What maintenance do ground-mounted solar arrays require?

Cleaning and Inspections

Ground-mounted solar arrays require cleaning at least twice a year, and more frequently in areas with high dust, pollen, or bird activity. Use a soft-bristled brush or a water hose with a wide fan spray to clean the panels, avoiding any harsh chemicals or abrasive materials that can damage the surface. Regular inspections should be performed every quarter, checking for signs of wear, damage, or malfunction on the mounts, wiring, and inverters.

Mount Maintenance

The ground mounts themselves require occasional lubrication to keep the moving parts running smoothly. Apply silicone-based lubricant to the pivot points and hinges according to the manufacturer’s schedule or after extreme weather conditions. Also, check the mounting system’s stability and levelness every year, making adjustments as necessary to prevent damage or shifting.

Inverter and Electrical Checks

Inverters should be checked every 6 months to ensure they’re functioning correctly and not producing excessive heat. Monitor the inverter’s output and temperature readings, and consult the user manual for specific guidelines on maintenance and troubleshooting. Additionally, inspect the electrical connections and wiring for signs of wear, damage, or corrosion, replacing any faulty components promptly to maintain system reliability.
