According to our database: **Phono Solar PS725M13GFH-22/WSHW** has higher module efficiency (**23.34%** vs **22.86%**); **Phono Solar PS725M13GFH-22/WSHW** tolerates heat better (temp coeff **-0.240%/°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 Phono Solar PS725M13GFH-22/WSHW and Phono Solar PS710M13GFH-22/WNH? **Phono Solar PS725M13GFH-22/WSHW** has a module efficiency of **23.34%**, while **Phono Solar PS710M13GFH-22/WNH** is **22.86%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Phono Solar PS725M13GFH-22/WSHW use vs Phono Solar PS710M13GFH-22/WNH? **Phono Solar PS725M13GFH-22/WSHW** uses **HJT** cells; **Phono Solar PS710M13GFH-22/WNH** 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 Phono Solar PS725M13GFH-22/WSHW and Phono Solar PS710M13GFH-22/WNH? **Phono Solar PS725M13GFH-22/WSHW** has a **30 years** power warranty; **Phono Solar PS710M13GFH-22/WNH** 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 Phono Solar PS725M13GFH-22/WSHW and Phono Solar PS710M13GFH-22/WNH bifacial panels? Both **Phono Solar PS725M13GFH-22/WSHW** and **Phono Solar PS710M13GFH-22/WNH** 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 - [Phono Solar PS725M13GFH-22/WSHW vs Phono Solar PS730M13GFH-22/WSHW](https://comparepv.com/compare/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps725m13gfh-22-wshw/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps730m13gfh-22-wshw) - The same specification on paper - [Phono Solar PS725M13GFH-22/WSHW vs Phono Solar PS720M13GFH-22/WSHW](https://comparepv.com/compare/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps725m13gfh-22-wshw/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps720m13gfh-22-wshw) - The same specification on paper - [Phono Solar PS725M13GFH-22/WSHW vs Phono Solar PS715M13GFH-22/WSHW](https://comparepv.com/compare/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps725m13gfh-22-wshw/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps715m13gfh-22-wshw) - 3 differences, the largest is module efficiency - [Phono Solar PS725M13GFH-22/WSHW vs Phono Solar PS710M13GFH-22/WSHW](https://comparepv.com/compare/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps725m13gfh-22-wshw/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps710m13gfh-22-wshw) - 3 differences, the largest is module efficiency - [Phono Solar PS710M13GFH-22/WNH vs Phono Solar PS705M13GFH-22/WNH](https://comparepv.com/compare/phono-solar-technology-co-ltd-ps710m13gfh-22-wnh/phono-solar-technology-co-ltd-ps705m13gfh-22-wnh) - The same specification on paper - [Phono Solar PS710M13GFH-22/WNH vs Phono Solar PS700M13GFH-22/WNH](https://comparepv.com/compare/phono-solar-technology-co-ltd-ps710m13gfh-22-wnh/phono-solar-technology-co-ltd-ps700m13gfh-22-wnh) - 3 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps725m13gfh-22-wshw/phono-solar-technology-co-ltd-ps710m13gfh-22-wnh 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.
