Summary: Solar water pumps are vital for off-grid agriculture and rural water supply. This guide explains how to troubleshoot and repair common solar pump issues, with real-world examples and maintenance tips to keep your system running efficiently.

Understanding Solar Water Pump Failures

Solar-powered pumps serve 2.8 million farms globally, according to 2023 renewable energy reports. When your pump stops working, it could mean crop losses or disrupted water access. Let''s break down the repair process:

Diagnostic Tools You''ll Need

• Multimeter ($15-$50)
• Insulation tester
• Solar irradiance meter
• Pipe pressure gauge

"80% of solar pump failures stem from electrical connections – not the pump itself," says EK SOLAR''s lead engineer.

Step-by-Step Repair Process

1. Check Solar Power Supply

Start with these quick tests:

• Measure panel output: Should be 18-40V DC in daylight
• Inspect cables for rodent damage (common in rural areas)
• Test charge controller LEDs

Component	Normal Voltage	Fault Threshold
Solar Panel	24-38V	<18V
Battery (if used)	12.6V	<11.5V

2. Pump Motor Troubleshooting

Hear strange noises? Try this:

• Check for sand in impellers (common in borehole pumps)
• Test winding resistance: 2-10Ω typically
• Look for water in motor housing
