According to our database: **Astronergy CHSM54RNs(DG)(BLH)/F-BH-**460 W**** has higher module efficiency (**23.00%** vs **22.00%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Astronergy CHSM54RNs(DG)(BLH)/F-BH-440W and Astronergy CHSM54RNs(DG)(BLH)/F-BH-460W? **Astronergy CHSM54RNs(DG)(BLH)/F-BH-**440 W**** has a module efficiency of **22.00%**, while **Astronergy CHSM54RNs(DG)(BLH)/F-BH-**460 W**** is **23.00%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Astronergy CHSM54RNs(DG)(BLH)/F-BH-440W use vs Astronergy CHSM54RNs(DG)(BLH)/F-BH-460W? **Astronergy CHSM54RNs(DG)(BLH)/F-BH-**440 W**** uses **TOPCon** cells; **Astronergy CHSM54RNs(DG)(BLH)/F-BH-**460 W**** 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 CHSM54RNs(DG)(BLH)/F-BH-440W and Astronergy CHSM54RNs(DG)(BLH)/F-BH-460W? **Astronergy CHSM54RNs(DG)(BLH)/F-BH-**440 W**** has a **30 years** power warranty; **Astronergy CHSM54RNs(DG)(BLH)/F-BH-**460 W**** 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 CHSM54RNs(DG)(BLH)/F-BH-440W and Astronergy CHSM54RNs(DG)(BLH)/F-BH-460W bifacial panels? Both **Astronergy CHSM54RNs(DG)(BLH)/F-BH-**440 W**** and **Astronergy CHSM54RNs(DG)(BLH)/F-BH-**460 W**** 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 CHSM54RNs(DG)(BLH)/F-BH-440W vs Astronergy CHSM54RNs(DG)(BLH)/F-BH-455W](https://comparepv.com/compare/astronergy-chsm54rns-dg-blh-f-bh-440w/astronergy-chsm54rns-dg-blh-f-bh-455w) - 3 differences, the largest is module efficiency - [Astronergy CHSM54RNs(DG)(BLH)/F-BH-440W vs Astronergy CHSM54RNs(DG)(BLH)/F-BH-450W](https://comparepv.com/compare/astronergy-chsm54rns-dg-blh-f-bh-440w/astronergy-chsm54rns-dg-blh-f-bh-450w) - 3 differences, the largest is module efficiency - [Astronergy CHSM54RNs(DG)(BLH)/F-BH-440W vs Astronergy CHSM54RNs(DG)(BLH)/F-BH-445W](https://comparepv.com/compare/astronergy-chsm54rns-dg-blh-f-bh-440w/astronergy-chsm54rns-dg-blh-f-bh-445w) - One difference: module efficiency - [Astronergy CHSM54RNs(DG)(BLH)/F-BH-440W vs Astronergy CHSM66N(DG)/F-BH-735](https://comparepv.com/compare/astronergy-chsm54rns-dg-blh-f-bh-440w/astronergy-chsm66n-dg-f-bh-735) - 13 differences, the largest is module efficiency - [Astronergy CHSM54RNs(DG)(BLH)/F-BH-440W vs Astronergy CHSM66N(DG)/F-BH-730](https://comparepv.com/compare/astronergy-chsm54rns-dg-blh-f-bh-440w/astronergy-chint-new-energy-technology-co-ltd-chsm66n-dg-f-bh-730) - 13 differences, the largest is module efficiency - [Astronergy CHSM54RNs(DG)(BLH)/F-BH-440W vs Astronergy CHSM66N(DG)/F-BH-725](https://comparepv.com/compare/astronergy-chsm54rns-dg-blh-f-bh-440w/astronergy-chint-new-energy-technology-co-ltd-chsm66n-dg-f-bh-725) - 13 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/astronergy-chsm54rns-dg-blh-f-bh-440w/astronergy-chsm54rns-dg-blh-f-bh-460w 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.
