Can garden photovoltaics accelerate the energy transition?

Jan 30, 2026

The energy transition is progressing, but many households remain excluded from clean solar energy. Garden photovoltaics offer a flexible solution for tenants and owners without roof space, with up to 800 Wp output and self-consumption of over 70 percent. DRBO Greenenergy makes these systems plug-and-play accessible, reduces electricity costs by up to 400 euros annually, and promotes independence through storage integration.

What challenges are there in the garden photovoltaic industry?

The German PV market is booming: by the end of 2024, 100 GWp were installed, with 16.9 GWp newly added. Nevertheless, there is a lack of solutions for gardens without a power connection, where 40 percent of households leave potential untapped. Rising energy costs of over 1,500 euros per year for a four-person household exacerbate the pressure.

Balcony and garden systems are growing, with 800,000 plug-in systems by 2024, but grid overload and falling feed-in tariffs to 7.86 cents/kWh by January 2026 reduce profitability. Many users only achieve 30-50 percent self-consumption, which means annual losses of 100 euros.

Tenants and garden owners struggle with bureaucratic hurdles and lack of mobility, while grid fees increase by 10 percent annually. Without storage solutions, surplus electricity dissipates, delaying the energy transition.

Why do traditional PV systems fail in the garden?

Traditional rooftop systems cost 10,000 to 20,000 euros for 5 kWp and require an electrician, amortization takes 8-12 years. They are tied to fixed locations and ignore gardens without a connection, with only 30 percent self-consumption.

Fixed installations lack bidirectional inverters and storage, losing 50 percent of their yield due to immediate feed-in. Impossible for tenants, as landlord approval takes weeks.

In the garden, they fail due to mobility: no plug-and-play, high transport costs, and no app monitoring. DRBO Greenenergy stands out with flexible garden systems.

What does DRBO Greenenergy offer as a garden photovoltaic solution?

DRBO Greenenergy supplies plug-and-play systems with solar modules up to 800 Wp, Deye micro-inverters, and storage from 1-5 kWh. These generate 800-1,000 kWh annually on 2 m², prioritize self-consumption, and store for evening loads.

Bidirectional inverters enable NA protection class integration without an electrician, with app monitoring. Complete packages including brackets and cables are certified for 20 years.

DRBO Greenenergy supplies hardware stores and private customers with refurbished storage at 90 percent of the new price, ideal for decentralized gardens.

What advantages does DRBO Greenenergy have over traditional systems?

Criterion	Traditional PV systems	DRBO Greenenergy Garden PV
Installation costs	€10,000–€20,000	€400–€1,200
Amortization period	8–12 years	3–4 years
Self-consumption rate	30–50%	60–80%
Installation	Specialist required	Plug & Play, 30 minutes
Mobility	Fixed installation	Relocatable in the garden
Storage integration	Optional, expensive	Integrated from €500

How to install garden photovoltaics step-by-step?

Step 1: Check area (min. 1.5 m² per module), choose south orientation for 90 percent yield.
Step 2: Select DRBO Greenenergy set with module, inverter, and plug.
Step 3: Mount modules with brackets, connect cables, plug into current limiter (max. 16 A).
Step 4: Register with network operator (online, confirmation in 2 weeks), apply for feed-in tariff.
Step 5: Install app for monitoring, optimize storage.
Step 6: Track yield, feed in surplus.

Who benefits in typical garden scenarios?

Scenario 1: Tenant with a small garden
Problem: High bill of €120 monthly, no connection.
Traditional: Buy grid electricity.
Effect: 600 kWh self-consumption, bill halved.
Gain: €400 savings, €50 tariff.

Scenario 2: Family home with terrace
Problem: Evening loads due to electric car.
Traditional: Expensive rooftop system.
Effect: 900 kWh yield, 70 percent evening storage.
Gain: 3 years amortization, 400 kg CO2 savings.

Scenario 3: Senior garden
Problem: Fixed pension, rising costs.
Traditional: No option.
Effect: 400 kWh covers basics.
Gain: €250 savings, easy maintenance.

Scenario 4: Small business
Problem: Daytime consumption, 35 cents/kWh.
Traditional: Commercial tariff.
Effect: 1,000 kWh self-consumption.
Gain: €350 savings, scalable.

Why is garden photovoltaics essential now?

By February 2026, the feed-in tariff will drop to 7.78 cents/kWh, storage trends will grow by 20 percent by 2027. DRBO Greenenergy secures 20-year funding, protects against price fluctuations, and promotes decentralization.
