According to our database: **GL Solar HY-NT10/72GDF-**595 W**** has higher module efficiency (**23.00%** vs **22.40%**); **GL Solar 3SHBGH-C#-635** tolerates heat better (temp coeff **-0.260%/°C** vs **-0.290%/°C**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of GL Solar 3SHBGH-C#-635 and GL Solar HY-NT10/72GDF-595W? **GL Solar 3SHBGH-C#-635** has a module efficiency of **22.40%**, while **GL Solar HY-NT10/72GDF-**595 W**** is **23.00%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does GL Solar 3SHBGH-C#-635 use vs GL Solar HY-NT10/72GDF-595W? **GL Solar 3SHBGH-C#-635** uses **HJT** cells; **GL Solar HY-NT10/72GDF-**595 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 GL Solar 3SHBGH-C#-635 and GL Solar HY-NT10/72GDF-595W? **GL Solar 3SHBGH-C#-635** has a **30 years** power warranty; **GL Solar HY-NT10/72GDF-**595 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 GL Solar 3SHBGH-C#-635 and GL Solar HY-NT10/72GDF-595W bifacial panels? Both **GL Solar 3SHBGH-C#-635** and **GL Solar HY-NT10/72GDF-**595 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 - [GL Solar 3SHBGH-C#-635 vs GL Solar 3SHBGH-C#-640](https://comparepv.com/compare/gl-solar-3shbgh-c-635/gl-solar-3shbgh-c-640) - One difference: module efficiency - [GL Solar 3SHBGH-C#-635 vs GL Solar 3SHBGH-C#-630](https://comparepv.com/compare/gl-solar-3shbgh-c-635/gl-solar-3shbgh-c-630) - The same specification on paper - [GL Solar 3SHBGH-C#-635 vs GL Solar 3SHBGH-C#-625](https://comparepv.com/compare/gl-solar-3shbgh-c-635/gl-solar-3shbgh-c-625) - 3 differences, the largest is module efficiency - [GL Solar 3SHBGH-C#-635 vs GL Solar 3SHBGH-C#-620](https://comparepv.com/compare/gl-solar-3shbgh-c-635/gl-solar-3shbgh-c-620) - 3 differences, the largest is module efficiency - [GL Solar 3SHBGH-C#-635 vs GL Solar 3SHBGH-C#-615](https://comparepv.com/compare/gl-solar-3shbgh-c-635/gl-solar-3shbgh-c-615) - 3 differences, the largest is module efficiency - [GL Solar 3SHBGH-C#-635 vs GL Solar 3SHBGH-C#-610](https://comparepv.com/compare/gl-solar-3shbgh-c-635/gl-solar-3shbgh-c-610) - 5 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/gl-solar-3shbgh-c-635/gl-solar-hy-nt10-72gdf-595w 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.
