Microgrid and Shared Solar for Gold-Mine Pumps in Mauritania
Introduction
One pump is simple; a whole mine with several duty points is a small power system, and a shared solar microgrid beats many isolated arrays. This article covers microgrid and shared solar for gold-mine pumps, using Mauritania’s Tasiast-corridor goldfields as the worked example, written by the solar-pumping specialists at KINBO. A shared DC or AC bus lets several pumps draw from one array, the system view alongside our off-grid vs grid-tied guide.

Why a Microgrid Pays Off
- One array, many pumps—a shared bus feeds several duty points from a single, better-utilised array.
- Cheaper storage—pooled buffering beats per-pump batteries, per our TCO guide.
- Simpler control—one controller family and one monitoring pane cover the site.
- Scales with the mine—add a pump or a row without redesigning from scratch, per the sizing plan.
Mauritania Goldfield Conditions
Mauritania’s desert goldfields around Tasiast are flat, sunny and spread out, ideal for a central array feeding scattered duty points. Our dust-and-heat guide and off-grid guide frame the duties; here the prize is one coherent power system instead of five lonely arrays.
Designing a Shared Solar Microgrid, Step-by-Step
- Map the loads—from the sizing, total the duty of every pump and its timing.
- Pick the bus—DC bus for close pumps, AC for distant ones, via the controller set.
- Size one array—a single structure sized to combined peak, with headroom for growth.
- Pool the storage—one shared bank sized to the combined evening duty.
- Monitor centrally—monitoring tracks the bus, not just each pump.
- Plan expansion—leave bus and combiner capacity for the next duty point.
Shared Microgrid vs Isolated Pumps
| Aspect | Shared microgrid | Isolated pumps |
|---|---|---|
| Array use | High, shared | Low, duplicated |
| Storage | One pooled bank | Per pump |
| Oversight | Single pane | Scattered |
For the ownership maths, our TCO guide compares the two on capex and O&M.
Frequently Asked Questions
When does a microgrid beat isolated pumps?
Once you have two or more duty points with overlapping sun hours, a shared bus saves array and battery, per our TCO guide.
DC or AC bus?
DC for nearby pumps, AC for distant ones—the controller choice follows the site layout.
Is it harder to monitor?
Easier—monitoring watches one bus, so faults surface faster than across five sites.
How do I start a Mauritania microgrid?
Share your Tasiast-corridor duty points and we design one shared solar bus that feeds every pump from a single array.
