⚠ Why 72.3%? Inverter 2 on SYS-004 developed MPPT tracking fault on Apr 8. Output dropped 40% on that string. Combined with 3 overcast days (Apr 8-10), Week 2 saw 5.8% below-expected generation fleet-wide.

Recommendations
🔧
Investigate Inverter 2 Fault (SYS-004)
MPPT tracking deviation detected since Apr 8 — 40% output loss on String B. Dispatch technician for on-site diagnosis to identify root cause (contactor, MPPT board, or DC wiring). Estimated lost revenue: ~$67/day.
💰 Recovering ~$67/day📈 Fleet PR from 94.2% → 97%+
🧹
Schedule Panel Cleaning — All Systems
Gradual output decline trend detected across fleet, consistent with panel soiling. On-site visual inspection and cleaning recommended bi-weekly during dry season.
📈 +2.5% Performance Recovery💰 ~$90/month
