KIOTO Solar KPV 450Wp HC vs KIOTO Solar KPV 440Wp HC NE (G/G-TC)

Q: Which panel is better: KIOTO Solar KPV 450Wp HC or KIOTO Solar KPV 440Wp HC NE (G/G-TC)?

According to our database: KIOTO Solar KPV 440Wp 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.

Q: What is the efficiency of KIOTO Solar KPV 450Wp HC and KIOTO Solar KPV 440Wp HC NE (G/G-TC)?

KIOTO Solar KPV 450Wp HC has a module efficiency of 22.53%, while KIOTO Solar KPV 440Wp HC NE (G/G-TC) is 22.53%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does KIOTO Solar KPV 450Wp HC use vs KIOTO Solar KPV 440Wp HC NE (G/G-TC)?

KIOTO Solar KPV 450Wp HC uses TOPCon cells; KIOTO Solar KPV 440Wp 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.

Q: What is the warranty on KIOTO Solar KPV 450Wp HC and KIOTO Solar KPV 440Wp HC NE (G/G-TC)?

KIOTO Solar KPV 450Wp HC has a 30 years power warranty; KIOTO Solar KPV 440Wp 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.

Q: Are KIOTO Solar KPV 450Wp HC and KIOTO Solar KPV 440Wp HC NE (G/G-TC) bifacial panels?

KIOTO Solar KPV 440Wp HC NE (G/G-TC) is bifacial (captures light from both faces); KIOTO Solar KPV 450Wp HC is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
