Maintain Solar Panels to Prevent Output Loss

Cost Savings

Checklist Tasks

• Inspect panel surfaces for droppings or sap to prevent sunlight blockage and loss.
• Check for cracked or clouded glass to spot weather or impact damage early.
• Tighten mounting hardware and brackets to avoid wind loosening or roof leaks.
• Clear debris from panel edges and under mounts to prevent water pooling and corrosion.
• Verify inverter status lights and codes to catch silent faults before energy loss.
• Test ground fault protection devices to ensure electrical safety and compliance.
• Trim overhanging branches to reduce shading and debris that lower panel output.
• Examine wiring insulation for UV or rodent damage to prevent shorts and fire risk.
• Review energy logs for sudden drops that may reveal hidden panel or inverter faults.
• Flush panels with deionized water to prevent mineral deposits etching the glass.
• Check roof penetrations for cracked sealant or flashing to avoid leaks and damage.
• Document serial numbers and warranty status to streamline future warranty claims.
