According to our database: **Emmvee E715HCBG 132-T** has higher module efficiency (**23.02%** vs **21.87%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Emmvee E715HCBG 132-T and Emmvee ES65HCBT144-T? **Emmvee E715HCBG 132-T** has a module efficiency of **23.02%**, while **Emmvee ES65HCBT144-T** is **21.87%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Emmvee E715HCBG 132-T use vs Emmvee ES65HCBT144-T? **Emmvee E715HCBG 132-T** uses **TOPCon** cells; **Emmvee ES65HCBT144-T** 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 E715HCBG 132-T and Emmvee ES65HCBT144-T? **Emmvee E715HCBG 132-T** has a **30 years** power warranty; **Emmvee ES65HCBT144-T** 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 E715HCBG 132-T and Emmvee ES65HCBT144-T bifacial panels? Both **Emmvee E715HCBG 132-T** and **Emmvee ES65HCBT144-T** 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 E715HCBG 132-T vs Emmvee E720HCBG 132-T](https://comparepv.com/compare/emmvee-e715hcbg-132-t/emmvee-e720hcbg-132-t) - The same specification on paper - [Emmvee E715HCBG 132-T vs Emmvee E720HCBG132-T](https://comparepv.com/compare/emmvee-e715hcbg-132-t/emmvee-e720hcbg132-t) - The same specification on paper - [Emmvee E715HCBG 132-T vs Emmvee E715HCBG132-T](https://comparepv.com/compare/emmvee-e715hcbg-132-t/emmvee-e715hcbg132-t) - The same specification on paper - [Emmvee E715HCBG 132-T vs Emmvee E710HCBG 132-T](https://comparepv.com/compare/emmvee-e715hcbg-132-t/emmvee-e710hcbg-132-t) - The same specification on paper - [Emmvee E715HCBG 132-T vs Emmvee E710HCBG132-T](https://comparepv.com/compare/emmvee-e715hcbg-132-t/emmvee-e710hcbg132-t) - The same specification on paper - [Emmvee E715HCBG 132-T vs Emmvee E705HCBG 132-T](https://comparepv.com/compare/emmvee-e715hcbg-132-t/emmvee-e705hcbg-132-t) - 3 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/emmvee-e715hcbg-132-t/emmvee-es65hcbt144-t 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.
