Solar Performance Diagnostics & Optimization
Investigation service for solar systems that are underperforming: generation audit, inverter log analysis, string-level checks and monitoring review to find why output dropped and what to do about it.
- Generation audit
- Inverter log analysis
- Monitoring review
- String-level inspection
- Root-cause report
- Prioritised fix plan

Quick Answer
When do you need solar performance diagnostics?
This is an investigation, not routine upkeep. Use it when generation has dropped, your inverter is showing alerts, monitoring data looks wrong, or you cannot tell whether the system is producing what it should — and the cause is unknown.
It is different from a cleaning visit, which only removes surface soiling, and different from an AMC, which is scheduled preventive maintenance. Diagnostics starts from generation data and inverter logs to establish root cause.
