This controller is ideal for simple, single-panel systems powering light-duty DC pumps. It is not suitable for systems that you plan to expand beyond 120 watts of total solar input.

Deep Cycle Battery – Mighty Max 12V 35AH

Pumping water cannot rely solely on active sunlight, as livestock drink during overcast days and early mornings. A deep cycle battery stores the energy generated during peak sun hours so your pump can run whenever needed.

The Mighty Max 12V 35AH uses Absorbed Glass Mat (AGM) technology, making it completely spill-proof and maintenance-free. Its rugged outer casing resists the vibrations and temperature swings typical of outdoor farm environments.

Keep the battery inside a protective enclosure and avoid discharging it past 50% capacity to ensure it lasts for years.

• 35 Amp-Hour capacity
• Maintenance-free AGM design
• High discharge rate recovery

This battery is perfect for weekend farmers running small-scale, on-demand pumping cycles. It is not beefy enough for continuous-duty irrigation systems or large herds requiring constant water flow.

Submersible Pump – ECO-WORTHY 12V DC Pump

The submersible pump does the heavy lifting, pushing water from your source up into the stock tank. Choosing a pump that matches your voltage and lift requirements ensures efficient water delivery without wasting battery power.

The ECO-WORTHY 12V DC Pump offers excellent lift capability and a corrosion-resistant housing that holds up in deep water. Its quick-disconnect design allows for easy cleaning of the internal stainless steel screen.

Always use a pre-filter if your water source contains silt or sand, as debris can quickly wear out the internal diaphragm.

• 3.2 Gallons Per Minute flow rate
• Maximum lift of 230 feet
• 12-volt DC operation

This pump is excellent for shallow wells, spring boxes, and clean ponds. It is not the right choice for deep wells where the water table sits lower than 150 feet.

Float Switch – Sump Alarm Tethered Switch

An automated float switch prevents your stock tank from overflowing and saves your battery from running dry. It acts as an automatic switch, turning the pump on when the water level drops and off when the tank is full.

The Sump Alarm Tethered Switch features a heavy-duty microswitch encased in a durable, leak-proof housing. Its adjustable tether allows you to easily customize the water level depth before the pump triggers.

Secure the switch cable firmly to the side of the tank or a stake so livestock cannot pull or chew on the wiring.

• Mechanically-activated microswitch
• 10-foot highly flexible cord
• Corrosion-resistant casing

This switch is essential for automated, worry-free pasture watering systems. It is not necessary if you prefer to manually control your pump during daily farm visits.

Stock Tank – Behlen Country 100-Gal Poly

The stock tank is the final destination for your water, providing your livestock with safe and easy access to clean drinking water. It must withstand both harsh weather conditions and the physical abuse of thirsty animals.

The Behlen Country 100-Gal Poly tank is molded from high-density polyethylene that resists cracking from winter freezes and summer UV rays. The heavy-duty rim provides structural rigidity and gives animals a safe edge to drink from.

Place the tank on a level, compacted gravel pad to prevent shifting and uneven stress on the plastic walls when full.

• 100-gallon capacity
• UV-stabilized poly construction
• Built-in drain plug

This tank size is ideal for small herds of sheep, goats, or a few head of cattle. It is not large enough for large-scale cattle operations where multiple animals drink simultaneously.

Battery Enclosure – Minn Kota Power Center

Sensitive electrical components like batteries and charge controllers must be protected from rain, dust, and rodents. A dedicated battery enclosure keeps your wiring organized and dry, preventing accidental short circuits.

The Minn Kota Power Center is a rugged, portable battery box featuring built-in external terminals and an integrated battery meter. It also includes manual reset circuit breakers to protect your pump and controller from power surges.

Seal any custom wire entry holes with silicone sealant to keep nesting mice and moisture out of the box.

• Built-in push-button battery meter
• Dual 12-volt accessory plugs
• Manual reset circuit breakers

This enclosure is perfect for keeping small-scale solar electronics organized and weather-protected. It will not fit oversized industrial batteries or complex multi-battery banks.

Irrigation Tubing – Rain Bird 1/2-Inch Hose

Irrigation tubing connects your pump to the stock tank, carrying the water safely across your pasture. It must be flexible enough to navigate rough terrain but strong enough to handle constant water pressure.

The Rain Bird 1/2-Inch Hose is made from high-quality, UV-resistant polyethylene that resists kinking and cracking. Its dark color prevents algae growth inside the line, keeping your water flowing freely.

Lay the tubing out in the warm sun before installation to make it more pliable and easier to trench or secure.

• 0.5-inch inner diameter
• UV-resistant black polyethylene
• 70 PSI pressure rating

This tubing is perfect for low-pressure solar pumping lines over moderate distances. It is not suitable for high-pressure municipal water hookups or heavy-duty burial lines under vehicle crossings.

Sizing Your Solar Array for Daily Water Needs

Sizing your system correctly starts with calculating the daily water needs of your herd. A single beef cow can drink up to 15 gallons per day in hot weather, while sheep generally require around 2 gallons. Multiply these numbers by your herd size to find your daily target.

Next, calculate how long your pump must run to meet this target. A pump pushing 3.2 gallons per minute will deliver roughly 100 gallons in 30 minutes, drawing very little power from your battery. Your 100W solar panel can easily replenish this draw within an hour of good sunlight.

Always build a safety margin into your calculations to account for cloudy days. Oversizing your battery and solar panel capacity by 20% ensures your system keeps running even during a string of overcast weather.

Winterizing Your Remote Solar Water Station

Freezing water is the enemy of any plumbing system, as expanding ice can split hoses and crack pump housings. Before the first hard freeze, drain all above-ground lines completely and store your pump in a dry, frost-free location if not in use.

Cold weather also drastically reduces battery performance and capacity. Keep your battery fully charged, or consider burying the enclosure in an insulated ground pit to protect it from sub-zero temperatures.

If you must run the system during winter, implement a drain-back design. This setup allows water in the vertical delivery pipe to drain back down below the frost line whenever the pump shuts off, preventing ice blockages.

Keeping Your Livestock Hydrated Year-Round

Providing clean, reliable water in remote pastures is key to successful rotational grazing and pasture management. It keeps your animals out of sensitive natural streams, reducing erosion and protecting water quality downstream.

Regular maintenance is the secret to keeping your solar watering station running smoothly year after year. Clean the stock tank weekly to prevent algae buildup, and occasionally wipe dust off the solar panel to maintain peak charging efficiency.

Investing in high-quality, matched components saves you countless hours of manual labor and worry. A reliable solar waterer ensures your livestock stay healthy and hydrated, leaving you more time to focus on other farm tasks.

Building a remote solar watering station is a practical, rewarding project that transforms how you manage your livestock. By assembling these eight essential pieces of equipment, you create a self-sustaining system that delivers clean water where it is needed most. Your animals will stay hydrated, and you will finally be free from the daily chore of hauling heavy water buckets.
