Questions about this pairing

Which panel is better: KIOTO Solar KPV 440 Wp HCB or KIOTO Solar KPV 450Wp HC NE (G/G-TC)?
According to our database: KIOTO Solar KPV 450 Wp HC NE (G/G-TC) has higher module efficiency (22.52% vs 22.02%); KIOTO Solar KPV 450 Wp HC NE (G/G-TC) tolerates heat better (temp coeff -0.300%/°C vs -0.320%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of KIOTO Solar KPV 440 Wp HCB and KIOTO Solar KPV 450Wp HC NE (G/G-TC)?
KIOTO Solar KPV 440 Wp HCB has a module efficiency of 22.02%, while KIOTO Solar KPV 450 Wp HC NE (G/G-TC) is 22.52%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does KIOTO Solar KPV 440 Wp HCB use vs KIOTO Solar KPV 450Wp HC NE (G/G-TC)?
KIOTO Solar KPV 440 Wp HCB uses TOPCon cells; KIOTO Solar KPV 450 Wp HC NE (G/G-TC) 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 KIOTO Solar KPV 440 Wp HCB and KIOTO Solar KPV 450Wp HC NE (G/G-TC)?
KIOTO Solar KPV 440 Wp HCB has a 30 years power warranty; KIOTO Solar KPV 450 Wp HC NE (G/G-TC) has a 25 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 KIOTO Solar KPV 440 Wp HCB and KIOTO Solar KPV 450Wp HC NE (G/G-TC) bifacial panels?
KIOTO Solar KPV 450 Wp HC NE (G/G-TC) is bifacial (captures light from both faces); KIOTO Solar KPV 440 Wp HCB is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
