Solar park security: protecting cables and equipment from theft
A solar park is protected when three things work together: the fence delays an intruder, detection alerts a person immediately, and the response arrives before the cable is loaded. Because parks are remote and unstaffed, the plan sets out who sees the alarm, who goes, how maintenance crews get in, and what is recorded for the police and the insurer.

Why is a solar park hard to secure?
Because it is large, remote and empty: nobody sees what happens, and whoever is alerted needs time to get there. Security is designed so the fence holds an intruder up for longer than the response takes to arrive.
- Size: a long perimeter, rows of panels, and places where someone can work unseen.
- Distance: farm tracks, no neighbours to raise the alarm, travel time for whoever responds.
- No staff on site: without detection, a theft shows up at the next visit or when output drops.
- Night: little or no lighting, and a quiet setting for anyone arriving by vehicle.
So the question isn’t “guard or cameras” but how delay, detection and response fit this particular plot. Start with a site survey: where the gates, access tracks and blind spots are, and where the most valuable equipment sits.
What fencing and detection does a solar park need?
A fence with no gaps and locked gates, detection on the fence line or across the park’s zones that alerts a person at once, and cameras that let the alarm be verified before anyone is sent. Detection that only records is an archive, not protection.
- Fence: continuous, no gaps at ground level, with gates that lock and are checked.
- Clear strip: vegetation cut back along the fence so it neither hides gaps nor confuses sensors.
- Zoned detection: the alarm says exactly where something happened, not just “something in the park”.
- Verification: a camera view of the zone, to tell an animal or the wind from a person.
- Recipient: who receives the alarm, what they do and whom they call, written down before the first night.
If there are cameras, signs go up before their field of view, naming the controller, the purpose and a contact for data-subject rights (Directive 1/2011, art. 12).
At the industrial sites OVIT protects, fence-line detection routes straight to the officer on duty (industrial and logistics). For when a system is enough and when a person is needed, see guard or security system.
Which solar park equipment is at risk, and how is it protected?
Copper cable, inverters and electrical equipment, panels, and materials or tools left on site. The risk changes with the phase: during construction there are open trenches and stored materials; in operation the equipment is installed and the site is empty.
- Cable: in trenches, trays and connections. Check where it is exposed, and close pits and junction boxes.
- Inverters and electrical gear: in locked rooms or cabinets, with door-open detection and recorded serial numbers.
- Panels: recorded by row, so a loss can be pinned to a spot.
- Materials and tools: the less left on site, the better; whatever stays goes in a locked container with an inventory.
- After every job: check that pits, cabinets and gates were closed.
During construction the park is a building site with all the risks that brings: see the guide to construction site theft. The damage is not only the copper: lost generation until the circuit is restored counts too.
Patrols or remote monitoring for a solar park?
Usually both: detection and cameras see the event, and a mobile patrol goes to check it. A permanent guard on site makes sense in higher-risk periods, such as construction or the days after an incident.
- Remote monitoring: sees the whole park all the time, but stops nobody on its own; someone has to be sent.
- Mobile patrol: checks the alarm on site and runs scheduled rounds, time-stamped at each checkpoint.
- Static guard: present for the whole shift, useful while materials are stored or trenches are open.
The trade-off is covered in static guarding or mobile patrols, and checkpoint rounds in patrols with NFC and QR. Whoever goes to the park, ask for their personal work-licence number — category A or B, valid five years (Law 2518/1997, art. 3).
How should maintenance crews’ access to a solar park be controlled?
Every visit is announced in advance: who, from which company, in which vehicle, for what work, in which zone and at what times. On arrival the details are checked against the notice and departure is logged, so legitimate presence can be told apart from an intrusion.
- The park operator notifies the operations desk or the security lead of the visit.
- On arrival, people, company and plate are checked against the notice.
- Detection in the work zone is disarmed only for the time and area of the job.
- On departure, gates, cabinets and pits are checked closed, and no undeclared material leaves.
- Detection is re-armed and the visit is closed in the log with times and names.
An unannounced visit is treated as an alarm until a named, reachable person on the client side confirms it.
Keys and codes are issued by name and changed when the contractor changes. What the officer does in each case belongs in the post orders.
How do you document a solar park theft for the police and the insurer?
With a record where every step has a time and a name: when detection fired, who verified it, who went and when they arrived, what they found, what is missing and when the police were told. Exactly what the insurer needs is set by the policy, so ask before the first incident, not after.
- Timeline: alarm, verification, dispatch, arrival, actions, closure.
- Damage: which zone, which circuits, which equipment, with serial numbers where available.
- Evidence: photos, a video clip, vehicle tracks, the points where the fence was breached.
- Notifications: who was told — client, police, insurer — and when.
Video has limits: delete within 15 working days at most if nothing happens; footage of an incident against the business may be kept up to 30 days, and of one involving a third party up to 3 months (Directive 1/2011, art. 8). Decide the same day what is kept. What a good report contains is set out in the incident report guide.
At OVIT every exception closes into a structured file that can be exported for audit or investigation, the client sees rounds and incidents in one live picture through the Guardly platform, and a real person answers the operations desk. Request a proposal for your park.
At a glance
- The fence must hold an intruder up for longer than the response takes to arrive.
- Zoned detection is only worth having if it alerts a person who knows what to do, at once.
- Cable, inverters, panels and materials carry different risks during construction and in operation.
- Every crew visit is announced in advance; an unannounced visit is an alarm.
- Timeline, damage, evidence and notifications, each with a time and a name: that is what police and insurers need.
Frequently asked questions
What equipment is at risk in a solar park?
Copper cable, inverters and electrical equipment, panels, and materials or tools left on site. Risk is higher during construction, when trenches are open and materials are stored.
Are cameras enough for a solar park with no guard?
Not on their own. A camera sees the event, but someone must receive the alarm, verify it and send a patrol. Without a response, the camera just records the theft.
What does the insurer need after a theft at a solar park?
The policy decides, so ask in advance. In any case, keep a timeline with times and names, a description of the damage with serial numbers, photos, video, and when the police were notified.
