What the map shows
Three Chinese cities — Shenzhen, Shanghai and Beijing — top the list, reflecting China's dominance of solar manufacturing. But the next tier is striking: Latin America (São Paulo, Buenos Aires, Rio de Janeiro) and South/Southeast Asia (Jakarta, Lahore, Karachi) field huge installer and distribution bases serving fast-growing domestic markets. Europe and North America appear through engineering and trading hubs like Berlin, Madrid and Houston.
