In Switzerland, balcony power stations are becoming increasingly popular — especially among renters or people who cannot install a large solar system. But for those who own their home, the key question arises:
Is a balcony power station really the best solution — or am I missing out on much greater savings from a full solar installation?
What is a balcony power station?
A balcony power station is a mini solar system for personal use: typically 1–2 solar modules with an output of 300 to 800 watts, connected via a normal plug socket. The electricity produced is consumed directly in the household.

Are balcony power stations allowed in Switzerland?
Yes — generally allowed, but with clear rules. Many people underestimate the administrative requirements.
How much electricity does a balcony power station produce?
A typical balcony power station produces around 200–600 kWh per year — this corresponds to the base consumption of a few appliances (fridge, standby). This is far from covering the majority of a household's electricity consumption.
Comparison: annual production
A full solar installation produces 15–20× more electricity per year.
Balcony power station vs. solar installation — the direct comparison
For homeowners, the difference is enormous.
Conclusion:
A balcony power station is a small supplement — a solar installation is a real energy solution. For a homeowner, a balcony power station leaves thousands of francs in annual savings on the table.

Alternative: solar installation instead of balcony power station
Many start with the idea of a balcony power station and then realise: the effect is too small.
A full solar installation saves you CHF 1,500–3,000 annually — 10–20× more than a balcony power station. And with the one-time payment (OTP) and cantonal subsidies, acquisition costs are significantly reduced.

What happens if I don't register my balcony power station?+
You violate regulations and risk the system being removed or restricted. The grid operator can take measures.
How many balcony power stations can I operate?+
In most cases one system per household is intended to avoid grid problems. Multiple systems can cause feed-in issues.
Does a battery storage need to be registered?+
Yes, battery storage must also be registered depending on the system, as it can influence the electricity grid.
Can a grid operator detect my balcony power station?+
