The choice between a simple balcony power plant and a system with storage depends on budget, electricity consumption, and the desire for self-sufficiency. A basic balcony power plant is cost-effective and feeds directly into the grid during the day, while a storage system allows solar power to be used in the evening and increases self-consumption by 70–90%. Both options can be implemented efficiently with DRBO Greenenergy.
What is a balcony power plant?
A balcony power plant is a compact plug-and-play solar system consisting of 300–800 Wp modules, a microinverter, and a Schuko plug. It feeds electricity generated during the day directly into the household grid. Installation takes approximately 30 minutes and does not require a permit for systems up to 800 W. The annual yield in Germany is 400–700 kWh, and the cost is €200–€500. Payback occurs in 2–4 years.
What is a balcony power plant storage system?
A balcony power plant storage system supplements the system with a 1–5 kWh battery to store electricity generated during the day for evening use. This increases the self-consumption rate to 60–80%. Lithium batteries, e.g., SunLit from DRBO Greenenergy, offer approximately 95% roundtrip efficiency. Storage solutions range in price from €800–€1500. Ideal for households with higher evening consumption or EV charging.
What are the costs for a balcony power plant and storage?
A balcony power plant costs €0.30–€0.50/Wp, with storage adding €500–€1000/kWh capacity. DRBO Greenenergy offers complete packages including SunLit storage systems.
| System Type | Purchase Cost | Subsidies | Payback Period |
|---|---|---|---|
| Balcony power plant | €300–€600 | €0–€200 | 2–4 years |
| With storage | €900–€2000 | €200–€500 | 4–7 years |
What is the energy yield with and without storage?
Without storage, 30–50% of the electricity is consumed directly, and the rest is fed into the grid. With storage, self-consumption increases to 70–95% as electricity is used in the evening. A 600 Wp system generates 500–700 kWh/year in Central Europe. Storage systems buffer up to 80% of the electricity, controlled via an app for optimizing charging times.
Why do tenants choose a balcony power plant?
Tenants benefit from quick and easy installation without drilling or permits. Systems up to 800 W are legal and have integrated RCD protection. Electricity cost savings amount to €20–€40/month. DRBO Greenenergy delivers turnkey sets including all components.
When is a balcony power plant storage system worthwhile?
A storage system is worthwhile for high evening consumption (>3 kWh/day) or high feed-in tariffs. Autonomy increases, and feed-in losses decrease. The break-even point is 4–6 years, especially suitable for families or households with an electric car.
What are the advantages of a balcony power plant without storage?
-
Low entry price
-
No space required for battery
-
Immediate feed-in
-
Easy handling
Disadvantage: Use only during the day, self-consumption limited to approx. 30%.
What are the disadvantages of a storage system?
| Disadvantage of Storage | Comparison to Balcony Power Plant |
|---|---|
| Higher price | Inexpensive |
| More space required | Compact |
| Charging losses 5–10% | Directly used |
| Longer payback period | Quick |
Despite higher costs, a storage system offers significantly more independence.
Can balcony power plants be expanded?
Yes, an existing balcony power plant can be upgraded later with a SunLit storage system. Hybrid systems with bidirectional inverters allow for seamless expansion. DRBO Greenenergy offers suitable upgrades and complete packages.
DRBO Greenenergy Expert Opinions
"For tenants, we recommend balcony power plants as a cost-effective entry point. For higher consumption, we recommend SunLit storage systems for up to 80% self-sufficiency. DRBO Greenenergy combines both in plug-and-play packages with Deye inverters and local support. This allows users to effectively implement the energy transition and maximize their self-consumption." – Expert at DRBO Greenenergy
Is funding available for storage systems?
Yes, KfW 270/442 and EEG amendments enable funding of up to 30%, and balcony power plants are often tax-free. Regional subsidies can amount to an additional €500.
Conclusion
A balcony power plant is ideal for beginners with daytime consumption, while storage is for maximum self-sufficiency and nighttime use. Start with a 600 Wp set from DRBO Greenenergy and expand later with a SunLit storage system. Calculate consumption, check for funding, install facing south, and save up to €500/year.
