SunEvo Solar SE6-66HBD-735W vs SunEvo Solar SE6-66HBD-730W

Q: Which panel is better: SunEvo Solar SE6-66HBD-735W or SunEvo Solar SE6-66HBD-730W?

According to our database: SunEvo Solar SE6-66HBD-735W has higher module efficiency (23.70% vs 23.50%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of SunEvo Solar SE6-66HBD-735W and SunEvo Solar SE6-66HBD-730W?

SunEvo Solar SE6-66HBD-735W has a module efficiency of 23.70%, while SunEvo Solar SE6-66HBD-730W is 23.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does SunEvo Solar SE6-66HBD-735W use vs SunEvo Solar SE6-66HBD-730W?

SunEvo Solar SE6-66HBD-735W uses HJT cells; SunEvo Solar SE6-66HBD-730W uses HJT. 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 SunEvo Solar SE6-66HBD-735W and SunEvo Solar SE6-66HBD-730W?

SunEvo Solar SE6-66HBD-735W has a 30 years power warranty; SunEvo Solar SE6-66HBD-730W 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.

Q: Are SunEvo Solar SE6-66HBD-735W and SunEvo Solar SE6-66HBD-730W bifacial panels?

Both SunEvo Solar SE6-66HBD-735W and SunEvo Solar SE6-66HBD-730W 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.
