Common Issues With Your Solar
Recognise any of these symptoms? Your solar system is telling you something. We listen, diagnose, and treat.
Flatlined Energy Generation
Your bills haven't changed but your generation readings have dropped sharply. Hidden panel degradation, shading faults, or wiring failures could be draining your output silently.
Output LossCryptic Error Codes
Error strings and fault codes on your inverter display can indicate anything from a grid voltage issue to a failed string. We translate and treat the underlying cause.
System ErrorOffline or Unresponsive Monitoring
If your monitoring app has gone dark or shows stale data, your system may have disconnected or failed entirely. Silent failures are the most costly of all.
Monitoring LossBattery Not Charging or Discharging
A battery storage system that won't charge or won't release stored energy represents a significant loss of the investment you made in energy independence.
Battery IssueHot Spots and Panel Damage
Thermal hot spots caused by cell defects or soiling can silently reduce panel efficiency for years. Our thermal imaging and IV curve testing locate them precisely.

Patients Restored to Full Health
"
Our inverter had been showing a fault code for three months and two other companies told us we needed a full replacement. Doctor Solar diagnosed a failed component, repaired it on the same visit, and we were generating again by lunchtime. Outstanding.
"
We manage a portfolio of commercial properties, several with solar. Doctor Solar now handles our annual health servicing across all sites. The certificates are thorough and the engineers are professional and efficient.
"
Noticed my generation had dropped by almost a third. Doctor Solar ran thermal imaging and found two failed cells in one panel. Replaced it, ran the full test suite, and gave me a written health report. Exactly what you want.
