There are no upfront costs prior to installing an electric fence. The customer must provide a structurally sound “outer” perimeter fence — something already present on most potential sites. We own and service all essential materials in The Electric Guard Dog Fence. Operating costs are negligible because The Electric Guard Dog Fence is powered by a 12-volt marine (DC) battery continuously charged by a solar panel(s). Traditional power sources (the grid) may be used as a backup measure or to assist in (trickle) charging the battery — options that would not noticeably increase energy costs.
