Two different moments
Preventive maintenance is scheduled while the system is still operating. Corrective maintenance starts after a fault, damaged component or interruption requires diagnosis and repair.
Why prevention matters
A solar system may continue producing while dirt accumulates, WiFi monitoring disconnects or components begin to show wear. Scheduled attention helps reduce surprises.
What a preventive visit may include
Seré Solar can provide panel cleaning, inverter cleaning, DC and AC connection inspection, WiFi configuration and photographic reporting.
When it becomes corrective
Inverter alarms, loss of production, visible damage, burned connections or failed components require a diagnostic and repair process.
The practical goal
Maintenance cannot eliminate every possible failure, but it can create enough visibility and service history to identify problems earlier and resolve them in an orderly way.
