KIOTO Solar KPV 450 Wp HC NE vs KIOTO Solar KPV 445Wp HC NE (G/G-TC)

Q: Which panel is better: KIOTO Solar KPV 450 Wp HC NE or KIOTO Solar KPV 445Wp HC NE (G/G-TC)?

According to our database: KIOTO Solar KPV 445Wp HC NE (G/G-TC) has higher module efficiency (22.79% vs 22.52%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of KIOTO Solar KPV 450 Wp HC NE and KIOTO Solar KPV 445Wp HC NE (G/G-TC)?

KIOTO Solar KPV 450 Wp HC NE has a module efficiency of 22.52%, while KIOTO Solar KPV 445Wp HC NE (G/G-TC) is 22.79%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does KIOTO Solar KPV 450 Wp HC NE use vs KIOTO Solar KPV 445Wp HC NE (G/G-TC)?

KIOTO Solar KPV 450 Wp HC NE uses TOPCon cells; KIOTO Solar KPV 445Wp 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 450 Wp HC NE and KIOTO Solar KPV 445Wp HC NE (G/G-TC)?

KIOTO Solar KPV 450 Wp HC NE has a 25 years power warranty; KIOTO Solar KPV 445Wp 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 450 Wp HC NE and KIOTO Solar KPV 445Wp HC NE (G/G-TC) bifacial panels?

Both KIOTO Solar KPV 450 Wp HC NE and KIOTO Solar KPV 445Wp HC NE (G/G-TC) are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
