According to our database: **Jolywood JW-HD108N-R2-505** has higher module efficiency (**22.70%** 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-HD108N-R2-505 and Jolywood JW-HT108N-R3 445W? **Jolywood JW-HD108N-R2-505** has a module efficiency of **22.70%**, while **Jolywood JW-HT108N-R3 **445 W**** is **22.30%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Jolywood JW-HD108N-R2-505 use vs Jolywood JW-HT108N-R3 445W? **Jolywood JW-HD108N-R2-505** uses **TOPCon** cells; **Jolywood JW-HT108N-R3 **445 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-R2-505 and Jolywood JW-HT108N-R3 445W? **Jolywood JW-HD108N-R2-505** has a **30 years** power warranty; **Jolywood JW-HT108N-R3 **445 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-R2-505 and Jolywood JW-HT108N-R3 445W bifacial panels? **Jolywood JW-HD108N-R2-505** is bifacial (captures light from both faces); **Jolywood JW-HT108N-R3 **445 W**** is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath. ## Related comparisons - [Jolywood JW-HD108N-R2-505 vs Jolywood JW-HD108N-R2-525](https://comparepv.com/compare/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r2-505/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r2-525) - 4 differences, the largest is module efficiency - [Jolywood JW-HD108N-R2-505 vs Jolywood JW-HD108N-R2-520](https://comparepv.com/compare/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r2-505/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r2-520) - 3 differences, the largest is module efficiency - [Jolywood JW-HD108N-R2-505 vs Jolywood JW-HD108N-R2-515](https://comparepv.com/compare/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r2-505/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r2-515) - 3 differences, the largest is module efficiency - [Jolywood JW-HD108N-R2-505 vs Jolywood JW-HD108N-R2-510](https://comparepv.com/compare/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r2-505/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r2-510) - One difference: module efficiency - [Jolywood JW-HD108N-R2-505 vs Jolywood JW-HD108N-R2-500](https://comparepv.com/compare/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r2-505/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r2-500) - One difference: module efficiency - [Jolywood JW-HT108N-R3 445W vs Jolywood JW-HD108N-R3-460](https://comparepv.com/compare/jolywood-taizhou-solar-technology-co-ltd-jw-ht108n-r3-445w/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r3-460) - 6 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r2-505/jolywood-taizhou-solar-technology-co-ltd-jw-ht108n-r3-445w Not in this file, on the page: the thirty-year yield curve year by year at a cell temperature you pick and a written summary generated on request.
