Booming Balcony Solar Power Storage Market: A Look at the Latest Offerings and Trends
The market for balcony solar power storage systems is experiencing a significant surge, particularly in Germany where over one million balcony solar installations are now operational as of June 2025, more than doubling from 500,000 in June 2024 [1]. These systems are contributing significantly to new solar capacity additions, with about 53 MW installed in April 2025 alone [3].
One of the latest offerings in this space is a set with four bifacial XL modules from Jolywood, totalling 2000 watts, combined with a storage block (2.048 kWh), available at Solakon for 1,049.99 Euro [2].
In terms of pricing, basic balcony solar kits like those recently introduced by IKEA in Germany cost around $500 for a package including two 450-watt solar modules [4]. However, adding battery storage systems such as the Growatt NOAH 2000 or Marstek B2500-D increases the cost due to their battery inverter technology. While specific pricing details for these storage-equipped systems were not directly available, market trends indicate an increasing adoption of such storage solutions driven by government simplifications, rising electricity prices, and supportive policies [1][2].
The Growatt NOAH 2000 is a popular residential energy storage system with around 2 kWh usable capacity designed to pair with solar installations for self-consumption and backup power. The Marstek B2500-D is a 2.5 kWh home energy storage system geared toward integration with small solar setups.
Interestingly, the Growatt NOAH 2000 battery storage system now offers zero feed-in, allowing for greater self-consumption. The storage system is available from specialist retailer ACTEC for 1,050 Euro, including a 2.048 kWh Growatt NOAH storage for balcony solar, 4x 500 Watt Trina Vertex S+ Blackframe double-glass modules, 1x Growatt NEO 800X-M microinverter, various cables, and a Solakon app for monitoring [2].
The Marstek B2500-D, on the other hand, offers an extremely low price of 399 euros for 2.24 kWh, making it about 70 euros cheaper than the Growatt NOAH 2000 in terms of price per kWh of storage capacity [2].
For those seeking more affordable options, mini-PVs with up to 800 watts are not subject to permit requirements. The market for mini solar systems is competitive, with systems now available for under 300 euros.
In the UK, the government is also moving to unlock plug-and-play balcony solar markets by conducting safety reviews aimed at enabling users to install small socket-connected solar power systems easily and safely, which should further expand accessibility and market growth in coming years [2].
Moreover, the dynamic electricity tariff from Tibber allows users to pay the current wholesale electricity price (excluding taxes and levies). The monthly basic fee is 5.99 Euro. Balcony power plants are becoming increasingly popular for decentralized household energy supply.
It's important to note that mini-PVs are not subject to permit requirements for systems up to 800 watts. The Growatt NOAH 2000 battery storage system uses a LiFePO4 battery designed for over 6000 charge cycles, making it a reliable solution for expanding balcony power plants without significant technical expertise. The system is protected against dust and heavy rain, making it suitable for outdoor use.
In conclusion, the market for balcony solar power storage systems is growing rapidly, with a range of affordable and efficient solutions available. Whether you're looking for a comprehensive system like the Quattro-Set with the Growatt energy storage system from ACTEC, or a more budget-friendly option, there's a solution to suit your needs. With government support, competitive pricing, and the potential for significant energy savings, it's no wonder that balcony power plants are becoming increasingly popular for decentralized household energy supply.
