This is a most excellent place for technology news and articles.
Is there a problem with the market being flooded with cheap not very good solar panels? Every single panel I looked at to put on my roof have all been of the highest quality I've not seen anyone try and hawk anything substandard.
Unless of course they're lying about what panels they're using but realistically I can't see that lasting for very long.
Yes, we do have that problem, but it's not the panels anyone puts on a roof. It's the cheap plastic shit manufacturers put on disposable consumer devices like pathway lighting or portable chargers.
I wouldn't put that cheap shit on my roof, but as solar adoption increases, capitalists are gonna capitalize.
