When answering this question, emphasize your understanding of both the technical and practical aspects of maintaining solar panels. Discuss regular maintenance routines, such as cleaning panels to remove debris and checking for shading issues. Mention the importance of monitoring system performance through software tools and conducting periodic inspections to identify and rectify any issues promptly. Provide examples from your experience where you successfully maintained or improved the efficiency of solar panels. For instance, you might say:
"To ensure the efficiency and performance of installed solar panels, I conduct regular inspections and cleanings to remove any dirt or debris that could obstruct sunlight. I also use monitoring software to track the system's performance and quickly identify any drops in efficiency. For example, in my previous role, I noticed a significant drop in performance in one of the systems I managed. Upon inspection, I found that a tree had grown and was shading part of the panel. After trimming the tree, the system's performance improved immediately. Regular maintenance and prompt issue resolution are key to maintaining optimal performance."
