Flexible Storage System
The solution for more self-consumption & independence - Flexible Storage System
The sun shines, and the rooftop PV plant produces clean electricity. Wouldn’t it make sense to use this electricity here and now in order to do the washing or clean the dishes?
It would make sense – for a number of reasons: With self-consumption of solar electricity, plant operators have increased independence from energy suppliers and thus from potentially rising energy prices. Moreover, the self-produced energy is used more efficiently since no losses in transit arise. And finally, electricity consumed directly where it is generated also reduces grid loads, thereby avoiding grid expansion. Thus, as high a proportion of self-consumption as possible as a result of skillful energy management is the key to a decentralized energy supply from renewable sources and the right way for a future "smart grid" development.
Energy Management Components
Successful energy management is based on three successive steps:
- Comprehensive analysis, forecasting and information
- Automatic load controls
- Intermediate storage of energy
While the increase in self-consumption stagnates with larger storage capacity, the level of battery use is steadily decreasing. If a backup function is not needed, a smaller storage system is thus the more cost-effective choice.
