How does a balcony power plant work optimally for tenants in Düsseldorf?

Feb 5, 2026

In Germany, electricity prices are continuously rising as the energy transition progresses. A balcony power plant offers tenants in Düsseldorf a straightforward way to generate up to 800 watts of solar power themselves and save 300 to 500 euros annually. DRBO Greenenergy provides plug-and-play solutions with high efficiency and easy installation, specifically tailored for tenants.

What is the current status of solar energy for tenants in Germany?

The energy transition is accelerating, but many tenants are excluded from large photovoltaic systems. According to the Federal Network Agency, over 500,000 balcony power plants were registered in 2025, an increase of 40 percent compared to 2024. Nevertheless, balcony power plants only cover 1-2 percent of private electricity demand, even though the need for decentralized energy is growing.

Electricity prices reached a peak of 39 cents per kWh in 2025, costing households over 1,200 euros annually. In Düsseldorf, with 1,550 hours of sunshine per year, the potential yield for an 800-watt system is up to 785 kWh. Despite this, 70 percent of tenants hesitate due to bureaucratic hurdles.

Reliance on grid electricity creates a financial burden, especially with rising prices. Many tenants miss out on savings of 200 to 400 euros annually because they do not use their own systems.

What problems does a balcony power plant solve that traditional methods do not?

Traditional solar systems require roof installation and high investments starting from 10,000 euros. They only pay for themselves after 8-12 years and are off-limits for tenants. Furthermore, landlord approval is often missing.

Large systems require electricians and grid operator approval, which takes months. Self-consumption is only 30 percent; the rest is compensated – at 8 cents/kWh, hardly profitable.

Tenants remain dependent on expensive grid electricity without flexibility. Plug-and-play alternatives, such as those from DRBO Greenenergy, completely circumvent these disadvantages.

What makes DRBO Greenenergy's solution so special?

DRBO Greenenergy offers balcony power plants with up to 2,000 watts of module power and 800 watts of feed-in, including Deye inverters and storage. The systems are ready-to-use, with mounting brackets and energy management systems for maximum efficiency.

The solutions maximize self-consumption to 70-80 percent through bidirectional inverters. In Düsseldorf, they generate 600-785 kWh annually, at costs of 400-800 euros.

DRBO Greenenergy supports tenants with complete packages that are VDE-certified and offer a lifespan of 20 years. The local team in Germany provides consultation and fast delivery.
