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 (-0.340 %/°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: AE Solar ME-132-660 or AE Solar AE ME-132BD-655?
According to our database: AE Solar ME-132-660 has higher module efficiency (21.27% vs 21.11%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AE Solar ME-132-660 and AE Solar AE ME-132BD-655?
AE Solar ME-132-660 has a module efficiency of 21.27%, while AE Solar AE ME-132BD-655 is 21.11%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar ME-132-660 use vs AE Solar AE ME-132BD-655?
AE Solar ME-132-660 uses PERC cells; AE Solar AE ME-132BD-655 uses PERC. 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 AE Solar ME-132-660 and AE Solar AE ME-132BD-655?
AE Solar ME-132-660 has a 30 years power warranty; AE Solar AE ME-132BD-655 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 AE Solar ME-132-660 and AE Solar AE ME-132BD-655 bifacial panels?
AE Solar AE ME-132BD-655 is bifacial (captures light from both faces); AE Solar ME-132-660 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
