10. FAQ: Professional Terms & Technical Guidance

Q1: What is the “n-type” silicon and its benefit for the LONGi 585-620W Hi-MO7 Bifacial Half cell Solar Panel for Home?

A1: n-type silicon is a type of crystalline silicon where extra electrons serve as majority carriers, resulting in lower light-induced degradation (LID) and higher efficiency than p-type cells, allowing more stable output over time.

Q2: What does “bifacial gain” mean?

A2: “Bifacial gain” is the percentage of extra electricity generated thanks to light entering the cell from the rear side of the panel. The LONGi Hi-MO7 achieves up to 30% bifacial gain under optimal conditions (e.g., over white concrete or snowy rooftops).

Q3: What makes “dual-glass” structure superior for home panels?

A3: Dual-glass, or glass-glass construction, uses two layers of tempered glass instead of a polymer backsheet, offering higher rigidity, enhanced fire resistance, less PID, and a 30+ year lifespan even in harsh outdoor environments.

Q4: What is “TOPCon” cell technology?

A4: TOPCon (“Tunnel Oxide Passivated Contact”) is a leading-edge photovoltaic cell passivation method, boosting efficiency and open-circuit voltage, and enabling better performance in low-light and partial-shade conditions.

Q5: Which standards are met by the LONGi 585-620W Hi-MO7 Bifacial Half cell Solar Panel for Home?

A5: Complies with IEC 61215, IEC 61730, UL 1703 (safety & performance), certified against IEC 61701 (salt mist), IEC 62716 (ammonia), and manufactured under ISO 9001/14001/45001 management.

Q6: What is a “multi-busbar” (MBB) cell?

A6: An MBB cell uses multiple thin metal collectors (busbars) to reduce resistive losses and increase output, improving reliability and reducing risks of hot spots or microcracks.

Q7: What’s the maximum system voltage & grid compatibility?

A7: The panel supports system voltages up to 1500V DC, compatible with all global grid-tie string inverters for home and commercial rooftops.
