A maize farmer in Kitui used a 5HP diesel pump to irrigate 2 acres—running it 4 hours daily during dry season. His monthly fuel bill? KES 18,500. Add KES 3,200 for maintenance and spare parts, and the total hit KES 21,700/month. Over 5 years, that’s over KES 1.3 million—before accounting for rising fuel prices or downtime.
In 2025, he switched to a 3kW solar water pumping system from SkyGen:
12 x 275W solar panels
Submersible DC pump (5HP equivalent)
Controller with dry-run protection
Upfront cost: KES 420,000
Payback period: 22 months
Annual running cost: ~KES 8,000 (cleaning + occasional part replacement)
After 18 months:
✓ Zero fuel costs
✓ No engine noise or emissions
✓ Reliable operation—even during extended outages
✓ 30% more consistent water supply (no refueling delays)
Key insight: While diesel feels “cheap” upfront, solar wins on total cost of ownership—and resilience. With Kenya’s average 6–7 peak sun hours, solar pumps deliver 90%+ uptime year-round.
For farms using >2 hours/day of pumping, solar pays for itself in under 2 years. We’ll help you size the right system—no guesswork.
