6 Best Solar Charging Collars For Off Grid Farms That Keep Your Herd Safe
Explore the best solar-powered GPS collars for off-grid farms. These devices offer reliable tracking to keep your herd safe without grid dependency.
We’ve all had that sinking feeling in the pit of our stomach. You do a head count in the back pasture and come up one short. That’s when the frantic search begins, wasting hours you don’t have and filling your mind with worst-case scenarios. For those of us with remote or unfenced pastures, keeping track of the herd is a constant, low-level stressor.

Solar GPS Collars: Off-Grid Herd Security
Solar-powered GPS collars are a game-changer for the modern small-scale farm. They solve the biggest problem with traditional trackers: dead batteries. Out in a 40-acre pasture, you can’t exactly run out to swap batteries every few weeks. Solar panels on the collar trickle-charge the battery, ensuring it’s always ready to report its location.
This isn’t just about finding a lost animal. It’s about proactive management. You can see grazing patterns, identify an animal that has separated from the herd (often the first sign of illness or injury), and receive alerts if one wanders beyond a pre-set boundary. It’s peace of mind in a box, allowing you to manage your land and your time more effectively.
Nofence Collar: Virtual Fencing Without Wires
Nofence is more than just a tracker; it’s a complete virtual fencing system. You draw a boundary on a map on your phone, and the collars keep your animals inside it. There are no wires to install or maintain. This is revolutionary for rotational grazing on difficult terrain where running traditional fencing is impractical or impossible.
The system works through a series of escalating audio cues. As an animal approaches the virtual boundary, the collar emits a sound. If it continues, the sound gets more insistent, eventually followed by a mild electric pulse. Animals learn the audio cues quickly, often in just a few days, and learn to respect the invisible line.
The flexibility is incredible. You can move your pasture boundaries with a few taps on a screen, allowing you to manage grazing pressure perfectly. The major tradeoff is cost. Nofence is a significant investment, both in the price per collar and the monthly subscription. It also requires a herd that is trainable and a farmer willing to monitor the initial learning phase closely.
Barn-I Solar Tracker for Real-Time Location
If virtual fencing feels like overkill, the Barn-I Solar Tracker is a fantastic, straightforward solution. Its primary job is to tell you one thing: where your animal is, right now. This collar is built for reliability and simplicity, with a robust solar panel that keeps the unit powered in all but the darkest winter months.
This is the perfect tool for monitoring herds in large, securely fenced areas or for keeping tabs on a lead animal. You get location history, movement alerts, and a simple interface without the complexity or cost of a virtual fencing system. Think of it as a pure security device. If a predator scatters your flock or a gate is left open, you’ll know exactly where to start your search.
FindMySheep Collar: Built for Remote Pastures
The name says it all. The FindMySheep system was developed in Norway for tracking sheep across vast, rugged, and remote landscapes with spotty or non-existent cell service. This is a system designed for true off-grid conditions. It often utilizes long-range, low-power networks (like LoRaWAN) instead of standard cellular data, giving it incredible reach.
These collars are lightweight, durable, and engineered for maximum battery longevity. The updates might not be as frequent as some cellular models—sometimes just a few times a day—but that’s a deliberate tradeoff for ensuring the battery lasts through long, dark winters or in deep, shaded valleys. If your farm includes wooded hills or remote acreage far from a cell tower, this is the kind of specialized tool you need.
Tractive GPS XL: A Versatile Livestock Option
Track your dog in real-time with this GPS tracker, featuring unlimited range and location updates every 2-3 seconds. Set virtual fences and receive health alerts for unusual activity, ensuring your pet's safety and well-being.
Tractive is a huge name in the pet tracking world, and their XL model bridges the gap into livestock. It’s a solid, budget-friendly option for smaller animals like goats, sheep, alpacas, or even a donkey. It offers the core features you need: live tracking, location history, and virtual fence alerts that ping your phone if an animal leaves a designated area.
The main advantage here is accessibility and cost. Tractive collars are less expensive upfront, and their subscription plans are very competitive. The tradeoff is in durability. While the XL is water-resistant and fairly tough, it wasn’t designed for the same level of abuse as a dedicated agricultural collar meant for a 1,500-pound steer. For a small flock of well-behaved sheep or goats, it’s an excellent entry point into GPS tracking.
BoarMaster Solar: Rugged Tracking for Any Animal
Don’t let the name fool you; this collar is for much more than wild boar. Originally designed to withstand the incredibly harsh life of a wild pig, the BoarMaster is one of the most durable solar trackers on the market. The housing is thick, the solar panel is well-protected, and the collar material is built to resist tearing and chewing.
If you have animals that are notoriously hard on equipment—think bulls, livestock guardian dogs, or particularly mischievous goats that love to rub on trees—this is your collar. It provides reliable GPS tracking with a focus on survival. The extra durability means it’s heavier and bulkier than other options, so it’s best suited for larger, more robust animals.
Agri-EID Solar Tag: A Lightweight Alternative
For those who manage larger herds or prefer a less intrusive option, the solar-powered ear tag from Agri-EID is worth a look. Instead of a bulky collar, this device is a lightweight tag that provides the same core function: solar-powered location tracking. This is a great way to monitor the location of every animal in the herd, not just a few.
The primary benefit is the form factor. It’s less likely to get snagged on brush than a collar and is a "set and forget" solution. The main downsides are that ear tags can be torn out, and the smaller solar panel and battery mean you might get less frequent location updates compared to a full-sized collar. It represents a different approach, prioritizing herd-wide data over the high-frequency tracking of a single animal.
Choosing Your Collar: Key Features to Consider
Picking the right collar comes down to your specific animals, property, and goals. There is no single "best" option, only the best fit for your farm. Before you buy, think through these key factors.
First, consider the function. Do you need virtual fencing to control grazing, or do you just need location tracking for security? A system like Nofence is a powerful management tool but comes at a premium. A simple tracker like Barn-I or Tractive provides peace of mind for a fraction of the cost. Your answer to this one question will narrow the field considerably.
Next, look at your environment and your animals.
- Connectivity: Do you have reliable cell service in your farthest pasture? If not, you’ll need a satellite or LoRaWAN-based system like FindMySheep.
- Durability: Are your animals calm grazers or rough-and-tumble escape artists? Be honest about how much abuse the hardware needs to withstand.
- Solar & Battery: How much direct sun does your property get, especially in winter? A highly efficient solar panel and large battery are critical in cloudy or northern climates.
- Cost: Don’t just look at the upfront price of the collar. Factor in the monthly or annual subscription fees, which can vary dramatically between services.
Ultimately, the right collar is the one that solves your biggest problem. Whether that’s preventing escapes, simplifying rotational grazing, or just getting a good night’s sleep knowing your herd is safe, the technology is finally here to help.
This technology isn’t a replacement for good fences and daily observation, but it is an incredibly powerful tool. It allows us to manage our animals more humanely and our land more effectively. By choosing the right collar for your needs, you can reclaim your time and gain the confidence that your herd is safe, even when you’re not there.
