Continued thread
As for lead in #solar panels, it gets discussed in this 5 year old article:
https://www.pv-magazine.com/2019/10/26/the-weekend-read-a-lead-free-future-for-solar-pv/
"In spite of this, a typical 60-cell crystalline silicon solar module produced today contains up to 12 grams of lead. This lead is primarily found within the ribbon coating and soldering paste used to connect cells together."
There are panels that are entirely free of lead, though. Seems to be a price thing.
pv magazine InternationalThe weekend read: A lead-free future for solar PVLead plays an important role in crystalline silicon module manufacturing when it comes to cell interconnection. But even in small amounts, the presence of this toxic material in a PV module could be viewed as a black mark against the industry’s sustainable credentials. Alternatives are available, but it seems the price is not yet right for broader uptake.
There are no hazardous materials in crystaline #solar modules. Well, there's tin from soldering, but that's it.
Your standard solar module consists of:
- A glass panel and aluminium frame (80%-90% of weight)
- A plastic sheet on the back, or another glass panel
- Rows of solar cells glued onto the back panel, soldered together and connected to a junction box.
