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 (-0.280 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Which panel is better: Jolywood JW-HD96N-R2-455 or Jolywood JW-HD96N-R2-445?
According to our database: Jolywood JW-HD96N-R2-455 has higher module efficiency (22.80% vs 22.30%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Jolywood JW-HD96N-R2-455 and Jolywood JW-HD96N-R2-445?
Jolywood JW-HD96N-R2-455 has a module efficiency of 22.80%, while Jolywood JW-HD96N-R2-445 is 22.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jolywood JW-HD96N-R2-455 use vs Jolywood JW-HD96N-R2-445?
Jolywood JW-HD96N-R2-455 uses TOPCon cells; Jolywood JW-HD96N-R2-445 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 Jolywood JW-HD96N-R2-455 and Jolywood JW-HD96N-R2-445?
Jolywood JW-HD96N-R2-455 has a 30 years power warranty; Jolywood JW-HD96N-R2-445 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 Jolywood JW-HD96N-R2-455 and Jolywood JW-HD96N-R2-445 bifacial panels?
Both Jolywood JW-HD96N-R2-455 and Jolywood JW-HD96N-R2-445 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.
