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

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

SunEvo Solar SE6-66HBD-730W has a module efficiency of 23.50%, while SunEvo Solar SE6-66HBD-730 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-730W use vs SunEvo Solar SE6-66HBD-730?

SunEvo Solar SE6-66HBD-730W uses HJT 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.

Q: What is the warranty on SunEvo Solar SE6-66HBD-730W and SunEvo Solar SE6-66HBD-730?

SunEvo Solar SE6-66HBD-730W 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.

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

Both SunEvo Solar SE6-66HBD-730W 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.

The verdict

Identical on every published parameter

All 19 comparable parameters agree. Two records this alike are usually one panel sold under two names, or two bins of the same production line - decide on price and on who you would rather buy from.

What it means on a roof

Thirty years of production

Each panel's own declared degradation curve, at 1,200 kWh/kWp a year

Cell temperature

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.
