A 2022 University of California study found lead concentrations 12x higher than EPA limits in water collected from older solar arrays. Yikes! It's like your panels are mixing a techy version of Long Island Iced Tea - but you definitely don't want to drink this cocktail. While these photovoltaic systems need occasional cleaning, their operation demonstrates remarkable water conservation benefits. . However, there are still lingering concerns over the safety of drinking water when solar panel systems are installed near bodies of water. That "free" rainwater looks tempting, especially during droughts. 6 (a) (3) (ii)) or 40 CFR Section 261. Despite what it says on the dodgey parts of the internet I think panels are just as safe as metal tanks which are lined with plastic (the corrugated Lysaght material is called aquaplate) or poly tanks for that matter.
