What it means on a roof

Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.290 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Questions about this pairing

Which panel is better: GL Solar HY-NT10/72GDF-600W or GL Solar HY-NT10/72GDF-605W?
According to our database: GL Solar HY-NT10/72GDF-605 W has higher module efficiency (23.40% vs 23.20%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of GL Solar HY-NT10/72GDF-600W and GL Solar HY-NT10/72GDF-605W?
GL Solar HY-NT10/72GDF-600 W has a module efficiency of 23.20%, while GL Solar HY-NT10/72GDF-605 W is 23.40%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does GL Solar HY-NT10/72GDF-600W use vs GL Solar HY-NT10/72GDF-605W?
GL Solar HY-NT10/72GDF-600 W uses TOPCon cells; GL Solar HY-NT10/72GDF-605 W uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.
What is the warranty on GL Solar HY-NT10/72GDF-600W and GL Solar HY-NT10/72GDF-605W?
GL Solar HY-NT10/72GDF-600 W has a 30 years power warranty; GL Solar HY-NT10/72GDF-605 W 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.
Are GL Solar HY-NT10/72GDF-600W and GL Solar HY-NT10/72GDF-605W bifacial panels?
Both GL Solar HY-NT10/72GDF-600 W and GL Solar HY-NT10/72GDF-605 W 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.
