Solar Power for Centre Pivot Irrigation in Zimbabwe

A Practical Guide to Reducing Irrigation Costs with Mobile Solar Power

Centre pivot irrigation has transformed farming across Zimbabwe, allowing farmers to irrigate large areas efficiently and improve crop yields. However, keeping a pivot running comes at a cost.

For many farms, the biggest challenges are:

• Rising diesel prices

• Unreliable grid electricity

• High generator maintenance costs

• Fuel theft

• Power interruptions during critical irrigation periods

These challenges can directly affect crop production, operating costs and profitability.

Mobile solar power offers a practical alternative for many irrigation applications, providing reliable electricity wherever it is needed without relying solely on diesel generators or the national grid.

Why Centre Pivots Need Reliable Power

A centre pivot is only productive when it is running.

Unexpected power interruptions can lead to:

• Reduced crop yields

• Uneven irrigation

• Plant stress

• Lost production time

• Increased labour costs

Reliable power is therefore just as important as the irrigation system itself.

The Hidden Cost of Diesel Irrigation

Many farmers focus on the purchase price of a generator but overlook its long-term operating costs.

Running a diesel generator also means paying for:

• Fuel

• Engine servicing

• Oil changes

• Filters

• Repairs

• Transporting fuel to the field

• Generator downtime

• Fuel theft

These costs continue year after year.

Solar power significantly reduces these ongoing operating expenses while providing a cleaner and quieter source of energy.

Can Solar Power Run a Centre Pivot?

Yes, but it depends on the system.

Every centre pivot is different.

The correct solution depends on factors such as:

• Pump size

• Motor size

• Starting current

• Water pressure requirements

• Number of hours operated each day

• Distance from existing power

• Battery backup requirements

This is why every Volt Wagon is designed around the customer's application rather than using a one-size-fits-all approach.

Why Mobile Solar Makes Sense

Unlike permanent solar installations, Volt Wagon provides portable power.

This means one system can potentially be moved between:

• Multiple pivots

• Boreholes

• Workshops

• Farm offices

• Electric fencing

• Temporary pumping stations

Instead of installing several fixed systems around the farm, the same mobile unit can be deployed wherever power is needed most.

This flexibility helps maximise the return on your investment.

When Does a Volt Wagon Make the Most Sense?

A mobile solar power solution is particularly valuable when:

• The pivot is located far from grid electricity.

• Running new power lines is expensive.

• Diesel costs are becoming difficult to manage.

• Temporary irrigation is required.

• Additional seasonal pumping capacity is needed.

• Reliable backup power is required during outages.

For many farms, the cost of extending electrical infrastructure can exceed the cost of implementing a mobile power solution.

What Information Do We Need?

You don't need to calculate everything yourself.

Simply send us:

• Pump make and model

• Motor size (kW or HP)

• Photos of the motor rating plate

• Centre pivot model

• Generator size (if currently used)

• Number of irrigation hours per day

• Photos of your installation

We'll calculate the power requirements and recommend the most suitable Volt Wagon.

Designed Around Your Farm

Every farm is different.

Some require power for:

• A single borehole.

• One centre pivot.

• Multiple pivots.

• Irrigation plus a workshop.

• Irrigation plus staff accommodation.

• Seasonal irrigation only.

Rather than selling a standard package, Volt Wagon is designed around your operation, allowing you to invest in a solution that matches your current and future requirements.

Frequently Asked Questions

Can a Volt Wagon power a centre pivot?

Yes, provided the system is correctly designed around the pump, motor and starting load requirements.

Can the same Volt Wagon power other equipment?

Yes. Many customers also use their Volt Wagon for workshops, offices, lighting, boreholes and other farm equipment.

What happens on cloudy days?

Battery storage helps maintain power, while every system is designed according to the customer's operating requirements and local conditions.

Is mobile solar better than a generator?

For many applications, mobile solar offers significantly lower running costs, less maintenance, quieter operation and zero fuel consumption.

Can Volt Wagon be moved between pivots?

Yes. That's one of its biggest advantages. It can be towed to different locations around the farm as required.

Conclusion

Reliable irrigation depends on reliable power.

Whether you're looking to reduce diesel costs, improve energy security or bring electricity to remote parts of your farm, a mobile solar solution can provide a practical alternative.

Volt Wagon is designed around your operation, helping you power your centre pivot efficiently while reducing long-term operating costs.

If you're unsure what size system you need, simply send us your pump specifications or photos of your equipment. We'll do the calculations and recommend the right solution.
