According to our database: both panels are closely matched on key specs - the decision often comes down to price and local availability. See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Astronergy ASTRO N5s CHSM54N-HC-445W and Astronergy CHSM54N-HC-445W? **Astronergy ASTRO N5s CHSM54N-HC-**445 W**** has a module efficiency of **22.80%**, while **Astronergy CHSM54N-HC-**445 W**** is **22.80%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Astronergy ASTRO N5s CHSM54N-HC-445W use vs Astronergy CHSM54N-HC-445W? **Astronergy ASTRO N5s CHSM54N-HC-**445 W**** uses **TOPCon** cells; **Astronergy CHSM54N-HC-**445 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 ASTRO N5s CHSM54N-HC-445W and Astronergy CHSM54N-HC-445W? **Astronergy ASTRO N5s CHSM54N-HC-**445 W**** has a **30 years** power warranty; **Astronergy CHSM54N-HC-**445 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. ## Related comparisons - [Astronergy ASTRO N5s CHSM54N-HC-445W vs Astronergy CHSM54N-HC-445](https://comparepv.com/compare/astronergy-astro-n5s-chsm54n-hc-445w/astronergy-chint-new-energy-technology-co-ltd-chsm54n-hc-445) - One difference: cell technology - [Astronergy ASTRO N5s CHSM54N-HC-445W vs Astronergy CHSM54N-HC-440](https://comparepv.com/compare/astronergy-astro-n5s-chsm54n-hc-445w/astronergy-chint-new-energy-technology-co-ltd-chsm54n-hc-440) - 2 differences, the largest is module efficiency - [Astronergy ASTRO N5s CHSM54N-HC-445W vs Astronergy CHSM54N-HC-440W](https://comparepv.com/compare/astronergy-astro-n5s-chsm54n-hc-445w/astronergy-chint-new-energy-technology-co-ltd-chsm54n-hc-440w) - One difference: module efficiency - [Astronergy ASTRO N5s CHSM54N-HC-445W vs Astronergy CHSM54N(BL)-HC 440W](https://comparepv.com/compare/astronergy-astro-n5s-chsm54n-hc-445w/astronergy-chint-new-energy-technology-co-ltd-chsm54n-bl-hc-440w) - One difference: module efficiency - [Astronergy ASTRO N5s CHSM54N-HC-445W vs Astronergy ASTRO N5s CHSM54N-HC-440W](https://comparepv.com/compare/astronergy-astro-n5s-chsm54n-hc-445w/astronergy-astro-n5s-chsm54n-hc-440w) - One difference: module efficiency - [Astronergy ASTRO N5s CHSM54N-HC-445W vs Astronergy CHSM54N-HC-435](https://comparepv.com/compare/astronergy-astro-n5s-chsm54n-hc-445w/astronergy-chint-new-energy-technology-co-ltd-chsm54n-hc-435) - 4 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/astronergy-astro-n5s-chsm54n-hc-445w/astronergy-chint-new-energy-technology-co-ltd-chsm54n-hc-445w 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.
