Questions about this pairing

Which panel is better: SunEvo Solar SE6-66HBD-720W or SunEvo Solar SE6-66HBD-730?
According to our database: SunEvo Solar SE6-66HBD-730 has higher module efficiency (23.50% vs 23.20%); SunEvo Solar SE6-66HBD-730 tolerates heat better (temp coeff -0.240%/°C vs -0.280%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of SunEvo Solar SE6-66HBD-720W and SunEvo Solar SE6-66HBD-730?
SunEvo Solar SE6-66HBD-720 W has a module efficiency of 23.20%, while SunEvo Solar SE6-66HBD-730 is 23.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does SunEvo Solar SE6-66HBD-720W use vs SunEvo Solar SE6-66HBD-730?
SunEvo Solar SE6-66HBD-720 W uses TOPCon cells; SunEvo Solar SE6-66HBD-730 uses HJT. 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 SunEvo Solar SE6-66HBD-720W and SunEvo Solar SE6-66HBD-730?
SunEvo Solar SE6-66HBD-720 W has a 30 years power warranty; SunEvo Solar SE6-66HBD-730 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 SunEvo Solar SE6-66HBD-720W and SunEvo Solar SE6-66HBD-730 bifacial panels?
Both SunEvo Solar SE6-66HBD-720 W and SunEvo Solar SE6-66HBD-730 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.

Every figure here is from the manufacturers' own datasheets - a dash means the value is not published, never an estimate. The thirty-year projection and the temperature scenarios are calculations from those figures, and each states its assumption above.
