Questions about this pairing

Which panel is better: AUSTA ENERGY ODA730-33V-MHD or AUSTA ENERGY ODA435-27V-MHD?
According to our database: AUSTA ENERGY ODA730-33V-MHD has higher module efficiency (23.50% vs 22.28%); AUSTA ENERGY ODA730-33V-MHD tolerates heat better (temp coeff -0.223%/°C vs -0.290%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AUSTA ENERGY ODA730-33V-MHD and AUSTA ENERGY ODA435-27V-MHD?
AUSTA ENERGY ODA730-33V-MHD has a module efficiency of 23.50%, while AUSTA ENERGY ODA435-27V-MHD is 22.28%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AUSTA ENERGY ODA730-33V-MHD use vs AUSTA ENERGY ODA435-27V-MHD?
AUSTA ENERGY ODA730-33V-MHD uses HJT cells; AUSTA ENERGY ODA435-27V-MHD 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 AUSTA ENERGY ODA730-33V-MHD and AUSTA ENERGY ODA435-27V-MHD?
AUSTA ENERGY ODA730-33V-MHD has a 30 years power warranty; AUSTA ENERGY ODA435-27V-MHD 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 AUSTA ENERGY ODA730-33V-MHD and AUSTA ENERGY ODA435-27V-MHD bifacial panels?
Both AUSTA ENERGY ODA730-33V-MHD and AUSTA ENERGY ODA435-27V-MHD 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.
