Jolywood JW-HD108N-R2-520 vs Jolywood JW-HT108N-R3 445W

Q: Which panel is better: Jolywood JW-HD108N-R2-520 or Jolywood JW-HT108N-R3 445W?

According to our database: Jolywood JW-HD108N-R2-520 has higher module efficiency (23.40% vs 22.30%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Jolywood JW-HD108N-R2-520 and Jolywood JW-HT108N-R3 445W?

Jolywood JW-HD108N-R2-520 has a module efficiency of 23.40%, while Jolywood JW-HT108N-R3 445W is 22.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Jolywood JW-HD108N-R2-520 use vs Jolywood JW-HT108N-R3 445W?

Jolywood JW-HD108N-R2-520 uses TOPCon cells; Jolywood JW-HT108N-R3 445W uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on Jolywood JW-HD108N-R2-520 and Jolywood JW-HT108N-R3 445W?

Jolywood JW-HD108N-R2-520 has a 30 years power warranty; Jolywood JW-HT108N-R3 445W 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.

Q: Are Jolywood JW-HD108N-R2-520 and Jolywood JW-HT108N-R3 445W bifacial panels?

Jolywood JW-HD108N-R2-520 is bifacial (captures light from both faces); Jolywood JW-HT108N-R3 445W is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.

What it means on a roof

Thirty years of production

Each panel's own declared degradation curve, at 1,200 kWh/kWp a year

Cell temperature

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.
