Balcony-based power plants surpass the one million mark - Balcony count surges, now standing at one million.
Get ready to soak up some sun – and savings! The number of balcony solar systems in Germany has skyrocketed, reaching a whopping 1 million. That's according to data from the Market Data Register and estimates by the German Solar Association (BSW).
Affectionately known as balcony power plants, these small solar installations can be mounted on – you guessed it – balconies, but they're not confined to that space. Each system can generate up to 800 watts of power when the sun's shining, reducing the strain on households' power suppliers.
This solar-powered savings accounts for the bulk of the installation's financial return. Extra power generated? That gets fed into the network at no cost. But systems with built-in storage units? Those follow different rules.
Wondering if it's worth the investment? Verivox, a comparison portal, crunches the numbers. Their analysis indicates it pays for itself within 2.5 to 5 years, especially when your balcony faces south, the modules are at a slight angle, and they stay out of the shade.
Now, let's dive into the details:
Numbers and Future Prospects
As of now (that's Tuesday!), the Market Data Register shows 975,583 installations up and running. Around 20,000 are on a temporary or permanent hiatus. The Federal Network Agency points out that the numbers on the register typically trail behind the actual number of balcony power plants due to a one-month reporting deadline and some unreported installations.
The half-million mark was reached in June 2024, so we've doubled that number in just over a year!
In a Verivox survey, 9% of respondents already had a balcony power plant, while 17% intend to snap one up. Approximately 21% don't have enough space, and 15% think it's not worth the investment. 19% of the 1,007 participants are against the idea of a balcony power plant.
Regulations and Impact on Inner Cities
Ever since the old traffic light coalition introduced regulations to simplify balcony power plant usage, their popularity has soared, particularly following the high electricity prices caused by the Ukraine conflict.
As solar roofs become more common in single-family homes, balcony power plants are increasingly shaping the solar landscape of inner cities. By allowing people to contribute to the energy transition directly, these mini-solar installations offer a way for a broader range of population groups to tap into renewable energy.
But here's the kicker – while there are around 1 million balcony power plants in operation nationwide, they only account for approximately 0.9 gigawatts of energy generation. Compare that to all solar installations across Germany, which include rooftops, open space, and more, and we're talking about a hundred times that amount.
State-Level Data and Impact
While we won't bore you with every state's figures, the major players include North Rhine-Westphalia (194,077 installations) and Bavaria (148,284 registrations). Both states likely have even higher actual numbers. Lower Saxony trails closely behind with 127,879 registered plants in operation, followed by Baden-Württemberg (127,665).
As we mentioned earlier, the density of balcony power plants tends to be lower in city-states due to fewer suitable locations for installation. So, don't be surprised if you see more solar panels gracing the balconies of buildings the next time you stroll through an inner city!

- As the use of balcony power plants continues to evolve, there's potential for an expansion in renewable-energy employment opportunities within the solar industry, given the increasing demand for both installation and maintenance services.
- The booming balcony solar systems market in Germany presents a unique chance for finance institutions to invest in the renewable-energy sector, offering tantalizing prospects for sustainable energy ventures and, in turn, promoting financial growth within the industry.
- With technology developments focusing on increasing energy efficiency and capacity alongside reducing costs, the potential for greater improvements in balcony power plants could lead to significant advancements in energy generation within the urban environment, fostering a transition towards a more eco-friendly industry and inner city landscape.
