Questions about this pairing

Which panel is better: Haitai Solar JT690SLkB or Haitai Solar CETC-455TR(GDF)/96?
According to our database: Haitai Solar CETC-455TR(GDF)/96 has higher module efficiency (22.77% vs 22.20%); Haitai Solar JT690SLkB tolerates heat better (temp coeff -0.240%/°C vs -0.300%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Haitai Solar JT690SLkB and Haitai Solar CETC-455TR(GDF)/96?
Haitai Solar JT690SLkB has a module efficiency of 22.20%, while Haitai Solar CETC-455TR(GDF)/96 is 22.77%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Haitai Solar JT690SLkB use vs Haitai Solar CETC-455TR(GDF)/96?
Haitai Solar JT690SLkB uses HJT cells; Haitai Solar CETC-455TR(GDF)/96 uses TOPCon. 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 JT690SLkB and Haitai Solar CETC-455TR(GDF)/96?
Haitai Solar JT690SLkB has a 30 years power warranty; Haitai Solar CETC-455TR(GDF)/96 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 JT690SLkB and Haitai Solar CETC-455TR(GDF)/96 bifacial panels?
Both Haitai Solar JT690SLkB and Haitai Solar CETC-455TR(GDF)/96 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.
