Solar Panel Technologies Explained: Which Is Best for Assam?
- Mono PERC (Passivated Emitter and Rear Cell): Delivers 20%-22% efficiency. Excellent cost-to-performance ratio for residential rooftops.
- N-Type TOPCon (Tunnel Oxide Passivated Contact): Delivers 22%-24% efficiency. Superior low-light and monsoon generation, making it the best choice for cloudy climate in Assam.
- Bifacial Solar Modules: Generates power from both front and back sides (using reflected light off light-colored roofs), adding 10%-20% extra yield.
