Questions about this pairing

Which panel is better: KIOTO Solar KPV 440 Wp HCB or KIOTO Solar KPV 450 Wp HC NE?
According to our database: KIOTO Solar KPV 450 Wp HC NE has higher module efficiency (22.52% vs 22.02%); KIOTO Solar KPV 450 Wp HC NE 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 450 Wp HC NE?
KIOTO Solar KPV 440 Wp HCB has a module efficiency of 22.02%, while KIOTO Solar KPV 450 Wp HC NE 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 450 Wp HC NE?
KIOTO Solar KPV 440 Wp HCB uses TOPCon cells; KIOTO Solar KPV 450 Wp HC NE 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 450 Wp HC NE?
KIOTO Solar KPV 440 Wp HCB has a 30 years power warranty; KIOTO Solar KPV 450 Wp HC NE 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 450 Wp HC NE bifacial panels?
KIOTO Solar KPV 450 Wp HC NE 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.
