Solar Farm Perimeter Security System
Protect utility-scale PV sites against cable theft, equipment intrusion and unauthorized access with fiber optic monitoring designed for long perimeters, remote operations and varied terrain.
Challenges
A single break-in can damage equipment, interrupt power generation, and leave operators facing costly repairs.
Copper Theft and Vandalism Threaten Solar Farms
Remote Solar Farms Are Hard to Patrol at Night
Wind and Wildlife Trigger Repeated Fence Alarms
Locating Intrusions Along Solar Farm Fences Takes Time
Our Solution
Gato uses F5 zone-based fiber sensing and F7 distributed acoustic sensing (DAS) to detect cutting and climbing attempts along solar farm fences. Passive sensing fiber reduces the need for powered detectors along remote boundaries. F7’s AI models help filter environmental interference, while zone-based and location-based alarms guide security teams to the affected fence section. E3 DTS can be added where selected power cables require temperature monitoring.

Reduce Nuisance Alarms and Locate Intrusions
Product Technologies
F5 — Zone-Based Solar Farm Protection
Monitors defined fence sections around solar arrays and equipment areas. Zone-based alarms help security teams identify which part of the site needs inspection.
Zone-based detection for defined fence sections.
F7 DAS — Long-Range Perimeter Detection
Monitors long solar farm boundaries and locates intrusion-related vibrations. AI models built from positive and negative samples help identify potential intrusions and filter interference from wind and wildlife.
Intrusion-related vibration monitoring and event location.
E3 DTS — Power Cable Temperature Monitoring
Measures temperature along sensing fiber installed near selected power cables and suitable electrical assets, identifying abnormal heating and its location.
Temperature monitoring along designated power cable routes.
Applications
Utility-Scale Ground-Mounted PV Plants
Large ground-mounted solar farms have extensive fencing around solar arrays, inverter stations and cable routes. F5 provides zone-based detection along divided fence sections, while F7 monitors longer boundaries and locates intrusion events. Alarm locations can be matched to site access roads to help security teams reach the affected area.
Desert and Arid-Region PV Plants
Desert solar farms often operate with few on-site guards, while strong winds and wildlife can interfere with perimeter alarms. Passive sensing fiber reduces the need for powered detectors along remote fences. F7's AI models can be configured using site-collected data to help filter background vibrations.
Hilly and Irregular-Terrain PV Plants
Solar farms built across hills and valleys often have winding fences that are difficult to inspect from a single location. Fiber optic sensing can monitor suitable fence sections across changing terrain, while location-based or zoned alarms help guards identify where to investigate and which access route to use.
Case Studies
E3 DTS Evaluation for a Spanish Renewable Energy Provider
Project Requirements
A Spanish clean energy provider included E3 DTS in its supplier-evaluation process while exploring continuous temperature monitoring for selected electrical assets as its renewable-energy projects expanded.

Frequently Asked Questions
Can fiber optic perimeter sensing be added to an existing solar farm fence?
Usually, but the existing fence should first be checked for stability, damaged mesh, loose posts, uncontrolled vegetation, and sections that move excessively in normal weather. The cable route must also be protected from maintenance vehicles, mowing equipment, livestock, and future civil work. Where the fence condition varies around the site, the solar farm perimeter security system may require different installation approaches for different sections.
Will perimeter monitoring continue if power is lost at a remote solar farm?
The sensing cable itself may be passive, but the host equipment, communications, monitoring platform, and any supporting devices still require power. Continued monitoring during an outage therefore depends on the project’s backup-power and network design. The required operating duration and alarm-reporting method should be defined during design rather than assumed from the use of passive fiber along the fence.
How can a damaged sensing cable be repaired at a remote solar site?
The maintenance team should identify and secure the affected section, then use a suitable fiber repair or replacement method for the installed cable. Connections must be protected against the local environment and accidental mechanical damage. Before the route is returned to service, optical condition, alarm-location mapping, and representative fence events should be checked. Keeping route drawings and approved repair materials on site can shorten recovery time.
How do we choose between F5 and F7 for a solar farm?
F5 is suitable for segmented boundaries where zone-level alarms are sufficient, subject to confirmation of the selected F5 configuration. F7 is suited to long perimeters requiring event location and is available in single- or dual-channel configurations with 5 km, 15 km, 25 km or 50 km per channel. Final selection depends on the perimeter layout, required alarm resolution and cable-route design.
