According to our database: **HT-SAAE HT54-18X(ND)-F **430 W**** has higher module efficiency (**22.00%** vs **21.80%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of HT-SAAE HT54-18X(ND)-F 425W and HT-SAAE HT54-18X(ND)-F 430W? **HT-SAAE HT54-18X(ND)-F **425 W**** has a module efficiency of **21.80%**, while **HT-SAAE HT54-18X(ND)-F **430 W**** is **22.00%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does HT-SAAE HT54-18X(ND)-F 425W use vs HT-SAAE HT54-18X(ND)-F 430W? **HT-SAAE HT54-18X(ND)-F **425 W**** uses **TOPCon** cells; **HT-SAAE HT54-18X(ND)-F **430 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 HT-SAAE HT54-18X(ND)-F 425W and HT-SAAE HT54-18X(ND)-F 430W? **HT-SAAE HT54-18X(ND)-F **425 W**** has a **30 years** power warranty; **HT-SAAE HT54-18X(ND)-F **430 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 HT-SAAE HT54-18X(ND)-F 425W and HT-SAAE HT54-18X(ND)-F 430W bifacial panels? Both **HT-SAAE HT54-18X(ND)-F **425 W**** and **HT-SAAE HT54-18X(ND)-F **430 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 - [HT-SAAE HT54-18X(ND)-F 425W vs HT-SAAE HT54-18X(ND)-F 460W](https://comparepv.com/compare/ht-saae-ht54-18x-nd-f-425w/ht-saae-ht54-18x-nd-f-460w) - 11 differences, the largest is module efficiency - [HT-SAAE HT54-18X(ND)-F 425W vs HT-SAAE HT54-18X(ND)-F 455W](https://comparepv.com/compare/ht-saae-ht54-18x-nd-f-425w/ht-saae-ht54-18x-nd-f-455w) - 8 differences, the largest is module efficiency - [HT-SAAE HT54-18X(ND)-F 425W vs HT-SAAE HT54-18X(ND)-F 450W](https://comparepv.com/compare/ht-saae-ht54-18x-nd-f-425w/ht-saae-ht54-18x-nd-f-450w) - 6 differences, the largest is module efficiency - [HT-SAAE HT54-18X(ND)-F 425W vs HT-SAAE HT54-18X(ND)-F 445W](https://comparepv.com/compare/ht-saae-ht54-18x-nd-f-425w/ht-saae-ht54-18x-nd-f-445w) - 6 differences, the largest is module efficiency - [HT-SAAE HT54-18X(ND)-F 425W vs HT-SAAE HT54-18X(ND)-F 440W](https://comparepv.com/compare/ht-saae-ht54-18x-nd-f-425w/ht-saae-ht54-18x-nd-f-440w) - 5 differences, the largest is rated power - [HT-SAAE HT54-18X(ND)-F 425W vs HT-SAAE HT54-18X(ND)-F 435W](https://comparepv.com/compare/ht-saae-ht54-18x-nd-f-425w/ht-saae-ht54-18x-nd-f-435w) - 3 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/ht-saae-ht54-18x-nd-f-425w/ht-saae-ht54-18x-nd-f-430w 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.
