A balcony power plant, also known as a mini solar system or plug-in solar system , is a small, plug-in PV system consisting of 1–4 modules, a microinverter, and a mounting bracket that converts sunlight into electricity. It can be installed in a particularly space-saving manner on a balcony, facade, terrace, garage, or pitched roof, and is particularly suitable for renters or homeowners for whom a large solar system is not an option.

Yes, you can install a balcony power plant in addition to a rooftop system and thus further optimize your self-consumption. However, this will require an additional inverter that operates independently for the BKW. The systems cannot be operated via an inverter; they must be installed separately.

No, not usually. However, registration with the market data register and the network operator is mandatory. Tenants should inform their landlord – in most cases, installation cannot be prohibited without a valid reason.

Those who are rarely home during the day can feed the excess power from their mini-PV system into the public grid – a contribution to the energy transition, but also wasted electricity. The solution: a balcony power plant with storage . This way, solar energy is stored during the day and used in the evening when the sun isn't shining. The electricity flows directly from the storage into the home grid instead of the public grid. Without storage (link), you use the solar power directly. With storage, you can store excess energy and use it later – increasing your independence.

Ferraris meters with backflow preventers, modern digital meters, and smart meters are permitted for mini-PV systems.

The solar module converts sunlight into direct current. The inverter generates standard household alternating current, which is fed directly into the home's electrical system via a standard electrical outlet.

Our sets arrive securely packaged by a freight forwarder or parcel service – including assembly instructions and, if requested, mounting materials.

Most balcony power plants have a feed-in power of 600 to 800 watts. The right size for you depends on your electricity consumption and the available space (e.g., balcony, flat roof, garden).

Yes, a balcony power station is connected via a standard Schuko socket or, optionally, a Wieland socket. It is important that the installation is carried out professionally and that the socket complies with current safety standards.

No. Installing a mini-PV system is easy and can be done without a specialist. It is connected via a standard Schuko socket. Alternatively, the balcony power station can be connected to the house's electrical system via a Wieland socket or a fixed connection . Important: Both options require installation by a qualified electrician.

Prices vary depending on size and optional storage. You can get the most affordable balcony power plant from us for under €400. Subsidies in many German states can further reduce the purchase price.

Many cities and federal states offer subsidies for mini-PV systems and plug-in solar systems. Furthermore, the 19% VAT on balcony solar systems and accessories is waived. Suppliers bill the products directly tax-free.

Many federal states and cities offer their own subsidies; the amount and conditions vary.

Tip: Check regional funding programs before purchasing, as requirements vary.

The correct orientation of the balcony power plant is crucial for high yields: A south-facing orientation is ideal, where the sun shines vertically and for a long time. Those who consume more electricity in the morning benefit from a (south-)east orientation, while those who consume more electricity in the evening benefit from a (south-)west orientation. The angle of inclination is also important: In Germany, 30–40 degrees is optimal.

It depends on the installation location: There are special mounting brackets for lattice balconies, and racks with the right tilt angle for flat roofs. At Solarkontor, you'll find sets with and without brackets, tailored to your needs.
