In 2019, the Netherlands tested a 1,312-foot highway noise barrier with two-sided solar panels; it generated 325.5 MWh over 18 months

Dutch engineers transformed highway sound walls into solar power generators. These innovative walls produced significant electricity during an eighteen-month test period. The bifacial solar glass panels generated power from both sides, maximizing energy capture. This project demonstrated a novel approach to clean energy generation without using new land. Similar opportunities exist in America for repurposing existing infrastructure.
