Solutions

Diagnostic Steps

1. Check for Shading: Ensure panels are not shaded by trees or buildings
2. Inspect Panel Condition: Look for damage, dirt, or debris
3. Monitor Inverter: Check if the inverter is functioning properly
4. Review Weather Conditions: Cloudy days reduce production
5. Check System Monitoring: Use monitoring software to track performance

Common Solutions

• Clean Panels: Dirty panels can reduce efficiency by 10-25%
• Trim Trees: Remove branches that shade panels
• Check Connections: Ensure all electrical connections are secure
• Reset Inverter: Power cycle the inverter if needed
• Professional Inspection: May need panel replacement or repair

Prevention Tips

• Schedule regular panel cleaning
• Monitor system performance monthly
• Keep trees trimmed around panels
