Manual Fault Diagnosis Labor Costs

2 verified sources

Definition

Earth fault location involves detailed DC string testing (positive/negative-to-ground voltages, Voc calculations), visual inspections, often requiring multiple site visits for scheduling.

Key Findings

  • Financial Impact: AUD 500-1,500 per fault (4-8 hours technician labor at AUD 120-180/hour incl. travel)
  • Frequency: Per fault event; common in operational PV systems
  • Root Cause: Manual processes for fault localization and replacement coordination

Why This Matters

The Pitch: Solar maintenance firms in Australia 🇦🇺 waste 4-8 hours per fault on manual diagnostics. Automation of detection and scheduling cuts technician dispatch costs.

Related Business Risks

Inverter Fault Downtime Losses

AUD 100-500+ per day lost revenue for 5-10kW residential systems (based on typical 20kWh/day output at AUD 0.25-0.50/kWh retail offset)

Underperformance Compensation Claims

AUD 200-1,000+ per incident in lost customer revenue offset and compensation (e.g., 'hundreds of dollars' saved via early fix)

Non-Compliance Penalties & System Disconnection Risk

AUD 10,000–50,000 per installation (estimated statutory penalties); potential loss of entire project revenue if disconnected post-installation.

Lost Government Rebates & Feed-in Tariff Income

AUD 3,000–8,000 per residential installation (typical STC value + 10 years feed-in tariff foregone)

Rectification & Rework Costs Due to Inspection Failures

AUD 2,000–6,000 per failed inspection (electrician callout, parts, re-certification labor)

Grid Approval Delays & Installation Queue Bottlenecks

40–50 hours labor per project (4–8 week calendar delay × AUD 50–100/hour fully loaded cost); lost installation throughput = AUD 5,000–15,000 revenue delay per installer per month
