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 JT705SLkB?
According to our database: Haitai Solar JT710SLkB has higher module efficiency (22.90% vs 22.70%). 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 JT705SLkB?
Haitai Solar JT710SLkB has a module efficiency of 22.90%, while Haitai Solar JT705SLkB is 22.70%. 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 JT705SLkB?
Haitai Solar JT710SLkB uses HJT cells; Haitai Solar JT705SLkB 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 JT705SLkB?
Haitai Solar JT710SLkB has a 30 years power warranty; Haitai Solar JT705SLkB 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 JT705SLkB bifacial panels?
Both Haitai Solar JT710SLkB and Haitai Solar JT705SLkB 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.
