Haitai Solar JT710SLkB vs Haitai Solar JT715SLkB
VS
The verdict
Identical on every published parameter
All 18 comparable parameters agree, with 1 more left out because at least one datasheet does not publish it. 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
Declared first-year losses, with 0.40% a year afterwards assumed for both panels, 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: Haitai Solar JT710SLkB or Haitai Solar JT715SLkB?
According to our database: Haitai Solar JT715SLkB has higher module efficiency (23.00% vs 22.90%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Haitai Solar JT710SLkB and Haitai Solar JT715SLkB?
Haitai Solar JT710SLkB has a module efficiency of 22.90%, while Haitai Solar JT715SLkB is 23.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Haitai Solar JT710SLkB use vs Haitai Solar JT715SLkB?
Haitai Solar JT710SLkB uses HJT cells; Haitai Solar JT715SLkB 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 Haitai Solar JT710SLkB and Haitai Solar JT715SLkB?
Haitai Solar JT710SLkB has a 30 years power warranty; Haitai Solar JT715SLkB 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 Haitai Solar JT710SLkB and Haitai Solar JT715SLkB bifacial panels?
Both Haitai Solar JT710SLkB and Haitai Solar JT715SLkB 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.
