According to our database: **Astronergy CHSM66N(DG)/F-BH-735** has higher module efficiency (**23.70%** vs **23.20%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Astronergy CHSM66N(DG)/F-BH-735 and Astronergy CHSM72N(DG)/F-BH 600? **Astronergy CHSM66N(DG)/F-BH-735** has a module efficiency of **23.70%**, while **Astronergy CHSM72N(DG)/F-BH 600** is **23.20%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Astronergy CHSM66N(DG)/F-BH-735 use vs Astronergy CHSM72N(DG)/F-BH 600? **Astronergy CHSM66N(DG)/F-BH-735** uses **TOPCon** cells; **Astronergy CHSM72N(DG)/F-BH 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 Astronergy CHSM66N(DG)/F-BH-735 and Astronergy CHSM72N(DG)/F-BH 600? **Astronergy CHSM66N(DG)/F-BH-735** has a **30 years** power warranty; **Astronergy CHSM72N(DG)/F-BH 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 Astronergy CHSM66N(DG)/F-BH-735 and Astronergy CHSM72N(DG)/F-BH 600 bifacial panels? Both **Astronergy CHSM66N(DG)/F-BH-735** and **Astronergy CHSM72N(DG)/F-BH 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 - [Astronergy CHSM66N(DG)/F-BH-735 vs Astronergy CHSM66N(DG)/F-BH-730](https://comparepv.com/compare/astronergy-chsm66n-dg-f-bh-735/astronergy-chint-new-energy-technology-co-ltd-chsm66n-dg-f-bh-730) - One difference: module efficiency - [Astronergy CHSM66N(DG)/F-BH-735 vs Astronergy CHSM66N(DG)/F-BH-725](https://comparepv.com/compare/astronergy-chsm66n-dg-f-bh-735/astronergy-chint-new-energy-technology-co-ltd-chsm66n-dg-f-bh-725) - 3 differences, the largest is module efficiency - [Astronergy CHSM66N(DG)/F-BH-735 vs Astronergy CHSM66N(DG)/F-BH-720](https://comparepv.com/compare/astronergy-chsm66n-dg-f-bh-735/astronergy-chint-new-energy-technology-co-ltd-chsm66n-dg-f-bh-720) - 3 differences, the largest is module efficiency - [Astronergy CHSM66N(DG)/F-BH-735 vs Astronergy CHSM66N(DG)/F-BH-715](https://comparepv.com/compare/astronergy-chsm66n-dg-f-bh-735/astronergy-chint-new-energy-technology-co-ltd-chsm66n-dg-f-bh-715) - 3 differences, the largest is module efficiency - [Astronergy CHSM66N(DG)/F-BH-735 vs Astronergy CHSM66N(DG)/F-BH-710](https://comparepv.com/compare/astronergy-chsm66n-dg-f-bh-735/astronergy-chint-new-energy-technology-co-ltd-chsm66n-dg-f-bh-710) - 4 differences, the largest is module efficiency - [Astronergy CHSM72N(DG)/F-BH 600 vs Astronergy CHSM78N(DG)/F-BH-650](https://comparepv.com/compare/astronergy-chsm72n-dg-f-bh-600/astronergy-chint-new-energy-technology-co-ltd-chsm78n-dg-f-bh-650) - 7 differences, the largest is rated power --- Source: https://comparepv.com/compare/astronergy-chsm66n-dg-f-bh-735/astronergy-chsm72n-dg-f-bh-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.
