According to our database: **Sunova TS-BG60(460)** has higher module efficiency (**21.32%** vs **21.08%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Sunova TS-BG60(455) and Sunova TS-BG60(460)? **Sunova TS-BG60(455)** has a module efficiency of **21.08%**, while **Sunova TS-BG60(460)** is **21.32%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Sunova TS-BG60(455) use vs Sunova TS-BG60(460)? **Sunova TS-BG60(455)** uses **PERC** cells; **Sunova TS-BG60(460)** uses **PERC**. 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 Sunova TS-BG60(455) and Sunova TS-BG60(460)? **Sunova TS-BG60(455)** has a **30 years** power warranty; **Sunova TS-BG60(460)** 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 Sunova TS-BG60(455) and Sunova TS-BG60(460) bifacial panels? Both **Sunova TS-BG60(455)** and **Sunova TS-BG60(460)** 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 - [Sunova TS-BG60(455) vs Sunova TS-BG60(450)](https://comparepv.com/compare/sunova-ts-bg60-455/sunova-ts-bg60-450) - One difference: module efficiency - [Sunova TS-BG60(455) vs Sunova TS-BG60(445)](https://comparepv.com/compare/sunova-ts-bg60-455/sunova-ts-bg60-445) - 3 differences, the largest is module efficiency - [Sunova TS-BG60(455) vs Sunova TS-BGT66(720)-G12](https://comparepv.com/compare/sunova-ts-bg60-455/sunova-ts-bgt66-720-g12) - 15 differences, the largest is module efficiency - [Sunova TS-BG60(455) vs Sunova TS-BWT66(720)-G12](https://comparepv.com/compare/sunova-ts-bg60-455/sunova-ts-bwt66-720-g12) - 15 differences, the largest is module efficiency - [Sunova TS-BG60(455) vs Sunova TS-BGT66(715)-G12](https://comparepv.com/compare/sunova-ts-bg60-455/sunova-ts-bgt66-715-g12) - 15 differences, the largest is module efficiency - [Sunova TS-BG60(455) vs Sunova TS-BWT66(715)-G12](https://comparepv.com/compare/sunova-ts-bg60-455/sunova-ts-bwt66-715-g12) - 15 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/sunova-ts-bg60-455/sunova-ts-bg60-460 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.
