BRUSSELS, Belgium (May 2, 2025) – European residential solar panels are vulnerable to cyberattacks that could destabilize the continent’s power grid, according to a new report. The report highlights the risk of foreign powers exploiting vulnerabilities in solar inverters, devices that convert solar panel energy for grid use.

Vulnerable Inverters Spark Concern
SolarPower Europe, in a report released this week, urges increased oversight of remote access to small photovoltaic systems. The organization emphasizes the potential danger stemming from the widespread adoption of residential solar installations across Europe.
The focus is on inverters, the connected devices that transform the direct current from solar panels into alternating current usable by the power grid.Many of these inverters are remotely controlled via cloud services, frequently enough located outside the European Union, raising cybersecurity concerns.
The lack of a stringent regulatory framework governing these connections for smaller installations is a key vulnerability, the report states.
Cybersecurity Breach in Energy Sector
The report paints a concerning scenario: a targeted attack on just 3 gigawatts of inverter capacity could disrupt a portion of the European power grid. This represents several hundred thousand residential facilities, potentially susceptible if controlled through a centralized interface from a foreign country, such as China or Russia.
SolarPower Europe advocates for strict limitations on remote access to inverters, suggesting it should only be authorized from European jurisdictions or countries with equivalent cybersecurity safeguards. This measure aims to establish digital energy sovereignty.
Huawei Example Raises Red Flags
The report highlights that Huawei, a Chinese technology company, has at least 114 GW of photovoltaic inverters installed in Europe. Furthermore, at least six Chinese manufacturers reportedly have remote control over more than 5 GW spread across European territory.
Chinese national intelligence law compels companies to cooperate with state authorities,adding a strategic dimension to the technical concerns.

The report suggests that a foreign entity could potentially destabilize the European electricity network remotely.
SolarPower Europe draws a parallel to the banishment of “unreliable” suppliers in 5G networks, questioning why similar precautions aren’t in place for critical energy infrastructure.
Remote Destabilization: No Longer Science Fiction
A recent power outage affecting Spain, Portugal, and France underscored the interconnectedness and fragility of the European grid. While not attributed to a cyberattack, the incident highlighted the potential for widespread disruption. A distributed vector, such as thousands of connected photovoltaic micro-plants, could trigger a significant imbalance.
In a tense geopolitical climate, the possibility of intentional interference is a growing concern. A hostile nation could exploit software vulnerabilities in inverter systems to deactivate equipment or inject disruptive signals into the grid.
Call for an Energy ‘GDPR’
To address these threats, SolarPower Europe proposes a regulatory framework modeled after the General Data Protection Regulation (GDPR).This would involve a binding European regulation on the cybersecurity of energy infrastructure, specific to the sector, to prevent past oversights.
With the increasing deployment of residential solar solutions, including plug-and-play solar batteries and panels that integrate cloud services and AI, individuals’ exposure to these risks will inevitably increase.The convenience of connected management should not overshadow the need for security by design, the report concludes.
Europe’s Solar Inverters Under Cyberattack Threat: Your Essential Q&A
What is the main concern regarding solar inverters in Europe?
The primary concern is the vulnerability of European residential solar panels to cyberattacks, perhaps destabilizing the continent’s power grid. A recent report highlights the risk of foreign powers exploiting vulnerabilities in the inverters that convert solar energy for grid use.
What are solar inverters, and why are they a target?
Solar inverters are devices that convert the direct current (DC) electricity produced by solar panels into alternating current (AC) electricity, which is usable by the power grid and household appliances. They are a key point of vulnerability because many are remotely controlled via cloud services, often located outside the European Union. This remote access opens the door to potential cyberattacks.
Why is remote access to inverters a security risk?
Remote access, especially from outside the EU, raises cybersecurity concerns. A targeted attack could exploit vulnerabilities in these inverters to disrupt the power grid. The report suggests that control from foreign jurisdictions, such as China or Russia, poses a significant risk.
How could a cyberattack on inverters impact the European power grid?
According to the report,a targeted attack on just 3 gigawatts (GW) of inverter capacity could disrupt a portion of the European power grid. This could affect hundreds of thousands of residential solar installations. The potential impacts include:
- Deactivation of equipment.
- Injection of disruptive signals into the grid, leading to instability.
- Widespread power outages.
What are the specific concerns about Chinese manufacturers?
The report specifically highlights concerns about Chinese manufacturers due to:
- Huawei’s Presence: Huawei, a Chinese technology company, has at least 114 GW of photovoltaic inverters installed in Europe.
- Remote Control: At least six Chinese manufacturers reportedly have remote control over more than 5 GW spread across European territory.
- National Intelligence Law: Chinese national intelligence law compels companies to cooperate with state authorities, adding a strategic dimension to technical concerns.
how does the report suggest mitigating the risks?
SolarPower europe advocates for strict limitations on remote access to inverters. They suggest that remote access should only be authorized from:
- European jurisdictions.
- Countries with equivalent cybersecurity safeguards.
This measure aims to establish digital energy sovereignty.
What’s the parallel to 5G networks?
The report draws parallels between the situation with solar inverters and the banishment of “unreliable” suppliers in 5G networks.It questions why similar precautions aren’t in place for critical energy infrastructure like solar inverters.
Has there been any real-world exmaple of the potential for disruption?
Yes, a recent power outage affecting Spain, Portugal, and France underscored the interconnectedness and fragility of the European grid. While not directly attributed to a cyberattack, the incident highlighted the potential for widespread disruption. A distributed vector, such as thousands of connected photovoltaic micro-plants, could trigger a significant imbalance.
What regulatory changes are being proposed?
SolarPower Europe proposes a regulatory framework modeled after the General Data Protection Regulation (GDPR). This would involve a binding European regulation on the cybersecurity of energy infrastructure,specific to the sector.
What are the key vulnerabilities associated with residential solar installations?
The key vulnerabilities stem from:
- Remote access via cloud services.
- Lack of stringent regulatory frameworks for smaller installations.
- Integration with cloud services and AI.
What are the risks associated with the increasing use of residential solar solutions?
With the increasing deployment of residential solar solutions, including plug-and-play solar batteries and panels that integrate cloud services and AI, individuals’ exposure to these risks will inevitably increase. The report concludes that the convenience of connected management should not overshadow the need for security by design.
Who is most at risk from these potential cyberattacks?
Homeowners using residential solar panel systems with inverters that are remotely controlled are most at risk. The potential for foreign entities to destabilize the electricity network remotely poses a significant threat to these individuals.
What’s the long-term impact if these threats are not addressed?
If these threats are not addressed, the long-term impacts could include:
- Grid Instability: Increased frequency and severity of power outages.
- Economic Damage: Disruptions to businesses and daily life due to unreliable power.
- Erosion of Trust: Loss of public trust in the security of renewable energy infrastructure.
- Geopolitical Risks: Increased vulnerability to state-sponsored cyberattacks.
ensuring the security of Europe’s solar inverters is crucial for maintaining a stable and secure energy future. The proposed regulatory changes aim to safeguard this critical infrastructure.
