According to our database: **Astronergy CHSM66RN(DG)/F-BH-650** has higher module efficiency (**24.10%** vs **22.40%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Astronergy CHSM66RN(DG)/F-BH-605 and Astronergy CHSM66RN(DG)/F-BH-650? **Astronergy CHSM66RN(DG)/F-BH-605** has a module efficiency of **22.40%**, while **Astronergy CHSM66RN(DG)/F-BH-650** is **24.10%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Astronergy CHSM66RN(DG)/F-BH-605 use vs Astronergy CHSM66RN(DG)/F-BH-650? **Astronergy CHSM66RN(DG)/F-BH-605** uses **TOPCon** cells; **Astronergy CHSM66RN(DG)/F-BH-650** 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 Astronergy CHSM66RN(DG)/F-BH-605 and Astronergy CHSM66RN(DG)/F-BH-650? **Astronergy CHSM66RN(DG)/F-BH-605** has a **30 years** power warranty; **Astronergy CHSM66RN(DG)/F-BH-650** 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 Astronergy CHSM66RN(DG)/F-BH-605 and Astronergy CHSM66RN(DG)/F-BH-650 bifacial panels? Both **Astronergy CHSM66RN(DG)/F-BH-605** and **Astronergy CHSM66RN(DG)/F-BH-650** 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 - [Astronergy CHSM66RN(DG)/F-BH-605 vs Astronergy CHSM66RN(DG)/F-BQ-670](https://comparepv.com/compare/astronergy-chsm66rn-dg-f-bh-605/astronergy-chsm66rn-dg-f-bq-670) - 10 differences, the largest is module efficiency - [Astronergy CHSM66RN(DG)/F-BH-605 vs Astronergy CHSM66RN(DG)/F-BQ](https://comparepv.com/compare/astronergy-chsm66rn-dg-f-bh-605/astronergy-chsm66rn-dg-f-bq) - 10 differences, the largest is module efficiency - [Astronergy CHSM66RN(DG)/F-BH-605 vs Astronergy CHSM66RN(DG)/F-BQ-665](https://comparepv.com/compare/astronergy-chsm66rn-dg-f-bh-605/astronergy-chsm66rn-dg-f-bq-665) - 10 differences, the largest is module efficiency - [Astronergy CHSM66RN(DG)/F-BH-605 vs Astronergy CHSM66RN(DG)/F-BQ-660](https://comparepv.com/compare/astronergy-chsm66rn-dg-f-bh-605/astronergy-chsm66rn-dg-f-bq-660) - 10 differences, the largest is module efficiency - [Astronergy CHSM66RN(DG)/F-BH-605 vs Astronergy CHSM66RN(DG)/F-BQ-655](https://comparepv.com/compare/astronergy-chsm66rn-dg-f-bh-605/astronergy-chsm66rn-dg-f-bq-655) - 10 differences, the largest is module efficiency - [Astronergy CHSM66RN(DG)/F-BH-605 vs Astronergy CHSM66RN(DG)/F-BH-650W](https://comparepv.com/compare/astronergy-chsm66rn-dg-f-bh-605/astronergy-chint-new-energy-technology-co-ltd-chsm66rn-dg-f-bh-650w) - 9 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/astronergy-chsm66rn-dg-f-bh-605/astronergy-chsm66rn-dg-f-bh-650 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.
