According to our database: **Astronergy CHSM66N(DG)/F-BH-735** has higher module efficiency (**23.70%** vs **21.90%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Astronergy CHSM72N-HC-565 and Astronergy CHSM66N(DG)/F-BH-735? **Astronergy CHSM72N-HC-565** has a module efficiency of **21.90%**, while **Astronergy CHSM66N(DG)/F-BH-735** is **23.70%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Astronergy CHSM72N-HC-565 use vs Astronergy CHSM66N(DG)/F-BH-735? **Astronergy CHSM72N-HC-565** uses **TOPCon** cells; **Astronergy CHSM66N(DG)/F-BH-735** 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 CHSM72N-HC-565 and Astronergy CHSM66N(DG)/F-BH-735? **Astronergy CHSM72N-HC-565** has a **30 years** power warranty; **Astronergy CHSM66N(DG)/F-BH-735** 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 CHSM72N-HC-565 and Astronergy CHSM66N(DG)/F-BH-735 bifacial panels? **Astronergy CHSM66N(DG)/F-BH-735** is bifacial (captures light from both faces); **Astronergy CHSM72N-HC-565** is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath. ## Related comparisons - [Astronergy CHSM72N-HC-565 vs Astronergy CHSM72N-HC-580](https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm72n-hc-565/astronergy-chint-new-energy-technology-co-ltd-chsm72n-hc-580) - 3 differences, the largest is module efficiency - [Astronergy CHSM72N-HC-565 vs Astronergy CHSM72N-HC-575](https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm72n-hc-565/astronergy-chint-new-energy-technology-co-ltd-chsm72n-hc-575) - 3 differences, the largest is module efficiency - [Astronergy CHSM72N-HC-565 vs Astronergy CHSM72N-HC-570](https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm72n-hc-565/astronergy-chint-new-energy-technology-co-ltd-chsm72n-hc-570) - One difference: module efficiency - [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 --- Source: https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm72n-hc-565/astronergy-chsm66n-dg-f-bh-735 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.
