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 Runergy HY-DH108N8-445 and Runergy HY-DH108N8B-445? **Runergy HY-DH108N8-445** has a module efficiency of **22.80%**, while **Runergy HY-DH108N8B-445** is **22.80%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Runergy HY-DH108N8-445 use vs Runergy HY-DH108N8B-445? **Runergy HY-DH108N8-445** uses **N-type** cells; **Runergy HY-DH108N8B-445** uses **N-type**. 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 Runergy HY-DH108N8-445 and Runergy HY-DH108N8B-445? **Runergy HY-DH108N8-445** has a **30 years** power warranty; **Runergy HY-DH108N8B-445** 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 Runergy HY-DH108N8-445 and Runergy HY-DH108N8B-445 bifacial panels? Both **Runergy HY-DH108N8-445** and **Runergy HY-DH108N8B-445** 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 - [Runergy HY-DH108N8-445 vs Runergy HY-DH108N11-530](https://comparepv.com/compare/runergy-hy-dh108n8-445/runergy-hy-dh108n11-530) - 11 differences, the largest is module efficiency - [Runergy HY-DH108N8-445 vs Runergy HY-DH108N11-525](https://comparepv.com/compare/runergy-hy-dh108n8-445/runergy-hy-dh108n11-525) - 10 differences, the largest is module efficiency - [Runergy HY-DH108N8-445 vs Runergy HY-DH108N11-520](https://comparepv.com/compare/runergy-hy-dh108n8-445/runergy-hy-dh108n11-520) - 9 differences, the largest is rated power - [Runergy HY-DH108N8-445 vs Runergy HY-DH108N11-515](https://comparepv.com/compare/runergy-hy-dh108n8-445/runergy-hy-dh108n11-515) - 9 differences, the largest is rated power - [Runergy HY-DH108N8-445 vs Runergy HY-DH108N11-510](https://comparepv.com/compare/runergy-hy-dh108n8-445/runergy-hy-dh108n11-510) - 7 differences, the largest is rated power - [Runergy HY-DH108N8-445 vs Runergy HY-DH108N11-505](https://comparepv.com/compare/runergy-hy-dh108n8-445/runergy-hy-dh108n11-505) - 6 differences, the largest is rated power --- Source: https://comparepv.com/compare/runergy-hy-dh108n8-445/runergy-hy-dh108n8b-445 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.
