Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be seasonal factors at play. Has this efficiency drop coincided with any particular weather patterns or seasonal changes?

Why it matters: Seasonal variations can significantly impact solar panel performance. Expected answer: There's been an unusually rainy season. Impact on approach: If confirmed, we'd need to factor in weather-related solutions.

• Considering potential system changes, have there been any recent updates to the monitoring or measurement systems used to track panel efficiency?

Why it matters: Changes in measurement systems could lead to false readings. Expected answer: No recent changes to monitoring systems. Impact on approach: If there were changes, we'd need to validate the new system's accuracy.

• Thinking about the panels themselves, has there been any change in the manufacturing process or sourcing of materials for the panels in the last few months?

Why it matters: Changes in production could directly affect panel quality and efficiency. Expected answer: A new supplier for a key component was introduced. Impact on approach: This would shift our focus to supply chain and quality control issues.

• Reflecting on maintenance practices, has there been any change in the cleaning or maintenance schedule for the solar panels?

Why it matters: Inadequate maintenance can lead to reduced efficiency. Expected answer: Maintenance schedules have remained consistent. Impact on approach: If changed, we'd need to reassess maintenance protocols.
