Anti-theft system for solar panels

This system protects every single solar panel, triggering an alarm in case of theft attempt. Plastic fiber LiteWIRE links all the solar panels like a chain and is connected to a LiteSUN Plus analyser. Only bends and the cut of the fiber during a theft attempt can trigger an alarm. This system is not sensitive to vibrations, so weather conditions (like wind, rain or snow), leaves and birds do not trigger any false alarms. In addition, as plastic fiber is an insulating material, the system is not affected by any electromagnetic noise.

If only the cut of the fiber needs be detected a simpler analyser, LiteSUN, can be used.

How it works

This system works like a chain: the fiber plastic is attached to the solar panels to link them together and is connected to the analyser LiteSUN Plus, which can detect both the cut and the bend of the fiber. When an attempt of theft results in deformation or interruption of the fiber, the optical analyser LiteSUN Plus detects the variation of the light signal and triggers an alarm. After that, if the fiber has remained intact, the system resets automatically, adapting to the (new) position.

This anti-theft system is composed of 3 elements:

LiteSUN Plus analyser, which sends a light signal and analyzes the flow of light

received, generating an alarm both when the cable is cut and when the cable is

bent or stretched out.

– Plastic fiber cable LiteWIRE (with anti-UV filters for installation in the direct sunlight) which transmits the light signal

Affixing elements which secure the fiber to the solar panels:
drilled bolts: the rectangular nut cannot be unscrewed if the fiber is inserted in the head.

drilled pins: quick to position, only for rooftop installations

fast bolts: quick to install, they make any maintenance easy, because the fiber can be fastened and removed quickly. Of course, it must be used only in combination with LiteSUN Plus, sensitive both to bend and cut of fiber.

special glue (NEW!) fixes the fiber to the panel with little effort and cost-effectively. It is used in combination with LiteSUN Plus, sensitive both to bend and cut of fiber.

If only the cut of the fiber needs be detected a simpler analyser, LiteSUN, can be used.

Every analyser manages up to 300m of fiber, either in a loop connection or in a point-to-point connection. According to the connection scheme, LiteSUN Plus can be used as a single transmitter, receiver, repeater or single loop transceiver.

In order to check that the fiber is installed correctly throughout the installation process, the LiteSUN Plus can have a user-friendly, built-in Power Meter.

Advantages

  • Zero false alarms
  • Zero maintenance
  • Plastic fiber cable LiteWIRE is used

Frequently Asked Questions

How many panels can I protect with one analyser?

It depends on how the panels are laid and what the distances between the panels are. Approximately 200 panels can be secured with a single analyser

Can I repair the fiber? How can I terminate the fiber?

Yes, the fiber can be repaired mechanically, using a coupler which joints two connectors. To terminate the fiber you can use asic electrician’s tools, as shown in this video on fiber termination.

What type of alarm do I get?

LiteSUN Plus gives an alarm when the fiber is cut or bent/stetched out. It has a single, normally closed relay output, which can be connected to an alarm panel of any kind.
