Whether you’ve got a large farm on your hands, a brood of chickens, or a few acres of crop, keeping your land safe from predators and pests, or your livestock securely contained within their fields and pens, can be tricky and expensive – especially when you’ve got your electric fences powered by electricity from the grid. In fact, at times, powering your electric fence can seem an almost impossible task, if the field you’re looking to encircle is far from the nearest power source.

Thankfully, there’s an easy answer to questions of location, budget, and safety: a solar fence charger. Fitted with a solar panel, a solar charger is designed to power your electric fence and charge your battery during sunlight hours, so that your battery can run independently through the night. A solar fence charger can help cut costs dramatically in the long run, too. And if it seems confusing working out exactly which solar charger to buy for your specific needs, then fret not, this article is designed to help you make the best, most informed choice when shopping for the best solar fence chargers.

The Best Solar Fence Chargers In 2021

We’ve taken a look at our top picks from the market, but there are still many more options available to you, and many other elements you may need to consider. Here’s our top 7 solar fence chargers at a glance!

1. Zareba ESP5M-Z 5-Mile Solar Electric Fence Charger

  • Brand: Zareba
  • Seamless Mounting
  • Easy-Grip Terminals

Zareba’s 5 mile solar charger has a patented mount allowing for 360 degrees of rotation when mounted on a T-post, ensuring that wherever you need to place this fence charger, you can maximise its exposure to sunlight. What’s more, even if your land faces often over-clouded or rainy conditions, the ESP5M-Z can continue operating for 2 weeks without a charge (after a full charge).

Easy to install, this particular kit puts out 0.1 joules of shock power, and is to be used with up to 5 miles of steel wire, aluminium wire, polytape, polywire, or polyrope. It is best used for short-haired animals, including chickens, dogs, pigs, horses, sheep and cattle, but because of its lower output, has limited use against larger predators or livestock (such as moose, deer, bears, and bulls).

Fi-Shock ESP2M-FS 2-Mile Solar-Powered Electric Fence Charger

The Fi-Shock ESP2M-FS, built and tested in the USA, is a great addition to this list, and only narrowly missed out on our ‘Best for Small Animals’ top slot (thanks to a higher price point than the Zareba ESP2M-Z). Still, this is a nifty piece of kit. Super easy to install, the Fi-Shock comes with a 1-year limited warranty (including against lightning strikes), and is designed to work most effectively in the containment and prevention-to-access of small animals, including chickens, raccoons, foxes, skunks, possums, and rabbits.

With a 1-second pulsing shock of 0.04 joules, the Fi-Shock is also built with the health and safety of our furry friends and critters in mind, ensuring that whilst they’re kept out (or in), they’re not harmed in the process.

This kit from Premier 1 Supplies is probably the best all-rounder kit on the market, ideal for use with larger animals, and ready to install straight out of the box. The IntelliShock (named for the intelligent technology which regulates energy demand even when your fence is in constant contact with weeds – allowing for greater energy efficiency) comes with its own battery, and a clever mounted solar panel with 180 degrees of rotation. This means that wherever you choose/need to install your solar fence charger, you can ensure it gets all the sunlight it needs.

Furthermore, this kit comes with a grounding stake, and overcharge regulator, keeping you safe and your battery healthy.

Buyers Guide

There are lots of things to consider when looking to power your electric fence with solar power. Here are some of the most crucial questions you should be asking yourself.

Types of Animal

Depending on what types of animal you’re looking to contain (or keeping out), you’ll be needing a very different level of voltage. And it’s not always about size, either; short-haired large animals, like most cattle and horses, can often be contained with the same voltage required to contain medium-small sized animals, such as sheep, dogs, and pigs. Of course, the bigger your problem – bears in the orchard, say – the bigger the joules you’ll typically need. Zareba offer a really good chart on their products’ pages to help you assess the sort of power you’ll need depending on the animal.

Type of Fence Line

Consider as well what type of fence you’ll be charging with electricity. Most of the brands listed here work just fine with traditional steel or aluminium fence wire, as well as polywire, polyrope, or polytape. However, if you’re using polywire/tape/rope, then you can expect the power output of your solar electric fence charger to drop by as much as half. You should therefore plan your buy accordingly.

Weed Conditions

Again, most of the solar fence chargers on this list are designed with their own versions of low impedance technology, meaning that they can detect the contact of weeds on your fencing, and essentially ignore them, thus saving your fence’s energy only for when there is actual animal contact with the fence. Of course, some work better than others, and by-and-large the worse the weed conditions on your property, the harder your fence charger is going to have to work. Factor accordingly.

Length of Fence Required

This may seem an obvious one, but it’s arguably the most crucial thing to consider. After all, it would be of no use to find the perfect solar fence charger for your budget and animal considerations, and then receive it to find it covers way too little (or indeed way too much) fencing. Measure out the land, preferably in mileage, which you need your electric fence to cover, and factor this into your shopping. You may end up requiring a few of the same kits, or just one larger one.

Final Verdict

Taking into account price, length of fence charging, power output, brand reputation, and versatility, we have come to the conclusion that the best solar fence charger on the market has to be the Zareba ESP5M-Z 5-Mile Solar Low Impedance Electric Fence Charger. With a patented mount allowing for 360 degrees of rotation, a 5 mile power capability, and the power output necessary to be used with medium to large animals – not to mention Zareba’s 1 year warranty, and excellent consumer reputation – you can’t go very far wrong if you start out your renewable energy electric fence charging with this product.

FAQs

Is there any one-fits-all power output for all animals?

Unfortunately not. The logic behind this is fairly simple – if you’re looking to electrify a chicken coop, for example, you’ll want something gentle enough to keep your chickens contained and foxes kept out, whilst not hurting either animal. As such, you’ll need a low voltage/joule-output – in turn, this wouldn’t be strong enough to keep out (or in) larger animals, such as horses, cattle, bears or bigger. Still, there are some good solar fence chargers out there which do cover a wide range of animals.

How easy are solar fence chargers to install?

Thankfully for you, the answer is: very. The most integral part of installation for any of the chargers listed above, it would seem, is that before they are first installed, they must be charged for around 72 hours in sunlight. After this period, installing most of the solar panels on this list is as easy as grounding them, and plugging them into your fence.

What safety considerations do I need to make?

When working with (potentially very high voltage) electric fences, you must ensure you are sensible, and follow all safety precautions possible. Do not put your head or upper spine anywhere near an electrified fence; never encourage anyone (including yourself) to touch an electric fence; make sure the power to your fence is switched off before working on it; make sure it is properly maintained. Wear appropriate clothing and gear, and if worried, contact a professional engineer to help you install it.

How do I maintain my solar electric fence charger?

One of the best things you can do to ensure the longevity of your solar fence charger, and to maximise the power output from your solar fence charger, is to keep your fence free as possible from weeds and brush. Regularly remove debris from the fence area, as well as from the solar panel of your fence chargers, to ensure it is exposed to maximum sunlight. Lastly, monitor the performance of your solar fence charger by checking its indicator light, and keeping it turned toward the sun.
