How do balcony power plants with storage work?

Article published at: Dec 8, 2025

Balcony power plants with integrated energy storage generate solar power that is either used directly or stored in a battery. Surplus energy is automatically temporarily stored and fed into the house grid when needed. This creates independence from grid power. Plug-and-play solutions, such as those from DRBO Greenenergy, enable easy use and simplify the integration of solar energy into everyday life.

What is a balcony power plant with storage?

A balcony power plant with storage is a compact solar system that generates electricity and stores it in a battery. Solar modules convert sunlight into direct current, which is either used immediately in the household or stored in a battery for later. These systems increase self-consumption and enhance energy self-sufficiency. DRBO Greenenergy offers powerful SunLit storage options that are seamlessly integrated and are ideal for both tenants and homeowners. The intelligent control ensures that every ray of sunshine is optimally utilized and the generated electricity is efficiently used in the household.

How does a balcony power plant with storage work?

A balcony power plant with storage works by solar modules generating direct current during the day, which is either consumed directly or stored in a battery. The micro-inverter converts the stored direct current into alternating current when needed and feeds it into the house grid. An intelligent energy management system ensures that energy is used as efficiently as possible. DRBO Greenenergy uses bidirectional inverters that ensure surplus electricity is not lost but stored for later use.

Component Function Benefit
Solar modules Generate electricity from sunlight High yield even in diffuse light
Battery (e.g. SunLit) Store surplus Use stored electricity even at night
Micro-inverter Convert DC to AC Direct feed into the house grid
Energy management Automatic prioritization Highest efficiency in electricity use

What components does a balcony power plant with storage need?

A balcony power plant with storage consists of several important components: solar modules, a micro-inverter, a battery storage unit, and various cables and mounts. The solar modules capture sunlight, the inverter converts the generated direct current into alternating current, and the battery stores surplus electricity for later use. DRBO Greenenergy offers complete sets that contain all necessary components and are easy to install. These include SunLit storage solutions, known for their high efficiency and longevity.

What are the advantages of balcony power plants with storage?

Balcony power plants with storage offer numerous advantages: they increase self-consumption of solar power by up to 100%, allowing households to significantly reduce their electricity costs. They also contribute to independence from the power grid, as they can supply stored energy even with little sunshine or at night. CO2 emissions are reduced and the environment is protected. Thanks to the possibility of using subsidies and government grants, the systems usually pay for themselves within 3-5 years. DRBO Greenenergy ensures that installation and use remain uncomplicated and are also easily possible for tenants.

Advantage Without storage With storage
Self-consumption 30-40% 70-100%
Amortization 5-7 years 3-5 years
Availability During the day 24/7
Savings/year €100-€300 €300-€600

How to install a balcony power plant with storage?

Installing a balcony power plant with storage is simple and involves a few steps: First, the solar modules are mounted on a bracket and connected to the micro-inverter and the battery. The entire wiring is plugged into a Schuko socket. Registration with the grid operator is required, but even here, the effort is minimal. DRBO Greenenergy offers plug-and-play solutions that do not require electrical installation and are ready for operation in a short time. The installation process usually takes 30 minutes.

Why is a balcony power plant with storage worthwhile?

A balcony power plant with storage is particularly worthwhile because of the long-term cost savings. Households can significantly reduce their electricity costs by using their own solar power and drawing less electricity from the grid. With an ROI of less than 3 years with rising electricity prices, the system becomes increasingly attractive. In addition, the value of the property can increase with the installation of a balcony power plant. Subsidies such as KfW or regional grants make entry into solar energy particularly affordable.

Which storage unit to choose for balcony power plants?

The choice of the right storage unit depends on the size of the household and individual electricity consumption. For singles, a storage unit with a capacity of 1 kWh is often sufficient, while families need a storage unit with 3 kWh or more. DRBO Greenenergy offers SunLit storage options with a capacity of 2-10 kWh, which are expandable. The choice of LiFePO4 batteries offers high safety and a long service life, as these batteries can withstand up to 6000 charging cycles.

What are the costs for balcony power plants with storage?

The costs for a balcony power plant with storage vary depending on the size and capacity of the system. The entry price for an 800-watt system with a 1-kWh storage unit is between 800 and 1500 euros. Extensions cost approximately 500 euros per kWh. These costs usually pay for themselves within 3-5 years through savings on electricity bills. DRBO Greenenergy also offers attractive complete sets at fair prices.

How to maximize the yield of a balcony power plant with storage?

To maximize the yield of a balcony power plant with storage, the system should be optimally aligned. A southern orientation with a 30° tilt is ideal. Regular cleaning of the solar modules and the use of apps for consumption control also contribute to increasing efficiency. DRBO Greenenergy offers an app that supports users in optimizing energy generation and use.

Conclusion: Key Points and Next Steps
