power of such a plant must not exceed 799 W (inverter power).

How does it work?

The balcony power plant generates electricity from its solar modules and feeds it directly into the home’s electrical grid via a standard electrical outlet. The electricity generated can then be consumed directly in the home. The surplus is fed into the public electricity grid but is not remunerated.

What do I need to pay attention to?

Modules must be CE certified. A “Wieland” plug (a special socket with outwardly isolated contacts) is recommended for safety reasons. Electrical installation must comply with current safety standards. A differential circuit breaker must be installed in the circuit. To ensure that modules placed outside are not torn off in the event of a storm, and to avoid any risk of injury, they must be sufficiently fixed or screwed in place.

Is a balcony power plant profitable?

A balcony power plant can reduce your electricity costs. It is more profitable if you manage to consume the electricity it generates yourself. You can check in advance, for example on your electricity supplier’s customer portal whether your electricity base load is sufficient to consume the electricity generated.

Can I also benefit from subsidies for a balcony power plant?

To qualify for the Klimabonus, the installation of the balcony power plant must be carried out by a professional. The financial aid can amount up to 62.5% of the costs (excluding VAT), with a maximum of 1,562.5 €/kWp if the offer is signed between January 1^st, 2023 and December 31^st, 2023. The application form must be signed by the professional who installed the system!
