According to our database: **Hyundai HiT-H520LF-FB(ZB)** has higher module efficiency (**23.40%** vs **22.80%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Hyundai HiT-H455LE-FB(ZB) and Hyundai HiT-H520LF-FB(ZB)? **Hyundai HiT-H455LE-FB(ZB)** has a module efficiency of **22.80%**, while **Hyundai HiT-H520LF-FB(ZB)** is **23.40%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Hyundai HiT-H455LE-FB(ZB) use vs Hyundai HiT-H520LF-FB(ZB)? **Hyundai HiT-H455LE-FB(ZB)** uses **HJT** cells; **Hyundai HiT-H520LF-FB(ZB)** uses **HJT**. 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 Hyundai HiT-H455LE-FB(ZB) and Hyundai HiT-H520LF-FB(ZB)? **Hyundai HiT-H455LE-FB(ZB)** has a **30 years** power warranty; **Hyundai HiT-H520LF-FB(ZB)** 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 Hyundai HiT-H455LE-FB(ZB) and Hyundai HiT-H520LF-FB(ZB) bifacial panels? Both **Hyundai HiT-H455LE-FB(ZB)** and **Hyundai HiT-H520LF-FB(ZB)** 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 - [Hyundai HiT-H455LE-FB(ZB) vs Hyundai HiT-H460LE-FB(ZB)](https://comparepv.com/compare/hyundai-hit-h455le-fb-zb/hyundai-hit-h460le-fb-zb) - One difference: module efficiency - [Hyundai HiT-H455LE-FB(ZB) vs Hyundai HiT-H450LE-FB(ZB)](https://comparepv.com/compare/hyundai-hit-h455le-fb-zb/hyundai-hit-h450le-fb-zb) - One difference: module efficiency - [Hyundai HiT-H455LE-FB(ZB) vs Hyundai HiT-H445LE-FB(ZB)](https://comparepv.com/compare/hyundai-hit-h455le-fb-zb/hyundai-hit-h445le-fb-zb) - 3 differences, the largest is module efficiency - [Hyundai HiT-H455LE-FB(ZB) vs Hyundai HiT-H440LE-FB(ZB)](https://comparepv.com/compare/hyundai-hit-h455le-fb-zb/hyundai-hit-h440le-fb-zb) - 3 differences, the largest is module efficiency - [Hyundai HiT-H520LF-FB(ZB) vs Hyundai HiT-H515LF-FB(ZB)](https://comparepv.com/compare/hyundai-hit-h520lf-fb-zb/hyundai-hit-h515lf-fb-zb) - One difference: module efficiency - [Hyundai HiT-H520LF-FB(ZB) vs Hyundai HiT-H510LF-FB(ZB)](https://comparepv.com/compare/hyundai-hit-h520lf-fb-zb/hyundai-hit-h510lf-fb-zb) - 3 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/hyundai-hit-h455le-fb-zb/hyundai-hit-h520lf-fb-zb 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.
