Balcony power plants

The energy transition is in full swing and more and more people are looking for ways to make their own contribution to sustainable energy production. A particularly simple and cost-effective solution that has gained popularity in recent years is so-called balcony power plants. These small solar systems offer a straightforward way to generate your own electricity and thus reduce electricity costs. In this article, you will learn everything you need to know about balcony power plants, their advantages and how you can install such a system in your own home.

What is a balcony power plant?

A balcony power plant is a mini photovoltaic system that is specially designed for use on balconies, terraces or house walls. It is a compact solar system that consists of one or more solar modules and an inverter. The inverter converts the direct current (DC) generated by the solar panels into alternating current (AC), which can be fed directly into the home grid.

These small solar systems are ideal for tenants or apartment owners who do not have space for a large photovoltaic system on the roof. A balcony power plant can be easily attached to a railing or wall and provides enough power to cover part of your own needs.

Advantages of balcony power plants

Balcony power plants offer numerous advantages that make them an attractive option for many people:

1. Easy installation: One of the biggest advantages of balcony power plants is their ease of installation. They do not require extensive construction work or permits, as is often the case with larger photovoltaic systems. Many systems are supplied as "plug-and-play" solutions that are easy to connect. You can simply plug it into a socket and the electricity generation starts.

2. Cost efficiency: Balcony power plants are very cost-effective compared to larger solar systems. The purchase costs are usually between 500 and 1500 euros, depending on the size and performance of the system. Since you generate some of your own electricity, you can reduce your electricity costs and the system usually pays for itself within a few years.

3. Sustainability: With a balcony power plant, you make an active contribution to reducing CO2 emissions. The electricity generated comes from a renewable energy source and reduces your dependence on fossil fuels.

4. Flexibility: Another advantage of balcony power plants is their flexibility. They are not tied to a fixed location and can easily be dismantled and reinstalled at the new place of residence if you move.

5. Independence: By generating your own electricity, you become more independent of rising electricity prices and energy suppliers. This can be a great advantage, especially in times of increasing uncertainty on the energy markets.

How does a balcony power plant work?

The way a balcony power plant works is extremely simple. As soon as the solar modules capture sunlight, they generate electrical power in the form of direct current (DC). This power is then converted by the inverter into alternating current (AC), which is suitable for operating household appliances. The power generated is fed directly into the house network and can be used immediately. Any excess power that you do not use is usually fed into the public power grid.

Most balcony power plants are equipped with a simple plug that is plugged into a normal household socket. As soon as the system is connected, it automatically starts producing electricity. No special technology or prior knowledge is required to operate a balcony power plant.

What should you look for when choosing a balcony power plant?

If you want to buy a balcony power plant, there are a few important factors you should consider:

1. Power: The power of a balcony power plant is given in watts (W). The higher the power, the more electricity the system can generate. Typical balcony power plants have an output between 300 and 600 watts. Consider how much power you need and choose a system that meets your needs.

2. Inverter: The inverter is a crucial component of your balcony power plant because it converts the direct current into usable alternating current. Make sure that the inverter works efficiently and fits the technical requirements of your apartment.

3. Installation and orientation: The balcony power plant should be installed in such a way that the solar modules capture as much sunlight as possible. Make sure it faces south and avoid casting shadows to ensure maximum electricity production.

4. Certification: Make sure that the balcony power plant meets all the necessary certifications and safety standards. In Germany, for example, all systems that feed electricity into the grid must meet the requirements of the VDE standard.

Legal framework and permits

In most cases, no special permit is required to install a balcony power plant. However, there are some legal frameworks that must be observed. In Germany, for example, balcony power plants must be registered with the grid operator if they feed electricity into the public grid. This is usually straightforward and can often be done online.

In addition, tenants should obtain the landlord's consent before installing a balcony power plant, especially if structural changes need to be made to the balcony or facade.

Conclusion

Balcony power plants are an excellent way to generate your own electricity cheaply and easily while contributing to the energy transition. They are particularly suitable for tenants and homeowners who do not have space for a large solar system. With easy installation, low costs and the option to take the system with you when you move, balcony power plants offer a flexible and sustainable solution for every household. If you want to reduce your energy costs and become more independent of rising electricity prices, a balcony power plant is a worthwhile investment.
