According to our database: **Astronergy CHSM48RN(DG)(BLH)/F-BH-465** has higher module efficiency (**23.30%** vs **22.80%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Astronergy CHSM48RN(DG)(BLH)/F-BH-455 and Astronergy CHSM48RN(DG)(BLH)/F-BH-465? **Astronergy CHSM48RN(DG)(BLH)/F-BH-455** has a module efficiency of **22.80%**, while **Astronergy CHSM48RN(DG)(BLH)/F-BH-465** is **23.30%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Astronergy CHSM48RN(DG)(BLH)/F-BH-455 use vs Astronergy CHSM48RN(DG)(BLH)/F-BH-465? **Astronergy CHSM48RN(DG)(BLH)/F-BH-455** uses **TOPCon** cells; **Astronergy CHSM48RN(DG)(BLH)/F-BH-465** 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 CHSM48RN(DG)(BLH)/F-BH-455 and Astronergy CHSM48RN(DG)(BLH)/F-BH-465? **Astronergy CHSM48RN(DG)(BLH)/F-BH-455** has a **30 years** power warranty; **Astronergy CHSM48RN(DG)(BLH)/F-BH-465** 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 CHSM48RN(DG)(BLH)/F-BH-455 and Astronergy CHSM48RN(DG)(BLH)/F-BH-465 bifacial panels? Both **Astronergy CHSM48RN(DG)(BLH)/F-BH-455** and **Astronergy CHSM48RN(DG)(BLH)/F-BH-465** 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 CHSM48RN(DG)(BLH)/F-BH-455 vs Astronergy CHSM54RN(DG)/F-BH-530](https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-blh-f-bh-455/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-530) - 10 differences, the largest is module efficiency - [Astronergy CHSM48RN(DG)(BLH)/F-BH-455 vs Astronergy CHSM54RN(DG)/F-BH-525](https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-blh-f-bh-455/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-525) - 10 differences, the largest is module efficiency - [Astronergy CHSM48RN(DG)(BLH)/F-BH-455 vs Astronergy CHSM54RN(DG)/F-BH-520](https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-blh-f-bh-455/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-520) - 10 differences, the largest is rated power - [Astronergy CHSM48RN(DG)(BLH)/F-BH-455 vs Astronergy CHSM54RN(DG)/F-BH-515](https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-blh-f-bh-455/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-515) - 9 differences, the largest is rated power - [Astronergy CHSM48RN(DG)(BLH)/F-BH-455 vs Astronergy CHSM54RN(DG)/F-BH-510](https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-blh-f-bh-455/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-510) - 7 differences, the largest is rated power - [Astronergy CHSM48RN(DG)(BLH)/F-BH-455 vs Astronergy CHSM48RN(DG)(BLH)/F-BH-470](https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-blh-f-bh-455/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-blh-f-bh-470) - 3 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-blh-f-bh-455/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-blh-f-bh-465 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.
