According to our database: **Hanersun HN18RB-54HT**500 W**** has higher module efficiency (**24.50%** vs **23.80%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Hanersun HN18RB-54HT485W and Hanersun HN18RB-54HT500W? **Hanersun HN18RB-54HT**485 W**** has a module efficiency of **23.80%**, while **Hanersun HN18RB-54HT**500 W**** is **24.50%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Hanersun HN18RB-54HT485W use vs Hanersun HN18RB-54HT500W? **Hanersun HN18RB-54HT**485 W**** uses **Back Contact** cells; **Hanersun HN18RB-54HT**500 W**** uses **Back Contact**. 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 HN18RB-54HT485W and Hanersun HN18RB-54HT500W? **Hanersun HN18RB-54HT**485 W**** has a **30 years** power warranty; **Hanersun HN18RB-54HT**500 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 HN18RB-54HT485W and Hanersun HN18RB-54HT500W bifacial panels? Both **Hanersun HN18RB-54HT**485 W**** and **Hanersun HN18RB-54HT**500 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 - [Hanersun HN18RB-54HT485W vs Hanersun HN18RB-54HT495W](https://comparepv.com/compare/hanersun-hn18rb-54ht485w/hanersun-hn18rb-54ht495w) - 3 differences, the largest is module efficiency - [Hanersun HN18RB-54HT485W vs Hanersun HN18RB-54HTB495W](https://comparepv.com/compare/hanersun-hn18rb-54ht485w/hanersun-hn18rb-54htb495w) - 4 differences, the largest is module efficiency - [Hanersun HN18RB-54HT485W vs Hanersun HN18RB-54HT490W](https://comparepv.com/compare/hanersun-hn18rb-54ht485w/hanersun-hn18rb-54ht490w) - One difference: module efficiency - [Hanersun HN18RB-54HT485W vs Hanersun HN18RB-54HTB490W](https://comparepv.com/compare/hanersun-hn18rb-54ht485w/hanersun-hn18rb-54htb490w) - 2 differences, the largest is product warranty - [Hanersun HN18RB-54HT485W vs Hanersun HN18RB-54HTB485W](https://comparepv.com/compare/hanersun-hn18rb-54ht485w/hanersun-hn18rb-54htb485w) - One difference: product warranty - [Hanersun HN18RB-54HT485W vs Hanersun HN18RB-54HT480W](https://comparepv.com/compare/hanersun-hn18rb-54ht485w/hanersun-hn18rb-54ht480w) - One difference: module efficiency --- Source: https://comparepv.com/compare/hanersun-hn18rb-54ht485w/hanersun-hn18rb-54ht500w 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.
