Benefits of a Solar Energizer

Like an AC electric fence, a solar-powered (DC) electric fence can be used to keep livestock and pets safe and secure or wildlife and pests out. Unlike an AC fence charger, a solar fence charger uses a small solar photovoltaic (PV) panel to collect and convert sunlight into energy, which is then stored in the battery so that it can electrify the fence.

A solar unit is great for rotational grazing and remote applications, which is why more and more people are becoming interested. It can power long lengths of fence without constantly recharging and replacing batteries.  Solar fence chargers need little safeguarding and can work with existing fencing systems. Solar panels can produce enough energy under cloudy conditions so the battery can provide power to the energizer for up to 10 days.

Benefits:

  • Eliminates the need to constantly change out batteries
  • All-in-one systems are available that combine energizers and a panel or a panel can be purchased to fit DC energizers
  • Portability makes them great for rotational or strip grazing
  • Easy to find
  • Perfect for remote, off the grid areas
  • Affordable
  • No need to worry about power outages
  • Solar is an environmentally friendly, renewable resource

Key components:

  • Energizer – must be a DC unit and must be large enough for the fence line (approximately 1 joule per mile of fence line)
  • Battery – 12-volt deep-cycle marine battery (80-120 amp hour)
  • Charge controller with low-voltage disconnect
  • Grounding
  • Solar panel – size of the panel will depend on the energizer size (10 watts of panel per joule of energizer)
  • Geographic location
  • Usage level and season of the year

The benefit to a solar fence charger is that it keeps animals from escaping and protects valuable livestock, pets, and property. All you need is sunshine, but be cautious! PeakSunlightHoursMap1The solar panel should
receive adequate sunlight hours. As the seasons change, so does the direction and amount of sunlight.
