As Europe accelerates its shift toward renewable energy, cybersecurity experts are sounding the alarm about potential threats to solar power systems, especially smaller, decentralized installations like rooftop solar panels. A recent report by SolarPower Europe and DNV, a global risk management firm, highlights the urgent need for enhanced protection of these systems amid growing energy security concerns.
The move from a centralized energy grid to a more decentralized model brings many advantages but also exposes new vulnerabilities. While solar energy is often considered safer compared to traditional energy sources, smaller solar systems, especially those linked to cloud services provided by manufacturers or service providers, are particularly at risk. This vulnerability poses a significant challenge to energy security, as decentralized systems, when aggregated, can form virtual power plants that could have a large-scale impact on the grid.
Recent incidents underscore the increasing risks to solar energy systems. In 2023, some Romanian solar customers altered their inverter settings to bypass safety functions required for grid stability, putting the grid at risk for financial gain. Another case saw a pro-Russian hacker group steal the login credentials of 22 solar sites in Lithuania, revealing weaknesses in the sector’s cybersecurity defenses.
The report urges for updated cybersecurity policies designed to meet the unique needs of the solar energy industry. These distributed energy systems currently lack the stringent protections that are required for larger, centralized energy infrastructure. Laws intended for traditional grids need to be revised to ensure that smaller, decentralized solar systems are properly protected.
To address this, experts recommend adopting a strategy similar to the GDPR, where control over distributed devices would be limited to regions with equivalent security standards, like the EU. Additionally, high-risk entities, such as solar manufacturers and service providers, must be required to implement cybersecurity measures that are thoroughly tested and approved by the relevant authorities.
In conclusion, to safeguard Europe’s clean energy future, immediate steps must be taken to secure the solar sector against potential cyberattacks, ensuring that the continent’s renewable energy transition remains resilient and safe from disruptions.
