According to our database: **Hanersun HN18N-72HT**590 W**** has higher module efficiency (**22.80%** vs **22.60%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Hanersun HN18N-72H585W and Hanersun HN18N-72HT590W? **Hanersun HN18N-72H**585 W**** has a module efficiency of **22.60%**, while **Hanersun HN18N-72HT**590 W**** is **22.80%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Hanersun HN18N-72H585W use vs Hanersun HN18N-72HT590W? **Hanersun HN18N-72H**585 W**** uses **TOPCon** cells; **Hanersun HN18N-72HT**590 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 Hanersun HN18N-72H585W and Hanersun HN18N-72HT590W? **Hanersun HN18N-72H**585 W**** has a **30 years** power warranty; **Hanersun HN18N-72HT**590 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 Hanersun HN18N-72H585W and Hanersun HN18N-72HT590W bifacial panels? **Hanersun HN18N-72HT**590 W**** is bifacial (captures light from both faces); **Hanersun HN18N-72H**585 W**** is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath. ## Related comparisons - [Hanersun HN18N-72H585W vs Hanersun HN18N-72HT600W](https://comparepv.com/compare/hanersun-hn18n-72h585w/hanersun-hn18n-72ht600w) - 7 differences, the largest is module efficiency - [Hanersun HN18N-72H585W vs Hanersun HN18N-72H595W](https://comparepv.com/compare/hanersun-hn18n-72h585w/hanersun-hn18n-72h595w) - 3 differences, the largest is module efficiency - [Hanersun HN18N-72H585W vs Hanersun HN18N-72HT595W](https://comparepv.com/compare/hanersun-hn18n-72h585w/hanersun-hn18n-72ht595w) - 7 differences, the largest is weight - [Hanersun HN18N-72H585W vs Hanersun HN18N-72H590W](https://comparepv.com/compare/hanersun-hn18n-72h585w/hanersun-hn18n-72h590w) - One difference: module efficiency - [Hanersun HN18N-72H585W vs Hanersun HN18-72HT585W](https://comparepv.com/compare/hanersun-hn18n-72h585w/hanersun-hn18-72ht585w) - 5 differences, the largest is temperature coefficient - [Hanersun HN18N-72H585W vs Hanersun HN18-72H585W](https://comparepv.com/compare/hanersun-hn18n-72h585w/hanersun-hn18-72h585w) - 5 differences, the largest is performance warranty --- Source: https://comparepv.com/compare/hanersun-hn18n-72h585w/hanersun-hn18n-72ht590w 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.
