Maintenance Tips

• Keep panels clean and dust-free; in dusty climates like Pakistan, clean every 2–4 weeks for optimal output.
• Use only soft water and a microfiber cloth or soft brush—avoid abrasives, detergents, or harsh chemicals that can damage the anti-reflective coating.
• Clean early morning or evening when panels are cool to prevent thermal shock and micro-cracks.
• Ensure panels remain unshaded and debris-free (leaves, bird droppings, dust can significantly reduce output).
• Inspect MC4 connectors, junction box, and wiring regularly for looseness, corrosion, or heat damage.
• Check mounting structure periodically to ensure firm alignment and resistance to wind load (up to 2400 Pa wind / 5400 Pa snow rating).
• Monitor system output; a sudden drop may indicate soiling, shading, or a faulty panel/string issue.
• Avoid pressure washers—high pressure can damage seals and allow moisture ingress.
• Ensure proper airflow behind panels to prevent overheating and efficiency loss.
