Farm Operations Are Held Hostage by Eskom — and Diesel
Agricultural operations face a uniquely acute energy challenge. Irrigation pumps, packhouses, cold storage, and general farm operations all run on electricity — and most farm supply is either expensive municipal power or costly diesel generation. Load shedding during critical irrigation windows directly impacts crop yields.
Specific pain points:
- Irrigation pumps running on expensive Eskom or diesel during peak daylight hours
- Load shedding disrupting irrigation schedules at critical crop growth stages
- Generator fuel costs escalating with increased outage frequency
- Large land area ideal for ground-mounted solar but requiring proper design
Solar + Genset Integration — Farm Power That Works With Nature
Gentricity designed a system that aligned solar generation with Plantation Farms' operational rhythm:
System specifications:
- 137 kWp solar array — roof-mounted and/or ground-mounted to suit available surfaces
- Intelligent transfer switch integrating existing generator with solar supply
- Solar-first priority: pumps and operations run on solar during daylight
- Generator activates automatically only when solar generation is insufficient
- Real-time monitoring with remote visibility on generation and consumption
Why this configuration:
- Irrigation pumping is a daylight activity — solar covers it almost entirely
- Generator integration eliminates reliance on Eskom without expensive battery banks
- Fuel savings from reduced generator run hours improve operating margins immediately
- System is expandable as the farming operation grows
Results (Estimated based on system specifications and industry benchmarks)
| Metric | Estimated Value |
|---|---|
| Irrigation electricity cost reduction | 60–80% |
| Generator run hours reduction | 60–75% |
| Estimated annual savings | R400,000 – R600,000 |
| Payback period | 3–5 years |
| Carbon offset | ~170 tonnes CO2/year |
Note: Figures are estimates based on system size and SA commercial solar benchmarks. Actual results may vary.
What This Project Demonstrates
For farming operations and agricultural businesses:
- 137 kWp covers the majority of daytime farm operations without battery investment
- Generator integration provides seamless backup during cloudy periods and after hours
- Fuel savings alone can significantly improve the ROI of the combined system
- Agricultural solar systems qualify for Section 12B — meaningful tax benefit for profitable farming operations
