Electric fence is a psychological barrier that keeps animals in and wild animals and predators out. A pulse of electric current is sent along the fence wire, about one pulse per second, from an energizer which is grounded. When the animal touches the fence, it completes the circuit between the fence and the ground and receives a short, sharp but safe shock. The shock is sufficiently memorable that the animal never forgets.
Because it is a psychological barrier, it does not require great physical strength. However, it must be well designed and constructed to absorb some pressure from animals, snow and wind. The energizer must have enough power for the length of the fence and for the animals being controlled.
Solar Power Electric fence have been installed by Suryodaya Urja in Bardia National Park, which is covering an area of 968 km2 , to prevent from predator attack and wildlife management. Battery-powered and solar-powered energizers offer effective animal control for remote locations where power is unavailable. Solar-Powered Energizers are the logical choice for remote areas where there is no available power. A solar panel charges a battery by converting sunlight into electricity to keep the energizer operating day, night or during low sunlight periods.
