Our security system protects solar power plants by detecting intrusions and sending email alerts, while deterring intruders with light and sound.
When the photosensor detects an intrusion, a revolving light with siren and LED lights are used to deter the intruder. Additionally, abnormal events are reported via email. The history of detected anomalies, such as intrusions, can be checked on the L・eye monitoring screen.

Theft Damage at Solar Power Plants Rapidly Increasing
The theft of metal items, such as copper wire cables, at solar power facilities has seen a sharp rise, with the damage in fiscal year 2023 reaching the highest level ever recorded. Authorities, including police across various prefectures and the Japan Photovoltaic Energy Association (JPEA), have issued alerts regarding the growing number of theft incidents at solar power facilities. In Ibaraki Prefecture, which has the highest number of metal thefts nationwide, approximately 58% of the metal thefts that occurred in fiscal year 2023 took place at solar power facilities. Once a theft occurs, it not only causes power generation to halt but also requires a significant amount of time and cost for recovery, potentially having a major impact on revenue.


When anomalies such as intrusions are detected, email alerts are sent to the registered destinations. The history of detected anomalies can be checked on the L・eye monitoring screen.

Provision Method
Customers already using the L・eye or Solar Legato package can also install the system as a retrofit. Multiple units can be installed as well. We also offer the option to add security equipment or LED lights only.
*The addition of the security system to the salt damage package is not possible.

Important Notes
- This product and service do not completely prevent damage caused by crimes such as theft. To achieve more effective security, it is important to combine multiple countermeasures.
- It cannot be used in salt damage areas.
- A contract for the remote monitoring system service, L・eye monitoring screen, is required.
- Customers using plans other than the "FL" or "Power receiving and transforming" plans in the package cannot measure contact signals other than the motion sensor of the security system. If you wish to measure other contact signals, please apply for the "FL" or "Power receiving and transforming" plan.
※The "Low Voltage FL" plan in the Solar Legato package is excluded. - If you want to incorporate the camera image option into the "Standard Boxless" plan for High Voltage 2-4, the "FL Additional Type" installation cannot be used.
