Are you thinking about installing a balcony PV system to join the energy revolution and reduce your electricity costs? Or are you simply curious about the benefits, costs, and functionality of such a system? You’ve come to the right place! We’ve compiled answers to the most frequently asked questions, providing a comprehensive overview of balcony PV systems.
A balcony PV system is a compact solar energy setup mounted on a balcony, terrace, or the facade of a building. It's designed to be easily plugged into a socket, offering a decentralized form of energy generation. The electricity produced can be used on-site for your own consumption or fed back into the grid.
A balcony PV system uses photovoltaic (solar) modules to convert sunlight into electricity, initially in the form of direct current (DC). To make this electricity usable in your household, it must be converted into alternating current (AC), which is done by an inverter attached to the system. Once converted, the electricity can be used to power household electronics and, for homes with electric heating systems, to generate hot water and heating.
A balcony PV system helps generate renewable energy, enabling you to actively contribute to the energy transition. By reducing your reliance on grid electricity, it can also lead to significant savings on your energy costs—especially with the current high energy prices. Additionally, you can earn money by feeding any surplus electricity back into the public grid.

The amount of electricity a balcony PV system generates depends on its size. Typically, a small balcony solar system with an output of 200 to 600 watts can produce up to 500 kWh of electricity annually. To put this in perspective, the average annual electricity consumption for a 2-person household is around 2,500 kWh. However, this is an estimate, and the actual energy output of a balcony PV system can vary based on several factors, including the orientation and positioning of the balcony, the amount of sunlight, and the number of daily sunshine hours.
The size of a balcony PV system depends on the available space on your balcony or façade, as well as regulatory requirements, which we can help you understand. Before purchasing a system, it's important to measure the available area to ensure you choose the right size and number of solar panels for your needs.
Yes, a balcony PV system must be registered with the grid operator and included in the market master data register. Both steps are required before commissioning the system and can be done free of charge.
The typical lifespan of a balcony PV system is around 20 to 25 years, which primarily applies to the solar modules. However, conventional inverters, which convert direct current to alternating current, usually have a warranty period of 7 to 12 years.
A balcony PV system can typically be installed by yourself using the provided installation instructions. Since installation procedures may vary depending on the supplier and manufacturer, it’s important to follow the steps carefully and adhere strictly to the instructions if you choose to install the system on your own.
Yes, you can build a balcony PV system yourself. You’ll need detailed instructions, the right tools, and manual skills. If you're unsure about your ability to complete the installation, it's best to hire a professional company or consult qualified specialists for assistance.
Unfortunately, a balcony PV system typically doesn't generate enough energy to cover all of a household’s electricity needs. During early mornings and evenings when it's dark, you’ll still rely on electricity from the public grid. However, a balcony PV system can significantly reduce your electricity consumption from the grid, helping to lower your energy costs.
No, a balcony PV system doesn’t require special care. Regularly check the solar panels for dirt or damage, and clean or repair them as needed to ensure optimal performance.
