Monocrystalline silicon panels (most common) contain trace lead solder. Amorphous/thin-film panels may contain cadmium telluride. Heat cycling (sun exposure + cooling) gradually degrades panel efficiency. Primary consumer concern is efficiency claims exceeding real-world performance (marketing vs physics). Chemical exposure is negligible during normal use (sealed behind tempered glass).","synthesis":{"derived_risk_level":"high","synthesis_confidence":0.744,"synthesis_method":"compound_composition","context_used":"human_adult","context_source":"product_users","exposure_modifier":0.85,"vulnerability_escalated":false,"escalation_reason":null,"compounds_resolved":1,"compounds_total":1,"synthesis_date":"2026-05-09","synthesis_version":"1.2.0","methodology_note":"exposure_modifier and adjusted_magnitude are computed from ALETHEIA-calibrated heuristics (route × duration × frequency multipliers, clamped to [0.5, 1.4]).
