How PV Cells Produce Electricity
Solar Fencing System
----------------------

Solar Fencing is the modern day`s alternative to the conventional type of perimeter protection. These are helpful in providing security against unauthorized access of humans and animals. This solar fence provides a short and sharp shock for enhancing good security.Against any tampering the alarm incorporated in the system gets activated and alerts the inmates of the protected area, which facilitates them to counter the unwelcome intruders. The solar fence is scientific fence and works on Solar Energy with backup facility to run uninterruptedly during the nights as well as cloudy days.

The basic components of a power fence are:

1. Solar panel
2. Battery
3. Energizer
4. Earthing (Grounding System) and
5. Fence system


Working Diagram of Solar Fencing

1. Solar panel:

Solar panel acts simply as a battery charger. It converts the sunlight directly in to DC current. A panel of 12 V/ 35 W capacity was used to change the 12 V/ 100 AH (Plate 1). The size of the solar panel depends upon the energizer size, power setting, geographical locations, level of usage, full year, and summer or spring and autumn.

2. Battery:

Battery acts as energy storage device (12 V/100AH). It stores the electricity generated by the solar panel, which allows the energizer to operate at night or during cloudy days.

3. Energizer:

The heart of the Power fence is the Energizer. The energizer is selected depending on the animals to be control, length of the fence and number of strands. Main function of the energizer is to produce short and sharp pulses of about 8000 volts at regular intervals. The power input is from the DC energy battery. The energizer should be protected from children should be enclosed free from mechanical damage and away from inflammable material.

5. Fence Wire Systems:

There are two types of fence wire system, they are, all Live Wire System and Earth or Ground Wire Return System. The 2.5 mm (12.5 gauge) High Tensile (H.T) Fence wire is recommended for electric fence systems because of its advantages:

• It retains its tension far longer than soft wire.
• It conducts sufficient current for most applications.
• It is reasonable visible.
• High Conductive Aluminium Coated Wire is best used for long lead-out i.e. several kilometres.
• Double insulated Lead-out Cable is used in building, under gateways and where the soil could corrode exposed galvanized wire.


Solar Power Electric Fence Energizer
Working principle:

The Solar module generates the DC energy and charges the Battery. The output of the battery is connected to Energizer or Controller or Charger or Fencer. The energizer will produce a short, high voltage pulse at regular rate of one pulse per second. The live wire of the energizer is connected to the fence wire and the earth terminal to the Earth system. Animal or intruder touching the live wire creates a path for the current through its body to the ground and back to the energizer via the earth system and completes the circuit. Thus the intruder will receive a shock. The greater the shock the intruder receives the more lasting the memory will be avoided in future.
