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 (-0.240 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Questions about this pairing
Which panel is better: SunEvo Solar SE6-66HBD-725 or SunEvo Solar SE6-66HBD-745W?
According to our database: SunEvo Solar SE6-66HBD-745 W has higher module efficiency (24.00% vs 23.34%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of SunEvo Solar SE6-66HBD-725 and SunEvo Solar SE6-66HBD-745W?
SunEvo Solar SE6-66HBD-725 has a module efficiency of 23.34%, while SunEvo Solar SE6-66HBD-745 W is 24.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does SunEvo Solar SE6-66HBD-725 use vs SunEvo Solar SE6-66HBD-745W?
SunEvo Solar SE6-66HBD-725 uses HJT cells; SunEvo Solar SE6-66HBD-745 W 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-725 and SunEvo Solar SE6-66HBD-745W?
SunEvo Solar SE6-66HBD-725 has a 30 years power warranty; SunEvo Solar SE6-66HBD-745 W 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-725 and SunEvo Solar SE6-66HBD-745W bifacial panels?
Both SunEvo Solar SE6-66HBD-725 and SunEvo Solar SE6-66HBD-745 W 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.
