Solar Grazing System

Solar power for more than electricity generation.
A Solar Grazing System combines solar PV, battery storage and practical farm equipment to support everyday grazing operations - including water pumping, electric fencing, livestock monitoring, farm lighting and small electric equipment.
Designed as a customized farm energy solution, the system can be adapted to the size of the farm, livestock numbers, water requirements, grazing pattern and available solar resources.
As a concept example, we developed a system for a 50-hectare Scottish sheep farm with approximately 100 sheep, with an estimated daily electrical demand of around 5–6 kWh/day.
The objective is simple:
Use solar energy to make everyday farm management easier.

 

Parameter	Concept Example
Farm size	Approximately 50 hectares
Livestock	Approximately 100 sheep
Estimated daily electrical demand	5–6 kWh/day
Suggested PV capacity	Approx. 5–6 kWp
Suggested battery capacity	Approx. 10–15 kWh usable
Main application	Grazing and remote farm operations
System type	Off-grid / hybrid / grid-connected
Design approach	Customized according to farm requirements

Note: These figures are preliminary concept values rather than fixed product specifications. Final system sizing depends on local solar conditions, water demand, pump head, equipment selection, operating hours, seasonal requirements and required battery autonomy.

 

Traditional solar installations on farms are usually designed around one objective: generate electricity.

A Solar Grazing System takes a different approach.

Instead of asking only:

How much electricity can the solar panels generate?

we ask:

What farm operations can this electricity support?

The system connects solar generation with practical grazing applications such as:

For a typical grazing scenario, imagine a 50-hectare farm with approximately 100 sheep.

The farm uses rotational grazing and has several grazing areas distributed across the property.

The main energy-related challenges may include:

• Supplying water to remote grazing areas
• Operating electric fences
• Monitoring livestock and pasture conditions
• Maintaining remote infrastructure
• Providing power where grid electricity is unavailable
• Charging small electric equipment
• Reducing unnecessary manual work

Rather than installing a large solar system for general electricity consumption, we can build a smaller, purpose-designed energy system around the farm's actual operating needs.

 

A conceptual daily load profile could look like this:

Farm Application	Estimated Daily Energy
Water pumping	~1.5 kWh
Electric fencing	~0.15 kWh
Sensors & livestock monitoring	~0.30 kWh
Communications	~0.20 kWh
CCTV / remote monitoring	~0.50 kWh
LED lighting	~0.25 kWh
Small electric tools	~0.50 kWh
Utility vehicle charging	~2.00 kWh
Total	~5.4 kWh/day

These figures are intended for system concept development, not as guaranteed consumption values.

Actual electricity demand can vary significantly depending on the pump, water requirements, livestock monitoring equipment, vehicle usage and seasonal operating conditions.

 

Based on this concept, a preliminary system could be designed around:

5–6 kWp Solar PV

The PV array provides the main source of renewable electricity.

During periods of good solar production, flexible loads such as water pumping and battery charging can be operated during the daytime.

10–15 kWh Usable Battery Storage

Battery storage supports loads that need to continue operating after sunset or during periods of low solar generation.

Typical battery-supported loads include:

• Electric fencing
• Sensors
• Livestock monitoring
• Communications
• CCTV
• Lighting

The final battery capacity would be determined by the required autonomy and the farm's seasonal operating profile.

 

Water management is one of the strongest applications for solar energy on a grazing farm.

Water may need to be moved from:

• Ponds
• Boreholes
• Springs
• Storage tanks
• Other remote water sources

to livestock troughs located in different grazing areas.

A solar-powered pumping system can be configured as:

Solar PV → Pump Controller → Water Pump → Storage Tank → Livestock Trough

A water storage tank provides an additional advantage.

The pump does not necessarily need to operate at the exact time the animals consume water.

Solar energy can be used during the day to fill the tank, while stored water can be used later.

This allows the farm to use water storage as a form of operational energy storage, reducing the need to oversize the battery.

 

Rotational grazing often requires flexible control of grazing areas.

Electric fencing can divide a larger pasture into smaller grazing zones and help control when and where livestock graze.

The electrical consumption of a fence energizer is relatively small, making it highly suitable for a solar-powered system.

A typical configuration is:

Solar PV → Battery → Fence Energizer → Electric Fence

The same solar energy system can therefore support both:

energy generation

and

grazing management.

 

A 50-hectare farm may have infrastructure distributed across a large area.

Instead of manually checking everything every day, a Solar Grazing System can provide power for remote monitoring equipment.

Possible applications include:

Water Monitoring

Check tank levels and pump operation remotely.

Fence Monitoring

Receive an alert if the fence system stops operating.

CCTV

Monitor remote gates, equipment or livestock areas.

Weather Monitoring

Collect local information about temperature, rainfall and other conditions.

This turns the solar system into more than an energy source.

It becomes part of the farm's remote management infrastructure.

 

Not every farm machine needs to be electrified.

Large tractors and heavy agricultural equipment are not necessarily the best targets for a small solar energy system.

However, many smaller operations can be electrified more easily.

Potential applications include:

• Electric brush cutters
• Small electric mowers
• Hedge trimmers
• Small pumps
• Battery-powered maintenance tools
• Electric utility vehicles
• Electric quad bikes

The Solar Grazing Hub can provide a convenient charging point for these devices.

This allows the farm to gradually introduce electric equipment without attempting to replace all conventional machinery at once.

 

The core of the system is a compact Farm Energy Hub.

The system can be configured as:

• Off-grid
• Grid-connected
• Hybrid with backup power

depending on the farm's infrastructure

One important principle in system design is that not every electrical load needs to be powered by the battery.

Where possible, flexible loads should operate when solar energy is available.

Every farm is different.

A 50-hectare sheep farm is not necessarily going to have the same energy requirements as a 100-hectare cattle farm.

The system should therefore be designed around the farm rather than forcing the farm to fit a standard package.

We can assess:

The result can be a modular solar energy system matched to the actual farm operation.

 

Our experience is not limited to standard solar mounting systems.

For agricultural projects, the structure is only one part of the solution.

We work with manufacturing and supply partners to develop solutions according to the customer's requirements.

For non-standard projects, we can also help evaluate production feasibility, equipment sourcing, technical communication, quality control and delivery coordination.

 

A Solar Grazing System does not have to be installed all at once.

A farm could start with:

A customized Solar Grazing System can be considered for:

• Sheep farms
• Cattle farms
• Mixed livestock farms
• Remote grazing areas
• Rural businesses
• Off-grid agricultural sites
• Solar farms with livestock grazing
• Agri-PV projects
• Farms looking to reduce diesel use
• Farms requiring remote water pumping

It can also be useful for solar installers and agricultural contractors who need a customized energy solution for a farm customer rather than a standard residential PV package.

 

The future of agricultural solar may not simply be about putting more PV panels on farmland.

It can also be about connecting renewable energy with the way farms actually operate.

• Water.
• Grazing.
• Livestock.
• Monitoring.
• Maintenance.
• Mobility.

These are all parts of a modern farm energy system.

Our approach is to help customers connect these requirements into a practical, customized solution.

We don't just supply solar structures. We help turn solar energy into practical farm operations.
