According to our database: **Renewsys DESERV Extreme 144X-600** has higher module efficiency (**23.26%** vs **23.06%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Renewsys DESERV Extreme 144X-595 and Renewsys DESERV Extreme 144X-600? **Renewsys DESERV Extreme 144X-595** has a module efficiency of **23.06%**, 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 Renewsys DESERV Extreme 144X-595 use vs Renewsys DESERV Extreme 144X-600? **Renewsys DESERV Extreme 144X-595** 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 Renewsys DESERV Extreme 144X-595 and Renewsys DESERV Extreme 144X-600? **Renewsys DESERV Extreme 144X-595** 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 Renewsys DESERV Extreme 144X-595 and Renewsys DESERV Extreme 144X-600 bifacial panels? Both **Renewsys DESERV Extreme 144X-595** 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 - [Renewsys DESERV Extreme 144X-595 vs Renewsys DESERV Extreme 144X-610](https://comparepv.com/compare/renewsys-deserv-extreme-144x-595/renewsys-deserv-extreme-144x-610) - 3 differences, the largest is module efficiency - [Renewsys DESERV Extreme 144X-595 vs Renewsys DESERV Extreme 144X-605](https://comparepv.com/compare/renewsys-deserv-extreme-144x-595/renewsys-deserv-extreme-144x-605) - 3 differences, the largest is module efficiency - [Renewsys DESERV Extreme 144X-595 vs Renewsys DESERV Extreme 144X-590](https://comparepv.com/compare/renewsys-deserv-extreme-144x-595/renewsys-deserv-extreme-144x-590) - The same specification on paper - [Renewsys DESERV Extreme 144X-595 vs Renewsys DESERV Extreme 144X-585](https://comparepv.com/compare/renewsys-deserv-extreme-144x-595/renewsys-deserv-extreme-144x-585) - 3 differences, the largest is module efficiency - [Renewsys DESERV Extreme 144X-595 vs Renewsys DESERV Extreme 144X-580](https://comparepv.com/compare/renewsys-deserv-extreme-144x-595/renewsys-deserv-extreme-144x-580) - 3 differences, the largest is module efficiency - [Renewsys DESERV Extreme 144X-595 vs Renewsys DESERV Extreme 144X-575](https://comparepv.com/compare/renewsys-deserv-extreme-144x-595/renewsys-deserv-extreme-144x-575) - 5 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/renewsys-deserv-extreme-144x-595/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.
