Maintenance Tips

• Keep panels clean and dust-free; use soft water and a microfiber cloth to maintain peak efficiency.
• Avoid abrasive cleaners, solvents, or pressure washing, which can damage tempered glass and anti-reflective coating.
• Ensure installation remains unshaded throughout the day; even partial shading reduces overall string performance.
• Inspect mounting structure regularly to confirm it is tight, level, and resistant to wind load.
• Check MC4 connectors, junction box, and wiring for loose fittings, corrosion, or heat discoloration.
• Maintain proper airflow behind panels to reduce heat buildup and efficiency loss.
• Monitor system output; sudden drops may indicate soiling, shading, or connection issues rather than panel failure.
• Avoid stepping on or placing heavy loads on panels to prevent micro-cracks in solar cells.
• Clean early morning or late evening to avoid thermal shock from hot panel surfaces.
• Perform an annual inspection of all electrical connections and mounting hardware for long-term reliability.
