How does a Balcony Solar Power System with storage perform in autumn?
Fluctuating conditions
Autumn brings shorter days and changeable weather, which makes energy production from a balcony power plant more challenging. Nevertheless, a Balcony Solar Power System with storage can still work effectively during this transitional period.
- Generation: On sunny autumn days, your solar modules can still generate 2–3 kWh per day.
- Storage: The storage unit ensures that no energy is lost, even in changeable weather.
Important functions of the storage facility in autumn
| Autumn advantage | Explanation |
| Time-based storage | The storage system can store electricity at favourable times and use it when needed. |
| Weather independence | Even in cloudy weather, the storage system can maximise the use of the electricity generated. |
How does a Balcony Solar Power System with storage perform in winter?
Less light, higher efficiency thanks to storage
Winter poses the greatest challenge for solar systems. The days are short, the sun’s rays are weak, and clouds often cover the sky. Nevertheless, a Balcony Solar Power System with storage can still be useful during the cold season.
- Generation: On a clear winter’s day, a 900-watt Balcony Solar Power System with Storage can generate around 0.6–1 kWh of electricity.
- Storage: The storage unit ensures that even this small amount of energy is not lost.
