Balcony power plant or photovoltaic system?
Which is the better choice for me?
The main difference between balcony power plants and photovoltaic systems is their size and efficiency.
Balcony power plants are usually small, decentralized photovoltaic systems installed on balconies or building facades. Their output is usually in the range of a few hundred watts to a few kilowatts. They use the same basic mode of operation as PV systems: sunlight is converted into electricity by the solar cells and fed into the power grid.
In contrast, PV systems can be both small and large, ranging from a few kilowatts to several megawatts. They are often installed on the roofs of buildings, open spaces or special solar parks. They also use the same mode of operation as balcony solar systems, but with a higher capacity.
Is a balcony power plant or a PV system suitable for me?
The consideration of whether the installation of a photovoltaic system or a balcony power plant is worthwhile depends on individual needs, the available budget, space and the legal framework:
Balcony power plant
Tenants and owners: worthwhile investment in the absence of roof access.
Quick savings on electricity costs with mini PV system on the balcony.
Contribution to the energy transition through the use of environmentally friendly electricity.
Mobility: easy disassembly and reassembly when moving.
Profitability in 2.5 years, depending on solar radiation, consumption and electricity prices.
Annual cost savings by profitability point.
PV plant
Own property: PV systems are long-term investments and contribute to the energy transition.
Reduction of CO2 emissions and fossil fuel dependence through the use of solar energy.
Financial investment with long-term return opportunities.
Differences in energy generation and feed-in
Balcony power plants: The energy generated is normally consumeddirectly on site . Surplus energy can be fed directly into the local power grid via the socket, provided that the appropriate legal framework and technical possibilities are available. However, an extra plug connection is required for the mini PV system so that the power output can withstand the additional load.
PV systems: The energy generated can be used on site, and surplus energy can be fed into the public power grid .
Differences in installation and location
Balcony power plants
They are designed for use on balconies or facades of buildings and usually do not require complex installation.
PV plant
Depending on the size and application, these are installed on roofs, open spaces or in special solar power plants. The installation can be more complex and often requires specialized professionals.
