The High Cost of Connectivity: The rapid integration of solar panels with Internet of Things (IoT) infrastructure has proven to optimize energy production by utilizing management software, inverters, and communication networks. However, with increased connectivity, the risk of cyberattacks and remote shutdowns has also increased, potentially disrupting energy production, household security and even the stability of national power grids. How can the EU support sustainable growth while ensuring the protection of renewable energy systems, particularly solar panels, from cyber-threats?
