According to our database: **Astronergy CHSM54RN(DG)/F-BH-530** has higher module efficiency (**23.80%** vs **23.20%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Astronergy CHSM54RN(DG)/F-BH-515 and Astronergy CHSM54RN(DG)/F-BH-530? **Astronergy CHSM54RN(DG)/F-BH-515** has a module efficiency of **23.20%**, while **Astronergy CHSM54RN(DG)/F-BH-530** is **23.80%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Astronergy CHSM54RN(DG)/F-BH-515 use vs Astronergy CHSM54RN(DG)/F-BH-530? **Astronergy CHSM54RN(DG)/F-BH-515** uses **TOPCon** cells; **Astronergy CHSM54RN(DG)/F-BH-530** 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 CHSM54RN(DG)/F-BH-515 and Astronergy CHSM54RN(DG)/F-BH-530? **Astronergy CHSM54RN(DG)/F-BH-515** has a **30 years** power warranty; **Astronergy CHSM54RN(DG)/F-BH-530** 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 CHSM54RN(DG)/F-BH-515 and Astronergy CHSM54RN(DG)/F-BH-530 bifacial panels? Both **Astronergy CHSM54RN(DG)/F-BH-515** and **Astronergy CHSM54RN(DG)/F-BH-530** 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 CHSM54RN(DG)/F-BH-515 vs Astronergy CHSM54RN(DG)/F-BH-525](https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-515/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-525) - 3 differences, the largest is module efficiency - [Astronergy CHSM54RN(DG)/F-BH-515 vs Astronergy CHSM54RN(DG)/F-BH-520](https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-515/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-520) - One difference: module efficiency - [Astronergy CHSM54RN(DG)/F-BH-515 vs Astronergy CHSM54RN(DG)/F-BH-510](https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-515/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-510) - One difference: module efficiency - [Astronergy CHSM54RN(DG)/F-BH-515 vs Astronergy CHSM66N(DG)/F-BH-735](https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-515/astronergy-chsm66n-dg-f-bh-735) - 12 differences, the largest is rated power - [Astronergy CHSM54RN(DG)/F-BH-515 vs Astronergy CHSM66N(DG)/F-BH-730](https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-515/astronergy-chint-new-energy-technology-co-ltd-chsm66n-dg-f-bh-730) - 12 differences, the largest is rated power - [Astronergy CHSM54RN(DG)/F-BH-515 vs Astronergy CHSM66N(DG)/F-BH-725](https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-515/astronergy-chint-new-energy-technology-co-ltd-chsm66n-dg-f-bh-725) - 10 differences, the largest is rated power --- Source: https://comparepv.com/compare/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-515/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-530 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.
