What it means on a roof

Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.300 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

According to our database: Bauer Solar BS-475-120M10NHBB-GG has higher module efficiency (21.95% vs 21.72%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Bauer Solar BS-475-120M10NHBB-GG and Bauer Solar BS-470-120M10NHBB-GG?
Bauer Solar BS-475-120M10NHBB-GG has a module efficiency of 21.95%, 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-475-120M10NHBB-GG use vs Bauer Solar BS-470-120M10NHBB-GG?
Bauer Solar BS-475-120M10NHBB-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-475-120M10NHBB-GG and Bauer Solar BS-470-120M10NHBB-GG?
Bauer Solar BS-475-120M10NHBB-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-475-120M10NHBB-GG and Bauer Solar BS-470-120M10NHBB-GG bifacial panels?
Both Bauer Solar BS-475-120M10NHBB-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.
