6 Best Solar Powered Waterers For Remote Horse Paddocks That Work Year-Round
Reliable, ice-free water for remote horse paddocks. Discover the top 6 solar-powered waterers that work year-round, no electricity required.
Hauling water in five-gallon buckets to a remote back pasture gets old fast, especially in the dead of winter or the peak of summer. The constant worry about a trough running dry or freezing solid is a burden no one needs. A reliable, automated watering system isn’t a luxury; it’s a fundamental tool for sane and sustainable animal management.

Why Solar Power is Key for Remote Pastures
The biggest hurdle with a back paddock is often the lack of infrastructure. Running electricity and water lines hundreds of yards, or even a quarter-mile, is prohibitively expensive and disruptive. You’re talking about trenching, permits, and a hefty bill from the utility company just to power a simple pump or a de-icer.
Solar power completely sidesteps this problem. It offers true independence. By harnessing the sun, you can place a water source exactly where your animals need it most, not just where the grid happens to reach. This allows for better rotational grazing and pasture management, as you’re no longer tethered to the barn.
Modern solar setups are surprisingly resilient and affordable. The technology has improved dramatically, with efficient panels, durable pumps, and smart controllers that manage power effectively. For a one-time investment, you get a self-sufficient system that works silently in the background, providing clean water year-round with minimal maintenance.
RPS Solar Pumps: A Robust Well-to-Trough Kit
When you have a well drilled in a remote pasture but no power, a complete kit is often the simplest path forward. RPS Solar Pumps has built a reputation on providing comprehensive, well-matched systems designed for exactly this scenario. Their kits typically include the submersible pump, solar panels, and a controller that manages the whole operation.
The beauty of a kit like this is that the components are already sized to work together. You’re not guessing if your panel is powerful enough for your pump. This is a workhorse system designed to move significant water from a well to a large stock tank. It’s ideal for a small herd of horses or cattle where daily water demand is consistent.
For year-round use, you’ll still need to address freezing. While the pump itself is protected down in the well, the trough is vulnerable. The RPS system provides the power infrastructure; you can then add a separate, solar-compatible 12V or 24V de-icer to the trough, often powered by the same battery bank that runs the pump on cloudy days.
Solar Trough: The All-in-One Watering Solution
For ultimate simplicity and portability, the all-in-one solar trough is hard to beat. These units integrate a small solar panel, a battery, and a pump directly into the design of the waterer itself. You simply fill the main reservoir, and the system automatically keeps a small drinking basin full for the animals, often with a float valve.
Their main advantage is mobility. You can move the entire unit from one paddock to another as you rotate your horses. This makes them perfect for temporary grazing areas or for farmers who need maximum flexibility. They are self-contained and require virtually no setup beyond an initial fill.
However, there are tradeoffs. These units typically have a smaller water capacity and less powerful solar arrays compared to component-based systems. In regions with many cloudy winter days, the small integrated panel and battery might struggle to keep up, especially if it includes a heating element. They are an excellent solution for milder climates or smaller herds, but may not be robust enough for a harsh northern winter without careful management.
The DIY Solar Kit: K&H De-Icer and Bilge Pump
If you’re comfortable with some basic wiring, a DIY setup offers the most customization and can be incredibly cost-effective. The core of this system is a simple 12V marine bilge pump. These pumps are cheap, durable, and designed to sit submerged in water, making them perfect for dropping into a nearby creek, pond, or a large cistern you fill periodically.
To power it, you’ll need a few key components:
- A solar panel (a 100-watt panel is a great starting point).
- A charge controller to protect the battery from overcharging.
- A deep-cycle marine battery to store power for cloudy days.
- A float switch to turn the pump on and off automatically as the trough water level changes.
The real magic for year-round use comes from adding a separate, efficient de-icer. The K&H Ultimate Stock Tank De-Icer is a popular choice that comes with a thermostat to only run when needed, saving precious battery power. You can run both the pump and de-icer off the same battery, but you’ll need to size your panel and battery bank accordingly to handle the combined load, especially during short winter days.
This DIY approach lets you build a system perfectly tailored to your needs. You can start small and add more panel or battery capacity later. It requires more planning but gives you full control and a deeper understanding of your system.
Sun-Mar Solar Systems for High-Capacity Needs
Sometimes, a small-scale solution just won’t cut it. If you’re managing a larger herd, multiple pastures, or need to pump water over a significant distance, you’ll need a more powerful system. Sun-Mar and similar brands offer high-capacity solar water pumping systems designed for more demanding agricultural use.
These systems feature larger, more efficient pumps and are paired with multiple solar panels wired together for higher voltage and wattage. This allows them to move more gallons per minute and push water uphill with greater force. They are a significant step up from a simple bilge pump or an all-in-one trough, both in performance and in price. Think of this as the solution for servicing a central, large water tank that then gravity-feeds multiple troughs.
Solar-Stream Pump for Deep Well Applications
Not all wells are created equal. A shallow well might only be 20 feet deep, but a drilled well in a dry area could be hundreds of feet deep. A standard solar pump won’t have the power to lift water from that depth. This is where specialized deep-well pumps like Solar-Stream come into play.
These pumps are engineered specifically to overcome high "head," which is the vertical distance they have to lift the water. They are typically more expensive but are the only viable option for deep wells. When choosing one, the manufacturer will have clear charts showing how many gallons per minute it can pump based on the well’s depth. Ignoring this specification is a recipe for a failed system.
Agridrink Solar Pump with Tuff Stuff Tank
A great system is often about pairing the right components. Combining a reliable, purpose-built solar pump like those from Agridrink with an industry-standard, durable stock tank like the Tuff Stuff brand creates a fantastic semi-permanent watering station. The pump can be placed in a nearby pond or cistern, with the hose running to the tank.
The Agridrink pumps are often designed with livestock in mind, featuring built-in float switches and durable, non-corrosive housings. Pairing this smart technology with a nearly indestructible, UV-resistant Tuff Stuff tank means you have a setup that can withstand years of abuse from both animals and the elements. This modular approach lets you replace a single component if it ever fails, rather than the entire system.
Sizing Your Solar Panel, Pump, and Battery
Getting the sizing right is the single most important factor for a reliable year-round system. An undersized system will fail you on the third cloudy day in a row in December, right when you need it most. A grossly oversized one is a waste of money.
First, calculate your daily water demand. A horse drinks roughly 10 gallons per day, so a four-horse pasture needs at least 40 gallons daily. Your pump’s flow rate (gallons per minute) and the number of peak sun hours in your area will determine how long it needs to run to meet that demand.
Next, consider the "power budget," especially for winter. A de-icer is a significant power draw. You need to account for the pump’s run time plus the de-icer’s potential overnight operation. This total power need (measured in watt-hours) dictates the size of your components.
- Solar Panel (Watts): Must be large enough to fully recharge your battery while also running the pump during the day, even on short winter days. It’s always better to oversize the panel slightly.
- Battery (Amp-Hours): Must be large enough to power your de-icer overnight and run the pump during cloudy periods. Aim for enough capacity to last at least three days with no sun.
- Pump (Voltage/Flow): Must be able to lift water from your source (well depth, pond bank height) and provide the required daily volume in a reasonable amount of time.
Don’t just plan for a perfect sunny day in June. Size your system for the worst-case scenario: a series of overcast, short days in the dead of winter. That’s the true test of a year-round waterer, and getting this calculation right is the key to a system you can truly depend on.
Ultimately, a solar watering system is about buying back your time and providing better care for your animals. By choosing the right components for your specific needs—from a simple all-in-one trough to a robust deep-well pump—you can create a reliable, off-grid solution that eliminates daily chores and ensures your horses always have access to fresh water, no matter the season.
