What is a Balcony Power Plant? The Complete Guide for Beginners

More and more households in Germany are becoming interested in renewable energies. However, not everyone owns a house with roof space for a large photovoltaic system. This is where the balcony power plant comes in.

A balcony power plant is a small, plug-and-play solar system specifically designed for apartments, balconies, or terraces. With such a system, tenants or apartment owners can generate their own electricity and simultaneously reduce their electricity costs.

The vision behind it: Energy transition in private hands

By now, the balcony power plant has become a self-evident term for all of us – we owe this progress primarily to Mr. Holger Laudeley, who, as a pioneer, first launched this groundbreaking idea. Today, the balcony power plant stands for renewable energy for every citizen and is a central building block of the energy transition in private hands.

More than 20 years ago, entrepreneur and engineer Holger Laudeley first presented this forward-looking vision to the public. Since then, he has tenaciously campaigned against energy companies, skeptics, and politicians who lack the necessary visionary foresight. His commitment is bearing fruit: the balcony power plant has enjoyed growing popularity for years, and the original vision is now a reality.

How does a balcony power plant work? A simple explanation

How does a balcony power plant actually work? A balcony power plant consists of a few, but important components:

• Solar modules: Convert sunlight into direct current.

• Micro-inverter: The heart of the system. It converts direct current into household alternating current.

• Mounting system: Holds the modules securely on the railing or terrace.

• Connection cable: Connects the system directly to your home grid via a standard socket.

The principle: The generated electricity flows via the socket directly to your household appliances such as the refrigerator, router, or washing machine. This automatically reduces the amount of expensive electricity you draw from the public grid.

How many kWh does an 800-watt balcony power plant provide?

How much electricity can a balcony power plant generate per day? Electricity production depends on orientation and solar radiation. A typical 800-watt system in Germany generates on average:

• 600 to 900 kWh per year.

• On sunny summer days, this is about 3 to 5 kWh per day.

This can cover a significant portion of the daily base consumption (standby devices, Wi-Fi, refrigeration units).

When does a balcony power plant pay for itself?

Is the purchase financially worthwhile? With costs between €500 and €1,500 and an electricity price of about 30–40 cents per kWh, you save approximately €150 to €300 annually. This means:

• Many systems have already paid for themselves after 3 to 6 years.

• Since high-quality modules last over 20 years, you will then produce completely free electricity for over a decade.

Does a balcony power plant require approval?

Can you simply install a balcony power plant? Thanks to the German government's Solar Package I, use is now very simple:

1. Registration: You only need to briefly register the system in the Market Master Data Register. Notification to the grid operator is no longer necessary.

2. Tenancy law: Tenants now have a legal right to a balcony power plant. Landlords may only prohibit installation in rare exceptional cases.

3. Meter: Old electricity meters may temporarily run backward until the grid operator installs a modern meter.

What does a storage unit do for a balcony power plant?

What is a balcony power plant with storage? A battery storage system is the ideal addition to significantly increase the self-consumption of solar power. It stores the electricity that you do not consume during the day (e.g., when you are at work) so that you can use it in the evening or at night.

Our recommendation for maximum efficiency:

Are you looking for a truly powerful system? Then we highly recommend the innovative complete storage systems SunEnergyXT 500 and SunEnergyXT 500 PRO.

In the following video, we present these novel all-in-one solutions with durable LFP batteries and integrated inverters. Featuring Holger Laudeley, the inventor of the balcony power plant, and Chengyuan Zhai, CEO of SunEnergyXT. Together, they explain the technology in detail and demonstrate how easily one can become energetically independent today.

Which balcony power plant is the best?

What should you look for when buying? When buying, pay attention to the following criteria:

• Module power: 800 watts is the current standard for feed-in.

• Durability: Choose quality modules with a long lifespan.

• Expandability: A system that offers the option for a battery storage (like the SunEnergyXT series) is the smarter long-term investment.

• Safety: Pay attention to certified inverters and stable mounting systems.

Conclusion: Is a balcony power plant a good idea?

A balcony power plant is the easiest entry into your own energy transition. It is cost-effective, uncomplicated, and, thanks to the pioneering work of individuals like Holger Laudeley, it is now a technical standard. Anyone who wants to reduce their electricity bill and protect the climate at the same time will find the ideal solution here.
