Can solar power run a borehole pump?

Yes — solar-powered submersible pumps are widely used across South Africa for borehole applications. Modern solar pump systems can run pumps from depths of over 200m. The system can include battery storage for night-time operation or work as a direct-drive daytime system.

How many solar panels do I need for a water pump?

The number of panels depends on pump size, depth, and daily water demand. A typical borehole pump system requires 4–12 panels (1.5–5 kW). iWater sizes every system specifically to your site's requirements and solar conditions.

Do solar pumping systems work on cloudy days?

Direct-drive systems reduce output on cloudy days but still function. Systems with battery storage continue at full capacity regardless of weather. Hybrid solar-grid configurations provide uninterrupted supply by switching to mains power when solar generation is insufficient.

What is the lifespan of a solar water pumping system?

Solar panels typically last 25–30 years with minimal degradation. Inverters and charge controllers last 10–15 years, and batteries 5–10 years depending on type (lithium vs lead-acid). Pumps are serviced on standard maintenance intervals.

How much can I save with solar-powered water systems?

Solar systems typically reduce energy costs by 60–90% compared to grid-powered pumping. Most systems pay for themselves within 3–5 years through electricity savings, after which water pumping is essentially free.

Can I add solar to my existing water system?

Yes — we regularly retrofit solar power to existing borehole pumps, booster systems, and treatment plants. Our engineers assess your current setup and design a solar solution that integrates seamlessly with your existing infrastructure.
