How MK3 works

A solar repair process built to reduce uncertainty.

When the system is down or the original installer is gone, homeowners need to know what happens next. MK3’s process starts with the symptom, moves through onsite diagnosis, then explains repair options based on the equipment and findings.

The service path

Know what happens after you call.

Share the issue

Provide the address or ZIP, system status, installer if known, equipment brand, error message and useful screenshots.

Diagnostic visit

MK3 inspects the system and traces the likely failure point before recommending the next step.

Repair options

The findings determine whether the next step is repair, compatible component replacement, monitoring work, manufacturer support, or another path.

Restore & verify

Complete approved work and verify practical operation or monitoring where the equipment and platform allow it.
