1. Annual electricity generated by solar panels are based upon ideal conditions. Calculations were used from this website: https://re.jrc.ec.europa.eu/pvg_tools/en/tools.html

2. For a balcony solar power system without storage, the proportion of energy used is 42.42% and is rounded down to 40% in the example above. Data is based on 40,500 data points from Anker SOLIX users in Germany during 2024.

3. The self-consumption rate of balcony power plants with storage factors in ideal consumption time and conversion efficency, deriving from data analysis from Berlin University of Applied Sciences (HTW): (https://solar.htw-berlin.de/rechner/unabhaengigkeitsrechner).

4. Annual electricity savings are based on energy rates of €0.40/kWh, which was taken from the official average electricity rate in Germany during H2 2022.
