What makes DRBO Greenenergy's Solar + Storage Upgrade Set the ideal solution for private energy transition projects?

The Solar + Storage Upgrade Set from DRBO Greenenergy revolutionizes private solar systems by seamlessly expanding existing balcony power plants. With two 380 Wp SunLit solar modules and a 2.15 kWh storage unit, it maximizes yield and self-consumption, reduces costs by up to 70%, and promotes independence from rising electricity prices. DRBO Greenenergy provides a practical plug-and-play solution for tenants and homeowners.

What are the challenges in the solar energy industry?

In Germany, electricity prices rose by 12.5% in 2025 to an average of 40 cents per kWh, while the solar share of the electricity mix reached only 14%. According to the Federal Network Agency, this causes an additional cost of 50 billion euros annually for households, as fossil fuels continue to dominate. Private users miss out on up to 60% of their solar yield due to a lack of storage.

The energy transition is stalling: over 80% of private solar systems without storage achieve less than 30% self-consumption, as a study by Fraunhofer ISE shows. Grid bottlenecks in urban areas exacerbate the problem, with failures of up to 10% of the feed-in. DRBO Greenenergy addresses this with scalable solutions.

Households pay 100–150 euros too much monthly, as energy produced during the day has to be repurchased expensively at night. Climate targets for 2030 require 15 GW of additional decentralized storage capacity, but only 2 GW have been installed. The urgency is growing due to EU requirements and volatile energy imports.

Why do traditional solutions fail?

Traditional balcony power plants without storage only achieve 25–35% self-consumption, as surplus flows into the grid – often compensated at less than 8 cents/kWh. Separate storage installations cost 1,500–3,000 euros plus electrician fees, with payback periods exceeding 10 years. Many tenants fail due to bureaucratic approvals.

Large-scale rooftop systems require an investment of 5,000–10,000 euros and are unsuitable for balconies. Cheap no-name products have 20–30% failure rates, without app integration or warranty. In comparison, the Solar + Storage Upgrade Set from DRBO Greenenergy achieves 70–90% self-consumption for 949 euros.

What does the Solar + Storage Upgrade Set from DRBO Greenenergy offer?

The set includes two 380 Wp SunLit solar modules (760 Wp total output) and a 2.15 kWh SunLit BK215 storage unit with a Deye inverter. It extends existing systems plug-and-play, with modular expandability up to 8.6 kWh. The SunLit App enables remote control and prioritization of self-supply.

High-quality components ensure 95% efficiency and a 10-year warranty. Compatible with microinverters such as APSystems or Hoymiles, it fits 90% of balcony power plants. DRBO Greenenergy ensures fast delivery and local support in Germany.

What are the advantages of the Upgrade Set in comparison?

How to install the Upgrade Set step-by-step?

• Step 1: Switch off existing balcony power plant and check modules (5 min.).

• Step 2: Mount two SunLit modules with the supplied brackets and connect them in parallel (15 min.).

• Step 3: Connect the storage unit to the inverter via Schuko plug (5 min.).

• Step 4: Download the SunLit App, pair WiFi, and activate self-consumption mode (10 min.).

• Step 5: Start the system and track yield – no registration required up to 800 W.

Who benefits in typical scenarios?

Scenario 1: Tenant with an 800 W balcony power plant
Problem: 60% solar power fed into the grid, monthly repurchase of 80 euros. Traditionally: Cheaper storage without modules, 40% loss. After upgrade: 85% self-consumption, 50 euros/month savings. Key gain: 600 kWh/year stored, CO2 savings 300 kg.

Scenario 2: Family in a terraced house
Problem: High evening consumption, 120 euro bill. Traditionally: Rooftop system too expensive (€5,000). After upgrade: Storage covers 70% of night electricity, amortization in 4 years. Key gain: 1,500 kWh/year self-generated electricity, 900 euro savings.

Scenario 3: Senior apartment
Problem: Little sun in the evening, 50 euro additional costs. Traditionally: No expansion possible. After upgrade: App prioritizes hot water, 80% usage. Key gain: Stable supply, 400 kWh/year extra.

Scenario 4: Small business (office)
Problem: Surplus during the day, night surcharges. Traditionally: Grid feedback uneconomical. After upgrade: 90% self-consumption, 200 euros/month saved. Key gain: Scalable to 8.6 kWh, ROI under 3 years.

Why is it crucial to get started now?

By 2030, private storage must grow to 20 GW to ensure grid stability – subsidies like KfW are decreasing. Rising prices (forecasted +15% in 2026) make upgrades urgent. DRBO Greenenergy is positioned as a reliable partner with a 4.6/5 Trustpilot rating. Those who invest now save in the long term and contribute to the energy transition.
