Hello everyone, I would like to introduce myself as well. I am the CEO of WS Synergy BV, a company specialized in detecting faults in solar parks: Insulation faults Defective strings Burnt connectors We not only detect issues but also repair them. For the Dutch market, we perform Scope 12 repairs and issue repair statements. Additionally, we repair cable theft, replace defective panels, dismantle installations, and reinstall them. Where others stop, we go further and can often find the solution. Calin, thank you for opening this group. I hope to gain and share a lot of knowledge here, and advise or assist others whenever possible. If you have a problem, feel free to ask.

I have noticed that many of you are deep technical experts, so I might need to defend myself here. ;-) Anyways, I am curious, who of you is engaged with the sales in the sense that you need to convince another stakeholders that your solution (approach) is the best. And no - the cheapest does not need to mean the best.

I had several but I finally managed make substantial progress on the Handover to O&M Best Practices chapter. Share your win. Small, big or legendary, a win is a win.

Let me tell you about one of my most humbling moments in solar O&M. Back in 2021, I was managing an O&M service while also doing monitoring. During routine preventive maintenance, one of my technicians accidentally left 5 combiner boxes disconnected. Honestly? I get why it happened. Those boxes had the weirdest closing system, no LED indicators, and all the cables were buried. Easy mistake to make. But here's where it gets worse... The tech didn't check his work when he finished. I didn't verify it from the control room. We didn't even catch it in our end-of-month performance review. Two. Full. Months. It was only when I finally dug into the PR and energy performance index trends that I saw something was off. We pulled up the heat map and there it was—5 combiner boxes just sitting there, disconnected. Cue the emergency truck dispatch and some very awkward conversations. Here's what I learned (so you don't have to learn it the hard way): The real issue wasn't the technician's mistake. It was our process—or lack thereof. No combiner box monitoring. No systematic inverter comparison after maintenance. No immediate performance spot-checks. We got lucky. The PR impact was minimal. But that wake-up call changed everything about how we approach maintenance verification. Today, these mistakes don't happen anymore. Not because we became perfect, but because we built systems that catch human error before it costs time and money. What's your "oops, we missed that" moment? Share below—we're all learning together.
