How do homeowners properly combine solar and storage?

The energy transition is progressing, yet many homeowners miss out on up to 40 percent of their generated solar power due to a lack of compatibility. DRBO Greenenergy offers practical complete solutions with solar modules, storage systems, and energy management systems that increase self-consumption to over 80 percent and shorten payback periods to under 6 years.

What challenges currently exist in the solar industry?

In Germany, over 500,000 new photovoltaic systems were installed in 2025, but self-consumption is only 30 percent without storage. Rising electricity prices of around 0.40 Euro per kWh burden households with annual costs of up to 1,500 Euro.

Many systems generate surplus power during the day, which is fed into the grid and only yields 8 cents per kWh. Without storage, the potential is wasted, leading to unnecessary losses.

Homeowners struggle with unsuitable combinations: solar modules don't match storage systems, causing efficiency losses of 20-30 percent. DRBO Greenenergy addresses this with tested complete packages.

Why do traditional solutions fail for solar and storage?

Traditional solar systems without integrated storage achieve only 25-35 percent self-consumption, as surplus is lost in the evening. Separate retrofitting often requires an electrician and costs an extra 2,000-5,000 Euro.

Many older storage systems are not optimized for microinverters, causing charging losses of up to 15 percent. Plug-and-play alternatives are lacking, which complicates installations.

In comparison, DRBO Greenenergy solutions mitigate these problems with modular, compatible systems featuring Deye inverters and app control.

What makes the DRBO Greenenergy solution stand out?

DRBO Greenenergy provides complete packages with solar modules up to 380 Wp, storage systems from 3-10 kWh, and bidirectional inverters. Energy management systems automatically optimize charging cycles based on consumption and weather data.

The systems are IP65 weather-resistant and expandable, with real-time app monitoring. Plug-and-play design allows self-installation in under 2 hours, ideal for renters and homeowners.

DRBO Greenenergy relies on refurbished storage systems with full performance, reducing costs by 30 percent with a 10-year warranty.

What advantages does DRBO Greenenergy offer in comparison?

How to set up a DRBO Greenenergy system?

• Step 1: Connect solar modules to microinverter with MC4 cables (10 minutes).

• Step 2: Connect storage in parallel via plug-and-play and download the app (20 minutes).

• Step 3: Configure energy management system – enter consumption data, set charging times (15 minutes).

• Step 4: Mount modules (use balcony mounts), start system, and register with the grid (30 minutes).

• Step 5: Monitor app – first yields after 1 hour of sunshine.

Who benefits from DRBO Greenenergy in which scenarios?

Scenario 1: Tenant with balcony (family, 4 people)
Problem: High evening consumption, 800 kWh/month. Traditionally: 20% self-consumption.
After implementation: 2 kWp + 5 kWh storage, app optimizes charging.
Effect: 75% self-consumption, 450 €/year savings. Key benefit: Mobility, no drilling required.

Scenario 2: Single-family home (2 people, electric car)
Problem: 500 kWh/month, charging consumption in the evening. Traditionally: 70% grid dependency.
After implementation: 4 kWp + 8 kWh storage, bidirectional inverter.
Effect: 60% self-sufficiency, 600 €/year savings. Key benefit: Charging electric car with solar surplus.

Scenario 3: Senior household (1 person)
Problem: 300 kWh/month, low consumption, but high prices. Traditionally: Storage unused.
After implementation: 1.6 kWp + 3 kWh storage, simple app.
Effect: 80% self-consumption, 250 €/year saved. Key benefit: Maintenance-free, intuitive operation.

Scenario 4: Holiday home owner
Problem: Seasonal use, grid connection expensive. Traditionally: System unused.
After implementation: 3 kWp + 6 kWh storage, weather-resistant IP65.
Effect: 90% self-sufficiency, 400 €/year reduction. Key benefit: Offline function during outages.

Why is now the crucial time to enter solar-storage combinations?

By 2030, 15 million storage systems are to be installed; subsidies like KfW grants are decreasing. DRBO Greenenergy enables amortization in 5-7 years with rising grid tariffs.

Smart systems adapt to increasing e-car use and ensure independence. DRBO Greenenergy is driving the decentralized energy transition forward.

What questions do homeowners have about solar and storage?

How do I choose the right storage size?
Calculate your annual consumption divided by 365, multiplied by 1.5 for buffer – DRBO Greenenergy provides individual advice.

Can I use a system as a tenant?
Yes, plug-and-play balcony power plants with storage are mobile and permit-free up to 800 W.

How realistic are the savings?
For 5 kWp and 6 kWh storage: 500-800 €/year, depending on sun exposure and consumption.

Is an electrician required?
No, DRBO Greenenergy sets can be installed without screws, and grid registration is possible online.

How do I expand the system later?
Modular storage and modules can be connected in parallel, capacity up to 20 kWh.

What happens in a power outage?
Emergency power function supplies devices up to 2 kW, island mode integrated.
