GL Solar HY-NT10/72GDF-590W vs GL Solar 3SHBGH-C#-640

Q: Which panel is better: GL Solar HY-NT10/72GDF-590W or GL Solar 3SHBGH-C#-640?

According to our database: GL Solar HY-NT10/72GDF-590W has higher module efficiency (22.80% 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 HY-NT10/72GDF-590W and GL Solar 3SHBGH-C#-640?

GL Solar HY-NT10/72GDF-590W has a module efficiency of 22.80%, while GL Solar 3SHBGH-C#-640 is 22.60%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does GL Solar HY-NT10/72GDF-590W use vs GL Solar 3SHBGH-C#-640?

GL Solar HY-NT10/72GDF-590W uses TOPCon cells; GL Solar 3SHBGH-C#-640 uses HJT. 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 HY-NT10/72GDF-590W and GL Solar 3SHBGH-C#-640?

GL Solar HY-NT10/72GDF-590W has a 30 years power warranty; GL Solar 3SHBGH-C#-640 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 HY-NT10/72GDF-590W and GL Solar 3SHBGH-C#-640 bifacial panels?

Both GL Solar HY-NT10/72GDF-590W and GL Solar 3SHBGH-C#-640 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.
