Solar Power Sector Faces Major Cybersecurity Threat: Study

Alarming news has emerged from the renewable energy sector. Researchers from Forescout's Vedere Labs have identified significant vulnerabilities in the top six solar power system manufacturers. This discovery raises serious concerns about the security of power grids worldwide, particularly in the US and Europe, where solar energy is increasingly prevalent.

The study found critical flaws in the systems produced by Sungrow, Growatt, and SMA. These vulnerabilities could potentially be exploited by cyber-threat actors, leading to grid failures and blackouts. The researchers warned that modern power generation solutions, such as solar inverters and communication dongles, are particularly vulnerable and challenging to defend.

The dominance of Chinese firms in the solar power component market also poses a potential national security threat. The three leading manufacturers of solar cell systems worldwide, Longi, JinkoSolar, and Trina Solar, have addressed these issues by enhancing module resilience through innovations like glass/glass module designs and advanced cell technologies like TOPCon and HIBC. However, the threat remains real, as evidenced by three significant cyber incidents in 2024 that exploited solar power systems, leading to an FBI industry notification in July of the same year.

In total, 46 new vulnerabilities were discovered across different components in the affected solar power systems. These findings underscore the urgent need for robust cybersecurity measures in the renewable energy sector to protect power grids from damaging attacks.

The discovery of these vulnerabilities serves as a stark reminder of the importance of cybersecurity in the renewable energy sector. As solar power continues to grow, so too must our efforts to protect these systems from malicious actors. Stakeholders must work together to implement robust security measures and ensure the resilience of our power grids in the face of evolving threats.
