Technical FAQs 4

How much electricity does a balcony solar system generate in Germany?

*Data based on average user scenarios of a balcony solar system in Germany. The annual power generation of Anker SOLIX RS40P is 890kWh; the annual power generation of an alternative balcony solar system is 757kWh. The electricity price was €0.40/kWh in August 2023.

Will smart solar buildings meet Europe's energy security needs by 2030?

Our modelling shows, that by 2030, smart solar building solutions could meet more than half of EU daily energy system flexibility needs, and a third of its annual flexibility needs. That means a more cost-effective system, resilient to shocks and strengthening Europe’s energy security.

Why are balcony solar systems becoming more popular in Europe?

The rapid urbanization of Europe has been a key driver in the growth of balcony solar systems. With over 70% of Europeans living in urban areas, many in apartments, traditional rooftop solar installations are often not feasible.

Can a balcony Solar System be installed in Switzerland?

In Switzerland, balcony solar systems are treated as regular electrical devices. Systems up to 600 watts can be installed without special permission, though they must be registered with the local energy supplier. The Netherlands has a favorable environment for balcony solar, with systems up to 1000 watts allowed without special permits.
