Management and Challenges of Solar-Powered Electric Fencing
By Jaclyn Krymowski.
Electric fencing may be one of the biggest innovations in livestock handling since barbed wire. With better reliability, affordability and, thanks to enhanced solar batteries, more effective range and mobility, we are living in a global era of portable and permanent fencing.
Beyond keeping animals in, electric fencing has also offered a powerful boon to keep predators out in a way that is far more effective than traditional woven wire and even high tensile options.
As battles over land usage continue to rage across the states and more cattlemen are forced to look at other options to move and graze cattle, it is essential to understand the options that electric fences offer. As with any permanent or portable system, this system will only be effective when it is well-managed.
About Electric Fences
Contrary to popular belief, the use of electric fencing dates back to the 1930s, with even earlier applications during World War I. However, its widespread adoption was hindered by the unreliable electricity infrastructure in rural America at the time. The breakthrough came with the expansion of the power grid, the development of insulators using materials like polyethylene plastic, and the increased availability of high-tensile steel. This confluence of factors catapulted electric fencing into the mainstream, making it more affordable and accessible.
One key factor contributing to affordability is the reduced need for heavy, well-anchored posts, as electric fencing relies on the deterrent of electric shocks rather than physical barriers. This shift has not only reduced costs but also increased the efficiency of installation, making it a viable option for various applications.
Contemporary electric fencing operates on a simple circuit, maintaining a continuous low voltage. When an animal comes into contact with the fence, it receives a sharp jolt, serving as a deterrent. Voltage recommendations vary based on the target animals. For beef cattle, a starting range of 2,000-3,000 volts is suggested. Deterring predators may require higher voltages, around 5,000 volts, as recommended by retailers like Valley Farm Supply.
Management with Solar Energy
Solar energy has revolutionized the efficiency and sustainability of electric fencing. Solar-powered electric fences and solar generator systems are two prominent options for ranchers looking to reduce operational costs and enhance the reliability of their electric fencing.
Solar-powered electric fences directly link into solar panels, converting captured solar energy into electrical current. These systems offer a direct and consistent power source, minimizing reliance on conventional electricity grids.
On the other hand, solar generator systems convert solar energy into electricity stored in batteries. This provides ranchers the flexibility to operate in remote locations or off-grid pastures, ensuring continuous power supply even in challenging environmental conditions.
The maintenance of solar electric fence systems is remarkably low. Routine checks on the cleanliness of panels and voltage output are typically sufficient to ensure their longevity. Moreover, the diverse range of battery units available allows for prolonged operation, even during low-light periods or adverse weather conditions.
A solar generator system converts solar energy into electricity, which can then be stored in batteries. A solar generator system allows ranchers to use them in remote locations or off-grid pastures.
Regardless of the scale or permanence of the electric fence system, certain fundamental upkeep needs must be addressed:
Unobstructed Wires: Regular checks for potential obstructions, such as fallen trees or overgrown brush, are crucial to preventing system short-outs and voltage reduction. The use of a fault finder during routine inspections can confirm if the system is delivering the expected voltage.
Equipment Maintenance: Ensuring the power source and batteries (in portable systems) are in optimal condition is essential. Many retailers offer warranties and troubleshooting resources to help ranchers maintain their electric fence systems.
Grounding System Inspection: An often-overlooked aspect of electric fence maintenance is the grounding system. Poor grounding can significantly diminish the effectiveness of the electric shock that is delivered to animals or predators. Ranchers should periodically inspect grounding rods and connections to ensure they are free from corrosion and securely placed in moist soil. Proper grounding is vital for the efficient functioning of the electric fence system.
Vegetation Management: Beyond addressing immediate obstructions, ongoing vegetation management is crucial for the sustained effectiveness of electric fencing. Tall grasses or climbing vines can create a bridge for electric currents, potentially grounding the fence or diminishing its voltage. Regular trimming or clearing of vegetation along the fence line is necessary to prevent such interference and maintain optimal performance.
Weatherproofing Components: Exposure to the elements can impact the longevity of electric fence components. Check insulators, connectors, and wiring for signs of wear or damage caused by weather conditions. Applying weather-resistant coatings or utilizing UV-resistant materials can extend the lifespan of these components, ensuring the electric fence remains reliable in various weather conditions.
Affordability and Long-Term Cost-Effectiveness
Solar-powered electric fences stand out for their affordability and long term cost-effectiveness. With low operating costs, these systems become economically viable over time, especially when compared to traditional electric fences that rely on external electricity or fuel sources. The absence of ongoing energy expenses contributes to significant savings for ranchers.
Drawbacks and Limitations
One potential drawback of solar-powered electric fences, particularly those relying solely on direct solar energy and other limited battery storage, is their susceptibility to poor weather conditions. In instances of prolonged cloudy days or inclement weather, the system may experience reduced efficiency or temporary lapses in functionality. This limitation underscores the importance of carefully considering local weather patterns and assessing the system’s ability to cope with adverse conditions.
While the initial cost of installing a solar generator may pose a hurdle, the long-term running costs are lower. The ongoing savings on energy bills, coupled with the environmental benefits of reduced carbon footprint, make solar generators a compelling investment for environmentally conscious ranchers.
Managing electric fences with solar power presents a compelling option, balancing affordability, sustainability, and independence from external power sources. Despite potential drawbacks related to weather conditions, the benefits of reduced operating costs and environmental impact make solar-powered electric fences a worthwhile investment.
It’s crucial for ranchers to weigh the pros and cons, considering factors such as local weather patterns, terrain, and budget constraints. While solar-powered electric fences don’t need to be overly complicated, understanding the specific needs of your setup will allow you to maximize the system’s efficiency and extend its benefits.
