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: FuturaSun FU 575 MV or FuturaSun FU 580 MV?
According to our database: FuturaSun FU 580 MV has higher module efficiency (22.40% vs 22.20%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of FuturaSun FU 575 MV and FuturaSun FU 580 MV?
FuturaSun FU 575 MV has a module efficiency of 22.20%, while FuturaSun FU 580 MV is 22.40%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does FuturaSun FU 575 MV use vs FuturaSun FU 580 MV?
FuturaSun FU 575 MV uses TOPCon cells; FuturaSun FU 580 MV 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 FuturaSun FU 575 MV and FuturaSun FU 580 MV?
FuturaSun FU 575 MV has a 30 years power warranty; FuturaSun FU 580 MV 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 FuturaSun FU 575 MV and FuturaSun FU 580 MV bifacial panels?
Both FuturaSun FU 575 MV and FuturaSun FU 580 MV 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.
