According to our database: **Renewsys DESERV Extreme 144X-600** has higher module efficiency (**23.26%** vs **23.18%**); **Emmvee E720HCBG 132-T** tolerates heat better (temp coeff **-0.290%/°C** vs **-0.292%/°C**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Emmvee E720HCBG 132-T and Renewsys DESERV Extreme 144X-600? **Emmvee E720HCBG 132-T** has a module efficiency of **23.18%**, while **Renewsys DESERV Extreme 144X-600** is **23.26%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Emmvee E720HCBG 132-T use vs Renewsys DESERV Extreme 144X-600? **Emmvee E720HCBG 132-T** uses **TOPCon** cells; **Renewsys DESERV Extreme 144X-600** 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 Emmvee E720HCBG 132-T and Renewsys DESERV Extreme 144X-600? **Emmvee E720HCBG 132-T** has a **30 years** power warranty; **Renewsys DESERV Extreme 144X-600** 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 Emmvee E720HCBG 132-T and Renewsys DESERV Extreme 144X-600 bifacial panels? Both **Emmvee E720HCBG 132-T** and **Renewsys DESERV Extreme 144X-600** 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 - [Emmvee E720HCBG 132-T vs Emmvee E720HCBG132-T](https://comparepv.com/compare/emmvee-e720hcbg-132-t/emmvee-e720hcbg132-t) - The same specification on paper - [Emmvee E720HCBG 132-T vs Emmvee E715HCBG 132-T](https://comparepv.com/compare/emmvee-e720hcbg-132-t/emmvee-e715hcbg-132-t) - The same specification on paper - [Emmvee E720HCBG 132-T vs Emmvee E715HCBG132-T](https://comparepv.com/compare/emmvee-e720hcbg-132-t/emmvee-e715hcbg132-t) - The same specification on paper - [Emmvee E720HCBG 132-T vs Emmvee E710HCBG 132-T](https://comparepv.com/compare/emmvee-e720hcbg-132-t/emmvee-e710hcbg-132-t) - 3 differences, the largest is module efficiency - [Emmvee E720HCBG 132-T vs Emmvee E710HCBG132-T](https://comparepv.com/compare/emmvee-e720hcbg-132-t/emmvee-e710hcbg132-t) - 3 differences, the largest is module efficiency - [Emmvee E720HCBG 132-T vs Emmvee E705HCBG 132-T](https://comparepv.com/compare/emmvee-e720hcbg-132-t/emmvee-e705hcbg-132-t) - 3 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/emmvee-e720hcbg-132-t/renewsys-deserv-extreme-144x-600 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.
