SOLAR FENCING SYSTEM
Solar fence system enables the control of animals by giving them a short, sharp but safe Shock,
which is sufficiently memorable that they never forget it. Solar fence has the capacity to Power long distances
of multi wire fences. This has promoted the use of electric fencing on to large properties and enabled the
control of all animals, including wild ones.
Solar fencing need not have physical strength because it seldom comes under pressure but it must
be well designed and constructed to absorb the impact of animals.
WHY GO FOR SOLAR POWER FENCING?
Keep animals, including wild and vermin, away.
Growing, rationing of crops and pastures can be
improved during slow growth periods.
Separate various types and classes of animals.
Fence off trees, rivers, eroding areas and roads
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 / 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.
The Energizer has to be set up with its earth terminal coupled to an adequate earthing or
grounding system. The live terminal is coupled to the live insulated wires of the fence. Energizer will send an
electric current along an insulated steel wire. An animal or intruder touching the live wire creates a path for
the electrical current through its body to the ground and back to the Energizer via the earth or ground system,
thus completing the circuit. The greater the shock the animal receives the more lasting the memory will be
and the more the fence will be avoided in the future. The shock felt is a combination of fence voltage and
pulses time or energy. The higher the *joule rating of the energizer the greater the shock and the greater the
fence performance.
*JOULE: Unit of energy. One joule is one watt for one second. It is an important measure of the power of an
Energizer.
The basic building blocks of a power fence are:
1. Energizer
2. Earthing (Grounding System) and
3. Fence system
ENERGIZER:
The heart of the Power fence is the Energizer. The energizer is selected depending on the
animals to be controls, 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
from battery. The energizer should be protected from children, should be enclosed, free from mechanical
damage and away from inflammable material.
EARTHING SYSTEM:
The earth or ground system of the Energizer is like the antenna or aerial of a radio. A large radio requires a
large antenna to effectively collect sound waves and a high powered Energizer requires a large number of
electrons from the soil.
The earth or ground system must be perfect to enable the pulse to complete its circuit and give the animal an
effective shock. Soil is not a good conductor so the electrons spread out and travel over a wide area, inclining
towards moist mineral soils. If possible, select an area for the energizer earth site which is damp all the year.
A Power Guard solar panel (a photovoltaic panel) converts sunlight into electrical energy and this is used
to charge up a battery. The battery collects energy when the sun is shining and stores it until it is
needed to power a fence.
Suggested Wire Spacings Some of the possible wire spacings for permanent electrical fences are shown below
Do's and Don'ts
Do's: Keep your fence neat and clean.
Maintain the wire tension regularly.
Water your fence earth system periodically.
Maintain your battery properly.
Do remove Energizer connections during heavy storms (likely to lightening).
Always use proper fence tools during maintenance.
Don'Ts: Do not connect AC mains power to the Energizer and to the fence lines.
Do not power the Energizer directly from the charger or from the solar panel.
Do not over extend your fence
Never use household electrical cable.
Never use copper wire undergate cable because electrolysis problems occur where it is
joined to the galvanized fencing wire.
Never electrify barbed wire. It is dangerous, has the potential to cause faults and is illegal in some
countries.
Features:
Easy Construction.
Power fence can be erected to target species only.
Low maintenance.
Long lasting because of minimal physical pressure.
All domestic and wild animals can be controlled economically.
Makes strip grazing and back fencing easy.
Encourages additional subdivision, giving increased production.
Modification of system to control a variety of animals is very easy.
Aesthetically pleasing.
Discourages trespassers and predators.
Not harmful. It gives a short, sharp but safe shock to the intruder.
