Copper theft crews can strip a solar site in one night, and insurers know it. RBtec turns kilometers of PV fence into zoned detection that catches the cut before the inverters are reached, with sensing that scales from one site to a whole portfolio.
Copper. Industry loss reporting puts organized copper theft at the top of the damage list for utility scale PV, with crews cutting the fence, stripping DC cable and inverter connections, and often returning to the same site weeks later. The sites are remote and unmanned, response is measured in tens of minutes, and the outage and repair costs dwarf the scrap value of what was taken. Cameras alone record the loss; the operators who break the cycle detect the fence cut while it happens.
After several loss heavy years, insurers increasingly condition coverage and premiums on real perimeter detection and verified alarm response, and underwriter questionnaires now ask about it directly. On the regulatory side, plants that reach 75 MVA aggregate registration fall under NERC as generator owners and operators, with baseline CIP physical access controls; the heavy CIP-014 requirements apply to critical transmission stations rather than PV plants, and a page one claim to the contrary would be wrong. For projects with federal or utility offtake, NDAA Section 889 sourcing rules shape the equipment list.
By making the fence the sensor instead of blanketing it with cameras. A sensing cable on the agricultural style fence divides the perimeter into zones, each tuned for wind, vegetation and livestock, so the alarm that reaches the monitoring center means something. Camera call-up verifies the alarmed zone, which keeps the camera count, trenching and power runs to a fraction of a camera only design. For the largest parks, fiber sensing covers the full boundary from a single unit.
Linearly. One processor package per site plus cable to match the fence, the same zone map logic everywhere, and the same alarm handling at the monitoring center. Developers running hundreds of sites standardize the design once and repeat it, which is what makes portfolio wide security a budget line instead of a per site project.

Whether it’s a quick question or something more complex: no pressure, just answers.
Detect the fence cut while it happens. A zoned sensing cable on the perimeter reports the cut or climb with a zone location, cameras verify it, and response starts before the crew reaches the DC cable. Sites relying on cameras alone usually get good footage of the theft instead.
Underwriters increasingly ask for detection at the perimeter with verified alarm response, not just recording cameras. A zoned fence detection system with camera verification answers the questionnaire directly. The specific requirements vary by carrier, so bring the system spec to the renewal conversation.
Plants reaching 75 MVA aggregate registration fall under NERC as generator owners and operators, with baseline CIP requirements including physical access controls. The stricter CIP-014 physical security standard targets critical transmission stations and generally does not apply to PV plants.
With fiber sensing. A single RaySense unit monitors kilometers of fence and locates events along the run, which avoids the per segment electronics and power infrastructure that make camera only designs expensive at scale.
Each zone is tuned to its own environment, and the sensing algorithms separate the broadband rumble of wind and brushing vegetation from the sharp signatures of cutting and climbing. The result is a system the monitoring center can trust at 3 a.m.
