Due to legal regulations, maximizing self-consumption and minimizing grid feed-in are financially rewarded. As a result, installing battery storage systems based on one’s own electricity consumption is becoming increasingly attractive. But how should the storage system be sized? What are the advantages and disadvantages of having your own energy storage system? Thanks to the transition to electric mobility, your own solar power can also be used to charge your electric vehicle. But this, too, raises questions: How can I integrate my solar power system with my electric car? How can I charge my electric car most efficiently? This in-depth presentation is designed to provide answers to precisely these questions.

In Part 9 of the independent, comprehensive online information session on Wednesday, April 29, 2026, from 6:00 p.m. to 7:30 p.m., a detailed overview will be provided on the topic of optimizing self-consumption through storage and e-mobility. The session will provide an overview of the options for optimizing personal electricity consumption and draw on the speakers’ experiences to explain the advantages and disadvantages of battery storage systems and discuss the appropriate sizing of storage systems. 

In addition, the connection to mobility using solar power will be explored, and ways to optimally charge your own electric vehicle will be highlighted. This practical, expert-led presentation is supplemented by real-world case studies and provides an opportunity to ask questions directly to the experts and experienced community members, so that you can then take the next steps toward installing your own rooftop PV system with energy storage or adopting e-mobility.

The event is part of the “Solar and Heat” online seminar series. 

“Given the current conditions and to stabilize the power grids, a high level of self-consumption of solar power makes sense. Therefore, in addition to a solar system, installing a storage unit and switching to an electric car are also good options,” emphasizes Janina Steinkrüger, Head of the Environmental Department, in reference to the ninth event in the “Solar” online seminar series. 

The information series is organized by climate protection managers in collaboration with adult education centers and the consumer advice center in the Rheinhessen-Nahe and Vorderpfalz regions.
