Introduction
Solar farms are among the UK’s fastest-growing infrastructure assets – and among its most vulnerable. Sprawling across hundreds of acres of open, often rural land, these sites present a security challenge that standard CCTV and basic fencing simply cannot meet alone. With copper cable theft from UK solar farms exceeding 750km in 2024 alone, and a reported 48% rise in solar panel theft between 2021 and 2022, operators can no longer afford to rely on reactive security measures.
The answer lies in fence intrusion detection – intelligent, sensor-based technology that detects a threat the moment it touches your perimeter, not after it has already breached it.
At Sysco Tech, we specialise in designing and deploying perimeter intrusion detection systems (PIDS) purpose-built for large open sites like solar farms.
This guide explains why fence protection is critical for renewable energy sites, what makes a solar farm uniquely difficult to secure, and how the right fence intrusion detection system changes everything.
Why Solar Farms Are a Prime Target
Solar farms tick every box for organised criminals. They are isolated, often unmanned, and packed with high-value assets – copper cabling estimated at 4 to 5 tonnes per megawatt, inverters, and panels that can be stripped and sold rapidly. Aviva Insurance reported that theft claims for UK solar farms exceeded £250,000 in just three months between December 2023 and February 2024.
The pattern is consistent: criminals conduct reconnaissance, identify the weakest point in the perimeter, and return – sometimes more than once. Research shows that 50% of solar farms that experience one theft go on to experience a second. Without a proactive, detection-led approach to fencing and security, sites remain perpetually exposed.
Basic agricultural fencing – deer fencing, stock fencing – offers no meaningful resistance or deterrent. It was designed to contain livestock, not stop organised gangs. Planning authorities have begun to acknowledge this: a site in Wakefield was rejected in 2023 specifically because its proposed deer fencing perimeter was deemed insufficient.
The solution has to start with fence intrusion detection.
The Unique Perimeter Challenge of Solar Farms
What makes solar farm perimeter security so complex is the sheer scale. A utility-scale solar farm can cover 50 to 500 acres. Traditional perimeter protection approaches – motion sensors, guard patrols, fixed CCTV – struggle to provide reliable, continuous coverage across perimeters that may stretch several kilometres.
The environment compounds the challenge. Uneven terrain, rolling hills, ditches, and sloped ground make standard fence-mounted systems unreliable unless engineered for variable outdoor conditions. Wind, rain, and wildlife are constant sources of false alarms for poorly calibrated systems, leading security teams to disengage or ignore alerts entirely.
Rural locations often lack fast emergency response, meaning detection must happen early enough for a meaningful intervention before assets are removed. Local planning restrictions may limit fence height or visual impact, meaning the fence itself cannot always carry the full security burden alone.
This is precisely why fence intrusion detection must do more than simply sense vibration. It must intelligently distinguish genuine threats from environmental noise, precisely localise the intrusion zone, and trigger an integrated response – all in real time.
How Fence Intrusion Detection Works on Solar Farm Perimeters
A fence intrusion detection system transforms a passive physical barrier into an active, intelligent security layer. Sensors are mounted directly onto the fence structure and continuously monitor for vibration patterns associated with climbing, cutting, or lifting the fence.
At Sysco Tech, our fence intrusion detection systems use advanced vibration sensing technology that analyses the frequency, duration, and pattern of fence disturbance. The system distinguishes between benign movement – caused by wind, rain, or an animal brushing the fence – and a genuine intrusion attempt. When a real threat is detected, the system triggers an alert, logs the zone, and can simultaneously activate CCTV, lighting, and audio deterrents.
Our core technologies for solar farm deployments include:
- SP3D (Single Point 3D Sensor) – ideal for concealed or direct outdoor installation, protecting targeted fence sections cost-effectively. Particularly useful for access gate areas or corners where intrusion is most likely.
- EcoPoint – designed for long fence runs, this sensor is perfect for the extended perimeters typical of utility-scale solar farms, providing reliable coverage across significant distances without compromising detection accuracy.
- FlexLine – our cable and point sensor hybrid, designed for high-security environments where operational reliability cannot be compromised. For solar farms with assets worth millions, FlexLine provides the gold standard in fence protection.
All systems integrate seamlessly with CCTV, video analytics platforms, access control, and control room infrastructure – including SCADA systems commonly used in energy sector operations.
What Good Fencing and Security Looks Like for Solar Farms
Effective fencing and security for a solar farm is not a single product – it is a layered, integrated system designed around the site’s specific risk profile.
Layer 1 – Physical Fence Barrier:
A security-rated fence (ideally LPCB SR1 certified) at a minimum height of 2.5 metres, with anti-climb features, tamper-resistant fixings, and wildlife-friendly lower access points where planning requires. Compliance with British Standard BS 1722-14 for mesh panel fencing is strongly recommended.
Layer 2 – Fence Intrusion Detection:
Sysco Tech’s sensor-based PIDS are mounted to the fence structure, providing zone-by-zone detection across the entire perimeter. The system pinpoints exactly where an intrusion attempt is occurring, enabling a precise, targeted response rather than a site-wide alarm.
Layer 3 – Integrated Video Verification:
When a fence intrusion detection alert is triggered, integrated CCTV – ideally with thermal imaging for night-time coverage – automatically activates and focuses on the affected zone. Remote monitoring teams can verify the threat in seconds, eliminating false callouts and enabling faster police response.
Layer 4 – Response and Deterrence:
Automated audio warnings, high-intensity lighting, and alarm systems act as immediate deterrents. Remote monitoring teams can intervene with live audio challenges and, where necessary, dispatch keyholders or police.
Frequently Asked Questions About Fence Intrusion Detection for Solar Farms
What is fence intrusion detection, and how does it differ from CCTV?
Fence intrusion detection uses sensors mounted on or within the fence structure to detect physical contact – climbing, cutting, or lifting. Unlike CCTV, which relies on visual detection and can be defeated by darkness, fog, or camera placement, fence intrusion detection is tactile. It detects the threat at the fence line itself, before an intruder has entered the site.
Can fence intrusion detection systems cope with UK rural weather conditions?
Yes -when correctly specified and installed. Sysco Tech’s systems are designed for outdoor deployment in UK weather conditions. Advanced signal processing filters out wind-induced fence movement, rain, and minor vibrations from wildlife, ensuring alerts are genuine rather than environmental.
How many sensors are needed to cover a large solar farm perimeter?
This depends on perimeter length and chosen technology. EcoPoint sensors are designed for long fence runs and can cover extended distances efficiently. Sysco Tech conducts a full site assessment to design a system that provides complete coverage without over-specifying.
Does fence intrusion detection integrate with existing CCTV systems?
Yes. Sysco Tech’s systems are integration-ready and connect to your existing CCTV, access control, and alarm infrastructure – enhancing your existing investments rather than replacing them.
Is fence intrusion detection a requirement for solar farm insurance in the UK?
Increasingly, yes. Major UK insurers recommend or require evidence of active perimeter security systems. A properly installed fence intrusion detection system can support insurance claims, reduce premiums, and demonstrate due diligence in the event of a claim.
What happens when a fence intrusion detection alert is triggered?
The system logs the zone and time of detection, triggers linked CCTV to focus on that area, and sends an alert to your monitoring platform or remote monitoring team. Integrated audio and lighting deterrents activate automatically, and your response team can verify and act within seconds.
The Cost of Not Acting
The financial impact of a single breach at a solar farm is substantial. Beyond the immediate replacement cost of stolen copper – often tens of thousands of pounds per incident – operators face operational downtime, insurance complications, and the very real risk of being revisited. Organised gangs return to sites they know are poorly secured. Without effective fence protection, sites become repeat targets, sometimes within weeks of restoration.
Proactive fence intrusion detection is not just a security investment. It is a business continuity investment.
