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.

Questions about this pairing

Which panel is better: Jolywood JW-HD108N-R2-500 or Jolywood JW-HT108N-R3 450W?
According to our database: both panels are closely matched on key specs - the decision often comes down to price and local availability. See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Jolywood JW-HD108N-R2-500 and Jolywood JW-HT108N-R3 450W?
Jolywood JW-HD108N-R2-500 has a module efficiency of 22.50%, while Jolywood JW-HT108N-R3 450 W is 22.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jolywood JW-HD108N-R2-500 use vs Jolywood JW-HT108N-R3 450W?
Jolywood JW-HD108N-R2-500 uses TOPCon cells; Jolywood JW-HT108N-R3 450 W 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-HD108N-R2-500 and Jolywood JW-HT108N-R3 450W?
Jolywood JW-HD108N-R2-500 has a 30 years power warranty; Jolywood JW-HT108N-R3 450 W 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-HD108N-R2-500 and Jolywood JW-HT108N-R3 450W bifacial panels?
Jolywood JW-HD108N-R2-500 is bifacial (captures light from both faces); Jolywood JW-HT108N-R3 450 W is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
