According to our database: **Sunpro Power SP-96DSN455** has higher module efficiency (**22.77%** vs **22.02%**); **Sunpro Power SP-96DSN455** tolerates heat better (temp coeff **-0.240%/°C** vs **-0.300%/°C**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Resun Solar RS8V-M TOPCON-430W and Sunpro Power SP-96DSN455? **Resun Solar RS8V-M TOPCON-**430 W**** has a module efficiency of **22.02%**, while **Sunpro Power SP-96DSN455** is **22.77%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Resun Solar RS8V-M TOPCON-430W use vs Sunpro Power SP-96DSN455? **Resun Solar RS8V-M TOPCON-**430 W**** uses **TOPCon** cells; **Sunpro Power SP-96DSN455** uses **HJT**. 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 Resun Solar RS8V-M TOPCON-430W and Sunpro Power SP-96DSN455? **Resun Solar RS8V-M TOPCON-**430 W**** has a **30 years** power warranty; **Sunpro Power SP-96DSN455** 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 Resun Solar RS8V-M TOPCON-430W and Sunpro Power SP-96DSN455 bifacial panels? **Sunpro Power SP-96DSN455** is bifacial (captures light from both faces); **Resun Solar RS8V-M TOPCON-**430 W**** is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath. ## Related comparisons - [Resun Solar RS8V-M TOPCON-430W vs Resun Solar RS8V-M-DG](https://comparepv.com/compare/resun-solar-rs8v-m-topcon-430w/resun-solar-rs8v-m-dg) - 8 differences, the largest is module efficiency - [Resun Solar RS8V-M TOPCON-430W vs Resun Solar RS8V-M-DG-440](https://comparepv.com/compare/resun-solar-rs8v-m-topcon-430w/resun-solar-rs8v-m-dg-440) - 8 differences, the largest is module efficiency - [Resun Solar RS8V-M TOPCON-430W vs Resun Solar RS8V-M-435W FULL BLACK](https://comparepv.com/compare/resun-solar-rs8v-m-topcon-430w/resun-solar-rs8v-m-435w-full-black) - 3 differences, the largest is temperature coefficient - [Resun Solar RS8V-M TOPCON-430W vs Resun Solar RS8V-M-DG-435](https://comparepv.com/compare/resun-solar-rs8v-m-topcon-430w/resun-solar-rs8v-m-dg-435) - 6 differences, the largest is product warranty - [Resun Solar RS8V-M TOPCON-430W vs Resun Solar RS8V-M TOPCON-435W](https://comparepv.com/compare/resun-solar-rs8v-m-topcon-430w/resun-solar-rs8v-m-topcon-435w) - One difference: module efficiency - [Resun Solar RS8V-M TOPCON-430W vs Resun Solar RS8V435M-FB](https://comparepv.com/compare/resun-solar-rs8v-m-topcon-430w/resun-solar-rs8v435m-fb) - 4 differences, the largest is temperature coefficient --- Source: https://comparepv.com/compare/resun-solar-rs8v-m-topcon-430w/sunpro-sp-96dsn455 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.
