Whether you’re trying to keep your animals in or keep unwanted animals out, they always seem to find a way into places that they don’t belong. One of the simplest and most effective ways to keep animals where they should be is a quality electric fence. Electric fencing is designed to give off a tiny shock whenever touched by a person or animal. These shocks are not harmful, but they are an effective way to warn an animal that they have gone too far and should turn back. You could install an electric fence that runs on AC power, but why pay to power your electric fence when you could use free eco-friendly solar power?

Solar electric fence chargers use small solar panels to charge an internal battery that in turn provides electricity for your electric fence. Not only are these chargers simple to install, but they are also free to run, making them even more user-friendly. Several companies make these chargers so to save you some time, we did a bit of research and compiled a list of some of the best chargers out there. After checking out our product picks, you can read on for some helpful information that will help you to choose the best solar electric fence charger for you.

How We Chose The Best Solar Electric Fence Chargers

Long-term manufacturer warranties are also a positive sign, showing that these companies fully support the quality of their products.

The easier the installation the less likely you are to encounter any safety issues. All of the chargers on our list come with easy to follow set-up instructions, obvious on/off switches, and power indicator lights. Each of these features will assist you in a safe and worry-free installation process.

What You Need To Know About Solar Electric Fences

If you’re new to the world of solar-powered electric fencing, there are a few key things you should know before you get started.

Accessories Not Included

Most solar electric fence chargers do not come with any fencing materials, they are sold individually. This means that you will have to buy all the accessories required for installation. These materials may include things like:

  • Fence Posts
  • Post Insulators
  • Grounding Post
  • Grounding Clamp
  • Electric Fencing Wire or Tape
  • Insulated Handle
  • Voltage Tester

The number of materials that you need will depend on whether you’re installing a brand new fence or just electrifying an existing fence. Just be aware that unless you’re purchasing a kit, like the one we featured from Zareba, you’ll have to buy all your accessories separately.

Stay Grounded

This is probably one of the most important things to remember about installing an electric fence. You absolutely must ensure that the fence charger is properly grounded. Electricity always travels in a circuit. If you do not have a properly installed grounding rod, the electricity will not have anywhere to travel, meaning whatever touched the wire will not receive a shock.

To ensure that your electric fence is properly shocking, a grounding rod must be installed. A good quality grounding rod should be at least 6’ tall and should be made out of galvanized steel or copper. This rod must be driven into the ground as deep as you can get it, leaving only a few inches exposed. Use a grounding clamp to attach the grounding wire from your charger to the grounding rod and you should be good to go. If you have a larger fence you may have to install multiple grounding rods for it to work properly. Remember to keep all grounding rods away from existing water lines, electrical lines, or phone lines.

Cleanliness Is Next To Efficiency

Solar electric fence chargers require very little maintenance, but your fence itself will involve some work. If your fence is properly electrified, it should be giving off small electric charges every time it is touched. This includes when it is being touched by brush and weeds. Anything touching your fence can seep power away from it and weaken the battery, meaning that it will not function properly. To avoid this problem you should make sure that nothing is touching your electrified wires because even something as seemingly insignificant as tall grass can decrease the efficiency.

How to Choose The Best Solar Electric Fence Charger For You

Now that you know all about solar electric fence chargers it is time to determine which one will be the best for you. This is a pretty simple process that just requires a little bit of forethought.

Know Your Area

The first step is to determine what size area you want to surround. You can do this in several ways. You could simply use a measuring tape if the area is small enough or you could walk around the area using the GPS tracker on your phone to track how far you’ve walked. Once you know how big the area’s parameter is, you can then determine how much wire you need to energize.

Remember, the power range given in the specifications is usually for a single wire. This means that a charger capable of powering 20 miles of wire can only power 10 miles of fencing if you plan on having two electrified wires on the fence. If you want to have three electrified wires you would have to divide that number by three and so on. If you are fencing in a large area, you will probably want to purchase multiple chargers to ensure that they can produce enough power.

Know Your Animals

The second thing that you need to know is what type of animals you’re trying to control. This will help to determine how powerful the fence needs to be. If you’re just trying to protect your garden from rabbits and other small creatures, then a smaller charger should be sufficient. If you’re using the fence to contain your livestock, then you’ll want to choose something with a little more juice. Thankfully, most solar electric fence chargers come with a guide on them to show you the type of animals that they are meant to repel, making this part of the process pretty straightforward.

Bottom Line

Electric fences are one of the easiest and most efficient ways to contain your livestock or protect your land from unwanted animals. With a solar electric fence charger, you can install an electric fence anywhere on your property without having to run new wiring or waste money on extra energy bills. Solar chargers are simple to install and even easier to maintain, making them the perfect choice for temporary pastures and rotational grazing.

Though you can’t go wrong with any of our top 5 solar electric fence chargers, we recommend the Parmak Solar Pak 6 Fence Charger as the best overall choice.
