Solar Panel Efficiency in 2025: TOPCon vs. HJT Technology for Indian Factories
For factory owners in India, the equation is simple: higher solar efficiency equals lower electricity bills. But in 2025, the technology landscape has shifted. The old standard (PERC panels) is fading, replaced by two heavyweights: TOPCon (Tunnel Oxide Passivated Contact) and HJT (Heterojunction) technology.
