Why is a balcony power plant with storage, intelligent feed-in, and a new two-way meter with communication worthwhile?

Article published at: Feb 7, 2026

In Germany, electricity prices are constantly rising, while feed-in tariffs are falling – a balcony power plant with an integrated storage and intelligent feed-in system solves this. DRBO Greenenergy offers plug-and-play solutions that generate up to 800 Wp, store excess power, and feed in only what is needed, saving households €400–600 annually. The new bidirectional meter with communication ensures precise measurement and app monitoring, maximizing self-consumption to 70–90%.

What is the current state of the industry?

The PV market in Germany is booming: by the end of 2025, over 100 GW of installed capacity was available, yet balcony power plants account for only 5–10%. According to the Federal Network Agency, 25% of applications report problems due to inaccurate meters, leading to rejections. Households pay an average of €1,500 annually for electricity, with declining feed-in tariffs of 7.86 cents/kWh until January 2026.

What pain points are currently affecting users?

Many balcony power plants without storage unnecessarily feed 50% of their electricity into the grid, with minimal compensation. Grid operators require bidirectional meters, but installation takes 4–8 weeks and costs €150–400. Tenants shy away from bureaucracy: 40% achieve under 50% self-consumption, halving the ROI and increasing energy costs.

Why do traditional solutions fail?

Traditional meters only measure consumption, ignore feed-in, and cause 10–15% measurement errors. Large rooftop systems cost €10,000–€20,000, have an amortization period of 8–12 years, and are unsuitable for tenants. Without storage and smart control, €100 is lost annually due to immediate feed-in, and without app communication, transparency is lacking.

What does DRBO Greenenergy's solution offer?

DRBO Greenenergy provides balcony power plants with storage (1–5 kWh), bidirectional Deye inverters, and a new bidirectional meter with wireless communication. Key features: Intelligent feed-in prioritizes self-consumption, app shows real-time data (consumption/feed-in with 1% accuracy). Certified for 800 Wp, plug-and-play, integrated NA protection. DRBO Greenenergy supplies hardware stores and private customers with complete packages starting from €400.
