Recommendations
🔧
Urgent: Investigate Inverter Fault (SYS-004)
MPPT tracking deviation detected since Apr 8 — output 40% below expected on String B. Dispatch technician for on-site diagnosis. Possible causes: contactor failure, MPPT board fault, or DC wiring issue.
💰 Lost output: ~$67/day📈 Fleet PR: 91.4% → 95%+ after fix
🌳
Address Shading on SYS-007 (Marina East)
New construction adjacent to site is shading rows 3-4 during afternoon hours. Options: trim vegetation (if applicable), adjust tilt angle, or relocate affected panels.
📈 +14.8% performance recovery⏰ Site visit scheduled Apr 10
🧹
Establish Panel Cleaning Schedule
SYS-011 showing gradual output decline consistent with soiling. Recommend bi-weekly visual inspection and cleaning during dry season across fleet to prevent performance drift.
📈 Prevents 2-4% gradual PR loss💰 Low-cost preventive measure
