EU regulators, the people who brought us lead-free solder, are going to love the "plumbate" part. It might as well be plutonium.
..except automotive, agricultural, aviation, health and so on basically anything that is even remotely critical is exempt.
The issue is whether solar panels containing lead are going to be the same as solder containing lead. I'm going to go with "no, not exactly" as solder is an OTC consumable that gets thrown around during DIY, fragments dropped on the floor where pets and toddlers can chew on them, it gets heated and inhaled, etc.
Solar panels are not quite the same. No doubt lead inside the sealed unit will cause implications for safe disposal; but then lots of things have special disposal, e.g. batteries.
It's only $44, shipped! It's enough lead to measurably lower the IQ of ten million infants.
The idea that out-of-control EU regulators prevent anyone, individual or industry, from acquiring and using elemental lead products is just another libertarian bugaboo that routinely pops up here on HN.
