Understanding the Problem: Common Causes and Fixes

If your solar water pump is making noise but not delivering water, you're likely dealing with one of these issues:

• Airlock in the suction line (accounts for 40% of solar pump failures)
• Low solar irradiance below 400 W/m²
• Faulty pressure switch or controller
• Impeller blockage from sediment

Case Study: Agricultural Application in Arid Regions

A 2023 field test in Kenya showed 78% of solar pump failures were caused by improper installation. When technicians adjusted the suction lift below 6 meters and installed sediment filters:

Metric	Before Fix	After Fix
Daily Output	0 L	3,500 L
System Noise	75 dB	52 dB
