Solar modules now selling for less than €0.06/W in Europe

This is a most excellent place for technology news and articles.
A hundred euro is quite a difference. Didn't expect it to be that much, tbh.
The only consolation is that, with the discounter sets, you will get something that has been tried and tested and everything is according to the relevant technical standards. Should be, anyway.
What I'd like best is to just buy them at a regular store. Not do onlines shopping in the first place. (And then figure out how to return something that was delivered with some special service. I guess you can't drop them off at the next DHL place, like with the other Amazon stuff.)
But I guess they're fine, too. The Amazon sellers have the same "brand" inverters like Ecoflow and Growatt.
