GL Solar 3SHBGH-C#-640 vs GL Solar HY-NT10/72GDF-600W

Q: Which panel is better: GL Solar 3SHBGH-C#-640 or GL Solar HY-NT10/72GDF-600W?

According to our database: GL Solar HY-NT10/72GDF-600W has higher module efficiency (23.20% vs 22.60%); GL Solar 3SHBGH-C#-640 tolerates heat better (temp coeff -0.260%/°C vs -0.290%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of GL Solar 3SHBGH-C#-640 and GL Solar HY-NT10/72GDF-600W?

GL Solar 3SHBGH-C#-640 has a module efficiency of 22.60%, while GL Solar HY-NT10/72GDF-600W is 23.20%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does GL Solar 3SHBGH-C#-640 use vs GL Solar HY-NT10/72GDF-600W?

GL Solar 3SHBGH-C#-640 uses HJT cells; GL Solar HY-NT10/72GDF-600W 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 GL Solar 3SHBGH-C#-640 and GL Solar HY-NT10/72GDF-600W?

GL Solar 3SHBGH-C#-640 has a 30 years power warranty; GL Solar HY-NT10/72GDF-600W 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 GL Solar 3SHBGH-C#-640 and GL Solar HY-NT10/72GDF-600W bifacial panels?

Both GL Solar 3SHBGH-C#-640 and GL Solar HY-NT10/72GDF-600W 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.
