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 (-0.260 %/°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: Sharp GSD8K66H-740WT or PVolution PVN720-M12TCBB?
According to our database: Sharp GSD8K66H-740WT has higher module efficiency (23.82% vs 23.18%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Sharp GSD8K66H-740WT and PVolution PVN720-M12TCBB?
Sharp GSD8K66H-740WT has a module efficiency of 23.82%, while PVolution PVN720-M12TCBB is 23.18%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Sharp GSD8K66H-740WT use vs PVolution PVN720-M12TCBB?
Sharp GSD8K66H-740WT uses HJT cells; PVolution PVN720-M12TCBB uses HJT. 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 Sharp GSD8K66H-740WT and PVolution PVN720-M12TCBB?
Sharp GSD8K66H-740WT has a 30 years power warranty; PVolution PVN720-M12TCBB 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 Sharp GSD8K66H-740WT and PVolution PVN720-M12TCBB bifacial panels?
Both Sharp GSD8K66H-740WT and PVolution PVN720-M12TCBB 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.
