Solar for Agriculture and Farms in Southern Africa
We size your system around how your farm uses power, not just its annual total.
Every farm runs on a different schedule than the grid. Our solar and battery systems need to be sized to your irrigation, cold storage or dairy schedule which can cut farm energy costs from grid tariffs of up to R4.20/kWh down to a fixed R0.45-0.48/kWh. Real system sizing, real payback numbers, and Section 12B guidance for irrigation, cold storage, dairy, poultry and grain operations are imperative and come with all our assessment and design stages of the project.
Bigfisch cannot guarantee Section 12B deductions or payouts; eligibility depends on your tax position, so confirm with your tax adviser.

Reduce Farm Energy Costs with Solar and Battery Storage
When it comes to how much solar can reduce farm energy costs in South Africa, costs typically fall from grid tariffs of R3.23 to R4.20 per kWh to a fixed R0.45 to R0.48 per kWh once a solar and battery system is sized to your irrigation, cold storage or dairy schedule, with payback in three to four years and a 20-year return of 570% to 608% on signed-off agricultural systems.
Farm energy costs, often 15 to 25% of operating costs for medium-scale operations, are one of the few line items a farmer can still act on directly.
Bigfisch Projects designs solar and battery systems sized to your irrigation, cold storage, dairy, poultry or grain schedule, bringing the cost of that energy down to a fixed R0.45-0.48/kWh for the life of the system.
The important thought is that agricultural solar should be sized around how the farm uses electricity; not simply the annual consumption. Irrigation, refrigeration, milking, ventilation and processing can all have very different load profiles.
What We include in Our Recommendations
Unlike larger, corporate-focused solar providers, Bigfisch publishes the real LCOE, payback and ROI figures behind every recommendation, rather than routing every enquiry straight to “talk to us”, and we treat mid-scale farms in the 150,000-500,000 kWh/Year range as a core market rather than an afterthought.
Zero Emission Power. A solar and battery system generates clean energy silently, with no fuel burn and no emissions on-site.
Solar Systems Designed Around Your Farm Energy Use
A grain store, a dairy and a poultry operation do not draw power the same way, so the right system size and battery configuration depends on what is running on your farm.
We assess your actual electricity consumption, operating schedule, tariff, structural and site conditions (roof or ground-mount suitability, dust exposure, security and critical load) before recommending a system. This keeps the technical design connected to the financial case.
Solar for Irrigation and pumping
Irrigation pumps are often a farm’s single biggest electricity draw, and they run hardest during exactly the hours solar generates best. Sizing the system around your pumping schedule, rather than just your total annual usage, is what makes the payback work.
How much solar does irrigation need?
The answer depends on your pumping schedule, energy consumption and available solar resource. Our farm specific assessment is more useful than a standard system size.
Solar and Battery Storage for Cold Storage
Cold stores cannot go offline for the length of a loadshedding stage without risking stock. Battery storage sized to your refrigeration load keeps compressors running through outages, which protects product as well as the power bill.
For cold storage, battery sizing should prioritise the loads that cannot be interrupted rather than simply matching total farm consumption.
Reliable Solar Power for Dairy and Poultry Farms
Ventilation, milking equipment and incubation systems all need consistent, reliable power. A hybrid solar and battery system, with diesel backup where appropriate, keeps these operations running without the fuel cost and maintenance burden of running a generator as the primary backup.

Solar for Farms with Unreliable Grid Connections
Not every farm sits on a strong grid connection. For operations far from a reliable connection, an off-grid or hybrid diesel-solar system can be the more dependable option over the life of the system.
Farm Solar Costs, LCOE, Payback and ROI
We do not deal in vague savings claims. Based on real project modelling supplied for medium-scale agricultural systems:
- Levelised cost of energy: R0.45 to R0.48 per kWh, against a grid tariff of R3.23 to R4.20 per kWh.
- Simple payback: typically 3 years, 7 months to 3 years, 9 months.
- 20-year return on investment: 570% to 608%.
- Section 12B tax allowance: 100% deduction in year one for solar PV systems up to 1 MW and a 50/30/20 write-off over three years for systems above 1 MW (the enhanced 125% allowance expired on 28 February 2025), per SARS guidance.

Every farm has its own tariff, load profile and cash-flow position. If you’d rather spread the cost than pay upfront, our Solar as a Service Financing information covers PPA and lease structures for agricultural sites.
Trusted Farm Solar Delivery Across Southern Africa
Our agricultural portfolio includes a 4.5MWp solar and diesel hybrid at Nottingham Estate, a citrus farm on the banks of the Limpopo River that needed energy security it could rely on for generations, not just one season.

From Assessment to Grid Compliance
From initial assessment and system design through procurement, installation and grid compliance, we manage the project around your farm’s operational requirements.
Where relevant, Small Scale Embedded Generation registration and grid compliance are handled as part of the end-to-end process, so there is less for the farm owner to manage.
Frequently Asked Questions
How is my farm’s tariff used in the savings calculation?
We model your system against your actual municipal or Eskom agricultural tariff, such as the Emfuleni Agriculture Conventional tariff, rather than a generic national average, so the numbers reflect what you pay.
How long does installation take once we sign?
Most medium-scale agricultural systems move through design, procurement and construction within roughly 8 to 14 weeks after the feasibility study, with SSEG approval adding a further 4 to 8 weeks depending on your municipality.
Do I still qualify for the Section 12B tax allowance on a farm asset?
Typically, yes, for qualifying renewable energy assets you own outright, the allowance permits a 100% deduction in year one for solar PV systems up to 1 MW and a 50/30/20 write-off over three years for systems above 1 MW (the enhanced 125% allowance expired on 28 February 2025). Eligibility depends on your specific farm structure, so confirm with your tax advisor before relying on this for planning.
Does Bigfisch Projects handle SSEG registration for farms?
Yes, we do. Small Scale Embedded Generation registration and grid compliance are handled as part of our end-to-end process, so it is one less thing for you to manage.
What happens to my systems during load-shedding?
Battery storage keeps your critical loads (irrigation controllers, cold storage compressors, milking equipment) running through an outage. Sizing that battery correctly for your specific loads, not just your total usage, is part of the technical review.
