Q: What cell technology does Gamko New Energy GKA210N132-720W (series) use vs Gamko New Energy GKA210M400W (1/2*4*20)?

Gamko New Energy GKA210N132-720W (series) uses TOPCon cells; Gamko New Energy GKA210M400W (1/2*4*20) uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on Gamko New Energy GKA210N132-720W (series) and Gamko New Energy GKA210M400W (1/2*4*20)?

Gamko New Energy GKA210N132-720W (series) has a 30 years power warranty; Gamko New Energy GKA210M400W (1/2*4*20) has a 30 years power warranty. The power warranty guarantees a minimum percentage of rated output at the end of the warranty period (typically 80-87%). Product (materials) warranties are usually shorter.

Q: Are Gamko New Energy GKA210N132-720W (series) and Gamko New Energy GKA210M400W (1/2*4*20) bifacial panels?

Both Gamko New Energy GKA210N132-720W (series) and Gamko New Energy GKA210M400W (1/2*4*20) are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
