Questions about this pairing

Which panel is better: AE Solar AE CME-132 720 or Gokin GK-4-78HGBD-780M?
According to our database: Gokin GK-4-78HGBD-780M has higher module efficiency (24.30% vs 23.21%); Gokin GK-4-78HGBD-780M 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.
What is the efficiency of AE Solar AE CME-132 720 and Gokin GK-4-78HGBD-780M?
AE Solar AE CME-132 720 has a module efficiency of 23.21%, while Gokin GK-4-78HGBD-780M is 24.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar AE CME-132 720 use vs Gokin GK-4-78HGBD-780M?
AE Solar AE CME-132 720 uses TOPCon cells; Gokin GK-4-78HGBD-780M uses Back Contact. 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 AE CME-132 720 and Gokin GK-4-78HGBD-780M?
AE Solar AE CME-132 720 has a 30 years power warranty; Gokin GK-4-78HGBD-780M 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 AE CME-132 720 and Gokin GK-4-78HGBD-780M bifacial panels?
Gokin GK-4-78HGBD-780M is bifacial (captures light from both faces); AE Solar AE CME-132 720 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
