Questions about this pairing
Which panel is better: Bauer Solar BS-450-108M10HBT-GG or Bauer Solar BS-470-120M10NHBB-GG?
According to our database: Bauer Solar BS-450-108M10HBT-GG has higher module efficiency (22.50% vs 21.72%); Bauer Solar BS-450-108M10HBT-GG tolerates heat better (temp coeff -0.290%/°C vs -0.300%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Bauer Solar BS-450-108M10HBT-GG and Bauer Solar BS-470-120M10NHBB-GG?
Bauer Solar BS-450-108M10HBT-GG has a module efficiency of 22.50%, while Bauer Solar BS-470-120M10NHBB-GG is 21.72%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Bauer Solar BS-450-108M10HBT-GG use vs Bauer Solar BS-470-120M10NHBB-GG?
Bauer Solar BS-450-108M10HBT-GG uses TOPCon cells; Bauer Solar BS-470-120M10NHBB-GG 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 Bauer Solar BS-450-108M10HBT-GG and Bauer Solar BS-470-120M10NHBB-GG?
Bauer Solar BS-450-108M10HBT-GG has a 30 years power warranty; Bauer Solar BS-470-120M10NHBB-GG 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 Bauer Solar BS-450-108M10HBT-GG and Bauer Solar BS-470-120M10NHBB-GG bifacial panels?
Both Bauer Solar BS-450-108M10HBT-GG and Bauer Solar BS-470-120M10NHBB-GG 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.
