What To Look For in a Solar Powered Electric Fence

There are plenty of features that impact how well a solar-powered electric fence performs, and you’ll want to make sure you find the perfect specifications to meet your own needs. Let’s take a look at some of the main areas of focus when considering which charger is right for you.

Energy output (Voltage & Joule)

The amount of power emitted by the solar electric fence charger is measured in voltage and joules. The higher the voltage and joule output, the more powerful of a shock will be delivered. You want to be sure to check the minimum requirements for different kinds of pets and livestock. The larger the animal, the more likely it is you’ll need a high voltage output.

For instance, the minimum voltage required for cows and horses is 3,000 - 4,000 volts, while poultry and pets range from 500 - 1000 volts.

Coverage Area

solar fencer charger for large area

Owners of smaller farms and gardens should have no problem finding a solar electric fence charger that meets their needs.
However, those searching for large area coverage should look for a charger with a high joule output. This will allow a more powerful shock to be administered over longer portions of fencing.

Our list of the Best Solar Fence Chargers contains coverage areas ranging from 3 miles of charged fence all the way up to 30 miles.

The solar electric fence chargers on our list are considered low impedance chargers. Compared to high impedance chargers, low impedance models provide short pulses of electric current with little resistance.

electric fence warning sign

This results in more powerful shocks, but adds a level of safety, seeing as there is not a continuous current traveling through the wires.

Low impedance solar fence chargers also allow the fence to keep its charge even in areas of tall weeds and vegetation, leading to less battery drainage. Though the overall power might be slightly reduced when weeds are present, it’s unlikely to cause major disruption.

Fence compatibility

electric fence type

Depending on what type of fence you’re looking to energize, different solar fence chargers may be better than others. In general, steel wire usually performs best.

While many chargers on our list are compatible with a variety of fences, including aluminum, high tensile steel, polywire, polyrope, or polytape, it’s important to note that different fencing materials may impact the maximum power output.

Animal size

Referenced White Mountain Miniatures

Certain animals require higher voltage and joule output, so choosing the correct model for your needs is important. You wouldn’t want to contain horses and cattle with a charger that’s meant for pets, as it would not provide enough of a shock to keep the animals within the desired boundaries.

That being said, using too powerful of a solar powered fence charger for more casual home or garden needs may also not be necessary. Our list should offer some clarity as to which charger is best for each scenario.


Solar-powered fence chargers are meant to be left outdoors for prolonged periods of time. When choosing a charger you want to be sure that they are designed to resist water, snow, hail, etc.

Having a fully waterproof design ensures that the charger won’t succumb to the elements.
Durability is a major aspect of choosing the right solar fence charger, and our list contains some of the most durable on the market.

Mounting Points

electric fence installation and mounting

When mounting solar powered fence chargers, it's best to place them in locations with little obstruction from the sun. Areas away from trees or shaded buildings will provide the clearest access point to the sun’s rays.

The type of mount can also factor into the effectiveness of the charger. Many of our previously listed chargers can be easily mounted to a variety of points such as rounded fence posts, flat wall surfaces, y-posts, and t-posts.

As mentioned in the review of the Zareba chargers, mounting on a t-post allows for added versatility when adjusting the solar fence charger to face the sun.

Solar Panel Quality

As with any product, quality counts. Choosing solar electric fence charges with high quality solar panels will help in the long run, providing more efficient power and less degradation.

It’s also important to make sure that your solar panels stay relatively clean from dirt and debris so that their effectiveness isn’t impeded in any way.

How Does a Solar Fence Work?

how solar fence charger works

Referenced Matthew T. Stallbaumer and Jeffrey R. Yago.


dog sitting behind electric fence

Solar fences work by harnessing the sun’s energy and converting it into electricity. This energy can be stored within a battery and used to power the fence at times when sunlight isn’t readily available.

Solar electric fence chargers used at home operate in the same way as longer range models, though usually produce less powerful shocks with a lower voltage and joule output.

Solar electric fences designed for home use work well to contain pets like dogs, rabbits, and other small animals. These shocks are essentially designed to create a psychological boundary so that the animals will learn not to cross.


solar electric fence protecting garden plants

Much like home use, solar-powered fence chargers that are suitable for gardens provide slightly less powerful shocks, but still are able to protect gardens from rabbits, deer, and other animals looking to make a meal out of your crops.

Using a solar-powered fence charger as a garden deterrent can be a very cost-effective method of pest control.

Specific controlled environment

protect live stock from wild animal solar electric fence

For ranchers and farmers in search of temporary grazing solutions, or anyone in need of animal containment in remote areas, solar powered fence chargers work off-grid and can provide the security desired in these types of environments.

Though low impedance technology allows the chargers to function in the presence of weeds, it’s always best to have a clean area surrounding the fence to ensure maximum delivery.

Common FAQ

How many joules should a fence charger have?

The exact amount of joules needed depends mainly on the type of animals you’re looking to contain or deter, as well as the overall mileage or acreage of the property.

Our list of the Best Solar Fence Chargers features products with joule outputs ranging from .04 to 3.1. A larger containment area with larger livestock will require more joules.

How many joules is dangerous?

In order to avoid any bodily harm, standard safety measures have been implemented to cap the joule output of a solar electric fence shock at 5 joules.

How many joules does it take to stop a heart?

It’s difficult to determine an exact number of joules that it takes to stop a human heart, but under 5 joules is considered safe, while greater than 10 joules is considered hazardous. All the solar-powered fence chargers on our list fall within the safe range.

How long do solar fence chargers last?

Depending on the model and battery size, solar fence chargers can continue to operate without sun for up to 3 weeks. The battery itself may need to be replaced every 3 to 4 years, but the solar panel should provide the needed energy for years to come. With warranties of up to 5 years, these chargers are long-lasting investments.

Can I use this for dogs?

Most solar electric fence chargers are safe to use with dogs, though it is always a good idea to check the voltage and joule output. Minimum voltage requirements for pets range from 700 - 1000.

What direction should a solar fence charger face?

In the northern hemisphere, solar powered fence chargers should generally face the south in an area with minimal covering and a clear view of the sun. Depending on what type of mount is used, chargers can be rotated to follow the sun as needed.
Can you put two fence chargers on one fence?
