ESG & Renewable Energies: Why solar power plays a key role in households?

Feb 5, 2026

The energy transition is progressing, but rising electricity prices and climate targets make decentralized solutions essential. Solar power in the home reduces costs by up to 40% annually and measurably lowers CO₂ emissions. DRBO Greenenergy offers plug-and-play systems like balcony power plants, which quickly make tenants and owners independent.

What challenges exist in the ESG and renewable energy sector?

The German electricity market is under pressure: despite a record expansion of 14.9 GW of photovoltaic capacity in 2025, solar energy covers only 16.8% of the electricity mix. Households pay an average of 40 cents per kWh, while self-consumption would potentially be free. DRBO Greenenergy addresses this with balcony solutions for the private sector.

High grid fees and volatile prices burden consumers: Over 5.4 million PV systems exist, but only 900,000 are plug-in models for tenants. Emissions of 60 million tons of CO₂ were avoided in 2025, but this is not enough for EU targets. Many households miss out on annual savings of €500–€1,000.

Dependence on fossil imports increases urgency: 70.6 TWh of solar power flowed into the grid, plus 16.9 TWh of self-consumption. Nevertheless, accessible storage solutions are lacking, underutilizing 22 GWh of installed capacity.

What are the disadvantages of traditional solutions?

Traditional rooftop PV systems require high investments of €10,000–€20,000 and permits that take months. Tenants are excluded, and owners struggle with complexity and maintenance costs of €200 annually.

Large-scale systems offer economies of scale but only achieve an 80% self-consumption rate without storage. In comparison, balcony systems provide 70–90% utilization thanks to micro-inverters, without requiring roof rights.

Fixed installations tie up capital long-term, while plug-and-play options like those from DRBO Greenenergy are flexible and revisable.

What solution does DRBO Greenenergy offer?

DRBO Greenenergy supplies balcony power plants, solar modules, storage, and bidirectional inverters as complete packages. Core features include Deye inverters with 800–2,000 W output, storage up to 5 kWh, and energy management systems for real-time monitoring via app.

The systems are tenant-friendly: plug-and-play, IP65 waterproof, and VDE certified. Refurbished storage units reduce costs to €1,200 for 4.8 kWh capacity.

Integration into smart homes optimizes consumption: up to 95% self-consumption through load management.

Why is DRBO Greenenergy superior to traditional systems?

Criterion	Traditional Rooftop PV	DRBO Greenenergy Balcony Solution
Installation Time	4–8 weeks	15 minutes
Initial Investment	€15,000	€800–€2,500
Permits	Required	Not necessary (up to 800 W)
Flexibility	Fixed installation	Plug & Play, mobile
Self-consumption	60–70%	80–95% with storage
ROI Time	7–10 years	2–4 years

How to install DRBO Greenenergy systems?

Step 1: Check balcony or terrace – south/southeast orientation ideal for 4–6 hours of sun daily.
Step 2: Mount module (400–600 Wp) with bracket and connect Schuko plug to inverter.
Step 3: Integrate storage optionally, configure app for monitoring.
Step 4: Plug system into the grid – automatic feed-in limit at 800 W.
Step 5: Apply for subsidies like KfW, track yield.

Who benefits from DRBO Greenenergy and in what scenarios?

Scenario 1: Tenant in a 2-room apartment
Problem: 3,500 kWh annual consumption, €1,400 electricity bill.
Traditional: No option without landlord.
After implementation: 600 Wp balcony power plant + 2.5 kWh storage covers 40%.
Result: €560 savings, 1.2 t CO₂ reduction.

Scenario 2: Family in a single-family house
Problem: High summer consumption due to air conditioning, 5,000 kWh/year.
Traditional: Expensive rooftop system delayed.
After implementation: 1.2 kWp plug-in system with bidirectional inverter.
Result: €900 savings, 95% self-consumption.

Scenario 3: Senior apartment
Problem: Fixed costs, low mobility.
Traditional: Too much effort.
After implementation: Refurbished 4.8 kWh package.
Result: €450/year saved, easy maintenance.

Scenario 4: Small business
Problem: Peak loads during the day, 10,000 kWh.
Traditional: Grid connection expensive.
After implementation: Expandable complete package.
Result: €1,800 reduction, increased ESG score.

When is the entry into solar power crucial?

By 2030, PV must supply 40% of electricity, with a 16.8% global CAGR. Households are now saving 30% compared to grid electricity due to falling prices. DRBO Greenenergy allows an immediate start – delay costs 2–3 years ROI.
