Solar fencing

Solar fencing is a modernized and unconventional method of providing security that is both effective and efficient. It works like an electric fence, delivering a brief yet fierce shock when human beings or animals come in contact with the fence. The shock enables a deterrent effect while ensuring that no loss of life is caused 1.

Some of the features of a solar fence include:

Low maintenance cost: Solar fences are easy to maintain and require minimal upkeep 12.
Highly reliable: Solar fences function irrespective of grid failure, making them highly reliable 12.
No physical harm: No physical harm is caused to human beings or animals 12.
Cost-effective: Solar fences make use of renewable solar energy, making them a cost-effective option for security 12.
Centralized alarm system: Solar fences generally come with a centralized alarm system 12.
Conformity with safety standards: Solar fences conform to national and international safety standards 1.
Components of a solar fencing system include:

Battery
Charge control unit (CCU)
Energizer
Fence voltage alarm (FVAL)
Photovoltaic module
The working of a solar fencing system starts when the solar module generates direct current (DC) from sunlight which is used to charge the system’s battery. Depending on sunlight hours and capacity, the system’s battery can generally last for as long as 24 hours in a day. The output of the charged battery reaches the controller or fencer or charger or energizer. When powered, the energizer produces a brief yet sharp voltage. The primary function of the energizer is to produce pulses of nearly 8000 volts that are sharp and short-lived. These pulses are passed through the wires of the fencing system at a rate of around 1 pulse every 1-1.5 second with every pulse lasting for nearly 3 ms, thus ensuring that no physical harm is caused to the intruder who attempts to come in contact with the solar fence
