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-R3-450 and Jolywood JW-HT108N-R3 450W? **Jolywood JW-HD108N-R3-450** 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-R3-450 use vs Jolywood JW-HT108N-R3 450W? **Jolywood JW-HD108N-R3-450** 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-R3-450 and Jolywood JW-HT108N-R3 450W? **Jolywood JW-HD108N-R3-450** 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-R3-450 and Jolywood JW-HT108N-R3 450W bifacial panels? **Jolywood JW-HD108N-R3-450** 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. ## Related comparisons - [Jolywood JW-HD108N-R3-450 vs Jolywood JW-HD108N-R3-460](https://comparepv.com/compare/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r3-450/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r3-460) - 3 differences, the largest is module efficiency - [Jolywood JW-HD108N-R3-450 vs Jolywood JW-HT108N-R3 460W](https://comparepv.com/compare/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r3-450/jolywood-taizhou-solar-technology-co-ltd-jw-ht108n-r3-460w) - 6 differences, the largest is module efficiency - [Jolywood JW-HD108N-R3-450 vs Jolywood JW-HT108N-R3 455W](https://comparepv.com/compare/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r3-450/jolywood-taizhou-solar-technology-co-ltd-jw-ht108n-r3-455w) - 4 differences, the largest is weight per kwp - [Jolywood JW-HD108N-R3-450 vs Jolywood JW-HD108N-R3-455](https://comparepv.com/compare/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r3-450/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r3-455) - One difference: module efficiency - [Jolywood JW-HD108N-R3-450 vs Jolywood JW-HT108N-R3 445W](https://comparepv.com/compare/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r3-450/jolywood-taizhou-solar-technology-co-ltd-jw-ht108n-r3-445w) - 4 differences, the largest is weight per kwp - [Jolywood JW-HD108N-R3-450 vs Jolywood JW-HD108N-R3-445](https://comparepv.com/compare/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r3-450/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r3-445) - One difference: module efficiency --- Source: https://comparepv.com/compare/jolywood-taizhou-solar-technology-co-ltd-jw-hd108n-r3-450/jolywood-taizhou-solar-technology-co-ltd-jw-ht108n-r3-450w 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.
