This is getting serious. I see also the contrast. On one side we speak here about 1% extra performance and on the other the entire installation has much higher risks of catching fire

Of course Cesar is in the loop. I am not surprised. I mean just pouring money in Solar is not enough. It's not a static asset.
What are you seeing with early-stage leads?
Do you think homeowners today prefer to research solar quietly on their own first, or do they still want to speak to someone early in the process? I’m seeing mixed behavior and I’m curious what you’re seeing in the field :)

One important factor to determine is how the installation is paid for. For example in the Netherlands, this can be paid by doing a mortgage extension and there are opportunities to buy through neighborhood associations. Personally, I don't have solar on my roof because the geometry made it too complex and with negative prices without storage it wasn't a good investment. In other countries such as Romania, EU subsidies can finance this. Personally, I would be comfortable in being taken by the hand in the process as good of an understanding I have of utility and C&I. Residential is another beast of a market.
Recycle? Upcycle? What are the options?
@Stefan Wippich mentioned the urgency for considering repowering to become a daily bread for many of us. My thoughts are going a step further though. The growth of obsolete modules and other PV equipment will be as exponential as the industry itself. Despite I see more and more talks and initiatives related to this topic, I can´t resist to think about what the future will be like in 2030 and later on. I don´t want to be the messenger of bad news. However! It might happen that we will be remembering the troubles with PET bottles with nostalgia, in comparison with the PV module disposal. I am curious about your opinions.

@Tobias Barg that is significant indeed. How many owners opt for this option vs inverter replacement?

@Tobias Barg amazing! I'm curious what it takes for someone to enter the inverter repair niche. Which skills specifically?
