Fault isolation
Use alarms, operating data, inspection, and field testing to narrow the source of the issue.
Commercial solar repair and corrective maintenance

01 Corrective service
A fault is only the starting point
Restore equipment.
Confirm production.
Commercial solar problems rarely resolve themselves. Inverter faults, failed communications, damaged wiring, degraded components, open circuits, and recurring alarms can leave the asset producing below expectation even when the system appears generally online.
TerraSun approaches repair as a complete operating task: establish the symptoms, diagnose the cause, complete the corrective work, test the equipment, and close the loop with clear documentation.
Inverter repair
Troubleshooting and corrective work for central inverter faults and performance problems.
Electrical repair
Corrective work for wiring, connections, enclosures, and other identified electrical defects.
Component replacement
Replacement of failed or damaged components when supported by verified findings and the repair plan.
Communications recovery
Investigation of monitoring and communication failures that limit visibility or issue response.
Operating verification
Post-repair testing and documentation to confirm the equipment’s return to dependable service.
02 The corrective workflow
Clear ownership of the next action
Diagnose.
Repair. Verify.
Corrective maintenance succeeds when every handoff is visible. TerraSun keeps the issue, supporting evidence, parts needs, field work, test result, and open recommendations connected.
- Review the reported symptom and production impact
- Confirm site conditions and safe access
- Perform targeted diagnostics and testing
- Complete the approved corrective action
- Verify post-repair operating behavior
- Record findings, work performed, and follow-up

More verified recovery.
Clear diagnosis
Separate symptoms from the underlying equipment or system issue.
Focused repair

04 Common questions
Solar repair
service answers.
Can TerraSun respond to a single repair need?
Yes. A defined fault, alarm, offline inverter, or production issue can be evaluated as a corrective-service request without first establishing a full O&M program.
What information should accompany a repair request?
Helpful information includes site location, system size, equipment type, alarms or fault codes, current operating condition, recent production history, photographs, and prior service attempts.
What happens after the repair?
The corrective process includes post-work checks and documentation so the owner can understand what was found, what was completed, how operation was verified, and what follow-up remains.
