Cybersecurity for PV Systems

The energy sector is becoming increasingly digital—and, as a result, increasingly vulnerable. Photovoltaic systems have long been part of critical infrastructure and are increasingly becoming a target of cyberattacks.

Attackers rarely target individual components such as inverters; instead, they exploit the entire system landscape—from cloud platforms and communication interfaces to external service providers. At the same time, regulatory requirements are increasing. With the NIS2 Directive, the European Union requires companies in the energy sector to implement comprehensive cybersecurity measures—ranging from risk management and incident reporting to securing the entire supply chain. Violations can not only result in heavy fines but also pose personal liability risks for management.

Three questions—three seconds. If you answer any of them with “No” or “I don’t know”—you’re affected.

01

Do you know who might be able to access your inverters from the Internet tonight?

02

Would you be able to detect a cyberattack within 24 hours—and report it within 72?

03

Can you relieve your management team of some of the burden during the audit?

EU Directive on Cybersecurity in Critical and Important Sectors—including energy. Requirement to transpose into national law.

Energy producers, grid operators, and utilities with 50 or more employees or €10 million in revenue—and their IT service providers. This also applies indirectly through the supply chain.

10 Responsibilities: Risk Management, Incident Reporting, Supply Chain, Cryptography, MFA, Training, Contingency Plans, Security Testing, Patch Management, Governance.

Fines of up to €10 million or 2% of annual revenue. Personal liability of management. Regulatory orders, audits, and prohibitions.

The 10 NIS2 Requirements — At a Glance.
  • Risk Analysis & Security Concepts
    Structured Risk Assessment for IT, OT, and the Supply Chain.
  • Business Continuity & Backup
    , RTO/RPO defined, backups tested.
  • Secure Procurement & Development
    Security by Design, Patch Management, Secure Configuration.
  • Cyber ​​hygiene & training
    Awareness training, phishing exercises, OT-specific training.
  • Access Control & Asset Management
    , MFA, Roles, Inventory—from modules to the cloud.
  • Incident management
    Emergency plans, forensics, restart.
  • Supply Chain Security
    Direct sellers, manufacturers, and IT service providers are contractually bound.
  • Assess the effectiveness of the measures
    Audits, penetration tests, KPIs — regularly documented.
  • Cryptography & Encryption
    : Data in transit and at rest—including in OT protocols.
  • Secure authentication

NIS2 reporting chain: 24 / 72 / 30

24 hours

Initial Report

Early warning to the relevant national authority (in Germany: BSI).

72 h

Update

Detailed Assessment: Impacts, Indicators, Mitigation Measures.

30 days

Final Report

Comprehensive root cause analysis, lessons learned, follow-up actions.

Anyone who misses the 24-hour deadline risks fines of up to €10 million or 2% of revenue. Without prepared reporting templates and designated responsible parties, no one can manage this.
