According to our database: **AIKO AIKO-A775-GRH78Dw** has higher module efficiency (**24.10%** vs **23.23%**); **Luxor Solar LX-715M/210-132+ GG** tolerates heat better (temp coeff **-0.240%/°C** vs **-0.260%/°C**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of AIKO AIKO-A775-GRH78Dw and Luxor Solar LX-715M/210-132+ GG? **AIKO AIKO-A775-GRH78Dw** has a module efficiency of **24.10%**, while **Luxor Solar LX-715M/210-132+ GG** is **23.23%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does AIKO AIKO-A775-GRH78Dw use vs Luxor Solar LX-715M/210-132+ GG? **AIKO AIKO-A775-GRH78Dw** uses **Back Contact** cells; **Luxor Solar LX-715M/210-132+ GG** 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 AIKO AIKO-A775-GRH78Dw and Luxor Solar LX-715M/210-132+ GG? **AIKO AIKO-A775-GRH78Dw** has a **30 years** power warranty; **Luxor Solar LX-715M/210-132+ GG** 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 AIKO AIKO-A775-GRH78Dw and Luxor Solar LX-715M/210-132+ GG bifacial panels? Both **AIKO AIKO-A775-GRH78Dw** and **Luxor Solar LX-715M/210-132+ GG** 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 - [AIKO AIKO-A775-GRH78Dw vs AIKO AIKO-A805-GRH78Dw](https://comparepv.com/compare/aiko-aiko-a775-grh78dw/aiko-aiko-a805-grh78dw) - 3 differences, the largest is module efficiency - [AIKO AIKO-A775-GRH78Dw vs AIKO AIKO-A800-GRH78Dw](https://comparepv.com/compare/aiko-aiko-a775-grh78dw/aiko-aiko-a800-grh78dw) - 3 differences, the largest is module efficiency - [AIKO AIKO-A775-GRH78Dw vs AIKO AIKO-A795-GRH78Dw](https://comparepv.com/compare/aiko-aiko-a775-grh78dw/aiko-aiko-a795-grh78dw) - 3 differences, the largest is module efficiency - [AIKO AIKO-A775-GRH78Dw vs AIKO AIKO-A790-GRH78Dw](https://comparepv.com/compare/aiko-aiko-a775-grh78dw/aiko-aiko-a790-grh78dw) - 3 differences, the largest is module efficiency - [AIKO AIKO-A775-GRH78Dw vs AIKO AIKO-A785-GRH78Dw](https://comparepv.com/compare/aiko-aiko-a775-grh78dw/aiko-aiko-a785-grh78dw) - 3 differences, the largest is module efficiency - [AIKO AIKO-A775-GRH78Dw vs AIKO AIKO-A780-GRH78Dw](https://comparepv.com/compare/aiko-aiko-a775-grh78dw/aiko-aiko-a780-grh78dw) - One difference: module efficiency --- Source: https://comparepv.com/compare/aiko-aiko-a775-grh78dw/luxor-solar-lx-715m-210-132-gg-1 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.
