According to our database: **Sunpro Power SP**620 W**-210R-132DS** has higher module efficiency (**22.95%** vs **22.77%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Sunpro Power SP-96DSN455 and Sunpro Power SP620W-210R-132DS? **Sunpro Power SP-96DSN455** has a module efficiency of **22.77%**, while **Sunpro Power SP**620 W**-210R-132DS** is **22.95%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Sunpro Power SP-96DSN455 use vs Sunpro Power SP620W-210R-132DS? **Sunpro Power SP-96DSN455** uses **HJT** cells; **Sunpro Power SP**620 W**-210R-132DS** 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 Sunpro Power SP-96DSN455 and Sunpro Power SP620W-210R-132DS? **Sunpro Power SP-96DSN455** has a **30 years** power warranty; **Sunpro Power SP**620 W**-210R-132DS** 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 Sunpro Power SP-96DSN455 and Sunpro Power SP620W-210R-132DS bifacial panels? Both **Sunpro Power SP-96DSN455** and **Sunpro Power SP**620 W**-210R-132DS** are bifacial - they capture reflected light from the ground, which can add 5**-15%** more annual energy on ground-mount or elevated rooftop installations with a light surface beneath. ## Related comparisons - [Sunpro Power SP-96DSN455 vs Sunpro Power SP630W-210R-132DS](https://comparepv.com/compare/sunpro-sp-96dsn455/sunpro-sp630w-210r-132ds) - 12 differences, the largest is rated power - [Sunpro Power SP-96DSN455 vs Sunpro Power SP610W-210R-132DS](https://comparepv.com/compare/sunpro-sp-96dsn455/sunpro-sp610w-210r-132ds) - 9 differences, the largest is rated power - [Sunpro Power SP-96DSN455 vs Sunpro Power SP600W-210R-132DS](https://comparepv.com/compare/sunpro-sp-96dsn455/sunpro-sp600w-210r-132ds) - 11 differences, the largest is rated power - [Sunpro Power SP-96DSN455 vs Sunpro Power SP-96DSB460](https://comparepv.com/compare/sunpro-sp-96dsn455/sunpro-sp-96dsb460) - One difference: module efficiency - [Sunpro Power SP-96DSN455 vs Sunpro Power SP-96DSN460](https://comparepv.com/compare/sunpro-sp-96dsn455/sunpro-sp-96dsn460) - One difference: module efficiency - [Sunpro Power SP-96DSN455 vs Sunpro Power SP-96DSB455](https://comparepv.com/compare/sunpro-sp-96dsn455/sunpro-sp-96dsb455) - The same specification on paper --- Source: https://comparepv.com/compare/sunpro-sp-96dsn455/sunpro-sp620w-210r-132ds 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.
