Solar Panel Maintenance & Repair

Every solar panel system needs periodic maintenance to perform at its best. Inverters can develop faults, DC isolators degrade over time, and wiring connections can loosen — especially on systems over three to four years old. If your original installer has closed down, finding a qualified PV electrician to take over your system's care is essential.

A typical annual maintenance visit includes checking generation data against expected output, inspecting all electrical connections, testing the DC isolator, verifying earthing and bonding, and checking the condition of panels and mounting hardware. For systems with battery storage, the battery health and charge cycles are also reviewed.
