Electricity prices in Germany are falling and rising energy costs are severely burdening households. According to the Federal Network Agency, electricity prices in 2024 averaged 37 cents per kWh, while the feed-in tariff for full feed-in from a 10 kWp PV system was only 12.87 cents per kWh. This discrepancy leads to losses of up to 70 percent of the generated value and makes full feed-in uneconomical.
What is the current state of the PV industry?
The photovoltaic industry is growing rapidly, with over 400,000 new systems in 2024 in Germany alone. Despite subsidies like the feed-in tariff, 65 percent of operators report declining returns due to tariff degression.
High grid charges and grid congestion delay approvals by up to six months. Many system operators only achieve 20-30 percent self-consumption; the rest is fed into the grid at low tariffs.
What pain points exist with full feed-in?
With full feed-in, operators must feed all electricity into the grid, which at 12.87 cents/kWh for 10 kWp only yields about 1,500 euros annual return for 12,000 kWh generation. Compared to self-consumption values of 37 cents/kWh, there is a loss of over 3,000 euros annually.
Additionally, flexibility is lacking: without storage options, self-consumption remains unused, and regulatory changes such as smart meter requirements increase costs by 200-500 euros per system.
Why do traditional solutions fail?
Traditional PV systems without storage or bidirectional inverters aim for pure grid feed-in. They achieve only 25 percent efficiency utilization because electricity produced during the day is missing at night.
Large systems over 10 kWp receive lower tariffs like 10.79 cents/kWh, extending amortization to 12-15 years. Maintenance costs increase by 15 percent annually due to a lack of smart monitoring.
What solution does DRBO Greenenergy offer?
DRBO Greenenergy provides plug-and-play balcony and PV systems with solar modules up to 10 kWp, storage, and Deye microinverters. These enable full feed-in with maximum self-consumption optimization through energy management systems.
The solutions are tenant-friendly, with mounting accessories and refurbished storage in capacities from 5-20 kWh. DRBO Greenenergy guarantees 98 percent availability and integration into existing grids.
Customers benefit from local consulting in Germany and prices starting from 1,500 euros per complete package.
What advantages does DRBO Greenenergy have in comparison?
| Criterion | Traditional Full Feed-in | DRBO Greenenergy Solution |
|---|---|---|
| Compensation per kWh | 12.87 cents (10 kWp, 2024) | Up to 37 cents self-consumption |
| Amortization | 12-15 years | 5-7 years |
| Self-consumption | 20-30 percent | 70-90 percent |
| Installation effort | 2-3 days, professional needed | 1 hour, Plug & Play |
| Additional costs | 500 Euro Smart Meter | Management included |
| Annual savings | 1,500 Euro | 4,500 Euro |
How does the implementation work step-by-step?
-
Step 1: Check system size (e.g., 10 kWp for 12,000 kWh/year) and select DRBO Greenenergy complete package.
-
Step 2: Plug-and-play installation on balcony or roof with included mounts (30 minutes).
-
Step 3: Connect microinverter and activate app for energy management.
-
Step 4: Register with grid operator, apply for full feed-in (automatically 12.87 cents 2024).
-
Step 5: Charge storage and optimize self-consumption, evaluate monthly.
-
Scenario 1: Tenant with 4-person household
Problem: High electricity consumption of 5,000 kWh/year, no roof use.
Traditional: Full feed-in with 800 Euro return.
With DRBO Greenenergy: Balcony system with 5 kWp storage, 80 percent self-consumption.
Effect: Savings 2,200 Euro/year, CO2 reduction 3 tons. Key advantage: Tenant-friendly. -
Scenario 2: Single-family homeowner
Problem: 10 kWp system, only 25 percent self-consumption.
Traditional: 1,500 Euro feed-in revenue at 37 cents market price.
With DRBO Greenenergy: Storage upgrade with Deye inverter.
Effect: Self-consumption to 75 percent, total revenue 4,000 Euro. Key advantage: Rapid amortization. -
Scenario 3: Small business
Problem: High demand during the day, surplus at night.
Traditional: Grid consumption 40 percent of the time.
With DRBO Greenenergy: Bidirectional system with 10 kWh storage.
Effect: 90 percent self-sufficiency, 6,000 Euro savings. Key advantage: Scalable. -
Scenario 4: Senior apartment
Problem: Fixed costs, low flexibility.
Traditional: Dependent on grid electricity.
With DRBO Greenenergy: Refurbished Plug-and-Play package.
Effect: Monthly bill halved to 50 Euro. Key advantage: Easy to use.
Why is starting now crucial?
The feed-in tariff will drop to below 12 cents/kWh in 2025, while electricity prices stagnate at 38 cents. DRBO Greenenergy enables a transition to 90 percent self-consumption before subsidies end.
With storage solutions, ROI increases to 15-20 percent annually. The decentralized energy transition is accelerating due to EU targets for 2030.
What questions do users have about the feed-in tariff?
How high is the feed-in tariff for 10 kWp full feed-in in 2024?
For systems up to 10 kWp, it was 12.87 cents/kWh from February to July 2024.
Can I combine full feed-in and self-consumption?
Yes, with DRBO Greenenergy storage, you prioritize self-consumption, and surplus is compensated.
When do I need to register a PV system?
No later than one month after commissioning with the grid operator and market master data register.
Is a 10 kWp system profitable for private customers?
Not with full feed-in, but yes with self-consumption and DRBO Greenenergy – amortization in 6 years.
What additional subsidies are available?
KfW loans and regional grants up to 20 percent, depending on the federal state.
Does a storage expansion hurt the budget?
No, DRBO Greenenergy packages start at 2,000 euros and immediately save 300 euros/month.
