Shell Exits Battery Business, Sells Sonnen
Shell has sold its residential battery unit Sonnen to Munich‑based asset manager Tiven for a low‑hundreds‑of‑millions‑euro price, ending a several‑year venture.
Solar energy storage lets Israel capture excess photovoltaic (PV) power and use it when the sun isn’t shining, cutting electricity bills and boosting grid reliability. This guide explains how storage works, the key technologies and players, costs in NIS, regulations, and what the future holds for rooftop and utility‑scale systems.
