Definition: What is a balcony power plant?
Protect the climate and produce your own green electricity – with a balcony power plant, anyone with a balcony or terrace can generate energy. Balcony power plants are also known as plug-in mini-PV systems, plug-in solar systems, plug & play solar systems, or mini solar systems. These small solar systems typically consist of one or two solar panels and supply electricity directly to the household grid through a wall outlet.
The electricity generated is usually consumed at home and not sold, given the limited output. Another benefit is cost savings: using your own generated electricity lowers your electricity bills.
How does a balcony power plant work?
The operation of a plug-in solar system or Balcony Solar Battery is straightforward. When sunlight hits the solar panel, it converts solar energy into direct current. An inverter then transforms the direct current into alternating current, which feeds into the household power grid through a standard power outlet.
To operate according to safety standards, a special energy plug-in device is required.

What are the individual components of a balcony solar power plant?
A Balcony Solar Battery plant usually includes four main components: PV module, inverter, plug, and assembly. Optionally, operators can add an electricity meter or upgrade the system with a battery storage unit. Users may also choose complete Balcony Solar Battery solutions that include both components and professional installation.
Balcony power plant PV module
The photovoltaic module is the most crucial component of a mini-PV system. Users can choose high-quality monocrystalline panels for higher efficiency and energy yield, or more affordable polycrystalline panels.
Inverter for mini PV system
The inverter converts the direct current produced by the solar panel into alternating current suitable for home use.
Cable and plug for power supply
The plug and socket may vary depending on the system. For compliant operation, mini solar power systems require a special power outlet and plug.
Experts confirm that these systems are safe, provided the inverter includes a protection device that automatically shuts off in case of grid or connection issues. This protection is standard in many inverters.
Solar power system balcony mounting
To maximize electricity yield, users should mount panels in optimal locations. Angled stands can hold panels but occupy balcony space. Alternatively, external brackets preserve floor space.
Balcony solar system monitoring
Monitoring usually involves an electricity meter. While optional, it allows users to track energy production, calculate annual savings, and estimate payback periods. The meter installs between the inverter and the outlet.
Balcony power plant with electricity storage
Since most balcony power plants serve self-consumption only, excess electricity may go unused. Adding a battery storage unit allows users to store surplus energy and use it when needed. However, storage solutions are relatively expensive.
Maximum wattage of a balcony power plant
The maximum allowable wattage depends on the conductor cross-section of the existing supply line and the current capacity of the plug and socket.
What does a balcony power plant cost?
At first glance, the cost of a plug-in solar system seems high and may only pay off after several years. However, the investment also brings environmental benefits, as it reduces reliance on fossil fuels. A Balcony Solar Battery is portable, making it suitable for tenants who may move residences.
